FIELD OF THE INVENTIONThe present invention relates to wagering games and gaming machines and systems for presenting games.
BACKGROUND OF THE INVENTIONWager and amusement gaming continues to grow in popularity. Nonetheless, casinos and other establishments that offer wager based gaming face the challenge of developing new and exciting games in order to maintain player interest. One example of a popular game which is presented in both amusement and wager-based formats is the game of SLINGO (registered trademark of Slingo, Inc.). This game was originally developed well over a decade ago and is the subject of numerous patents. However, in order to not only maintain the interest of existing players of this original game and other games, but to draw additional players to this and other games, the inventors herein have developed a new and exciting games features which are applicable to this and other games.
SUMMARY OF THE INVENTIONOne aspect of the invention comprises methods of presenting and playing games. Another aspect of the invention comprises gaming machines and gaming systems for presenting at least one game.
In one embodiment of a game, a single game has the potential for multiple levels. Each level comprises a symbol matching event in which a set of base symbols are compared against a set of game symbols for potential matches. If a required minimum number of matches or other criteria are met, the game may continue to the next level. The game symbols may be displayed in rows, such as rows of a matrix having m rows by n columns of symbol positions. The base symbols may then be displayed in a row having n positions, where each base symbol in an individual nth position is compared to the corresponding game symbol in the same nth position.
In one embodiment, the game is played as a wagering game. Awards, such as credits representing monetary value, may be awarded for matches of individual game symbols and/or matches of patterns of game symbols.
As one example of a method, a wager is accepted from a player. A first row of n game symbols is then activated relative to a matrix of symbol positions. A row of base symbols having n positions is displayed. The base symbol in each nth position is then compared to the corresponding game symbol in the same position for potential symbol matches. One or more awards may be awarded for symbol matches. If a required number of symbol matches are not received relative to the first row of game symbols, the game may end. If a required number of symbol matches are received relative to the first row of game symbols, the game preferably continues by repeating the following sequence until there are no unactivated rows of symbol positions on the matrix: (1) activating a next row of game symbols relative to the matrix of symbol positions; (2) displaying a new set of base symbols; (3) comparing the base symbols and game symbols which are in corresponding positions for potential symbol matches; (4) awarding awards for symbol matches; (5) if a required number of symbol matches are not received relative to the next row of game symbols, ending the game; and (6) if a required number of symbol matches are received (or other advancing criteria are met) relative to the next row of game symbols, repeating steps (1)-(6).
Additional aspects of the invention comprise game features. The game features may be utilized with games of the invention or other games. For example, in one embodiment, awards for winning events in higher levels of the game may be higher than those in lower levels of the game. For example, matches of game symbols in a first row may yield a first range of awards, while matches of game symbols in a second row may yield a second higher range of awards.
In one embodiment, a game may include one or more wild symbols. A wild symbol may be matched to any game symbol. In one embodiment, the wild symbol may be a Joker which is displayed as one or more of the base symbols. A methodology may be applied to the application of a Joker to maximize the player's winnings. For example, Jokers may be matched to particular game symbols in a manner which yields high award symbol matching patterns or which match game symbols in higher levels (having higher awards associated therewith).
A game may also include mystery bonuses or prizes, as well as a game advance feature. In one embodiment, the game advances from one level to another if a required minimum number of symbol matches are received relative to a first level or row of game symbols. In another embodiment, a player might receive a game advance symbol, such as a frog, which causes the game to advance to the next level even if the required number of symbol matches is not received.
A wide variety of aspects of games, gaming machines and game features will be appreciated from the description herein. As detailed herein, one or more games offer a player substantial excitement relative to the potential of advancing through multiple levels of a game. This excitement is enhanced when the game is played as a wagering game offering the player opportunities for winnings.
Another aspect of the invention comprises games which include a symbol collection feature, such as games in which a player collects symbols during the play of a base game. In one embodiment, a player may collect one or more symbols during the play of a base portion of the game, which symbols may be used in the one or more bonus events. The collected symbols may preferably improve the probability of the player winning the one or more bonus events or improve the probability of the player achieving a higher payout or winnings as a result of play of the one or more bonus events.
Yet another aspect of the invention comprises games which permit a player to purchase symbols or game-extending features. In one embodiment, a player may purchase special symbols for use in improving the probability of their winning a bonus game. In another embodiment, a player may purchase spins or other game-extending or win-improving features for use in improving the probability of their winning a bonus game. The features might comprise, for example, free spins, wild symbols or other elements.
Further objects, features, and advantages of the present invention over the prior art will become apparent from the detailed description of the drawings which follows, when considered with the attached figures.
In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.
One aspect of the invention comprises methods of presenting and playing games using symbols or indicia. One embodiment of a game is a symbol matching game in which one or more sets or rows of base symbols are matched to sets or rows of game symbols. Preferably, the game has the potential for multiple levels such that if a player receives a requisite number of symbol matches in each level, the game advances sequentially to a next level.
Another aspect of the invention comprises games which include a symbol collection feature, such as games in which a player collects symbols during the play of a base game, which collected symbols may be used in the play of a bonus game.
Yet another aspect of the invention comprises games which permit a player to purchase symbols or game-extending features. In one embodiment, a player may purchase special symbols for use in improving the probability of their winning a game, such as a bonus game. In another embodiment, a player may purchase spins or other game-extending or win-improving features for use in improving the probability of their winning a game, such as a bonus game.
Further aspects of the invention comprise gaming machines and systems for implementing or presenting the games of the invention.
In accordance with the game, in a step S2, a first set of game symbols is displayed or made active related to a first set of positions. Preferably, the first set of game symbols comprise a sub-set of a larger set of symbols, or comprise the random distribution of a set of symbols. Such symbols may have various forms and may comprise letters, numbers, words, images or the like. In one embodiment, the symbols in the set of symbols may all be unique. In preferred embodiments, one or more of the symbols in the set of symbols may be duplicated or repeated. For example, the first set of game symbols may comprise five (5) symbols selected from a larger set of fifteen (15) symbols. In one embodiment, the first set of game symbols is displayed in a row of n columns. Preferably, there are at least 1 and more preferably, at least 5, columns.
In a step S3, a set of base symbols is displayed for matching to the first set of game symbols. In a preferred embodiment, the set of generated base symbols is equal in number to the symbols in the first set of game symbols. For example, if the first set of game symbols comprises a row of five (5) symbols, the set of base symbols comprises five (5) symbols. Preferably, the set of base symbols is randomly generated. The base symbols might be displayed or comprise symbols displayed by physical or video reels. For example, five base symbols might be displayed by five spinning reels.
In a preferred embodiment, symbols in the first set of game symbols and the set of base symbols are compared positionally. In one embodiment, the first set of game symbols and the set of base symbols are arranged into a row of n columns, and the symbols in each nth column are compared with one another.
In one embodiment of the game, the object is to match as many of the base symbols and game symbols which are in corresponding positions, as possible. As detailed below, awards may be provided for matches. Preferably a match occurs if the symbols in corresponding positions are the same.
In one embodiment of the game, if certain game criteria are met, then the game continues on to a next level or portion of the game. In a preferred embodiment, in a step S4, if a certain minimum number of matches are achieved relative to the first set of game symbols, the game continues with play of a second set of game symbols. For example, a player may be required to achieve at least one match relative to the first set of game symbols to advance the game to the next level and play the second set of game symbols. In that event, a second set of game symbols is displayed or rendered active, as in a step S5. Preferably, the second set of game symbols comprises the same number of symbols as the first set of game symbols. For example, the second set of game symbols may comprise a row of n columns of symbols. The second set of game symbols may be displayed adjacent the first set of game symbols, such as in a matrix directly above the first set of game symbols.
As illustrated in
Another set of base symbols is then displayed for matching to the second set of game symbols, as in a step S6. Preferably, this set of base symbols is randomly selected and so may differ from the first set of base symbols. Once again, the generated base symbols are compared to the second set of game symbols for potential matches. Awards may again be provided for matches. If a certain minimum number of matches are achieved relative to the second set of game symbols (or, as detailed below, other criteria are met), as in a step S7, the game may continue to a third set of game symbols. This process may repeat until all of the sets of game symbols are displayed, as in a step S8. For example, in one embodiment, a total of m rows by n columns of symbols may be displayed in a matrix format. The first set of game symbols may comprise a first row of n columns of symbols; the second set of game symbols may comprise the second row of n columns of game symbols, and so on. In a preferred embodiment, there may be twenty-five (25) symbols arranged into a five by five (5×5) matrix (though as described below there may be other numbers of symbols displayed in other formats, including matrices of other configurations/sizes).
If the player successfully advances through all of the levels of the game and/or if the requisite number of symbol matches are not received, then awards received for the game may be paid, as in step S9. As described in greater detail below, awards may be provided for symbol matches or other events. In one embodiment, the awards may comprise credits. The awards might also or instead comprise points, tangible goods, discounts, tickets, money (such as coins or paper currency) or the like. The game may then end at a step S10.
In accordance with the invention, a game is provided which includes a game “advance” feature. In particular, a single game has the potential to comprise multiple levels or portions. If a player achieves certain thresholds or requirements, the player may advance or move from a first level of the game through additional levels of the game. In this manner, a player is enticed to try and reach the final stage or level of the game. Further, the play of the game in levels progressing from a first level to a final level enhances the excitement of the game.
One embodiment of a preferred embodiment of a game in accordance with the invention will be described with reference to
In one embodiment, the game information comprises sets of game symbols to be matched, sets of generated base symbols, and bet and win information, among other information. In one embodiment, a matrix 20 of symbol positions is displayed. In a preferred embodiment, the matrix 20 has five (5) rows and five (5) columns for a total of twenty-five (25) positions.
In one embodiment, each of the positions of the matrix 20 has an associated symbol or indicia. Preferably, the symbols are randomly selected, such as by one or more random number generators. As detailed below, at the start of the game, only a first row 40 of symbols is active. Thus, the other symbols associated with the matrix may not yet be displayed or might be displayed in a different fashion (such as in a shaded fashion as shown in
In one embodiment, the symbols in the matrix may be referred to as the “game symbols” of symbols, in that these symbols do not change during the play of the game.
The game information also includes sets of symbols to be matched to the game symbols. In one embodiment, a row of base symbols 28 is displayed. In a preferred embodiment, this set of symbols 28 may change during the game. Preferably, there are a number of base symbols equal to the number of symbols in each set of game symbols, such as equal to the number of columns in the matrix 20. Thus, where the matrix 20 has five (5) columns, there are five (5) base symbols. In a preferred embodiment, the base symbols 28 are arranged into a row positioned below the matrix 20.
A payout range 22 may be indicated relative to one or more of the game symbols. In one embodiment, a payout range 22 is indicated relative to each row of symbols. For example, such may be indicated to the left or right side of each row of the matrix 20. The payout range 22 may indicate one or more values or a range of values for awards for matches of the designated symbols (such as the symbols in that row).
An award total 24 may be indicated. In one embodiment, an award total 24 may be indicated relative to each row of symbols, such as to the right of each row of symbols.
A variety of other information may also be displayed to the player. For example, various bet amount buttons 26 may be provided. These bet amount buttons 26 may permit a user to place wagers in particular amounts, such as amounts of 50 credits, 100 credits or the like, including a “max bet” which permits the player to place the maximum wager allowed by the game.
The interface may also display information such as the total number of credits belonging to the player 36, the number of credits won by the player for a particular portion of the game 37, a total win for the game 38, and a number of free spins 60.
In one embodiment, the game may offer one or more bonus awards. Such may comprise progressive awards which change in value over time. Information regarding these various awards may be displayed, such as in a progressive jackpot window 30 at the top of the interface.
Of course, the arrangement, content and appearance of the interface may vary. For example, the interface may utilize various artwork such as colors and themes. The size of the interface and the arrangement of the features thereof may vary.
As detailed below, a player may provide input to the game in various manners. In one embodiment, such may be by input to a touch screen relative to one or more of the buttons or areas of the interface. Input might also be provided to external devices such as physical buttons or the like.
In one embodiment, game play begins by a player placing a wager. In one embodiment, this may be by the player providing input to one of the bet amount buttons 26. Game play may then automatically be initiated or it may be initiated by a player providing input to a “spin” or similar button 32. In one preferred embodiment, if a player places a maximum wager, such as by pressing the “MAX BET” button, the game automatically starts. On the other hand, if a player places a wager less than the maximum wager, such as by placing a wager of an amount such as 50, 100, 150, etc. credits, then the player may be required to also press the Spin button 32 to then start the game.
In a first portion or level of the game, only a first row 40 of the matrix 20 is active. As indicated above, the symbols of that row 40 may be highlighted or otherwise designated to indicate to the player the active status thereof. In one embodiment, the player is also provided with information regarding the number of matches to the symbols of the first row which are necessary to advance in the game and the value of awards for matches. In one embodiment, one or more matches are required to advance past the first level of the game.
A set of base symbols 28 is displayed, such as below the first row 40 of game symbols. The base symbols 28 may be displayed in alignment with the symbols in the first row 40. Preferably, the symbols in corresponding positions of the base symbols 28 and the first row 40 of game symbols are compared to determine if they match. In the embodiment illustrated, this comprises comparing the symbols in the same columns 50, 52, 54, 56, 58. Thus, the symbol in the first position of the base symbols 28 is compared to the symbol in the first position of the first row 40 of symbols (i.e. the symbols in the first column 50 are compared). If the symbols match, a match may be declared or indicated, such as by highlighting the matched symbol in the first row 40. In the example illustrated in
As indicated above, the game may be played with a variety of symbols. Such may comprise numbers, letters, icons or images, or combinations thereof. In one preferred embodiment, the game is played with the numbers 1-75. The numbers 1-15 are used relative to the first column, the numbers 16-30 are used relative to the second column, and so on. Thus, one or more random number generators may be used to select a number from the group 1-15 for each of the positions in the first column. In one embodiment, the numbers in each column are unique. In this configuration, the sets of base symbols are selected from the same groups of numbers. For example, each time a set of base symbols is generated for matching to each row of game symbols in the matrix, the base symbols are selected from the set 1-15 as to the first position, 16-30 as to the second position, etc.
In one embodiment, awards are randomly generated and assigned to each position in the matrix 20. The awards may be selected from the indicated value range 22. For example, relative to the first row 40 of game symbols, awards may be randomly selected from the range of 5 to 20 credits for each symbol position. In a preferred embodiment, the range for each row or level of the game increases relative to the previous row or level, and the particular awards or ranges are preferably higher for games where the player places a higher wager.
In the event of a match, the number of credits (or other value, award or additional game feature) which was assigned to that symbol position is preferably awarded to the player. The particular award for a match may be shown, such as in the matrix 20 adjacent to the symbol which was matched, as illustrated in
In the event a player meets the required criteria for the first level, the player may advance to a second level of the game. In the preferred embodiment, as indicated, this criterion comprises a minimum number of symbol matches. As described above, however, a player might advance based upon other criteria, such as the appearance of a game advance symbol.
If the player does not meet the required criteria, such as the required minimum number of symbol matches, the game preferably ends. If the player does meet the required criteria, the game preferably moves or advances to the next portion or level of the game. Preferably, at this time, a second row 42 of game symbols becomes active, as illustrated in
A second set of base symbols 28 is then generated for comparison to the second row 42 of game symbols. The second set of base symbols 28 is preferably again randomly selected and compared position by position to the game symbols in the second row 42. As with the first row 40, matches preferably have associated awards and the total of the awards for the row may be indicated to the player.
In a preferred embodiment of the invention, once a row or level of game symbols has been activated, the row or level remains active and can be matched through the entirety of the game. In this manner, a player may receive matches relative to symbols in earlier activated rows or levels and receive additional awards, including improving the probability of receiving patterns or combinations of matches across multiple rows or levels. For example, as illustrated in FIG. 2B, the number “36” in the second spin of the base symbols 28 does not match the corresponding number “43” in the second row 42 of game symbols, but it does match number “36” in the previously activated first row 40 of game symbols. As a result, an additional award of 5 credits has been paid to the player for that match.
Once again, if certain criteria are met, the game preferably continues. In one embodiment, this again comprises a certain minimum number of matches. Preferably, this number is equal to or greater than that required to advance from the first row 40 of game symbols. For example, a single match may be required to advance from the first row 40, and two matches may be required to advance from the second row 42. If such a requirement is not met, the game preferably ends. If the requirement is met, the game preferably continues or advances to the next level.
In the configuration illustrated where there are five (5) rows, this game preferably continues in this fashion by the game either ending or continuing to the next level to a third row 44, a fourth row 46 and a fifth row 48, as illustrated in
Additional aspects of the invention will now be described in detail.
In one embodiment, a player keeps accrued winnings even if the game ends before the player reaches the final level. Thus, for example, if the player won 15 credits by matches relative to the first row 40, the player would retain those winnings regardless of how far the player advances in the game. In other embodiments of the game, however, the player might be required to reach the final level in order to win the awards accrued during the game.
In a preferred embodiment, the game comprises a single game with multiple levels. Thus, when a player places at least a minimum wager, the player has the opportunity to play the game through all of the levels without any additional wager. In other embodiment, the player might be required to place a wager to continue through each level.
In one embodiment, the game may include other types of awards. For example, awards might be represented by secondary symbols in the event of a match. In one embodiment, one or more gold coins (or other symbols) might be associated with game symbols or game symbol positions. If the player receives a match as to that symbol or that position, then the gold coin may be displayed to the player. Instead of a normal award, the player may receive a higher than normal award for that match. In one embodiment, that award might comprise a randomly selected value (such as from a pre-defined set of values like 10, 25, 50, 75, 100 or 200 credits). Such a value might be awarded directly, or it might be multiplied by the player's wager.
In one embodiment, a player may be awarded one or more free spins. Such spins may be indicated in a free spin area 60 of the interface. Free spins may be awarded based upon various criteria, including randomly and as a secondary award to a symbol match. In one embodiment, a player may utilize a free spin to obtain another set of base symbols relative to a particular level of the game. For example, a player may advance to the second level of the game, wherein the second row 42 of game symbols is activated. After a set of base symbols 28 is generated or activated, the player might have received only a single match. If two matches are required to advance from the second level to the third level of the game, the game would normally end. However, if the player has a free spin, the player may use that spin and to cause another set of base symbols 28 to be generated. That extra set of base symbols may result in additional matches of the game symbols in the second row 42. If so, the game may then advance to the next level (third row).
In one embodiment, if a player reaches the final level and the player has one or more free spins remaining, the free spin(s) may be used and the extra set of base symbols may be generated and may be compared to the game symbols in any of the rows or levels. This may result in additional matches and additional awards.
In one embodiment, a player may receive awards for combinations of symbol matches. In a preferred embodiment, a player receives an award for matching all of the symbols along a single row, a single column or a diagonal of the matrix. Such a combination of matches may be referred to as a SLINGO (registered trademark of Slingo, Inc.). The awards for such combinations of matches may vary. In one embodiment, the award for a diagonal SLINGO combination is higher than that for a vertical combination, which is in turn higher than that for a horizontal combination.
Further, awards might be provided for other patterns or combinations of symbol matches such as an “X” pattern as illustrated in
As indicated above, the interface may be configured to display a jackpot window 30. That window may display the amounts of one or more jackpots. The jackpots may comprise large payouts for particular events, such as the receipt of particular combinations of symbol matches. The jackpots might comprise fixed amounts or comprise variable amounts. For example, one or more of the jackpots might comprise progressive jackpots. Such jackpots may grow in value over time. The jackpots may be funded in various manners. For example, the jackpots may be funded from a portion of wagers at one gaming machine or a plurality of gaming machines, as is known in the art.
The game may include a variety of other features. In one embodiment, a player may be permitted to advance to the next level even if the minimum number of symbol matches is not obtained. In one embodiment the game may be configured to randomly generate an “advance” symbol relative to one or more of the symbols. The advance symbol might comprise a “frog” symbol. If the symbol is generated relative to a particular row, then the play of the game preferably automatically advances to the next level or row. In one embodiment, such a symbol may be received relative to any row except the last (fifth row 48 in this case). In a preferred configuration, if such a symbol were assigned to a position in the fifth row and a match occurred relative to that position thus triggering the symbol, the symbol is instead treated as a free spin award. In that event, the frog symbol would not appear, but instead the number of free spins would be incremented in the free spin area 60.
In one embodiment, the game may include wild symbols. Such symbols might comprise, for example, a Joker, as illustrated in
1) If a combination completes a progressive jackpot pattern, then this combination is given top priority;
2) If a combination enables the player to advance to the next row, this combination is given second priority;
3) If a combination completes one or more designated or selected symbol combinations, such as on or more SLINGO combinations (i.e. one or more rows, columns, or diagonal matches), then that combination is given third priority. The more of such combinations that are completed, the higher priority it gets over other combinations of this kind; and
4) Otherwise, a Joker(s) is placed in the highest row(s) possible.
In the event that two combinations are given equal priority, the routine will assign a point score to each Joker according to which row each Joker in the combination will be placed in. The higher the row, the higher the score.
As one example, a Joker may be displayed in the first and third positions or columns of the base symbols. Assume that the first Joker can only be placed at either the second, third or fourth row and that the middle Joker can only be placed in the third row. Also, assume that a criss-cross progressive jackpot would be completed if the center position of the matrix were completed (which is the only position the second Joker can be placed). In this event, there are three possible combinations:
1) First Joker placed at row two, second Joker placed at row three;
2) First Joker placed at row three, second Joker placed at row three; or
3) First Joker placed at row four, second Joker placed at row three.
Each combination will complete the criss-cross pattern. However, in accordance with the above-described preferences, two points are assigned to the first combination since the first Joker will be placed in the second row, three points for the second combination, and so on. The third combination would thus ultimately be chosen since it completes the criss-cross pattern while maximizing the player's winnings by placing the non-pattern-completing Joker at the highest row possible (since winnings for symbol matches have a higher range for higher levels or rows).
When determining the best combination, it is important to note that the gaming machine can account for matches made by other base symbols. All other symbol matches are processed first, even though they may be made subsequent the positions with Jokers.
In another embodiment of the invention, a game may include a mystery bonus. Such a bonus may be indicated by an animated character such as a Cherub. The Cherub may appear randomly, such as by being displayed on the interface after a set of base symbols are displayed or after a player has unsuccessfully completed a level (so that the game would otherwise end). In one embodiment, the Cherub could result in additional awards to the player and potentially prevent the game from ending. When the Cherub is displayed, it could do some or all of the following features: (1) match game symbols of the matrix 20; (2) add. Jokers to the base symbols 28; (3) automatically advance the player to the next row or level of the game; and (4) award one or more free spins (such as by increasing the free spin count in the free spin area 60), thus permitting the display of a new set of base symbols.
As one example, the Cherub could be displayed on the screen and be configured to randomly select symbols for matching to the active game numbers displayed in the matrix 20. Such additional matches yield additional winnings to the player and may result in the player receiving a required number of matches as to the current row to advance to the next level/row. For example, the Cherub might be animated and use a wand to select particular displayed game symbols, at random, that automatically are designated as matches (even though they were never matched by a base symbol).
As another example, the Cherub could be displayed on the screen and be configured to add one or more Jokers to a base symbol set. Those Jokers could then be used to match one or more game symbols as in the manner above, again triggering additional awards for a player and potentially resulting in the player advancing to the next game level. The Cherub might add a single Joker or multiple Jokers. For example, the Cherub might be animated and use a wand to convert already displayed base symbols (such as numbers) into Jokers.
As another example, the Cherub could be displayed on the screen and award a player a free advance to the next level/row. When the Cherub does this; the matrix will increase by one (1) row and the player will automatically be given another spin, thus receiving an additional opportunity for matches. This feature would only be active if the player has not already reached the final level or row.
As a final example, the Cherub could be displayed on the screen and cause another set of base symbols to be displayed relative to a particular row of game symbols (i.e. a “free spin”). The new base symbols may result in additional matches of game symbols in the active row, yielding additional awards and potentially advancement to the next level/row. For example, the Cherub might be animated to use a wand to cause the base symbols to rotate or spin to a new set of base symbols.
The Cherub may be configured to appear only once during the game and may accomplish one or more features, such as those described above. In order for the Cherub to be active, a player may be required to place a wager of a certain size. In another embodiment, the player may be required to place a side of bonus wager in order to activate the feature. For example, the player might be required to place an additional wager of 50 credits to activate the feature above and beyond the base wager the player places.
As indicated, a player may be permitted to place wagers in various amounts. In one embodiment, the size of a player's wager may determine the number of game features which are activated. For example, a wager of 50 credits may activate the “Jokers” feature; a wager of 100 credits may further activate the “Gold Coins” feature; a wager of 150 credits may activate the “Frog” feature; a wager of 200 credits may activate the “Free Spins” feature; and a maximum wager of 250 credits may activate the “Jackpots” feature. Of course, the size of the wagers and the types of features which are activated may vary.
In one embodiment, presentation of the game may be automatic and may not require player input beyond the player being required to place a wager and, in some embodiments, starting the game via the “spin” button or the like. For example, the game may automatically display the base symbols and compare those symbols to the first row of game symbols and indicate any matches. If the required number of matches is received, the game may automatically move to the second level, etc. In other embodiments, however, the player might be required to provide various inputs. For example, a player may be required to compare the base symbols to the game symbols and indicate matches, such as by providing input to a touch screen proximate to a matching symbol. A player might also be required to provide a “spin” input in order to initiate each level of the game. A player might also be required to provide input to utilize a free spin.
It will be appreciated that the game may comprise the play of various numbers of game symbols. For example, instead of a 5×5 matrix of game symbols, the matrix might be a 4×2, a 6×7, a 3×5, a 4×4, or an 8×8 matrix or the like. In addition, the number of game symbols in different rows could potentially vary. For example, there might only be three (3) game symbols in the first row, four (4) in the second row, and so on. In such event, the number of base symbols which are displayed may vary to match the corresponding number of game symbols in the active row.
It will also be appreciated that while the game may advance through rows of a matrix starting at the bottom of the matrix and working upwardly, the game might advance in other manners. For example, the rows could be played from top to bottom. In another embodiment, the sets of game and base symbols might be displayed in completely different fashions other than the displayed matrix configuration.
In one embodiment, the base symbols may be referred to as “spun” symbols. In particular, as detailed below, the base symbols might be displayed by one or more mechanical spinning reels. Alternatively, they might be displayed in graphical from via a video display in a manner which makes it appear that symbols are spinning and stopping at positions to display the base symbols. Of course, the base and game symbols may be displayed in various manners and via various mechanisms.
Another aspect of the invention comprises games and gaming machines having a symbol collection feature. In one embodiment of the invention, a game includes a symbol collection feature wherein a player may collect one or more symbols which may be used in the game. Preferably, a game has a base portion and one or more bonus events. A player may collect one or more symbols during the play of the base portion of the game, which symbols may be used in the one or more bonus events. The collected symbols may preferably improve the probability of the player winning the one or more bonus events or improve the probability of the player achieving a higher payout or winnings as a result of play of the one or more bonus events.
In one embodiment, the symbols which a player is permitted to collect may be referred to as “bonus symbols.” In a preferred embodiment, such symbols may only be collected during the play of a base game and are not be used in the formation of winning combinations or the like in the play of the base game.
The symbol collection feature of the invention may be applied to the game described above, variations of that game or other entirely different games. One embodiment of the symbol collection feature of the invention will be described with reference to the game described above and
As illustrated in
In a preferred embodiment, a player is permitted to collect the bonus symbols 200. In one embodiment, a player may collect at least one of each type of possible bonus symbol (i.e. the player may collect only one of the three “Extra Jokers” bonus symbols 200). In one embodiment, a player may only collect one of each particular type of bonus symbol, though in other embodiments a player might be permitted to collect multiples of each particular type of bonus symbol.
In a preferred embodiment, the bonus symbols 200 may not be used in the play of the base game. Thus, in a preferred embodiment the bonus symbols 200 are only collected during the base game and do not otherwise bear upon play of the base game.
As illustrated in
In one embodiment, collected bonus symbols 200 may be used by a player in a bonus or secondary event. Preferably, such a bonus or secondary event comprises a game or event other than the base game in which the bonus symbols are awarded or collected. Such a bonus or secondary event may use one or more different game symbols in the play thereof and preferably defines one or more winning outcomes which are different than the base game. In a preferred embodiment, the bonus event is presented to the player via a different interface or display than the main game (for example, the base game may be presented via one graphical interface and the bonus event may be presented via a different graphical interface and the base and bonus games might be presented on the same electronic or other display or via different displays). In a preferred embodiment, a bonus game or event is awarded or initiated without the requirement for an additional wager and comprises a portion of a single gaming event in that the bonus game is initiated or triggered as a result of an action or event in a base game. It is noted that not all base games may trigger a bonus event. Thus, it is possible for a player to play a base game and collect one or more bonus symbols which are ultimately not used or which are not usable because a bonus event is never triggered or initiated. In a preferred embodiment, bonus symbols collected during the play of one base game can be carried to a later base game if they are not used (such as if no bonus event is triggered during a first base game in which the bonus symbol is collected), and in such arrangement the collected bonus symbols may be displayed persistently or from game to game, thus permitting the player to see what bonus symbols have been collected and not used. In other embodiments, it is possible for the symbols to expire if they are not used. For example, if a player plays a first base game and does not trigger a bonus event, the player preferably loses any collected bonus symbols at the end of the first base game. When a player initiates a second or new base game, the player must then start over in attempting to collect bonus symbols.
Such bonus or secondary events may be triggered or initiated in various fashions.
As indicated, in a preferred embodiment, the bonus symbols 200 may improve the probability of the player obtaining a winning outcome in the bonus event, or achieving a winning outcome which has a higher award or winning payout. The particular effect of each bonus symbol 200 may vary. For example, in one variation of a bonus game, base symbols may again be displayed and matched against a matrix of player symbols. The player may again attempt to obtain certain matches, similar to the game described above, for a bonus winning outcome. However, if a “Devil” symbol is displayed as one of the base symbols, the bonus event may end. If the player had not yet achieved a winning combination of matches, for example, then the player would not win the bonus event. The above-referenced “Devil Protection” symbol 212, if collected by the player for use in the bonus event, may negate the Devil symbol and permit the game to continue. In that event, the player has a greater probability of winning the bonus event than if the player did not collect that symbol.
The particular bonus symbols and their effect may vary, including depending on the particular game. In one embodiment, the bonus symbols 200 may include one or more of the following symbols having one or more of the indicted features. These features are specifically applicable to the matching game described above, but may have applicability to a wide range of other games.
Bounce Slingos symbol: Enables 20 extra Slingos (linear matches) by using all 5 match combinations that utilize the site of the matrix.
Reel Nudge symbol: If the player spins a reel that does not trigger any number or Joker or Super Joker matches, after all other special items have occurred the game will automatically re-spin the reels/display a new set of base symbols 1 or more times and then process any new special items that occur.
Extra Jokers symbol: Adds an additional Joker position to the “special” category for a reel/base symbol position.
All Spins Free symbol: Players do not have to pay for the last 4 spins/base symbol displays of the game.
Multipliers symbol: Players who spin a multiplier will have all of the points earned for that spin multiplied. The effect occurs over ALL user initiated scoring events (match, Slingo, bounce Slingo, full card).
Extra Super Jokers symbol: Adds an additional Joker position to the “special” category for a reel/base symbol position.
Devil Protection symbol: When a Devil symbol appears in the base symbol positions/reels it is negated or always becomes a Cherub.
Extra Coins symbol: Gold coins worth 1,000 and Platinum coins worth 5,000 placed into reels/base symbol positions.
Cell Jokers symbol: Puts Jokers under certain numbers that appear after a match is made.
Power Shot symbol: Matches all numbers in positions around the particular number/position in a + shape in one match.
Instant Slingos symbol: Matches every position in the matrix (in every row and column), instantly making a Slingo combination win.
In other embodiments, the bonus symbols might have random effects.
As indicated, the bonus symbols might be applied to various bonus games. In the above-referenced embodiment, the bonus game or event might comprise a symbol matching game having features similar to the base game. A player might be given a certain number of attempts (such as base symbol spins) to match player symbols in a matrix to achieve one or more bonus event winning patterns or combinations. In one embodiment, a player might have to achieve a combination of matches in order to obtain any bonus winnings. In other embodiments, a player might be awarded winnings for individual matches.
As indicated, in a preferred embodiment of the invention the bonus symbols are collected during play of the base game. In the above-example, they may be randomly selected and displayed with the base symbols. However, they might be yielded in other manners. For example, bonus symbols might be awarded when a player receives a certain outcome of the base game. Relative to the above-referenced game, one or more bonus symbols might be hidden beneath game symbols in the matrix 20. If a player matches a game symbol having a hidden bonus symbol, the player may collect the hidden bonus symbol.
In a preferred embodiment, bonus symbol awarding events are presented as part of the base game. For example, at one or more times a bonus symbol awarding event might be initiated from the base game which allows a player to attempt to capture or select a bonus symbol. As one example, a bonus symbol collection event might comprise the display of five (5) suitcases, one or more of which hide a bonus symbol. The player might be permitted to select a single one of the suitcases to try and collect a bonus symbol. Such a feature might be initiated several times during the play of the base game, thus providing the player with multiple chances to collect bonus symbols during the play of the base game.
Of course, bonus symbols might be awarded or collected in other ways in association with the play of a base game. For example, bonus symbols might be randomly awarded. Bonus symbols might also be awarded for certain base game outcomes.
As indicated, the symbol collection feature of the invention may apply to other games. For example, a slot game might comprise the spinning of a plurality of reels bearing symbols. Certain symbols on the reels might, in certain combinations, form base game winning outcomes. Certain other symbols might be collectable bonus symbols. Such a bonus symbol might comprise a “wild” symbol. A player might collect “wild” bonus symbols during play of the base slot game. A player might be permitted to enter a bonus event, such as the play of a video poker hand, at one or more times. The player might be permitted to use their collected “wild symbols” to make one or more of the cards in their bonus video poker hand wild, thus permitting them to improve the probability of their forming a winning video poker hand.
This aspect of the invention has a number of benefits and advantages. First, the bonus symbol collection feature adds to the excitement of game play and entices a player to play base games to collect bonus symbols because the bonus symbols improve the likelihood of the player receiving a bonus award. The receipt of bonus symbols enhances the excitement of the game because the player anticipates the benefits that those symbols will yield the player in the play of the bonus game.
The aspect of collecting bonus symbols in the base game for use only in a bonus game or event is advantageous over game configurations involving only a base game. For example, some base games award a player a bonus win if the player plays for a certain period of time, receives a certain base game outcome or achieves certain levels of play. In such a configuration, however, the probability of the player being awarded a bonus award based upon sufficient levels of play and the odds of the player receiving the bonus are entirely fixed and calculated into the configuration of the base game (for example, if a player receives a bonus award for every 10 base games played and the average winning frequency of the base game is 50% and the average payout of a 5 credit wager base game is 4 credits, or 80%, paying a bonus award of 5 credits on the average of every 10 base games played simply increases the payout by a known fixed amount and the base payout rises to 85%). On the other hand, the bonus symbols of the present invention directly affect the probability of receiving a winning bonus outcome. Because the outcome of the bonus event can vary and is independent of the base game, the certainty or effect thereof to the base game is not fixed, thus resulting in much greater base and bonus game variability and excitement to the player.
Another embodiment of the invention comprises games and gaming machines having an option which permits a player to purchase potentially game-extending or win-improving features. Such features might comprise, for example, symbols or spins.
In a preferred embodiment, such an option only relates to a bonus game or event and not a base game or event. As one option, when a bonus game or event is initiated, a player may be permitted to purchase one or more game-extending or win-improving features.
One example of this option is illustrated in
As indicated above, this bonus event might comprise a symbol matching game wherein base symbols 322 (such as displayed by reels or the like) are matched to player symbols in a matrix 320. The player might be given a plurality of spins or turns in order to achieve as many matches as possible, in an attempt to achieve a particular bonus event winning outcome of matches. Each spin or turn may comprise the display of a random set of base symbols for comparison to the symbols in the matrix, in similar manner to the base game described above with reference to FIGS. 1 and 2A-2F.
As indicated above, in the play of such a bonus event, certain bonus symbols or other features preferably improve the probability of the player achieving a winning bonus event or a higher paying winning bonus event. In one embodiment, such symbols may be the bonus symbols 200 which the player collected during the play of a base game, as described in greater detail above.
As one aspect of the invention, however, the player may be provided with the option of purchasing one or more bonus symbols, as illustrated in
The particular purchase option may have various features and configurations. Preferably, the player is offered the option to purchase, such as for one or more credits or other monetary value, one or more bonus symbols. The number of bonus symbols which the player may purchase and their cost may vary.
If the game has the bonus symbol collection feature described above, purchased symbols may be added to those which were already collected. In this manner, a player may be provided with an opportunity to purchase bonus symbols that the player was unable to collect. The earlier collected and/or purchased bonus symbols 200 may be displayed in a bonus symbol display area 324, so as to indicate to a player those bonus symbols 200 which are available. As the bonus symbols 200 are utilized, they may be removed from that area 324.
In a preferred embodiment, if the game has the bonus symbol collection feature such as that described above, those bonus symbols are different from those which may be purchased. For example, a player may be permitted to collect one or more or all of a first set of up to 5 bonus symbols during the play of the base game. A player may then be permitted to purchase one or more or all of up to 3 bonus symbols before or during the bonus event, which 3 symbols are entirely different than those which may be collected during play of the base game. In this manner, a player is incentivized to try and collect as many of the set of bonus symbols from the base game as possible. At the same time, the player knows that even if they are not entirely successful in that endeavor, they may still purchase other symbols before or during the bonus event, thus still improving their chance to win the bonus event. In addition, this configuration requires that a player still purchase bonus symbols before or during the bonus event in order to have the maximum win improving opportunity (i.e. the player cannot collect all of the bonus symbols just during the base game).
The player may elect to purchase none, one or more of the bonus symbols. Once the player has made their selection, the bonus event preferably proceeds.
In one embodiment of the invention, a player may alternatively or in addition be provided the opportunity to purchase one or more additional spins or turns, thus potentially extending the game. For example, as indicated above, a bonus event might provide a base number of 16 turns or spins. If after those 16 turns or spins the player has not yet received a bonus winning outcome, the player might be provided the option to extend the bonus event by purchasing one or more additional spins or turns.
Preferably, the player must once again pay for the one or more game-extending spins or turns. The price of each turn or spin may be the same or the prices might vary.
In one embodiment, this option may be offered a single time, or it might be offered multiple times.
It will be appreciated that the type of features which may be purchased may vary. For example, a player might be permitted to purchase spins (such as reels spins or game symbol spins), reel nudges, wild or special symbols (such as those described above), or other features. Preferably, however, those one or more features have the potential to extend the bonus game or improve the probability of a player winning the bonus game. It will be appreciated that the type of bonus symbols (such as their effect) may vary, such as depending upon the bonus game. For example, if the bonus game is a reel-type game, the bonus symbols might include reel spins or nudges. If the bonus game is a poker game, the bonus symbols might include particular cards, wild cards, free draws or the like.
A particular advantage of this aspect of the invention is that the features relate only to a bonus game, and thus only affect the probability of the player achieving a bonus payout. For example, in a base slot game if a player were permitted to purchase additional spins, such could result not only in a base game win but such a win might trigger other types of events, such as a bonus award. Such a configuration could result in players always purchasing such a feature because such would be at least as beneficial as simply replaying the base game. Thus, such a feature might then not be viable. On the other hand, in accordance with the present invention the maximum bonus win amount is known. Thus, by offering players a greater chance to win the bonus win, players will at most win the bonus event every time. This bonus payout probability can be factored into the base game, such as the base game payout or the bonus event probability, so as to compensate for the potential higher frequency of bonus game payout.
While games of the invention may be played as wager-based games, it is possible for the games to be played as amusement games. In some cases, such games may still require that a player provide payment to play the game (though no monies may be awarded as prizes). In other embodiments, however, a player may not be required to make any payment or place any wager.
Aspects of the invention may be implemented via one or more gaming machines 120, such as illustrated in
In one embodiment, the gaming machine 120 is configured as a “video” type gaming machine, the machine including at least one display 124 for displaying game information to a player. The gaming machine 120 may include other means for providing information to a player. For example, speakers (not shown) or other devices may be provided for generating sound associated with the game. The gaming machine 120 may also include lights, printed instructions and other displays/display devices.
In one embodiment, a player must make payment in order to be entitled to play the game. Preferably, the game is presented as a wagering type game, and a player must place a bet or wager in order to play the game for the opportunity to receive winnings. Preferably, if the player is a winner of the game, the player is provided an award, such as a monetary payout (such as coins), credits representing monetary value, points or tangible prizes. As illustrated, the gaming machine 120 may include a bill validator/acceptor 126 for accepting paper currency and a coin acceptor 128 for accepting coins. Other means of payment, such as a credit card reader, may be provided. An award of winnings in the form of coins may be paid to the player via a coin tray 130.
Preferably, the gaming machine 120 includes means for a player to provide input. In one embodiment, this means comprises one or more buttons. For example, a “spin” button 132 may be provided for permitting a player to start a game. One or more wager buttons 134 may be provided for a player to select the amount to bet on a particular game. Other means of input may be provided, such as a touch-screen display and other devices now known or later developed.
A game controller (not shown) is provided for controlling the various devices of the gaming machine and for providing game information. For example, the game controller may be arranged to generate video and audio data for presentation by the display and speakers of the gaming machine 120. The game controller may be arranged to detect a signal from the coin acceptor indicating the receipt of coins or from the bill validator regarding accepted bills and for registering credits corresponding to those inputs, for subtracting credits for wagers placed by a player, and for causing a coin delivery mechanism to deliver coins from a coin hopper to the coin tray 130 for payment of winnings and/or return to a player of unwagered credits. Preferably, the one or more player input devices provide an output to the gaming controller for use in play of the game. For example, in response to a “bet one” input by a player, the gaming controller is preferably transmitted a signal which causes the gaming controller to initiate presentation of the game.
The gaming machine may include one or more random number generators for generating random game events and results. As indicated above, such a random number generator might be utilized to generate the game symbols for the positions of a matrix, be utilized to generate the base symbols, and be utilized to select award values for each symbol position, among other things.
It will be appreciated that the gaming machine 120 may have a variety of configurations, and that the gaming machine 120 illustrated and described above is but an example of a device for implementing the game of the present invention. For example, in one or more embodiments, the gaming machine 120 may be associated with a network and receive game information remotely and may transmit information, such as payout and game play information, to a remote location. For example, a remote master controller may generate game information which is transmitted over a communication link to the gaming machine 120. That information may be utilized by a local controller or processor to present the game, such as by displaying game play data or information.
As indicated, in one embodiment, game information is displayed by a video display 124 to a player. That display may be of a variety of types, including CRT, LCD, plasma and others. The gaming machine 120 may also include more than one video display.
In another embodiment, the gaming machine 120 may include one or more physical reels capable of displaying symbols. In such a configuration, means are provided for rotating the physical reels. In one or more embodiments, the means may comprise a mechanical linkage associated with a spin arm, with movement of the spin arm (a “pull”) by a user causing the reels to spin. In such an arrangement, the reels are generally allowed to free-wheel and then stop. In another embodiment, electronically controlled mechanisms are arranged to rotate and stop each reel. Such mechanisms are well known to those of skill in the art. In this arrangement, actuation of the spin arm or depression a spin button causes a controller (not shown) to signal the activation of the spin mechanism associated with one or more of the reels. Preferably, the controller is arranged to either turn off the signal to the device(s) effecting the rotation of each or all of the reels or generates a signal for activating a braking device, whereby the reels are stopped. As is well known, the combinations of reel positions and their odds of hitting are associated with the controller, and the controller is arranged to stop the reels in a position displaying a combination of indicia as determined by the controller based on the combinations and odds. The principal of such an arrangement is described in U.S. Pat. No. 4,448,419 to Telnaes, which is incorporated herein by reference. For example, the base symbols might be associated with spinning reels. Sets of base symbols might be generated by spinning those reels.
The gaming machine 120 may have other configurations, including other features. For example, the gaming machine 120 may include a player tracking device, such as a card reader 138 and associated keypad 140. Such player tracking devices are well known and may permit the game operator to track play of players of the gaming machine. The tracked play may be utilized to offer player bonuses or awards.
In one embodiment, the gaming machine 120 may be configured to dispense media, such as printed paper tickets, which have associated value. For example, winnings or unused credits may be returned to the player via a printed ticket having value or associated value. In one embodiment, the gaming machine 120 might also be configured to accept such media for providing credit for game play. Such systems are well known and thus not described in detail herein.
As indicated, in a preferred embodiment, the games of the invention are played as wagering type games in which a player must place a wager in order to play the game for an opportunity of winnings. However, in other embodiments, the games may be played for fun or prizes. In such event, the player may be permitted to play the game for free or may be required to make payment to play the game.
As indicated above, a player may provide value to the gaming machine 120 or machine operator in a number of ways, including with coins or bills. The player might also be permitted to provide value remotely. Value provided to the gaming machine 120 may be represented as credits. Each credit may have an associated monetary value.
The gaming system might include additional elements. As indicated above, the game may implement various progressive jackpots. In one embodiment, a plurality of gaming machines may be linked to one or more progressive servers. These servers may receive wager information from the gaming machines for use in managing the jackpots (including incrementing the jackpots to larger values). The progressive servers may also monitor game results for potential progressive jackpot wins. In the event of a win, the progressive servers may award a jackpot win to a player and may reset the progressive jackpot for that win back to a pre-set value.
The gaming machines and other components of a gaming system of the invention may communicate in various manners. For example, the various components of the gaming system might communicate via wired or wireless links or combinations thereof.
In one embodiment, a gaming machine of the invention may be particularly configured to present the game(s) of the invention. In other embodiments, the game(s) may be presented on a gaming machine which is configured to present a variety of different games.
In one embodiment, the gaming machine is configured to present a game of the invention via game instructions. Such instructions may comprise machine readable code. For example, game code or software may be stored in a memory of the gaming machine and be executed by the controller thereof to effectuate the various steps of the game, including the generation and display of game information. Of course, the gaming machine might also have a controller having such instructions embedded therein.
It is also possible for the gaming machine 120 to comprise a desk-top computer, a lap-top computer or even a mobile device such as a hand-held or mobile unit. For example, a game of the invention might be presented via a mobile phone or at a personal computer. In such a configuration, the processor of the computer may execute code which presents game information via a display associated with the computer. A player might provide input via a touch screen, computer mouse or keyboard. A player might place a wager by providing credit card information to provide one or more credits and by then using an input to place a wager of those credits. In another embodiment, some or all of the game information might be generated remotely, such as at a remote game server, and be transmitted over a communication link to the player's computer.
In one embodiment, the game of the invention may be implemented as an “on-line” game. Such a game may be presented as a wager-based game or an amusement game. Such a game may be presented by a player utilizing their computer to access a game server via the Internet. The game server may transmit game code for execution by the user's computer for presenting the game.
It will be understood that the above described arrangements of apparatus and the method there from are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
