DETERMINATION OF GAME RESULT USING RANDOM OVERALL OUTCOME
Embodiments of the present invention are directed to determining a game result on a gaming device by randomly selecting the overall outcome of each game event on the gaming device. Unlike conventional gaming devices that analyze a plurality of random selections, embodiments of the present concept select the overall outcome of a game event a plurality of possible game outcomes. By utilizing the selection of an overall outcome, it may be easier to direct certain outcomes on a gaming device in response to triggering events and may provide a more flexible design platform in which to design the play of the gaming device.
This disclosure relates generally to gaming devices, and more particularly to gaming devices configured to determine game results by randomly selecting an overall game outcome.
BACKGROUNDTypically game results of gaming devices are determined by analyzing a series of random selections associated with the game. For example, in spinning reel slot machines, a reel-stop position for each reel is randomly selected. Once each random selection is made, the combination of randomly selected reel-stop positions is analyzed to determine if the combination of symbols associated with the reel-stop positions results in an award for the player. Similarly, in video poker or blackjack random cards are selected and then analyzed to see if the combination of randomly selected cards results in an award for the player.
The process of making a series of random selections and then analyzing the results of these selections imposes several limitations both in the capabilities of gaming devices and the design of the games on the gaming devices. For the game devices themselves, the above process requires multiple random numbers to be used each time a game is played and limits the flexibility of the machine in awarding specific outcomes resulting from other triggering events. In the slot machine example, a random number must be used for each reel to determine which reel stop or stops are to be displayed on a game outcome display. For demonstration purposes, certain reel stop combinations can programmed into the game logic to illustrate a particular bonus or jackpot win. However, during actual game play in which a player is wagering on the outcome of the gaming device, the game outcomes are often limited by the combination of randomly selected reel stops; thereby limiting the ability to dictate certain symbol combinations displayed on the reels in response to triggering events. This dictation of certain symbol combinations may be desirable to alter the payback percentage of the gaming devices, provide bonuses to the players, or guarantee that certain gaming events happen within a given time frame.
In addition, during the design of a gaming device having spinning reels, it is often difficult to obtain multiple exact payback percentages for a given gaming machine because of the limitations involved in assigning values to each reel stop and/or setting up reel strips. For mechanical spinning reel games, reel strips typically include twenty-two physical reel stops. Game designers may assign a certain number of virtual stops or paytable stops to each of these physical stops to allow large prizes to be given away less than once every 10,648 spins. This allocation of virtual stops can be challenging when attempting to meet multiple precise payback percentage paytables as well as difficult in setting hit frequencies of winning symbol combinations. For multi-line video slot games, the complexity of determining the number of each symbol on the reels as well as laying out the symbols on a reel strip can be complex and very time consuming.

The gaming device 10 includes a cabinet 15 housing components to operate the gaming device 10. The cabinet 15 may include a gaming display 20, a base portion 13, a top box 18, and a player interface panel 30. The gaming display 20 may include mechanical spinning reels (
The base portion 13 may include a lighted panel 14, a coin return (not shown), and a gaming handle 12 operable on a partially rotating pivot joint 11. The game handle 12 is traditionally included on mechanical spinning-reel games, where the handle may be pulled toward a player to initiate the spinning of reels 22 after placement of a wager. The top box 18 may include a lighted panel 17, a video display (such as an LCD monitor), a mechanical bonus device (not shown), and a candle light indicator 19. The player interface panel 30 may include various devices so that a player can interact with the gaming device 10.
The player interface panel 30 may include one or more game buttons 32 that can be actuated by the player to cause the gaming device 10 to perform a specific action. For example, some of the game buttons 32 may cause the gaming device 10 to bet a credit to be wagered during the next game, change the number of lines being played on a multi-line game, cash out the credits remaining on the gaming device (as indicated on the credit meter 27), or request assistance from casino personnel, such as by lighting the candle 19. In addition, the player interface panel 30 may include one or more game actuating buttons 33. The game actuating buttons 33 may initiate a game with a pre-specified amount of credits. On some gaming devices 10 a “Max Bet” game actuating button 33 may be included that places the maximum credit wager on a game and initiates the game. The player interface panel 30 may further include a bill acceptor 37 and a ticket printer 38. The bill acceptor 37 may accept and validate paper money or previously printed tickets with a credit balance. The ticket printer 38 may print out tickets reflecting the balance of the credits that remain on the gaming device 10 when a player cashes out by pressing one of the game buttons 32 programmed to cause a ‘cashout.’ These tickets may be inserted into other gaming machines or redeemed at a cashier station or kiosk for cash.
The gaming device 10 may also include one or more speakers 26 to transmit auditory information or sounds to the player. The auditory information may include specific sounds associated with particular events that occur during game play on the gaming device 10. For example, a particularly festive sound may be played during a large win or when a bonus is triggered. The speakers 26 may also transmit “attract” sounds to entice nearby players when the game is not currently being played.
The gaming device 10 may further include a secondary display 25. This secondary display 25 may be a vacuum fluorescent display (VFD), a liquid crystal display (LCD), a cathode ray tube (CRT), a plasma screen, or the like. The secondary display 25 may show any combination of primary game information and ancillary information to the player. For example, the secondary display 25 may show player tracking information, secondary bonus information, advertisements, or player selectable game options.
The gaming device 10 may include a separate information window (not shown) dedicated to supplying any combination of information related to primary game play, secondary bonus information, player tracking information, secondary bonus information, advertisements or player selectable game options. This window may be fixed in size and location or may have its size and location vary temporally as communication needs change. One example of such a resizable window is International Game Technology's “service window.” Another example is Las Vegas Gaming Incorporated's retrofit technology which allows information to be placed over areas of the game or the secondary display screen at various times and in various situations.
The gaming device 10 includes a microprocessor 40 that controls operation of the gaming device 10. If the gaming device 10 is a standalone gaming device, the microprocessor 40 may control virtually all of the operations of the gaming devices and attached equipment, such as operating game logic stored in memory (not shown) as firmware, controlling the display 20 to represent the outcome of a game, communicating with the other peripheral devices (such as the bill acceptor 37), and orchestrating the lighting and sound emanating from the gaming device 10. In other embodiments where the gaming device 10 is coupled to a network 50, as described below, the microprocessor 40 may have different tasks depending on the setup and function of the gaming device. For example, the microprocessor 40 may be responsible for running the base game of the gaming device and executing instructions received over the network 50 from a bonus server or player tracking server. In a server-based gaming setup, the microprocessor 40 may act as a terminal to execute instructions from a remote server that is running game play on the gaming device.
The microprocessor 40 may be coupled to a machine communication interface (MCI) 42 that connects the gaming device 10 to a gaming network 50. The MCI 42 may be coupled to the microprocessor 40 through a serial connection, a parallel connection, an optical connection, or in some cases a wireless connection. The gaming device 10 may include memory 41 (MEM), such as a random access memory (RAM), coupled to the microprocessor 40 and which can be used to store gaming information, such as storing total coin-in statistics about a present or past gaming session, which can be communicated to a remote server or database through the MCI 42. The MCI 42 may also facilitate communication between the network 50 and the secondary display 25 or a player tracking unit 45 housed in the gaming cabinet 15.
The player tracking unit 45 may include an identification device 46 and one or more buttons 47 associated with the player tracking unit 45. The identification device 46 serves to identify a player, by, for example, reading a player-tracking device, such as a player tracking card that is issued by the casino to individual players who choose to have such a card. The identification device 46 may instead, or additionally, identify players through other methods. Player tracking systems using player tracking cards and card readers 46 are known in the art. Briefly summarizing such a system, a player registers with the casino prior to commencing gaming. The casino issues a unique player-tracking card to the player and opens a corresponding player account that is stored on a server or host computer, described below with reference to
To induce the player to use the card and be an identified player, the casino may award each player points proportional to the money or credits wagered by the player. Players typically accrue points at a rate related to the amount wagered, although other factors may cause the casino to award the player various amounts. The points may be displayed on the secondary display 25 or using other methods. In conventional player tracking systems, the player may take his or her card to a special desk in the casino where a casino employee scans the card to determine how many accrued points are in the player's account. The player may redeem points for selected merchandise, meals in casino restaurants, or the like, which each have assigned point values. In some player tracking systems, the player may use the secondary display 25 to access their player tracking account, such as to check a total number of points, redeem points for various services, make changes to their account, or download promotional credits to the gaming device 10. In other embodiments, the identification device 46 may read other identifying cards (such as driver licenses, credit cards, etc.) to identify a player and match them to a corresponding player tracking account. Although
During typical play on a gaming device 10, a player plays a game by placing a wager and then initiating a gaming session. The player may initially insert monetary bills or previously printed tickets with a credit value into the bill acceptor 37. The player may also put coins into a coin acceptor (not shown) or a credit, debit or casino account card into a card reader/authorizer (not shown). One of skill in the art will readily see that this invention is useful with all gambling devices, regardless of the manner in which wager value-input is accomplished.
The credit meter 27 displays the numeric credit value of the money inserted dependent on the denomination of the gaming device 10. That is, if the gaming device 10 is a nickel slot machine and a $20 bill inserted into the bill acceptor 37, the credit meter will reflect 400 credits or one credit for each nickel of the inserted twenty dollars. For gaming devices 10 that support multiple denominations, the credit meter 27 will reflect the amount of credits relative to the denomination selected. Thus, in the above example, if a penny denomination is selected after the $20 is inserted the credit meter will change from 400 credits to 2000 credits.
A wager may be placed by pushing one or more of the game buttons 32, which may be reflected on the bet meter 28. That is, the player can generally depress a “bet one” button (one of the buttons on the player interface panel 30, such as 32), which transfers one credit from the credit meter 27 to the bet meter 28. Each time the button 32 is depressed an additional single credit transfers to the bet meter 28 up to a maximum bet that can be placed on a single play of the electronic gaming device 10. The gaming session may be initiated by pulling the gaming handle 12 or depressing the spin button 33. On some gaming devices 10, a “max bet” button (another one of the buttons 32 on the player interface panel 30) may be depressed to wager the maximum number of credits supported by the gaming device 10 and initiate a gaming session.
If the gaming session does not result in any winning combination, the process of placing a wager may be repeated by the player. Alternatively, the player may cash out any remaining credits on the credit meter 27 by depressing the “cash-out” button (another button 32 on the player interface panel 30), which causes the credits on the credit meter 27 to be paid out in the form of a ticket through the ticket printer 38, or may be paid out in the form of returning coins from a coin hopper (not shown) to a coin return tray.
If instead a winning combination (win) appears on the display 20, the award corresponding to the winning combination is immediately applied to the credit meter 27. For example, if the gaming device 10 is a slot machine, a winning combination of symbols 23 may land on a played payline on reels 22. If any bonus games are initiated, the gaming device 10 may enter into a bonus mode or simply award the player with a bonus amount of credits that are applied to the credit meter 27.
Referring to
During game play, the spinning reels 22A may be controlled by stepper motors (not shown) under the direction of the microprocessor 40 (
A gaming session on a spinning reel slot machine 10A typically includes the player pressing the “bet-one” button (one of the game buttons 32A) to wager a desired number of credits followed by pulling the gaming handle 12 (

Because the virtual spinning reels 22B, by virtue of being computer implemented, can have almost any number of stops on a reel strip, it is much easier to have a greater variety of displayed outcomes as compared to spinning-reel slot machines 10A (
With the possible increases in reel 22B numbers and configurations over the mechanical gaming device 10A, video gaming devices 10B often have multiple paylines 24 that may be played. By having more paylines 24 available to play, the player may be more likely to have a winning combination when the reels 22B stop and the gaming session ends. However, since the player typically must wager at least a minimum number of credits to enable each payline 24 to be eligible for winning, the overall odds of winning are not much different, if at all, than if the player is wagering only on a single payline. For example, in a five line game, the player may bet one credit per payline 24 and be eligible for winning symbol combinations that appear on any of the five played paylines 24. This gives a total of five credits wagered and five possible winning paylines 24. If, on the other hand, the player only wagers one credit on one payline 24, but plays five gaming sessions, the odds of winning would be identical as above: five credits wagered and five possible winning paylines 24.
Because the video display 20B can easily modify the image output by the video display 20B, bonuses, such as second screen bonuses are relatively easy to award on the video slot game 10B. That is, if a bonus is triggered during game play, the video display 20B may simply store the resulting screen shot in memory and display a bonus sequence on the video display 20B. After the bonus sequence is completed, the video display 20B may then retrieve the previous screen shot and information from memory, and re-display that image.
Also, as mentioned above, the video display 20B may allow various other game information 21B to be displayed. For example, as shown in
Even with the improved flexibility afforded by the video display 20B, several physical buttons 32B and 33B are usually provided on video slot machines 10B. These buttons may include game buttons 32B that allow a player to choose the number of paylines 24 he or she would like to play and the number of credits wagered on each payline 24. In addition, a max bet button (one of the game buttons 32B) allows a player to place a maximum credit wager on the maximum number of available paylines 24 and initiate a gaming session. A repeat bet or spin button 33B may also be used to initiate each gaming session when the max bet button is not used.
Referring to
The player selectable soft buttons 29C appearing on the screen respectively correspond to each card on the video display 20C. These soft buttons 29C allow players to select specific cards on the video display 20C such that the card corresponding to the selected soft button is “held” before the draw. Typically, video poker machines 10C also include physical game buttons 32C that correspond to the cards in the hand and may be selected to hold a corresponding card. A deal/draw button 33C may also be included to initiate a gaming session after credits have been wagered (with a bet button 32C, for example) and to draw any cards not held after the first hand is displayed.

Gaming devices 71 coupled over an optical line 64 may be remote gaming devices in a different location or casino. The optical line 64 may be coupled to the gaming network 50 through an electronic to optical signal converter 63 and may be coupled to the gaming devices 71 through an optical to electronic signal converter 65. The banks of gaming devices 70 coupled to the network 50 may be coupled through a bank controller 60 for compatibility purposes, for local organization and control, or for signal buffering purposes. The network 50 may include serial or parallel signal transmission lines and carry data in accordance with data transfer protocols such as Ethernet transmission lines, Rs-232 lines, firewire lines, USB lines, or other communication protocols. Although not shown in
As mentioned above, each gaming device 70-75 may have an individual processor 40 (
Thus, in some embodiments, the network 50, server 80, and database 90 may be dedicated to communications regarding specific game or tournament play. In other embodiments, however, the network 50, server 80, and database 90 may be part of a player tracking network. For player tracking capabilities, when a player inserts a player tracking card in the card reader 46 (
The various systems described with reference to
Embodiments of this concept are directed to determining game outcomes based on the outcomes themselves instead of making a series of random selections and analyzing those selections to determine the game outcome. For example, in a spinning reel slot machine, the outcome of three bar-type symbols (Any Bars) may be directly selected from a list or table of possible outcomes instead of determining that the first reel stopped on a single bar symbol, the second reel stopped on a triple bar symbol, and the third reel stopped on a single bar symbol, where a further analysis must be done to determine that these reel stops result in an any bar award.
While the direct selection of a game outcome may require slightly fewer microseconds for a processor to determine the game outcome, this advantage may be relatively small in traditional game play since the speed and capacity of the processors used in recent game devices is usually adequate to perform either method in well less than a second. However, embodiments of the present concept allow for much more flexible design of the gaming device and may be easily modifiable by a casino operator or even dynamically during game play to alter the paytable, and hence the feel, of the game. For example, as discussed above, a game designer is typically tasked with determining how many physical and/or virtual symbols to place on each reel and then create a reel strip that conforms to those symbol parameters. For a physical 3-reel slot machine, there is typically not much flexibility in minutely altering payback percentages because the addition or subtraction of a single virtual stop generally has a significant affect on the overall payback percentage of the gaming device. For a 5-reel video slot machine, each symbol that is added to a reel generally needs to be fit into that reel strip. With reel lengths that often times are greater than seventy or eighty symbols, it can take a lot of time and talent to arrange all of the symbols on each of the reel strips.
Additionally, in either type of gaming device, it is nearly impossible to alter or modify a paytable during a gaming session to change the game performance between gaming events because the addition or subtraction of a symbol necessarily requires the creation of new reel strips. In contrast, since embodiments of this concept select game outcomes from a list or table, a modification of this table or list during game play can easily alter the paytable and game characteristics without the need to modify the reel strips or other aspects of the game device. These advantages and others will be discussed below in the following examples and embodiments of this concept. Although spinning reel gaming devices are often discussed for purposes of providing examples, embodiments of this concept can be used with any type of gaming device.
Referring to the paytable shown in
The “Paytable Weight” column provides a number range for each of the outcomes that determines how often that outcome occurs. The “Hit Frequency” column reflects what percentage of spins will result in a corresponding wager. The hit frequency is simply determined by dividing the associated paytable weight by the total of all of the paytable weights, which in this example is “2246.” For example, the single bar outcome of “BAR BAR BAR” has an associated Paytable weight of “50,” and a hit frequency of 2.23%. This means that a player is expected to hit a “BAR BAR BAR” outcome about every 45 games. The paytable weight is an important element in determining hit frequency, payback percentage, and volatility of the game. When developing a game paytable, a game designer can alter the types of winning outcomes, the pay of the winning outcomes, and the weight of the paytable weight of an outcome to produce the play characteristics of the gaming device. However, once the determination is made about what symbol combinations will be winning outcomes and what award each of those winning outcomes should pay, the main variable in altering the play characteristics of the gaming device is the paytable weight associated with each outcome. Unlike traditional games, the games associated with embodiments of this concept allow the game designer to control the hit frequency of specific game outcomes by manipulating the paytable weights associated with those game outcomes. Additionally, the overall hit frequency of a gaming device and the volatility of the gaming device can be quickly shaped using the paytable weights. In the example paytable illustrated in
The “Contribution” column is achieved by multiplying the value in the “Pay” column with the value in the “Hit Freq” column. This contribution relates to the relative or normalized weight each outcome has on the payback percentage of the game. The sum of these contributions results in the overall payback percentage of the game, which in this example is 97.95%. The hold percentage of a gaming device is simply 100% minus the payback percentage. Thus, in this example, the hold percentage of a gaming device using this paytable would be 2.05%. The contribution column provides a method of determining what portion of a paytable is directed to a particular outcome.
Referring to the reel strips illustrated in
In this embodiment, operation of the gaming device includes obtaining a random number or indicator once the player has pulled a game handle or pressed a game initiating button, and normalizing this random number to match one of the ranges associated with the paytable weights for each outcome. These ranges may be determined by using the paytable weights from the paytable illustrated in
Although the embodiment discussed above selects an outcome using a randomly obtained number or indicator, other outcome selection methods or processes may be used in different embodiments. For instance, certain gaming events on the gaming device may trigger the selection of a particular gaming outcome or type of gaming outcome. In one example, a gaming device may be configured to provide a “CH CH CH” award if a winning outcome has not been reached in twenty consecutive games. In this example, the selection of the “CH CH CH” outcome would be the result of a device instruction rather than a result associated with a randomly obtained indicator. Many other circumstances exist in which a particular outcome or a type of outcome, such as a winning outcome, may be selected or determined without an element of randomness.
Once an outcome has been determined, the gaming device selects the reel stops corresponding to the outcome to display to the player. The reels are then spun and the selected reel stops are displayed on the payline. As noted above, the reel strips will often include multiple instances of a symbol. Hence, the actual determination of which symbol to display may involve a selection process. This selection process may include a random selection, an alternating selection, or another type of selection process to determine which of the reel stops associated with a particular symbol to display. For a losing outcome, the gaming device may again use a selection process to select a losing outcome to display. There are many variations of how to select a proper winning outcome and how to select a losing outcome. Some of these variations are discussed in detail below with respect to
One advantage of this method of determining a game outcome is that paytables can be easily changed between game events. For example, it may be desirable to alter the characteristics of a paytable for one or more games in response to a triggering event. For instance, a player may experience fifteen consecutive losing outcomes, which triggers a change in the paytable for next two games. This change may include temporarily altering the paytable weights associated with each outcome. In one instance, the paytable weight for the generic losing outcome may be reduced to 1000 and 800 extra paytable “weight points” may be added to the cherry, any bar, and single bar outcomes, thereby giving the player a better than 50% chance of having a winning outcome for the next to games. Infinite different variations exist for many different triggering conditions and alterations of the paytable. However, unlike traditional method of determining a game outcome, embodiments of the present conceptual method provide a simple way to alter the paytable, chance game characteristics, or emphasize certain results without completely changing how a gaming device operates or significantly modifying its virtual and/or physical reel strips.
The above description has focuses on a spinning reel gaming device having a single payline. However, other embodiments of this concept are adapted to work with multi-line gaming devices. For less complex multi-line gaming device a similar calculation method as described above can be used.
Referring to
Three operational examples will now be described with reference to
For the purposes of this first example, a player is playing a single payline gaming device or only playing one line of a multi-line gaming device. After a wager is received and the game initiated, a random number is obtained that corresponds to the outcome of three cherry symbols (“CH CH CH”). As described above, this determination of the game outcome may be done immediately after an input to initiate a game is received. Thus, although the game outcome may be determined at this time, the player is not aware of the outcome as it has not yet been displayed. The reels may also be triggered to begin spinning in response to the activation of the game initiating player input.
Because multiple cherry symbols (CH) exist on each of the reel strips, a game outcome display needs to be determined. Cherry symbols are included at reel stops 2 and 16 on the first reel strip, at reel stops 12 and 22 on the second reel strip, and at reel stops 14 and 22 on the third reel strip. Thus, the following combination of reel stops shown in table A may be used as a game outcome display to show the determined game outcome of three cherry symbols.
In some embodiments, these combinations may be predetermined and coded into the memory of the game device so that they may be quickly accessed and used when an associated outcome is determined to be a game outcome. The game processor may randomly choose one of these eight possible game outcome displays as the game outcome display to show, or the game processor may cycle through each of the possible game outcome displays when the three cherry symbol outcome is determined to be the game outcome. In other embodiments, the game processor may randomly select one of the corresponding reel stops for each reel. Thus, the game processor may select between stops 2 and 16 for reel 1, between stops 12 and 22 for reel 2, and between stops 14 and 22 on reel 3. Here instead of calculating out all of the possible outcome combinations, these embodiments only require that the identity of each symbol on the reel strip be recorded in the gaming code and identifiable to match a symbol needed for a determined game outcome. Alternate methods of determining the game display outcome are also possible.
Once a game outcome display is selected, the game can stop each of the reels on the selected reel stops to show the determined game outcome display.
For the purposes of this second example, a player is playing all three lines of a multi-line gaming device illustrated in
For purposes of Example 2, after a wager is received and the game initiated, a first random number corresponding to the first payline is obtained that is associated with the outcome of three cherry symbols (“CH CH CH”), a second random number is then obtained that is associated with the generic losing outcome, and a third random number is obtained that is also associated with the outcome of three cherry symbols (“CH CH CH”). Obviously, it would be impossible to have the have the physical spinning reels display three cherries on the first payline and the third payline at the same time. Since the gaming device awards the highest paying of the outcomes in situations where multiple outcomes are present, the game would indicate that a winning outcome of three cherries is to be displayed on the first payline. Note that since the outcome of three cherries received on the third payline was not associated with an award value greater than the outcome for payline 1, it does not replace the outcome for the first payline. A display technique similar to one of the game outcome display techniques described above in Example 1 may then be used to display the game outcome of three cherries as shown in
For the purposes of this third example, a player is again playing all three lines of a multi-line gaming device illustrated in
Next the game device would use one of the above-described methods of displaying the winning outcome of three bars on the third payline. In this instance, the reel stop positions of 4, 14, and 16 are respectively chosen as being displayed on the third payline. This displayed outcome is shown in
Although these examples are used to illustrate some basic embodiments of the present concept, many other variations and alternatives exist in implementing principles of this concept.
Referring to
The outcome for the game is then determined from the outcome selecting indicator in process (216). Because most game devices utilize many possible outcomes, a few of which are winning outcomes, the outcome selecting indicator may be preferably used to determine if the outcome is a losing outcome or one of a plurality of winning outcomes. That is, as described above with respect to
After a game outcome has been determined in process (216), display characteristics of the game outcome are determined in process (218). This process involves determining how to display the game outcome determined in process (216). If a winning outcome is determined as the game outcome in process (216), the display characteristic determination may include identifying reel stop numbers or card values corresponding to the winning outcome and selecting which of the identified reel stop numbers or card values to display as the game outcome. This process is more fully discussed below with respect to
The game event is then displayed to the player in process (220). The display of the game event may have begun upon receiving a wager (210) or upon initiation of the game (212), but does not conclude until the game outcome display has been determined in process (218). For example, in a spinning reel gaming device, the reels may have begun to spin prior to the determination of the game outcome display, but the reels will not stop until it is determined where they are going to stop so that they properly show the determined game outcome. In another example, the display of a game event for a video poker gaming device may include displaying a dealt hand, receiving one or more player inputs to hold and draw cards, and displaying a final poker hand.
At the conclusion of the game event, the game outcome will be displayed to the player in process (222). Depending on the type of gaming device being played, the display of the game outcome may include the stopped positions of game reels, a final poker hand, a complete keno number reveal, a blackjack dealer's hand, etc. If the game outcome is associated with a bonus, play of the gaming device may transfer to a bonus mode to allow the player to play a bonus and/or receive a bonus award. If the game outcome is a winning game outcome, the award associated with the winning outcome and any other displayed winning combination is paid in process (224).
Referring to
After a winning outcome has been determined, the reel stop positions associated with the symbols of the winning outcome are identified in process (232). For example, in the three reel slot machine example discussed with reference to
Once the reel stop positions (or other winning indicia) associated with the game outcome have been identified (232), the gaming device selects among the identified reel stop positions to determine the reel stops for the game outcome display. In the three reel slot example, the gaming device may select reel stops 8, 18, and 18 as the reel stops of the double bars to display as the game outcome. In the video poker example, the gaming device may select the 2, 5, 8, Jack, and Ace of hearts to display as the game outcome. This selection process may include randomly selecting among the identified reel stop positions or cards in some embodiments. Alternatively, the selection process may sequentially choose between the reel stops and cards, or use another selection technique.
In process 236, the gaming device determines whether there are any further reels (or cards) to determine for the displayed winning outcome. For example, if the three reel slot device selected the bonus (“X X BN”) as the winning outcome, the second reel stop of the third reel would be selected to display the winning outcome. However, since the win only requires a bonus symbol to land on the payline of the third reel for a bonus win, the outcomes displayed on the first two reels do not affect this winning outcome. In such a case, the gaming device would select two other reel stop positions for reels 1 and 2 to complete the game outcome display in process 238. In a five reel slot device, wins are typically given for three and four symbol combinations the fall on a payline from left to right. Hence, if a winning outcome was selected for a three symbol win on a five reel game, reel stops for the other two reels would be selected in process 238. In the above video poker example, after the five heart cards were selected, five other cards would be selected to complete the possible dealt and draw hands in process 238. These additional selections of process 238 may be made randomly or by another selection technique.
If there are extra reels or cards to determine, after these other reel stops or cards have been determined, the gaming device insures that these additional selections do not affect the game outcome in process (240). In the three reel example, it would make no difference which reel stops were selected for reels 1 and 2. However, in the five reel example where a three symbol winning outcome was selected, process (240) would insure that a fourth symbol matching the symbol of the winning outcome did not fall on the same payline for the fourth reel since this four symbol win would be significantly greater than the winning outcome that was determined by the in process (216) of
When it is determined that either no additional reels need to be determined or that the additional reels that have been determined do not affect the outcome, the determined game outcome is displayed to the player in process (242). For the spinning reel examples, the display of this outcome is described above. Further details of methods of displaying a video poker outcome are discussed below with respect to

After a losing outcome has been determined, the game device may determine whether the losing outcome is to be a near-miss outcome in process (252). Near-miss outcomes are outcomes that initially appear to be headed toward a large prize only to nearly miss the prize at the last moment. For instance, in the three-reel gaming device example described above, a near miss outcome may be a jackpot symbol landing on the payline for the first reel, a jackpot symbol landing on the payline for the second reel, and a blank adjacent to the a jackpot symbol landing on the payline for the third reel. Since the first reel stops first, followed by the second reel stopping, the player may become excited thinking they have a good chance at winning the jackpot award. When the third reel finally stops, they may be disappointed about not winning the jackpot, but they will typically be more excited about “nearly missing” the jackpot than had they received a losing outcome with three blank symbols even though neither result pays any credits.
A determination of whether a losing outcome is a near-miss outcome in process (252) may include a separate determination from the initial determination of the game outcome in process (216) of
If a near-miss outcome is selected in process (252), the actual near-miss outcome to be displayed is determined in process (258). If near-misses are included in the game paytable, this process (258) would include identifying which of the near-miss outcomes specified in the paytable was selected. If a separate list of near-miss outcomes is used, process (258) may include selecting, randomly or otherwise, one of the specified near-miss outcomes to display.
If the gaming device does not include a near-miss outcome option, or when it is determined that the losing outcome is not a near-miss outcome, the gaming device selects a game outcome to display in process (254). For a spinning reel gaming device, this process may include selecting reel stops for each of the reels. For a video poker gaming device, this process may include selecting cards to display. Since there are typically a very large number of possible losing outcomes, the selection process may randomly select reel stops or cards to display as the losing outcome. However, other selection methods may be employed to determine the reel stops or cards. After this selection has taken place, the gaming device determines whether the selected outcome is a losing outcome in process (256). That is, process (256) insures that a selected outcome to display is not associated with an award. If the selected outcome is determined to be associated with an award, the outcome selection in process (254) is repeated until a selected outcome is determined to be a losing outcome. After a losing outcome to display is determined, or a near-miss outcome is selected, the gaming device displays this outcome to the player in process (260).
As alluded to above with respect to

After determining a outcome for each payline, the gaming device determines if any winning outcomes have been stored in memory in process (320). If no winning outcomes have been determined, the gaming device selects a losing outcome in process (330). This selection process (330) may include the process steps of selecting a losing outcome discussed in
The winning outcome display determined in process (322) would then be displayed to the player in process (324) and prizes associated with this winning outcome would be awarded to the player in process (326). In some embodiments, the payline for which the winning outcome is associated with may be highlighted prior to the reels being spun so that the player focuses on the symbols landing on that payline. Winning combinations incidentally appearing on other paylines not associated with the highlighted payline would not be paid. If additional winning outcomes are stored in memory as determined in process (328), processes (322), (324), and (326) are repeated for each of these stored winning outcomes. In other embodiments, each winning outcome display may be determined (322) prior to displaying any of the outcomes (324) or awarding any prizes (326). Essentially, these embodiments would move process (328) up in flow 300 so it was between processes (322) and (324). This process may be exciting for a player because each spin of the gaming device results in a winning outcome. Thus, with each additional spin, the player may become more excited. In some embodiments, the stored winning outcomes may be displayed sequentially be payline number. Hence, a win on payline 2 would be displayed before a win on payline 5. In other embodiments, the stored winning outcomes may be rearranged so that the winning outcomes are displayed from smallest award amount to largest award amount. For example, if the award associated with the winning outcome on payline 2 is greater than the award amount associated with the winning outcome on payline 5, the winning outcome on payline 5 may be displayed first. These embodiments may build further excitement for a player as each additional spin will not only result in another win, but likely a larger win. Each iteration of displaying a winning outcome and providing an award to the player may be done without further player interaction.
In other embodiments, outcomes may be selected and displayed for each of the lines played. In these embodiments, loses may be only briefly displayed while wins are displayed for a longer period of time as described in co-pending U.S. patent application Ser. No. 12/204,633, filed Sep. 4, 2008, entitled GAMING DEVICE HAVING VARIABLE SPEED OF PLAY, the teachings of which are incorporated herein by reference.

If it is determined that a winning outcome has been stored in process (320), the gaming device selects a winning outcome to display in process (321) and confirms that this outcome display does not include a winning combination with an award value greater than the award value of the selected winning outcome in process (323). The reason for this confirmation process (323) is to prevent a relatively low winning award repeatedly bringing up a much larger jackpot award since this would significantly nullify the weighted values in the paytable. However, additional lower paying awards may be allowed to be paid as one of the benefits of playing multiple lines. Once a winning outcome display has been selected and confirmed, the winning outcome is displayed on the associated payline in process (324) and the award from the winning outcome and any other winning combinations appearing on other played paylines are paid to the player in process (326).
Referring to
In process (354), it is determined whether the selected outcome is a winning outcome. If it is a losing outcome, an outcome to display is determined in process (356) and it is confirmed that this outcome to display is a losing outcome and does not provide a winning combination on another played payline in process (358). Once the displayed outcome is determined to be a losing outcome, the losing outcome is displayed in process (360). Since it doesn't matter on which payline the losing outcome is displayed, the reel stops associated with the losing outcome may be displayed on a central payline, which is usually the first payline.
If process (354) determines that the selected outcome is a winning outcome, the gaming device selects among reel stop positions associated with the winning outcome to determine the reel stop positions to display in process (370). The gaming device then chooses which of the played lines to display the determined reel stops associated with the winning outcome in process (372). The selection of the payline to display the game outcome in process (372) may be a random selection, a sequential selection through the paylines, or another type of selection. Once the reel stops are known and the payline on which they will be displayed is known, the game device analyzes the other reel positions to determine if any of the other paylines include a winning combination in process (374). Unlike the example flow 305 illustrated in
The multi-line selection methods described above focus on gaming devices that may have fixed reel strips. That is, reel strips that correspond to each reel of the game device and do not change between games. However, for gaming devices that use individual reel strips for each symbol position on a gaming display (“super spin” games) or for gaming devices that use flexible reel strips, alternative multi-line techniques may be available. Super spin games and flexible reel strip games have the ability to select a symbol for every displayed symbol position on a gaming display. Thus, more detailed selection processes may be used in choosing the symbols to display on the screen. In one example, a multi-line game may select an outcome for each played line where the game locks in winning outcome symbol positions for paylines that are determined earlier. That is, if a player is playing a five line game (
In another example, a multi-line game may select a single award value and apportion this award value between multiple outcomes displayed on played paylines. That is, if an award value of 150 credits was selected, an outcome associated with a 100 credit award may be selected for payline 1, an outcome associated with a 40 credit award may be selected for payline 3, and an outcome associated with a 10 credit award may be selected for payline 5. In addition, other symbols may be selected for the symbol positions not involved in the selected outcomes that cause near-miss outcomes to appear on other played lines. This may give the player the feeling that they almost won additional credits.
As discussed above, this concept is not limited only to slot machine gaming devices. Rather, this outcome determination concept can be used with a variety of different gaming device types or themes. For example, this concept may be used with keno, video blackjack, video poker, etc.

If the selected outcome is not determined to be a winning outcome in process (414) (i.e., it is a determined to be a losing outcome), a group of dealt cards and possible draw cards are selected in process (420) and confirmed to result in a losing hand using the best strategy assumptions in process (425). For example, if the dealt hand includes 4H, 6S, 8D, 10C, and QD, the best strategy would be to hold the QD and draw four cards. Process (425) would ensure that that another Q or another winning combo did not exist in the next four draw cards. However, assume that the player held the 8D and the draw cards included 8S and 8H in the next four draw cards. The player would actually win here, even though a losing outcome was selected since the player was not using the best strategy assumed by the gaming device. Other embodiments may ensure that no win is possible when it is determined that the outcome is a losing outcome.
If the selected outcome is determined to be a winning outcome in process (414), the gaming device selects the winning cards, randomly or otherwise, in process (430) and the other cards to fill out the dealt and draw hands in process (432). For example if the winning hand was determined to be a three of a kind, three kings may be selected as the winning outcome and seven other cards may be selected as the remaining cards. The gaming device then confirms that the other cards do not result in a win larger than the win associated with the selected winning outcome (e.g., a fourth king is not selected among the other seven cards) in process (434). Once the other cards are confirmed as being acceptable, all of the cards are shuffled and separated into a dealt hand and draw cards in process (436). It is then determined whether the winning hand would be reached from the dealt hand by a player using the best strategy in process (438). For example, if the dealt hand included only one king and four other cards of different matching suit such as four hearts and king of spades, the best strategy would be the hold the four hearts and not the king. Here, the cards would be reshuffled in process (436) until it was determined that the winning hand was reachable by a player using the best strategy.
Once a dealt hand and draw card order has been set for either the winning or losing hands, the dealt cards are displayed to the player in process (440). The gaming device waits for the player's input to hold cards and request a draw in process (442). The gaming device then displays a final poker hand and awards any prizes associated with the final poker hand in process (444). The gaming device may than wait for further player input in process (446).
