  • Patent number: 6343988
    Abstract: A method and apparatus for using player input codes (e.g., numeric, biometric or physical) to affect the outcomes of electronic gambling devices, such as slot machines. The player inserts money into the slot machine and enters an input, e.g., a lucky number or biometric measurement, into a device attached externally to the slot machine. A central processing unit (“CPU”) within the slot machine receives the input and directs a random number generator to produce a random number. The CPU retrieves a combination algorithm from an algorithm database and then applies the combination algorithm to the player number and the generated random number to form a combined value. The CPU looks up the combined value in a probability table to determine resulting reel positions. The CPU looks up the reel positions in a payout table to determine the amount of money won or lost by the player.

  • Patent number: 6342007
    Abstract: The player is dealt an initial hand of five cards, all face up. If four of these first five cards are of the same suit, the player is offered the opportunity to proceed to a second video screen in which the remaining nine cards of that suit are displayed to the player. One of these nine cards is randomly selected and added to the player's initial five card hand. The player is assured of achieving at least a Flush with the possibility of improving his hand to a Straight Flush or a Royal Flush depending on the first four cards and the fifth card selected. After this random selection of the fifth card, the player's hand is evaluated to determine what poker hand ranking the player has achieved and the player is paid an award based on the amount wagered by the player in accordance with a pay table.

  • Patent number: 6315664
    Abstract: The present invention relates to a bonus scheme for a gaming device which presents a plurality of indicators to the player. Each indicator may be a success indicator or a failure indicator based on a pre-determined probability. Upon or prior to the selection of the indicator, the processor in the gaming device determines, based on that probability, if the indicator is a success indicator or a failure indicator. When a player selects an indicator, the gaming device displays if the selected indicator is a failure indicator or a success indicator and a value associated with the success indicator, The player selects indicators until the player selects all of the success indicators or the player selects a failure indicator. Accordingly, based on chance and the pre-determined probability, a bonus round may include all success indicators and no failure indicators to increase player excitement and enjoyment.

    Abstract: A slot machine is configured to have a main game comprising a multi-reel payline mechanical reel or video reel slot arrangement with at least one payline and a secondary event game comprising a multi-reel, one or more payline mechanical slot arrangement. Whenever the player achieves a combination of symbols on the main game that awards the player with the secondary event game, the number of chances provided to the player to play the secondary event game is based on the number of paylines that the player has played on the main game or by the number of credits wagered on each payline. Alternatively, the number of spins awarded to the player on the secondary event game can be determined by the symbol combinations achieved by the player on the main game. All spins of the three reel secondary event game can be winning spins or, alternatively, the spins on the secondary event reel game can be either winning or losing spins.

  • Patent number: 6068552
    Abstract: A gaming device such as a video based slot machine provides a player the ability to modify at least one parameter of the slot machine. The slot machine then modifies other parameters to ensure a desired house advantage. Odds, payout schedules and wager amounts may be customized by a player, and the slot machine automatically determines changes in other parameters which were not customized to maintain a constant house advantage. Software running on the slot machine uses an equation that takes into account pertinent parameters or variables such as size of jackpot, amount wagered taken in at each pull, and probability of hitting the jackpot at each pull. Based on the equation, the software adjusts parameters other than the one(s) specified by the player so that the outcome (the house advantage) remains constant with each pull. A player interface provides an easy to use method of modifying selected parameters.

  • Patent number: 5547192
    Abstract: In a slot machine, a token is inserted to play a game. The slot machine pays tokens when the game results in a win, which comprises a normal win, or a big win for which more tokens are paid than for the normal win. The game comprises a normal game, or a bonus game whose winning probability is higher than the normal game. The bonus game is triggered when a big win is acquired. The slot machine generates a play signal representing a play of the game and a big win signal representing a big win. A display apparatus is associated with the slot machine, and has 16 DIP switches which are set with reference to the slot machine, and signal information regarding the slot machine. In the display apparatus, a normal game counter counts the times of having played the normal game between the completion of playing the bonus game and the occurrence of a big win, whereas a big win counter counts the number of times of a big win.

  • Patent number: 5524888
    Abstract: A gaming machine uses a time-based method for generating game results having nonuniform probability. The gaming machine employs an addressable memory in cooperation with a counter and a clock. The clock generates a very fast series of pulses, and includes a digital-to-analog converter. The counter holds a number representing one of the possible reel stop positions and counts the clock's pulses, so that with each pulse, the value of the counter advances by one. To vary the odds that a particular reel stop position will be selected, the clock's pulses do not come at even intervals. Rather, the clock is responsive to a digital input signal to control how long it will allow a particular number to remain in the counter before the next clock pulse. The binary numbers which are used to control the clock are stored in memory. The memory accepts as input the current value of the counter. Thus, when the counter is incremented, the memory provides the binary number associated with the new counter value.
