Patent number: 6343988Abstract: 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.Type: GrantFiled: November 12, 1999Date of Patent: February 5, 2002Assignee: Walker Digital, LLCInventors: Jay S. Walker, James A. Jorasch

Patent number: 6342007Abstract: 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.Type: GrantFiled: February 23, 1998Date of Patent: January 29, 2002Inventors: Michael W.

Patent number: 6315664Abstract: 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.

Patent number: 6068552Abstract: 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.Type: GrantFiled: March 31, 1998Date of Patent: May 30, 2000Assignee: Walker Digital, LLCInventors: Jay S.

Patent number: 5547192Abstract: 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.Type: GrantFiled: April 18, 1994Date of Patent: August 20, 1996Assignee: Universal Sales Co., Ltd.Inventor: Kazuyoshi Ishibashi

Patent number: 5524888Abstract: 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.Type: GrantFiled: April 28, 1994Date of Patent: June 11, 1996Assignee: Bally Gaming International, Inc.Inventor: Raymond Heidel
