  • Patent number: 6471590
    Abstract: A cashless peripheral method interfacing with a gaming system. The gaming system issues a “cash-out” signal when a player quits playing and receives a “cash-in” signal when a player desires to play a game in the gaming system. A stack of unprinted tickets is stored in the interior of the device. A ticket printer prints a coded value, such as a bar code, on a ticket in response to a cash-out signal from the gaming system. A ticket reader reads the amount printed on the ticket. If the printed value corresponds to the value which should have been printed, a ticket-out transport delivers the printed ticket to the player cashing out from the gaming system. When a player inserts the printed ticket into the device a ticket-in transport senses the insertion and the ticket reader reads the coded value from the inserted printed ticket. The ticket reader issues a cash-in signal to the gaming system corresponding to the value read from the coded value on the inserted printed ticket.

  • Patent number: 6398218
    Abstract: A method is set forth for playing a bonus game in a secondary slot machine adjacent a primary slot machine. The primary slot machine issues a bonus qualifying signal to the secondary slot machine to start play of a bonus game when a bonus qualifying event occurs. The reels of the bonus game include value symbols, null symbols, and end game symbols which may be of two basic types: a lose game symbol and a stop game symbol. After the random spin, the values of any value symbols displayed on the payline of the secondary slot machine are accumulated into an accumulated winning value. The value symbols could include positive integer values, negative integer values, and multiples. The random spinning, determination of values of any-value symbol and the accumulation of a winning value is repeatedly continued until an end of the bonus game occurs.

  • Patent number: 6340158
    Abstract: A Pachinko bonus game system for an underlying game machine. The Pachinko bonus game has a playing field with a plurality of rows of pegs. A ball is launched onto the playing field by a launch mechanism when an initiate condition occurs during play of the underlying game. A row of lanes are provided on the playing field. The ball, after traversing among the pegs on the playing field, eventually travels through one of the lanes. At each lane is randomly displayed a bonus payoff value. The lane the ball travels through senses the presence of the ball and the value displayed for that lane is added to the credit meter in the underlying game. The bonus payoff values are randomly changed from game to game which eliminates any mechanical bias present in the Pachinko game. A stand-alone Pachinko game as well as using a Pachinko game as a coin dispenser is also provided.

  • Patent number: 6217448
    Abstract: A method for providing bonus jackpot payoffs during a bonus mode time period in a system of linked gaming machines interconnected to a controller. Eligible gaming machines are determined at the time the bonus time period starts. Once the bonus mode time period starts, a portion of the eligible gaming machines are randomly selected for multiple jackpot bonus payoff opportunities. The random selection determines the rate the opportunities are issued and the average length of the bonus mode time period. Once gaming machines are selected they are allowed to complete the game they are currently involved in and should the play result in a winning combination, then the game payoff is multiplied by a bonus multiplier. The underlying gaming machine is responsible, in a conventional fashion, for paying the game payoff and the controller then authorizes a further jackpot bonus payoff of the bonus multiplier less one times the game payoff. The bonus pool value is then decremented by the amount paid by the controller.

  • Patent number: 6210275
    Abstract: The present invention relates to a progressive game that can be incorporated either as a bonus game or a stand-alone game in a progressive linked gaming machine environment. The game utilizes a plurality of progressive jackpot pools each associated with a particular game outcome (i.e., such as Quiniela, Exacta, Trifecta and Superfecta in the case of a horse race derby game). Each progressive jackpot pool is funded through play at the underlying linked game such as a contribution of each wager or through separate wagers. When the game of the present invention initiates, a plurality of successive game rounds are played. Each successive game round reduces the number of possible game outcomes such as by reducing the number of horses in each successive horse race. Therefore, with each successive game players have a higher probability of winning. The terminating round is reached in which the last game always results in at least one guaranteed winner through reduction of the possible game outcomes.

  • Patent number: 6193235
    Abstract: A casino card game using a deck of cards having a number of value cards and a number of subsets of cards. A first subset constitutes value cards which have value in the play of the game to provide winning combinations according to the game rules. A second subset are wild cards that assume the value of another value card in a players hand. A third subset of cards are player specific cards which when matching an identifier separately associated with the player, assumes special meaning in the players hand. A fourth subset termed worthless cards which have no value and occupies space in the hand. A fifth subset are losing cards which causes a hand to immediately lose. A sixth subset is termed contingent cards which causes the player to receive additional payoff when the player has a winning combination of value cards. A last subset are win cards which causes the hand to immediately win.
