  • Gaming system incorporating non deterministic jackpot
    Patent number: 6592458
    Abstract: A gaming system incorporating a non-deterministic jackpot is provided. In a first embodiment, the gaming system generates a random number to determine a probability of winning and a jackpot amount. A contribution rate is predetermined, and a portion of each bet placed on a gaming machine associated with the system equal to the contribution rate multiplied by the amount of the bet is placed in a contribution pool. The gaming machine on which a bet causing the contribution pool to be greater than or equal to the jackpot amount is awarded the jackpot. According to a second embodiment of the present invention, a first random number within a range is generated. A second random number is generated for each bet placed on a gaming machine associated with the system. The jackpot is awarded to a gaming machine on which a bet resulting in a second random number equal to the first random number was placed.
