Abstract
A progressive jackpot (PJP) system of the invention increments two types of jackpot values. A PJP controller increments a first jackpot value by a percentage of each bet placed on gaming machines. The increment rate of the first jackpot value is predetermined from a payout percentage of the PJP system. A second jackpot value is incremented at a higher rate than the first jackpot value. Each gaming machine or the PJP controller may increment the second jackpot value. The actual amount of an award for a jackpot corresponds to the second jackpot value. The second jackpot value is reduced at appropriate intervals, even if no jackpot has been won. Preferably, the probability of the reduction of the second jackpot value is adjusted, and thereby, the average difference between the first and second jackpot values at the time a jackpot has been won is adjusted to be zero.
