PROBLEM TO BE SOLVED: To prevent a replay time from becoming monotonous by emphasizing such game properties that the probability of winning a replay is gradually increased. SOLUTION: Two winning combinations RP1 and RP2 are set as replay winning combinations in the slot machine. In addition, A-modes (A1 and A2) in which the probability of winning the replay based on these winning combinations is higher than in a regular game state, and B-modes (B1 and B2) in which the probability of winning the replay is higher than in the A-modes are also set in the slot machine. The A-mode starts when a bonus game is terminated and the B-mode starts on condition that the RP2 is won. Since the probability of winning the RP2 in the regular game state is very low, the shift from the regular game state to the B-mode rarely occurs. On the other hand, since the probability of winning the RP2 in the A-mode is higher than in the regular game state, the shift to the B-mode is established with a prescribed frequency. The probability of winning the RP2 is greatly increased in the B-mode. COPYRIGHT: (C)2007,JPO&INPIT
