PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a situation where a player's sense of expectation is damaged all the more by a performance relating to a jackpot winning probability.SOLUTION: When receiving a stage lottery command (S2201), a performance control part acquires a stage random number and performs stage random number determination (S2202, S2203). The performance control part determines a RAM clear flag (S2204), and determines whether present winning is small win or latent probability variation when the RAM clear flag is ON (S2205). The performance control part turns OFF the RAM clear flag in the small winning or the like (S2206). Otherwise, the performance control part acquires stage information selected in the last lottery (S2207). The performance control part determines whether the present degree of expectation toward a high probability is higher than the last time (S2208). When the performance control part determines that the present degree of expectation toward a high probability is higher than the last one, the performance control part selects a stage having the degree of expectation toward high probabilities lower than the present one from among a plurality of stages. Contrarily, when the present degree of expectation toward high probabilities is not higher than the last one, the performance control part selects a stage selected in the present lottery, and performs RAM setting (S2209-S2211). |
