PROBLEM TO BE SOLVED: To provide a game machine capable of enhancing interest in a game also to a player who cannot readily operate a performance operation means in an operation performance for obtaining operation of the performance operation means.SOLUTION: In execution of a button performance, an upper-limit value of a degree-of-expectation meter of which the value increases at each operation button is made proportional to a jackpot degree-of-expectation, and the jackpot degree-of-expectation is made proportional to an operation effective period. Thus, even if the performance button cannot be operated until the upper-limit value of the degree-of-expectation meter is reached within the operation effective period, the jackpot degree-of-expectation can be estimated based on the operation effective period. |
