PROBLEM TO BE SOLVED: To provide a game machine which enables the players to feel expectations for the jackpot over a longer period of time. SOLUTION: The CPU for the performance control starts the special period during which the ready for win state is derived at a higher rate than that in the normal time according to the command from the CPU on the base circuit. Upon the end of the special period, the CPU for the performance control determines the length of the extension of the special period using a table for determining the length of the extended period and the random numbers for determining the length of the extended period. At this point, the CPU for the performance control judges whether the possibility of the jackpot exists in the reservation memory or not and selects the table for determining the length of the extended period corresponding to the result of the judgment. In the table for determining the length of the extended period used when the jackpot exists in the reservation memory, more criteria are allotted to the longer extended period.
