PROBLEM TO BE SOLVED: To properly find out a fraudulent act that unfairly generates a jackpot by obtaining the timing of jackpots. SOLUTION: When the value of an inside random number counter C1 makes a circuit from a start point value C0, a game machine uses a start point value counter Ci to change the inside random number counter C1 or start point value C0, sets a start point value changed flag F2 into a value 1, and stores the value of the start point value changed flag F2 in a reserved ball storage area along with respective counter values. If the inside random number counter value of the reserved ball storage area is determined as a jackpot value, the normal performance mode executes a jackpot when the start point value changed flag value becomes the value 1; the special performance mode executes a jackpot when not the value 1. Consequently, if a jackpot occurs before the start point value C0 is set at the default value, and if the value of the inside random number counter C1 makes a circuit and the start point value C0 is changed according to a reset instruction, the jackpot can be executed by the special performance mode different from the normal mode.
