PROBLEM TO BE SOLVED: To provide a Pachinko game machine, preventing fraudulence using "dangling board". SOLUTION: An initial value for next updating a random counter which determines a jackpot is calculated by adding a value of a byte counter to the value of the next initial value memory. The value of the byte counter is repeatedly updated by +1 during a residual time in a reset interrupt process. The residual time of the reset interrupt process is an indefinite time varying according to the state of the game and the "dangling board" cannot acquire the indefinite time. Therefore, the value of the initial value of updating the random number counter is varied based on the value of the byte counter repeatedly updated within the indefinite time, so that it is impossible for the "dangling board" to acquire the timing of the occurrence of the big win. Thus, fraudulence using "dangling board" can be prevented. The byte counter has one byte configuration, so that at any timing of reset interruption, the updated initial value of the random number counter will not be a value outside the original update range.
