PROBLEM TO BE SOLVED: To solve the problem of a drop in randomness of a random number value for determining the combination of display modes in the conventional game machines attributed to broken continuity of a counted value of a counter for extracting random numbers and the shortage of time to be spent for an incremental processing of the counter. SOLUTION: Firstly, to make the operation of the clock monitor control ready, a CPU sets a clock monitoring register built in a CPU 56 to enable a clock monitor. Subsequently, a stack set processing is carried out to set a directive address of a stack pointer. A system checking processing is made for the clearance of RAMs or others. Then, a random updating processing for display is executed repeatedly. Other game control operations are executed in an interruption processing by an internal timer interrupt periodically generated.
