<p>PROBLEM TO BE SOLVED: To enhance security relating to a random number circuit loaded on a game machine.SOLUTION: A game machine comprises: random number circuit monitoring means (for example, an update monitoring circuit 537) that can monitor occurrence of abnormality in a frequency of a clock signal for a random number (for example, an external clock signal) for updating numerical data stored by numerical value storage means (for example, a hard latch random number value register or a soft latch random number value) of a 16-bit random number circuit 508b, and an update state of the numerical data stored by the numerical value storage means. Random number circuit setting means executes setting relating to the monitoring by the random number circuit monitoring means before the timing of extracting the numerical data from the 16-bit random number circuit 508b. The game machine refers to a Q register value and identifies an address of a data storage area.</p> |
