<p>PROBLEM TO BE SOLVED: To provide a game machine which realizes desired security operation without interfering with its original performance control operation.SOLUTION: A main controller 21 for executing a game control operation comprises: a one-chip microcomputer 21A internally comprises a ROM, a RAM, a random number generation circuit GNR, and a CPU. The random number generation circuit GNR comprises: a counter circuit 42 which circulates within a predetermined numerical range; a circulation detection circuit 43 which detects the counter circuit having circulated within the predetermined numerical range; a bit conversion circuit 44 which receives an output bit from the counter circuit, replaces the bit, and outputs the result; and a holding circuit LRi which stores and holds the output from the bit conversion circuit as a random number value, in response to a change in a switch signal to a predetermined direction.</p> |
