PROBLEM TO BE SOLVED: To provide a game machine capable of achieving desired security operation by lightening a game control load of a CPU.SOLUTION: A random number generation circuit GNR includes: a numerical value update part 33G for updating a numerical value by repeating update operation; and a random number acquisition part 34G capable of acquiring a numerical value of the numerical value update means 33G in accordance with a switch signal. The random number generation circuit GNR is configured so as to obtain a numerical value from the random number acquisition par 34G or the numerical value update part 33G when the switch signal is ON. Provided are start means for starting updating a numerical value within a numerical value range of 0 to 2-1 from a random initial value in accordance with power-on, and change means for starting from an initial value differing from an initial value until then and continuing update operation of the numerical value update part 33G when a numerical value generated by update operation of the numerical value update part 33G makes the cycle of a numerical value range of 0 to 2-1. As far as the power of a CPU is not reset, the change means functions repeatedly. |
