PROBLEM TO BE SOLVED: To provide a game machine capable of detecting abnormality in random numbers used in the control of games.SOLUTION: A CPU obtains random numbers which a random number generation chip outputs as sample random numbers by performing random number monitoring processing S3, and discriminates whether or not a first sample random number of a comparison sample group Y consisting of a plurality of the sample random numbers and the sample random numbers other than this are the same. Abnormality in the random numbers is detected by the fact that the frequency of becoming the same becomes a frequency not theoretically possible if the random number generation chip is normal.SELECTED DRAWING: Figure 6 |
