<P>PROBLEM TO BE SOLVED: To provide a game machine which correctly determines whether or not the same random number values are obtained due to abnormality of a random number generator when the same random number values are obtained during random number monitoring. <P>SOLUTION: The game machine includes: the random number generator 12 including a random number clock generating circuit B51, a plurality of random number tables B53a and a part B52 for determining change of the random number tables for changing the random number tables B53a; a reference clock generating circuit for generating a reference clock; and an abnormality determinator B100 for detecting the abnormality of the random number generator 12. The abnormality determinator B100 includes: a part B101 for obtaining random numbers for determining abnormality and a storage B102 of random numbers for determining abnormality, in which the random numbers are obtained three times for determining the abnormality; a part B103 for comparing the random numbers of determining abnormality and a part B104 for determining abnormality, in which it is determined whether or not the abnormality occurs in the random number generator 12. An interval between obtaining the random numbers for determining abnormality is shorter than a cycle for changing the random number tables B53a and longer than a clock cycle. <P>COPYRIGHT: (C)2011,JPO&INPIT |
