<P>PROBLEM TO BE SOLVED: To change initial value at least for every prescribed count number, without putting a load on software, in a random number generation circuit of a hardware structure and to prevent random number value from being illegally acquired in the case of drawing executed depending on a game progress condition, without causing delay of game processing or deterioration of performance variation. <P>SOLUTION: By generating adjustment count value by a random number generator 300 of the hardware structure, a fraudulent practice is reduced. Since irregular value is added every time when the count value goes around, the initial value is made changeable under high speed count, and security for the fraudulent practice prevention can be strengthened. Since the initial value is changed in the random number generator 300, loads are not put on program processing by software of a main control unit 150 or performance variation of design fluctuation pattern performance is not degraded. <P>COPYRIGHT: (C)2009,JPO&INPIT |
