PURPOSE: To prevent alteration of a random number generating program, reduce load of a ROM program, prevent generated random numbers from appearing cyclically, and facilitate program structuring and verification. CONSTITUTION: A control system with a random number function is formed for a game machine by connecting to a central processing unit 10 various units, including a control ROM 14 provided with an upper and lower limit setting area, a prizing timing detector 26, and a random number generator 28 separated from the central processing unit 10 and provided with a counter 30 which counts, based on a value set by an upper limit setting resistor 38 or/and a lower limit setting resistor 34, signals from a signal generator 32, to generate the counted signal as a random number by a control unit. |
