PURPOSE: To change the big prize probability and uniformly get customers on all game machines by detecting the occurrence of the prescribed game state, and resetting the probability set by a probability setting means when this game state is detected. CONSTITUTION: A control board 50 is connected with a display CPU 62 controlling the display of a normal pattern display device and a special pattern display device, the first solenoid 82 driving a normal electric premium, the second solenoid 84 opening or closing a big prize port respectively, a prize output section 86 outputting the information of prize balls to the control board 50 side, an initial probability setting switch 92 setting the big prize probability when a game machine is excited at the time of the operation start, and a definite probability switch 94 adjusting the appearance probability between multiple big prize probabilities respectively. The occurrence of the prescribed game state is detected, and the probability set by the probability setting switch 94 is reset when the occurrence of the prescribed game state is detected. |
