PURPOSE: To make game playing flexible to prevent the player from loosing interest by determining, if a special playing state arises, whether or not special patterns are selected as being stopped at special pattern display portions, with different probabilities in high- and low-probability states. CONSTITUTION: When a game ball scores, with a normal motor-driven generator 6 being open or closed, a predetermined number of prize balls is released, special patterns start to fluctuate, and the fluctuation is stopped either a predetermined time thereafter or under the control of the player. If all the patterns stopped are the same at pattern display portions L1, L2, L3, a special playing state is initiated in which the door 7 of a big scoring machine opens for a predetermined time or until a predetermined number of balls has scored, and then, if a ball enters a consecutive scoring slot inside the big scoring machine, the door 7 of the big scoring machine opens only for a predetermined number of times after being closed. Thus, when the special playing state arises, whether or not special patterns are to be selected can be determined at a specific probability and so the enjoyability of the game can be enhanced. |
