SOLUTION: When a hit ball wins a prize in one of a start prize winning ports 4a-4c, the three patterns of a pattern display device 25 starts scroll change and change display is stopped after a fixed time. When the combination of the stopped display patterns is the one for a big hit, the game state is adopted as the special one and opening/closing members 27a and 27b are opened for a fixed time. In this case, the value of an operation start cumulative counter is updated one by one in the case of detecting the start prize winning ball from a power source supply when an arcade opens and it is discriminated whether the value is smaller than a prescribed number, for example, 51 or not. In the case of YES in the discrimination, the probability is increased at the time of a bit hit regardless of the combination of the bit hit patterns and the atmosphere of the game arcade is stirred-up when the arcade is opened. |
