PROBLEM TO BE SOLVED: To improve interest without impairing a desire for a game by performing control to improve a probability to display a special reach condition on a variable display device when the fact that display of the special reach condition is not performed for a prescribed period is detected. SOLUTION: In a variable display device 4, a picture pattern is variably displayed when the picture pattern is basically displayed by a scroll. The picture pattern is displayed on a fixed place without being scrolled, and the picture pattern is switched on the spot. This variational condition is super reach. A slow variation is performed at low speed until the picture pattern being an object of a bit hit passes from this side of two picture patterns being an object of a big hit, and a fast variation is performed at high speed in the other case. This variational condition is display of super reach. A CPU improves a probability in which it is displayed when the super reach is not displayed for a prescribed period, and improves a probability to display it when the super reach is not displayed for a prescribed period. |
