PROBLEM TO BE SOLVED: To sufficiently arouse the expecting feeling of a game player as against privilege obtaining such as a probability fluctuation, etc., by permitting whether or not a probability fluctuation mode is continued more to rely on in which one of pattern aligning games a hit appears after a mode is shifted to the time shortening one. SOLUTION: The pattern aligning game is executed by a pattern aligning game executing means 70 at the time of the prize-winning of a ball into a specified prize-winning port 12 and a screen game is executed by one of operation modes, a normal mode or the time shortening mode, by a screen game executing means 80 when the ball wins the prize in a specified start port. Moreover, when a prescribed game state is formed, a probability fluctuation mode setting means 90 sets the operation mode in the probability fluctuation one. Then, after the shifting to the time shortening mode, a ready-for-winning state where a hit state is formed when one remaining prescribed pattern is aligned in the pattern aligning game which is executed in a previously decided time appears. When the hit appears in the pattern aligning game which is not the previously decided time, the probability fluctuation mode is released. |
