PROBLEM TO BE SOLVED: To block players excessively committed to playing from feeling excessive expectations by notifying them of the hit of a dropping lottery. SOLUTION: While a time shortening game is executed, game balls are stored in a game ball storage part 330 provided in a non-playing area above a starter slot 25 in the game area. When the probability state is altered from the high- to low-probability state, the game ball storage part 330 is opened to make players that the alteration is made to the low-probability state from the high-probability state. On the other hand, while the probability of winning the starter slot 25 in the playing area is heightened in the low-probability state when players are so-called stuck in hopeless gut.
