PROBLEM TO BE SOLVED: To restrain a jackpot in another special pattern game of two special pattern games when materialization of a jackpot in one special pattern game becomes advantageous to players when an advantageous condition such as probability variation or the like occurs. SOLUTION: The game machine has a first start winning opening 51 in which game balls can win any time and a second start winning opening 55 in which game balls can win only when an ordinary variation winning device 53 is opened. When a game ball wins in the first start winning opening 51, a first special pattern game offering a smaller number of acquirable prize balls is performed. When a game ball wins in the second start winning opening 55, a second special pattern game offering a larger number of acquirable prize balls is performed. By frequently opening the ordinary variation winning device 53, varying display time is made shorter for the second special pattern game than for the first special pattern game in the probability variation in which the second special pattern game is easily performed. In the second special pattern game, small wins occur with very high probability. When small wins occur in the second special pattern game during the first special pattern game, the first special pattern game becomes a loss. COPYRIGHT: (C)2009,JPO&INPIT |
