PROBLEM TO BE SOLVED: To provide a game machine capable of maintaining an originally set winning rate by deriving the opposite result that one is advantageous, the other leads to loss by winning rate adjustment. SOLUTION: When a passing port side opening area 47 is reduced by adjusting a game spike 44 for the winning rate adjustment, the passing rate of a normal pattern start port switch 94 increases and a second winning is easily generated. Further, when the second winning is generated during a second winning induction state wherein the second winning is easily generated, shift control to the second winning induction state is performed again. Thus, the winning rate adjustment putting burdens only on a player is suppressed. COPYRIGHT: (C)2009,JPO&INPIT
