<P>PROBLEM TO BE SOLVED: To provide a game machine improving the amusement of a game by vaguely notifying of a high-probability game state, while preventing a fraud executed by intentionally raising a winning probability on a game parlor side and tempting players into playing from the time of opening business. Ž<P>SOLUTION: In a case where a low-probability game state is determined, a sub CPU 102a in a performance control board 102 determines a chance mode. In a case where a high-probability game state is determined, if determining that a winning game ball is entering a second operation-start hole when a pair of movable pieces 10b are drivingly controlled into an open state, the sub CPU 102a determines either of the chance mode and a probability variable mode and, if determining that a winning game ball is entering the second operation-start hole when the pair of movable pieces 10b are drivingly controlled into a closed state, determines the probability variable mode without determining the chance mode.
