PROBLEM TO BE SOLVED: To provide a game machine with game amusement improved by performance conducted on the basis of a discharge operation of a game ball.SOLUTION: In the case where a jackpot occurs during a provability variable status, a performance symbol is stopped to display an ordinary jackpot symbol to produce a jackpot game. If a closing operation of a lower ball removal lever is performed as a ball removing operation during a predetermined period of the jackpot game (i.e., a period when a probability-variation promotion performance is available), a probability-variation promotion performance is executed as a special favor performance. As a result, a game amusement can be improved by giving a surprise or unexpectedness to a player. Moreover, because the probability-variation promotion performance is executed on condition that the lower ball removal lever has been closed, the probability-variation promotion performance can be executed after the ball removal work has been settled, so that the player can concentrate on the probability-variation promotion performance. |
