<p>PROBLEM TO BE SOLVED: To improve game properties of a game machine in which right shooting is performed in time of open time extension function operation.SOLUTION: A game machine executes a small win game making a first opening/closing ball entrance port allowing entrance of a game ball flowing down on the right side of a performance display part perform opening/closing operation and a big win game making a second opening/closing ball entrance port allowing entrance of a game ball flowing down on the right side of the performance display part perform opening/closing operation after making the first opening/closing ball entrance port perform the opening/closing operation. The first opening/closing ball entrance port is in an open state over a first time, comes into a closed state by the entrance of a single game ball, comes into the closed state when the first time lapses without the entrance of a game ball during the big win game, and thereafter comes into the open state again. The second opening/closing ball entrance port is in an open state over a second time longer than the first time. When a game ball enters the first opening/closing ball entrance port, the game machine executes a first special performance to indicate whether or not the second opening/closing ball entrance port comes into the open state, and when the first time lapses without the entrance of the game ball into the first opening/closing ball entrance port, the game machine executes a second special performance to indicate whether or not the first opening/closing ball entrance port comes into the open state again.</p> |
