PROBLEM TO BE SOLVED: To increase the game property by reflecting the intention of a game player to the advancing of a game status being advantageous to the game player. SOLUTION: A control device 11 interrupts the opening/closing motion of an opening/closing body 7 when determined patterns by a pattern-displaying device 5 are gathered with a winning pattern. When the game player operates a game-advancing mechanism 3, the control device 11 opens/closes the opening/ closing body 7 for a specified period of time or a specified number of times, and a big jackpot game is advanced, and a game status being advantageous to the game player is presented. In the meantime, when the game player does not operate the game-advancing mechanism 3 because remaining balls to be shot in a tray device are less or none, the control device 11 keeps the opening/ closing body 7 closed. Thus, the advancing of the big jackpot game is interrupted, and the game status being advantageous to the game player is kept under a reserved state. COPYRIGHT: (C)2003,JPO
