PROBLEM TO BE SOLVED: To prevent all game balls passed through a passage gate from entering into an electrically-driven variable prize-winning device, restrain balls from entering excessively and enhance fun of a Pachinko game machine as a game. SOLUTION: This game machine is provided with a ball sensor 10 for detecting passage of game balls p at a passage gate 3 disposed on a game board, and an electrically-driven variable prize-winning device 4 which is turned into its opened state from its closed state by detecting the passage of the game balls with the ball sensor at a lower part of the passage gate where the game balls can flow down. In this case, the opening time of the electrically-driven variable prize-winning device is set in a short period in which the game balls passed through the passage gate cannot enter into the electrically-driven variable prize-winning device in the opened state at ordinary times, and in a long period in which the game balls passed through the passage gate can enter into the electrically-driven variable prize-winning device in the opened state at specific times. |
