PROBLEM TO BE SOLVED: To allow a player to guess a game state without concentrating the player's interest in a symbol variation performance.SOLUTION: On the basis of a detection of a game ball by a passage ball detection sensor, a main control CPU as opening/closing condition determination means determines an opening/closing condition of an opening/closing member that opens/closes a winning hole of an operation-start winning device; a symbol display device executes a symbol variation performance on the basis of a ball detection by the operation-start winning device; and a normal symbol display executes a normal symbol variation on the basis of the ball detection by the passage ball detection sensor. On the basis of the detection of a game ball by the operation-start winning device, the game machine determines one game state from a plurality of game states with difference prize amounts; in a state of a low probability state without variation-time shortening and a high probability state without variation-time shortening, causes the symbol display device to execute a symbol variation performance of a same performance content; and in the low probability state without variation-time shortening and the high probability state without variation-time shortening, differentiates opening/closing conditions determined by the main control CPU. |
