PROBLEM TO BE SOLVED: To provide a game machine capable of suitably improving accuracy of determining passage of a game medium.SOLUTION: A game board 80 of a pachinko machine includes a variable winning device 82, and game balls flowing into the variable winning device 82 are guided to a back side of the game board 80 through a guide passage. A recovery passage communicating with the guide passage is provided on a back side of the game board 80. A first detection sensor and a second detection sensor are provided at a middle position of the recovery passage, and each detection sensor outputs a game ball detection signal to a main controller when detecting the game balls. The recovery passage is formed so that passage speeds of the game balls in the respective detection sensors are made different from each other, and accordingly, lengths of output periods in which game ball detection signals are output from the respective detection sensors are made different from each other. In signal reading processing at the main controller, winning determination processing based on the detection signals from the respective detection sensors and determination processing of determining abnormality of the detection signals by comparing the number of winning determinations, are executed. |
