PROBLEM TO BE SOLVED: To provide a game machine which properly detects a game medium.SOLUTION: A variable winning device 22 provided on a game board includes a jackpot pocket, an opening/closing door for opening and closing the jackpot pocket, and a variable winning detection sensor 22e for detecting game balls having entered the jackpot pocket. The variable winning detection sensor 22e has: an oscillation circuit that changes the state from a state of outputting an oscillation signal to a state of stopping the oscillation signal, when a game ball enters a pocket;and a detection circuit for outputting a detection signal on the basis of the oscillation state of an oscillation circuit. The detection circuit includes a comparison circuit that compares the oscillation frequency of the oscillation signal input to the detection circuit with the oscillation frequency of the oscillation signal output from the oscillation circuit. |
