PROBLEM TO BE SOLVED: To securely prevent a fraudulent player from gaining a profit from the conduct of alternately shooting and stopping shooting pachinko balls. SOLUTION: A CPU 31 counts up the value in a shooting stopping counter 34 by one in response to the detection of the stop of shooting of pachinko balls 7. The CPU 31 stores alternate shooting/stopping shooting conduct confirming data in a RAM 32 if it determines that the value in the shooting stopping counter 34 is counted up by three in five minutes. If the shooting/stopping shooting conduct confirming data are stored in the RAM 32 when a pachinko ball 7 enters a winning hole 11, the CPU 31 determines whether the number of shot balls measured after the alternate shooting/stopping shooting conduct confirming data are stored in the RAM 32 till the pachinko ball 7 enters the winning hole 11 is not more than 500. If it determines that the measured number of shot balls is not more than 500, the CPU 31 outputs the voice announcing that the conduct of alternately shooting/stopping shooting is performed from a speaker 44, and controls the play not to be shifted to a jackpot mode.
