<P>PROBLEM TO BE SOLVED: To prevent magnet cheating without lowering an operation rate. Ž<P>SOLUTION: The accessory 12 of a Pachinko game machine (second type) is provided with a stage 20 where a V winning port 22 is formed. Electromagnets 25, 26a and 26b are provided on the rear part and both side parts of the stage 20 respectively. On the wall part 20c of the stage 20, a magnetism detection sensor 30 for detecting magnetism on the stage 20 is provided. On the basis of a detected result by the magnetism detection sensor 30, when the magnet cheating is conducted, a current is supplied to the electromagnets 25, 26a and 26b. By the magnetism M1 generated from the electromagnets 25, 26a and 26b, the guide of a game ball P by external magnetism M2 generated from a magnet 28 of a cheating person is blocked. Since a game possible state is restored just by stopping current supply to the electromagnets 25, 26a and 26b, the magnet cheating is prevented without lowering the operation rate.
