PROBLEM TO BE SOLVED: To provide a game machine capable of effectively monitoring dishonest use of a magnet.SOLUTION: A start port and a big winning port provided in a game board are controlled to open and close respectively by solenoids, and a magnetic sensor provided on the game board and detecting magnetism of a magnet used dishonestly is capable of detecting even magnetism emitted from the solenoids. When magnetism is detected longer than the predetermined longest period which can occur in control as a total continuation period when the continuation periods of the plural solenoids overlap, detection information representing detection of irregular magnetism is outputted. |
