To provide a Pachinko machine in which a game ball does not fall from a game domain even if the front door is opened.

A game board is arranged at the back of the front door. The game domain, in which the game ball is struck, is formed on the game board, the game domain is exposed when the front door is opened, and maintenance of eliminating ball jamming can be performed. The game board includes a magnetic plate and an electromagnet, which is actuation controlled with a magnetization control part, is connected to this magnetic plate. The magnetization control part magnetizes the magnetic plate by operating the electromagnet, when the front door is opened, and attracts the game ball within the game domain to the magnetic plate. Thereby, even if the front door is opened, the game ball does not fall from the game domain.
