To provide a pachinko machine capable of providing a situation in which a game ball received on the inner surface of an open/close door enters a winning hole and a situation in which the game ball does not enter the winning hole when the winning hole is opened via the open/closed door by devising the inner surface of the open/close door for opening/closing the winning hole to allow a player to enjoy the game of making game balls enter the winning hole.

A large winning hole guiding part 25 for guiding the game ball received on the inner surface 24 into a large winning hole when the open/close door 12 is turned to open the large winning hole, and a game area guiding part 26 for guiding the game ball received on the inner surface 24 onto a game area again are formed on the inner surface 24 of the open/close door 12 for opening/closing the large winning hole. With this structure, the game ball received by the large winning hole guiding part 25 of the open/close door 12 is guided into the large winning hole, while the game ball received by the game area guiding part 26 is guided onto the game area again.
