To provide a game machine capable of providing the pleasure derived from a pachinko game for a player.

A main control circuit board controls the shifting operation of advancing/retreating of a movable member 12. The movable member 12 mounted on the right side of a center frame 10 is advanced when a "crow-driving ready-to-win" game state is executed in an LCD 3. When the movable member 12 is advanced, balls flowing down on the right side of the center frame 10 can easily flow into a ball inlet 10b of a transfer passage 10a by a guide part 12a of the movable member 12, and more balls are guided to a pattern operation hole 4 via the transfer passage 10a than when the movable member 12 is retreated. Accordingly, when the movable member 12 is advanced, the player plays a right-hand shooting game while expecting that more balls will enter the pattern operation hole 4a. In this way, the game machine can provide the player with pleasure derived from the pachinko game which makes the player have a different degree of expectation according to the state of the movable member 12.
