PROBLEM TO BE SOLVED: To provide a pinball game machine capable of easily maintaining a rolling area positioned at the back in the pinball game machine wherein a game ball rolling area is formed in two front and back layers. SOLUTION: In the pinball game machine 10 including a game board 30 having the rolling area where game balls flow down while rolling, the game board includes a first game board 30a having a first rolling area 31c which is arranged at the front to be the side close to a player and has a transparent area where it is possible to view the back to be the side far from the player at least partially, and a second game board 130a having a second rolling area 131c disposed at a position to be overlapped with the transparent area at the back of the first rolling area. The second game board is formed to be movable between the position at which the second rolling area overlaps with the transparent area and a position at which the second rolling area is shifted relative to the transparent area and the forward exposure degree of the second rolling area is increased by less obstruction by the first game board.
