PROBLEM TO BE SOLVED: To provide a pinball game machine which has increased interest by facilitating the visual recognition of a game ball passing through the back surface side. SOLUTION: In this pachinko game machine, a game board is formed of a transparent member, and a game ball Ba introduced from the front surface side of the game board through introduction holes 82 and 92 to the back surface side, made to roll on a first back surface path 83 and a second back surface path 93 and made to pass through is visible. A belt driving mechanism 100 for driving a plurality of permanent magnets 113 so as to move by a belt 110 is disposed on the rear side of the first back surface path 83, and a belt driving mechanism 200 for driving a plurality of permanent magnets 213 so as to move by a belt 210 is disposed on the rear side of the second back surface path 93. Thus, the velocity of the game ball Ba made to roll on the first back surface path 83 and the second back surface path 93 and pass through becomes prescribed velocities VA and VB and is decelerated compared to the case of just falling through the first back surface path 83 and the second back surface path 93, and the game ball Ba is easily visually recognized.
