PROBLEM TO BE SOLVED: To diversify the dropping pattern of the game balls by securing a range of the motion thereof on the surface of a game board. SOLUTION: The pachinko game machine 1 has an outer frame 2 defining the outline thereof and the front frame 4 is openably mounted on the outer frame 2. A glass frame 8 is also openably mounted on the front frame 4 and the game board 16 is arranged in the inner portion of the glass frame 8. An opening is formed at the center of the glass frame 8 and a glass plate 20 is fitted into the opening to enable the visual recognition of the surface of the game board 16 through the glass plate 20. This can increase the recognizable range of the game board 16 by expanding the opening of the glass frame 8 and thus, enables the formation of a large surface for the game board 16 accordingly.
