PROBLEM TO BE SOLVED: To provide a pinball game machine capable of improving the visual interest by the variable optical decoration of a front frame by moving and displaying a plurality of luminous elements with the rotation along an outer periphery of a see-through window. SOLUTION: A plurality of decoration lamps 6a, 6b, 7, 8a, 8b are mounted on an outer periphery of an annular see-through window through which a game zone of a game board can be seen, and the decoration lamps 6a, 6b, 7, 8a, 8b are flickered and moved in such manner that they are rotated along the outer periphery of the annular see-through window when a specific condition is established (in the announcement of large prize, in the REACH (to reach within an inch of winning). Whereby the outer periphery of the annular see- through window, that is, an outer peripheral part of the game zone can be decorated in a rotating movement display mode, which makes the optical decoration of the front frame variable, and improves the visual interest.
