<P>PROBLEM TO BE SOLVED: To provide a pinball game machine wherein game pins are adjusted easily by making it difficult to recognize the trace of adjustment of the game pins. Ž<P>SOLUTION: The pinball game machine, including a game panel having the game pins implanted in a game area in which the game balls can roll, is so constituted that the game pins may be provided with a pin adjustment mechanism which changes the game pins in diameter and the relative positions between adjacent game pins implanted in the game panel, and that the game machine may include a control means to control the diameters and the relative positions of the game pins by applying a predetermined voltage to the pin adjustment mechanism. The game pins change in diameter by the application of the predetermined voltage, and the game pins are subjected to the control of the application of the predetermined voltage. Therefore, the game pins are easy to change in diameter by the application of the voltage, so that the trace of the adjustment of the game pins is difficult to recognize, and thereby the game pins are adjusted easily.
