PROBLEM TO BE SOLVED: To prevent ball circulation paths within game machines group from overuse of lubricant for pachinko balls, and to provide a pachinko game system, which is able to keep smooth and stable ball distribution. SOLUTION: Full ball volume of an upper tank of a ball supplier 2 in a play unit 1 is made detectable by a sensor for detecting full ball volume 3. And a path for overflowed balls 8 is provided on the upper tank 3. Recollected used balls in a lower tank 13 of a ball collector 10 are raised and polished by a ball polishing-raising device 17, then raised into the upper tank 3 to be introduced to the play unit again. Irrespective of detection of full volume with the recollected balls, the ball polishing-raising device 17 is forced to operate by a ball raising control means, and over-raised polished balls are returned through the path for overflowed balls 8 to the ball collector 10. The path for overflowed balls is provided a function to apply lubricant on used balls passing on.
