You know, the pay-to-play ones where each ball that gets hit into a hole and gets returned into the holding chamber. But when you hit the que ball in a hole, it returns it to a special area where you can retrieve it again. How the heck does it know the difference??|||i believe the Que ball weighs more than the other balls|||I thought it was the diameter of the queball...larger or smaller, I couldn't say.|||the cue ball is heavier or lighter , i can't remember, bt anyway when it rolls down the weight makes it take another route.
