So I did a little investigating, and it turns out that you’ve guessed the answer–both magnets and different-sized cue balls are used, depending on the table.įor those not familiar with coin-operated pool tables, all the balls are held inside the table until the coins are inserted, after which they all fall out. I recently pondered this myself after my lady and I used a coin-operated table for the first time, and she was surprised that after I scratched (as I frequently do) the cue ball would return to play. If so, is there any difference between how cue balls with and without the load react? How are they made? Do you have to buy a certain kind of cue ball in the event that the one you have is stolen? Are they more expensive? Then again, I'm probably way off track.

The only thing I can think of is some sort of metallic load built into the ball with the same properties as the material it is displacing (sort of like casino dice which are the same weight on all sides despite the different number of divots on each side) I'm assuming that this would enable the pool table to use magnetism to identify the cue ball. How do pay-per-play pool tables know which ball is the white ball and return that one to you when you scratch? It can't be a difference in size, mass or density because that would alter how the balls react after they make contact with the cue ball.
