They play cue ball fouls only. And they have a ref/racker working every money match. He gets a small commission from the winner of the match (5-10%). The ref will actually mark a ball or balls that are close to the cue ball in case they get moved during the shot. That way he knows where to restore the ball.
The filipino refs are only the best in the world! First of all, they're all players so they know the game. And they are dedicated referees who don't miss a thing.
Sounds like a great time! Thanks Jay!
