The 9-ball rule, I have never known how to play 9-balls, whether 9-balls win or not, and whether 9-balls can be played directly.

Simply put, it is from 1 to 9 in order, and the person who scores the ninth goal finally wins. The ball hit every time must be the ball with the lowest number on the table, otherwise it is a foul. If you hit another ball when you hit the ball, you can continue to play. If you hit the No.9 ball when you hit other balls, you win. There are still many rules to be familiar with.
