9-Ball vs. 10-Ball: The Differences Explained
9-Ball and 10-Ball are both "rotation" games: you must always hit the lowest-numbered ball first. They look almost the same, but a few rules make them play very differently. Here's what changes.
Quick comparison
- Balls: 9-Ball uses balls 1-9; 10-Ball uses 1-10.
- Rack: 9-Ball is a diamond with the 1 at the front and the 9 in the middle. 10-Ball is a triangle with the 1 at the front and the 10 in the middle of the third row.
- Winning ball: the 9 in 9-Ball, the 10 in 10-Ball.
- Calling shots: 9-Ball is usually "slop": any legal shot that makes a ball counts. 10-Ball is call shot: you must call the ball and pocket.
- Money ball on the break: in 9-Ball, the 9 on the break wins. In 10-Ball (under WPA rules), the 10 on the break is spotted and does not win.
Why 10-Ball is harder
With an extra ball and a tighter rack, it's harder to make a ball on the break and harder to run out. Call shot rules take away lucky rolls: if you make a ball you didn't call, your opponent can choose to shoot or give the shot back to you. That's why many pros call 10-Ball the purer test, and why big money matches are often played at 10-Ball (see our Shane Van Boening story).
What's the same
- You must hit the lowest ball first on every shot.
- After the break, the incoming player may "push out" to a better position, and the opponent chooses who shoots next.
- A scratch or foul gives ball in hand anywhere on the table.
- Three fouls in a row loses the game under WPA rules.
Which should you play?
9-Ball is faster and more forgiving and is the main game at the big pro events like the US Open. 10-Ball rewards control and safeties. Play both: 10-Ball practice makes your 9-Ball better.
