10 Ball Rules: How to Play 10-Ball Pool

Why 10-Ball Exists

Ten-ball was invented, more or less, to fix what pros saw as a luck problem in 9-ball. In 9-ball, the 9 can drop on the break, on a fluke combo, or off a kick that was clearly a safety attempt. For entertainment television it's great, but for determining who the best player is, it's noisy. 10-ball is called-shot rotation, every pocket must be called, the 10 must be called, and accidental wins are not rewarded.

I came to 10-ball late. For years I played 9-ball exclusively, and when I started taking 10-ball seriously around 2015 I immediately got humbled. Every shot requires commitment. You can't roll the cue ball toward a cluster and hope something drops, if a ball falls in a pocket you didn't call, it spots back up and your opponent gets ball-in-hand. That changes how you think about every single stroke.

Today, most major pro tours have shifted to 10-ball as their primary rotation format, including the World Pool Championship in recent editions. If you want to play the game today's top players are playing, this is it.

The Rack and Setup

Ten-ball uses a standard triangle rack, the same one you use for 8-ball, but with only ten balls. The 1-ball goes at the apex on the foot spot. The 10-ball goes in the middle of the third row, which is the center of the rack. The remaining eight balls (2, 3, 4, 5, 6, 7, 8, 9) fill the other eight positions in random order, except that the 2 and 3 balls must go on the back two corners of the triangle under WPA rules.

Requiring the 2 and 3 on the back corners prevents the breaker from stacking high-numbered balls in predictable positions for wing-ball breaks. This rule was added after pros figured out how to engineer breaks when the rack was free.

The cue ball is placed anywhere behind the head string, just like 9-ball. Modern pro 10-ball breaks are almost always from the side of the box, not from dead center.

Object of the Game

Legally pocket the 10-ball on a called shot. That's the goal. Unlike 9-ball, where any pocket for the winning ball counts, in 10-ball you must call both the ball and the pocket. A 10-ball that falls in the wrong pocket, even on a legal hit and combo, doesn't win the game, it's spotted back on the foot spot and your opponent gets ball-in-hand.

You still follow rotation order, lowest ball on the table must be hit first on every shot. But every pocketed ball must be called. Obvious shots (a straight-in ball into a pocket it's clearly headed for) don't require verbal call, but combinations, banks, caroms, and kick-shots all require calling the pocket in advance.

How to Break

The breaker places the cue ball anywhere behind the head string and strikes the 1-ball first. For a legal break, the breaker must either pocket a ball or drive at least four object balls to a rail. A failed break gives the opponent ball-in-hand anywhere on the table and the option to shoot or pass.

Here's the big difference from 9-ball: the 10-ball pocketed on the break does NOT win the game. Instead, it's spotted back up on the foot spot and play continues. This rule, more than any other, is what makes 10-ball feel different from 9-ball. You can't win on the break. You have to actually run balls to win a rack.

Because of that, 'breaking safely' has become a real tactic at the pro level. Pros will sometimes use a break designed not to pocket any ball but to leave a clustered rack and a tough shot for themselves, then play a safety. It sounds crazy, but it works against top opponents who would run the rack if given any ball-in-hand opportunity.

Legal Shots and the Call-Shot Rule

Every shot in 10-ball must contact the lowest-numbered ball on the table first. After contact, either a ball must be pocketed into the called pocket, or the cue ball/object ball must reach a rail. Balls pocketed in uncalled pockets are spotted back on the foot spot, and unless you pocketed the called ball in the called pocket, it's a foul, ball-in-hand for the opponent.

The call-shot requirement is what separates 10-ball from rotation games like 9-ball. If you bank the 4 cross-side and it rolls off the rail and drops cross-corner instead, it doesn't count. You called cross-side. The 4 spots back, and your opponent gets to shoot. I've lost racks to this exact scenario and it hurts, but it's also the rule that makes 10-ball a better test of skill.

Fouls and Penalties

The standard penalty for a foul is ball-in-hand anywhere on the table. Common fouls include: failing to hit the lowest ball first, failing to pocket the called ball into the called pocket, failing to drive a ball to a rail after contact when no ball is pocketed, pocketing the cue ball, jumping the cue ball off the table, and double-hitting the cue ball.

A unique situation: if you pocket the called ball into the called pocket AND an uncalled ball into an uncalled pocket, the called ball counts but the uncalled ball is spotted. You stay at the table. If you pocket only the uncalled ball and miss the called ball, it's a foul regardless, ball in hand for the opponent.

Three consecutive fouls by the same player equals loss of game, same as 9-ball. Warnings must be issued after the second foul.

The Push Out

The push-out rule works the same as in 9-ball. On the shot immediately after a legal break, the shooter can announce 'push out' and play any shot without obeying the rotation or rail rules. Balls pocketed on a push-out don't count (except the 10-ball, which spots up). After the push-out, the opponent chooses to shoot or pass it back.

Push-outs are more common in 10-ball than in 9-ball because the denser rack and the 10-in-the-middle position produce hooked breaks more often. If the cue ball hides behind the 8 or 9 after your break, pushing out to an open table is often the smart play.

Winning the Game

You win by legally pocketing the 10-ball into a called pocket, on a shot where you hit the lowest ball first, and where the shot is otherwise legal. Because the 10 usually requires working through most of the rack, 10-ball games tend to last longer than 9-ball games, 45 seconds to a couple minutes per rack is typical at the amateur level, longer at the pro level where safety battles are common.

Matches are played as races, just like 9-ball. Race-to-7 or race-to-9 is common for amateur play. Pros play races-to-11 or longer. Because the format rewards consistent play more than streaky play, 10-ball races tend to be closer to the true skill gap than 9-ball races of the same length.
