9-Ball Rules: The Complete Guide

Nine-ball is pool's fastest format: nine balls, one goal — legally pocket the 9 and you win. This guide covers the official WPA rules, then flags where league nights and bar tables commonly play it differently.

The object of the game

Balls are played in rotation: the cue ball must contact the lowest-numbered ball on the table first on every shot. You do not have to call pockets — any legally pocketed ball stays down. The player who legally pockets the 9-ball wins the rack, whether it falls on a normal shot, a combination, or the break. (For how the game compares to its cousins, see how 8-ball, 9-ball and 10-ball actually differ.)

The rack

Nine balls are racked in a tight diamond: the 1-ball at the apex (toward the head of the table) and the 9-ball in the center. Under the current WPA rules the rack is positioned so the 9-ball sits on the foot spot; some tournaments instead elect to place the 1-ball on the spot. The other balls go in without any intentional pattern. Most leagues and events use a template rack for tightness — how to rack for 9-ball, rules and unwritten etiquette covers the details.

The break

• The cue ball begins in hand anywhere behind the head string.
• If no ball is pocketed, at least four object balls must be driven to a rail — fail that and it's a foul, giving the opponent ball in hand anywhere.
• On a dry break the current WPA rules also require three balls to cross the head string; a break that misses this is an "illegal break" handled under Regulation 16 (the Three-Ball Break Rule) — it exists to stop soft, safe breaking.
• Pocketing the 9 on a legal break wins the rack. If the 9 falls on a fouled break or a push-out, it is spotted back — only the 9 is ever re-spotted.

The push-out

Immediately after a legal break, the player may call a "push-out" — a special shot in which no ball has to hit a rail or a pocket. Declare it before shooting. The opponent then chooses to take the shot themselves or hand it back. A 9-ball pocketed on a push-out is spotted and does not win. Push-outs exist for one reason: when the break leaves you nothing, you can improve the position instead of attempting a miracle.

Legal shots

After the break (and push-out), a shot is legal when:

1. The cue ball contacts the lowest-numbered ball on the table first, and
2. After that contact, a ball is pocketed or any ball — cue or object — reaches a rail.

Anything less is a foul, and the incoming player gets ball in hand anywhere on the table. Combination shots are legal (you may hit the lowest ball into the 9 to win early), as are jump shots executed with a downward stroke — scooping under the ball is a foul.

Fouls

• Cue ball scratched or driven off the table
• Lowest ball not contacted first
• No ball reaches a rail after contact (when nothing is pocketed)
• Object ball driven off the table — it stays out of play, except the 9, which is spotted
• Double hit, push shot, or scoop jump
• Foot not touching the floor
• Shooting out of turn or disturbing the balls illegally

Every foul gives the opponent ball in hand anywhere.

The three-foul rule

Three consecutive fouls by the same player in one rack means loss of rack. The warning requirement is real: the referee — or your opponent in self-officiated play — must tell the shooter when they are on two consecutive fouls. Without the warning, a third foul counts only as the second. Note that this rule does not exist in 8-ball.

Winning the rack

• Pocket the 9 legally at any point — normal shot, combination, carom, or the break.
• Or the opponent commits three consecutive fouls.

Where league and bar rules differ

Official WPA rules are the baseline, but the major league systems genuinely do not play the same game — always check your league's rulebook:

• APA (American Poolplayers Association): 9-ball is scored by points, not rack wins — legally pocketed balls carry point value and matches are races to a points target set by your handicap, so you can lose a rack and still bank points from it. Check your local APA bylaws for the exact scoring table and any division-specific rules.
• BCA Pool League / USAPL (CueSports International): closer to the pro game — the 9 wins the rack, the push-out is live, and the three-foul rule applies. Under USAPL scoring a rack win is worth 14 points while the loser earns one point per ball pocketed; a 9 on the break scores 14–0.
• Bar and house rules: expect variation — some re-spot a break-pocketed 9 or require it in a called pocket, some don't enforce the three-foul rule at all, and some restrict ball-in-hand to behind the head string after a scratch. WPA 9-ball itself is not call-shot, though casual games sometimes require calling the money ball.
• Push-out: WPA and BCA-style play allow one push-out after the break; casual play often ignores or misapplies it.
