8-Ball Rules: 14 Common Questions Answered
The game in one line: one player takes the solids (1–7), the other the stripes (9–15). Pocket all of your group, then pocket the 8 to win.
The three ways to lose on the spot: pocketing the 8 early, in the wrong pocket, or on the same shot as a scratch. Those hold in every major ruleset. Almost everything else depends on which rules you are playing, and that is where most arguments start.
"Is that a loss?" is probably the most common question at any pool table. The answer often depends on whose rules you are using. There are three rulebooks most American players meet:
- WPA (World Pool-Billiard Association): the international tournament rules, also used by the Billiard Congress of America. The edition quoted here took effect on October 21, 2026.
- APA (American Poolplayers Association): the biggest amateur league in the US, with its own simplified rules.
- CSI (CueSports International): the rules of the BCAPL and USAPL leagues and tournaments.
Each answer below gives all three, with the rule number so you can check it yourself. Bar and house rules vary from table to table, so if you are playing in a bar, settle the three questions at the end of this article before the break.
Where the rulebooks disagree
| Situation | WPA | APA | CSI (BCAPL) |
|---|---|---|---|
| Calling shots | Every shot after the break | Not required; mark the 8's pocket | Any shot that isn't obvious |
| 8 in on the break | Spot it and play on, or re-break | Win (loss if you scratch) | Spot it and play on, or re-rack |
| Scratch on the break | Ball in hand behind the head string | Ball in hand behind the head string | Ball in hand anywhere |
| Balls pocketed on the break | Table stays open | One group only: that group is yours | Table stays open |
| Scratch while pocketing the 8 | Loss | Loss | Loss |
| Scratch on the 8, 8 stays up | Foul, ball in hand | Loss | Foul, ball in hand |
| Three fouls in a row | No rule in 8-ball | No rule | No rule in 8-ball |
| Jump cue | Allowed | Masters divisions only | Defined in the rules; check event rules |
Highlighted rows are the ones that start arguments. "Behind the head string" is the area at the breaking end of the table, often called the kitchen; WPA calls it "above the head string".
The 8 ball
1. Can you hit the 8 ball first?
Only when it is your object ball, that is, after all seven balls of your group are off the table. Before that, hitting the 8 first is a foul and your opponent gets ball in hand.
- Open table (groups not yet decided): any ball may be hit first except the 8. WPA 4.4, APA "After the Break", CSI 2-5. WPA adds one exception: if a whole group was pocketed while the table was open, the shooter may claim that group and play the 8.
- Groups decided: the first ball the cue ball touches must be from your group. Hitting the 8 (or an opponent's ball) first is a wrong-ball-first foul. WPA 3.2, APA Fouls (b), CSI 2-7.
2. Can the 8 be part of a combination?
It can be hit by another ball, but it cannot be the first ball in a combination until it is your object ball. APA puts it bluntly: the 8 "is never neutral". CSI 2-5 allows it in a combination on an open table as long as it is not the first ball the cue ball touches. But if your combination knocks the 8 into a pocket before your group is cleared, you lose (WPA 4.8(b), APA "How to Win" (b), CSI 2-10(a)).
3. What if you scratch while pocketing the 8?
You lose. This is the one everyone agrees on. Pocketing the 8 and fouling on the same shot is loss of game in WPA 4.8(a), APA "How to Win" (e) and CSI 2-10(a), which makes any illegally pocketed 8 a loss.
4. What if you scratch on the 8 but the 8 doesn't go in?
This is where the rulebooks split:
- WPA and CSI: just a foul. Your opponent gets ball in hand anywhere on the table, and the game goes on. CSI 2-9 says it outright: fouling while shooting the 8 is not a loss if the 8 doesn't go in. In WPA, the list of losing fouls (4.8) only covers pocketing the 8.
- APA: loss of game. Scratching, or knocking the cue ball off the table, when playing the 8 loses ("How to Win" (g)). Missing the 8 completely without scratching, though, is only a foul with ball in hand.
5. What happens if the 8 goes in on the break?
- APA: you win, unless the cue ball also scratches or leaves the table, which makes it a loss.
- WPA: not a foul and not a win. The breaker chooses: spot the 8 and continue, or break again (4.3(e)). If the breaker fouled, the opponent chooses between spotting the 8 and taking ball in hand behind the head string, or breaking again (4.3(f)).
- CSI: same idea. Spot the 8 and accept the table, or re-rack and break (2-4). After a foul, the opponent gets ball in hand anywhere with the 8 spotted, or the re-rack.
The break and the open table
6. What happens if you scratch on the break?
Your turn ends and your opponent gets ball in hand, but where they can place it depends on the rules:
- WPA: behind the head string, or they can take the table as it lies (4.3(h)).
- APA: behind the head string, and the first object ball they hit must be outside the head string. This was added to the APA manual for the 2026/27 league year; older printed copies say otherwise.
- CSI: anywhere on the table (2-3).
A break also has to be legal. In WPA and CSI rules, if no ball is pocketed at least four object balls must reach a cushion, or the opponent can have the balls re-racked. Every break situation, including blackball rules and the 9 on the break, is compared in 8-ball on the break.
7. When are solids and stripes decided?
- WPA: the table is open after the break no matter what went in. The first player to legally pocket a called ball gets that group (4.4).
- CSI: also open after the break; groups are set by the first ball legally pocketed after the break, and you can't claim a group on a safety (2-5, 2-6).
- APA: if the breaker pockets balls from only one group, that is their group. If both groups go in, the table stays open.
Calling shots and pockets
8. Do you have to call your shots?
- WPA: yes, on every shot except the break. You name one ball and one pocket if they aren't obvious; cushions and kisses don't need calling. You may call "safety" instead, which ends your turn even if a ball drops (4.6, 1.7).
- CSI: you must call any shot that isn't obvious, such as banks, kicks and combinations; obvious shots need no call (1-16). You can declare a safety (2-8).
- APA: ordinary shots don't need calling, and any of your balls pocketed without a foul counts ("slop" is fine). The exception is the 8: its pocket must be marked, usually with a coaster.
9. What if the 8 goes in the wrong pocket?
You lose, in all three rulebooks: WPA 4.8(c), APA "How to Win" (c), CSI 2-10. In APA, failing to mark the pocket at all is also a loss if your opponent calls it.
10. What if the 8 drops on the same shot as your last ball?
Loss. APA ("How to Win") and CSI (2-10(c)) both say so in as many words. WPA has no separate clause; its rule that you lose if the 8 goes in before your group is cleared (4.8(b)) covers the case.
Driving the 8 off the table is also loss of game (WPA 4.8(d), CSI 2-10(b), APA "Balls on the Floor"). In WPA and CSI rules the exception is the break, where the 8 is spotted instead.
Fouls and penalties
11. What counts as a foul?
The penalty for an ordinary foul in 8-ball is the same everywhere: ball in hand, meaning the opponent may place the cue ball anywhere on the table. The standard fouls are:
- Scratch: the cue ball goes in a pocket or off the table.
- Wrong ball first: the cue ball's first contact is not one of your balls (or the 8 when you're on it).
- No rail after contact: if nothing is pocketed, after the cue ball hits a ball, some ball (cue ball or object ball) must touch a cushion.
- Missing everything: the cue ball touches no object ball.
- Double hit or push shot: the tip stays on or hits the cue ball twice.
- Touching balls with your hand, clothing or cue, or moving the cue ball outside ball in hand.
- No foot on the floor while shooting (WPA 3.4).
One difference: knocking an object ball off the table is a foul under WPA (3.5), but under APA it is not a foul; the ball is spotted on the foot spot.
12. Is there a three-foul rule in 8-ball?
No. The WPA rules (3.13) say that some games, 8-ball among them, do not use the three-consecutive-foul rule. The CSI 8-ball rules don't include one, and neither do the APA game rules. The three-foul loss belongs to 9-ball and 10-ball.
13. Are jump shots legal?
Yes, if you jump the ball by striking down on it so it bounces off the cloth (WPA 2.9). Scooping, digging the tip under the cue ball to lift it, is not a legal jump: it is a foul in APA and CSI when done on purpose, and WPA treats it as a miscue, with intentional miscues penalized as unsportsmanlike conduct.
WPA lets you switch to a jump cue during a match (1.4). The CSI rules define jump cues and jump-break cues as equipment; check the event's rules for any limits. APA allows them only in its Masters divisions, and you may not take your regular cue apart to make it shorter for a jump shot.
14. What if you pocket your opponent's ball?
If you hit one of your own balls first, it is not a foul. If one of your balls also went in legally, you keep shooting; if only your opponent's ball dropped, your turn ends. Either way the pocketed ball stays down; it is not spotted (APA "Combination Shots", CSI 2-7, WPA 4.7).
Playing in a bar? Agree on three things first
House rules are where most arguments come from. Before the break, settle:
- Is the 8 on the break a win? (APA says yes; WPA and CSI say re-spot or re-rack.)
- Is scratching on the 8 a loss if the 8 doesn't drop? (APA says yes; WPA and CSI say it's just ball in hand.)
- Do you call every shot, or only the 8?
Get those three straight and you have headed off most of the disputes in this article.

What is a scratch in pool?
The cue ball going into a pocket or off the table. It's a foul and gives your opponent ball in hand; if it happens on the same shot as the 8 going in, you lose.
What does ball in hand mean?
After a foul, the incoming player may pick up the cue ball and place it anywhere on the table before shooting. After a foul on the break, WPA and APA restrict it to behind the head string.
Can you win on the break in 8-ball?
Under APA rules, yes, if the 8 goes in and you don't scratch. Under WPA and CSI rules, no: the 8 is spotted or the balls are re-racked.
What are the official 8-ball rules?
There isn't one set. The WPA rules are the world standard for tournaments; leagues such as the APA and BCAPL (CSI) use their own. Check which ones your league or event uses.
