Pool Rules & Strategy
What Is a Scratch in Pool?
What counts as a scratch, when it means ball-in-hand or loss of game, how break scratches differβand how to keep the cue ball out of trouble.
In pool, a scratch is more than a minor mistake. It is a cue-ball foul that can give your opponent ball-in-hand, surrender control of the table orβunder certain 8-ball rulesβend the game immediately.
The confusing part is that βscratchβ is often used casually to describe several different fouls. Official rulebooks are more precise. A true scratch normally means the cue ball was pocketed or left the playing surface, while wrong-ball contact, no contact and failure to drive a ball to a cushion are separate fouls.
The Definition
What Counts as a Scratch?
A scratch occurs when the cue ball is pocketed or driven off the table. In most organized rule systems, this is a foul and the incoming player receives some form of ball-in-hand.
A cue ball is also considered off the table when it comes to rest somewhere other than the playing surfaceβfor example, on the floor, a rail or another piece of equipment.
Scratch versus foul: Every scratch is a foul, but not every foul is a scratch. Hitting the wrong ball first, failing to contact an object ball, making a double hit or failing to drive a ball to a cushion after contact may all be fouls even though the cue ball remains on the table.
Common Situations
Four Cue-Ball Fouls Players Call Scratches
Situation 01
Gameplay Scratch
The cue ball enters a pocket or leaves the table during ordinary play. Under WPA, CSI/BCAPL and APA rules, the usual penalty is ball-in-hand for the incoming player.
Situation 02
Break Scratch
The cue ball is pocketed or driven off the table during the opening break. It is not automatically a loss under WPA or CSI/BCAPL rules, but the allowed cue-ball placement differs by rule system.
Situation 03
8-Ball Scratch
The result depends on both the rulebook and whether the 8-ball was pocketed. Under APA rules, scratching while playing the 8-ball is a loss. WPA and CSI/BCAPL generally treat the shot as a standard foul if the 8-ball remains on the table.
Situation 04
βTable Scratchβ
This informal term usually means a foul without pocketing the cue ballβfor example, missing every object ball. It is technically a standard foul rather than a true scratch, but it normally awards ball-in-hand.
The Penalty
What Happens When You Scratch?
During normal play, the most common penalty is ball-in-hand. This allows the incoming player to pick up the cue ball and place it in a legal position before shooting.
Under most tournament systems, normal-play ball-in-hand can be used anywhere on the playing surface. Break scratches can be different: WPA and APA 8-ball rules restrict the incoming cue ball to behind the head string, while CSI/BCAPL awards ball-in-hand anywhere after a foul on an otherwise legal break.
House rules frequently differ. Some bars and recreational players use βkitchenβ rules for every scratch, requiring the cue ball to be placed behind the head string. Confirm the rules before the break rather than waiting for a disputed shot.
Official Rule Sets
Scratch Rules by Governing Body
| Scenario | WPA 8-Ball | CSI / BCAPL 8-Ball | APA 8-Ball |
|---|---|---|---|
| Normal-play cue-ball scratch | Ball-in-hand anywhere | Ball-in-hand anywhere | Ball-in-hand anywhere |
| Scratch on an otherwise legal break | Cue ball behind the head string | Ball-in-hand anywhere | Cue ball behind the head string |
| Scratch while shooting the 8-ball; 8-ball stays up | Ball-in-hand; game continues | Ball-in-hand; game continues | Loss of game for an actual cue-ball scratch |
| Cue ball and 8-ball pocketed on the same non-break shot | Loss of game | Loss of game | Loss of game |
| 8-ball pocketed on a legal break without a foul | Breaker chooses re-spot and continue or re-break | Breaker chooses re-spot and continue or re-break | Win for the breaker |
| 8-ball pocketed on the break with a cue-ball foul | Opponent chooses re-spot with cue ball behind the head string or re-break | Opponent chooses re-spot with ball-in-hand anywhere or re-break | Loss for the breaker |
| No legal object-ball contact | Ball-in-hand | Ball-in-hand | Ball-in-hand; missing the 8-ball is not itself a loss |

Important APA distinction: If a player scratches or sends the cue ball off the table while playing the 8-ball, the opponent wins. If the shooter simply misses the 8-ball without pocketing the cue ball, it is a table foul and the opponent receives ball-in-handβthe game does not end for that foul alone.
Opening Shot
Do You Lose If You Scratch on the Break?
Usually, no. Under WPA and CSI/BCAPL 8-ball rules, a cue-ball scratch on the break is a foul, but it is not an automatic loss. The game continues with the incoming player receiving the cue ball according to that rule system.
WPA places the incoming cue ball behind the head string following the applicable break foul. CSI/BCAPL gives the opponent ball-in-hand anywhere after a foul on an otherwise legal break. APA requires the cue ball to be played from behind the head string after an 8-ball break scratch.
The result changes if the 8-ball is also pocketed. WPA and CSI/BCAPL provide re-spotting or re-racking options. Under APA 8-ball rules, pocketing the 8-ball on the break is a win unless the breaker also fouls the cue ball, in which case it is a loss.
Understanding the penalty before you shoot is part of strategy. The same scratch can mean ball-in-hand, restricted placement or loss of game depending on the rulebook and the position of the 8-ball.
Cue-Ball Control
How to Avoid Scratches
Most scratches are not random. They follow predictable cue-ball paths. Before shooting, identify where the cue ball will travel after contacting the object ball and after reaching a cushion.
Principle 01
The 30-Degree Rule
On many cut shots, a naturally rolling cue ball leaves the collision along a path near 30 degrees from its original direction. The exact angle varies with cut fullness, speed and spin, so treat 30 degrees as a planning reference rather than a fixed law.
Principle 02
The 90-Degree Rule
On a true stun shot, the cue ball initially travels along the tangent lineβapproximately 90 degrees from the object ballβs path. Recognizing that line helps reveal side-pocket and corner-pocket scratches before they happen.
Technique 01
Stop Shot
On a straight, full-ball hit, a cue ball sliding without forward or backward rotation can stop at impact. Practicing stop shots builds speed control and prevents the cue ball from following the object ball into the same pocket.
Technique 02
Draw and Follow
Draw shortens or reverses the cue ballβs forward path after contact, while follow lengthens it. Use these deliberately to move the cue ball away from a natural scratch line instead of adding spin without a specific destination.
Use this pre-shot scratch checklist
- Trace the natural path: Imagine where the cue ball travels without added spin.
- Check every nearby pocket: Include pockets reached after one or more cushions.
- Choose the simplest correction: Adjust the cut angle, speed or vertical spin before reaching for sidespin.
- Control speed: A cue ball that reaches a dangerous pocket slowly can still scratch.
- Accept a longer next shot: Safe position is often better than perfect position with a narrow margin for error.
Advanced Strategy
Intentional Fouls Are Rule-Specific
Advanced players sometimes accept an intentional foul when every legal option produces a worse result. This is especially common in games such as One Pocket, where the foul penalty and ball-spotting rules can make a controlled foul preferable to leaving an easy scoring opportunity.
In rotation games such as 9-ball, an intentional foul is much riskier because it normally gives the opponent ball-in-hand. Many rotation formats also use a three-consecutive-fouls penalty, so both players must track the foul count carefully.
An intentional foul should therefore be treated as a calculated, rule-specific decisionβnot as a general scratch-prevention technique.
Quick Answers
Frequently Asked Questions
Is every foul a scratch?
No. A scratch normally involves pocketing the cue ball or sending it off the table. Wrong-ball contact, no contact, double hits and no-rail fouls are separate fouls even though players sometimes call them table scratches.
Do you lose if you scratch on the break?
Usually not. WPA, CSI/BCAPL and APA treat an ordinary 8-ball break scratch as a foul rather than an automatic loss. The cue-ball placement and the result of pocketing the 8-ball at the same time differ by rule system.
Is a scratch on the 8-ball always a loss?
No. Under WPA and CSI/BCAPL rules, fouling while shooting the 8-ball is generally ball-in-hand if the 8-ball remains on the table. Under APA rules, an actual cue-ball scratch or cue ball off the table while playing the 8-ball is a loss.
Where can the opponent place the cue ball after a scratch?
Normal-play scratches generally award ball-in-hand anywhere. Break scratches may restrict the cue ball to behind the head string, depending on the rulebook.
What is the kitchen in pool?
The kitchen is the area between the head rail and the head string. Some break-scratch and house rules require the cue ball to be placed within this area.
What happens if the cue ball jumps off the table?
The cue ball is considered off the playing surface, resulting in a foul. The incoming player receives ball-in-hand according to the applicable game and rule system.
Make the Cue Ball Predictable
Scratch prevention begins with recognizing the natural cue-ball path. Learn the tangent line, understand rolling-ball angles, control speed and confirm the rules before the match begins.
When you give the cue ball the same attention as the object ball, scratches stop feeling random. They become visible risks that can be planned around.
