Snooker Fouls Explained: Penalties and the 4-Point Rule

Every foul in snooker hands your opponent points — a minimum of four, or the value of the ball involved if that’s higher. Get the ball values right and you can read any foul: four for most, but five off the blue, six off the pink, seven off the black. This is the full list of common fouls, what each one costs, and the free-ball rule that can follow.

Fouls aren’t a footnote in snooker; they’re often how frames are decided. In a tight safety exchange, a single careless in-off can swing the result.

The four-point rule

The core penalty is simple: a foul awards the opponent at least four points, or the value of the ball involved if that value is higher than four. Only one penalty is applied per shot — the highest value involved.

Foul	Points to opponent
Miss all balls / hit a red or low colour wrongly	4
Foul involving the blue	5
Foul involving the pink	6
Foul involving the black	7

So the maximum single foul is seven (the black), and the minimum is always four, even if the ball involved is a red or the yellow, which are worth less. If you need the ball values themselves, our snooker ball values chart lists all seven.

The common fouls

Most fouls fall into a handful of familiar situations:

• Missing all balls — the cue ball fails to hit any ball: 4 points.
• In-off — potting the cue ball; the white is then placed in the D for the opponent.
• Hitting the wrong ball first — striking a colour when you’re on a red, or the wrong colour in the clearance: 4, or that ball’s value if higher.
• Potting the wrong ball — sinking a ball you weren’t on.
• Ball off the table — jumping a ball off the playing surface (jump shots are illegal in snooker).
• Touch/push fouls — touching a ball with anything but the cue tip, or pushing the cue ball.

Because these all interact with the ball values, the black is the most expensive ball to foul on and the reds and yellow the cheapest — though the four-point floor means even a foul on a red costs four. For how those points fit into the wider scoreboard, see our how snooker scoring works guide.

The incoming player’s choice

After a foul, the player coming to the table gets a choice: play the balls where they lie, or ask the fouling player to play again. If a nasty snooker has been left, making your opponent tackle it themselves is often smarter than taking the shot on. That decision is a real tactical layer — the foul points are only half the damage.

The free ball

When a foul leaves the incoming player snookered — unable to hit both edges of the ball they’re on in a straight line — the referee awards a free ball. The player may nominate any ball to act as the one they’re on. Nominate it as a red (while reds remain), pot it, and you score 1 and carry on with a colour.

The free ball is the one rule that can push a break beyond the usual 147 maximum, because it effectively adds an extra “red” at the start of a frame — the route to a theoretical 155.

The miss rule

The miss rule exists to keep players honest. If a player fails to hit the ball they’re on and the referee judges they didn’t make a genuine attempt, it’s a foul and a miss: the opponent gets the foul points and can ask for the balls to be replaced and the player to try again. It stops a player from just deliberately fouling to wriggle out of a hard snooker.

Avoiding cheap points

At every level, the difference between winning and losing close frames is often just discipline — not gifting your opponent four, five or seven points on a lazy shot. If you’re learning, our how to play snooker guide covers the setup and first visit, and snooker rules explained puts the fouls in the context of the full ruleset.

The short version: every foul gives the opponent at least four points (up to seven off the black), the common ones are misses, in-offs, wrong-ball hits and balls off the table, the incoming player can make you play again, and a foul that snookers them may hand over a free ball.
