In snooker, the order of balls on the table dictates strategy, safety play, and scoring opportunities at every level of the game. Understanding how the colour sequence is restored after a foul or at the start of a frame helps players plan positional safeties and long potting lines.
From the opening break to the final black, the framework of reds and colours shapes each decision a player makes, turning the table into a chessboard of numbered opportunities.
| Phase | Legal Ball | Colour After Red | Sequence Example |
|---|---|---|---|
| Opening Frame | Red | Yellow (2) | Red, Yellow, Red, Yellow… |
| After Foul on Red | Red or Ball on Rule | Yellow (2) | Red, Yellow, Green (3), Brown (4)… |
| All Reds Potted | N/A | Yellow, Green, Brown, Blue, Pink, Black | 2 → 3 → 4 → 5 → 6 → 7 |
| Re-spotted Colours | Red | Nearest Spot Value | Red, Re-spotted Yellow, Red, Next Colour… |
| Free Ball Situation | Nominate Ball | Colour Value of Nominate | Nominate Red as Yellow, Pot Yellow, Next Legal Colour |
Sequence Rules During Regular Potting
Players must strike a red ball on every shot until all reds are off the table. Between reds, the next ball must be a colour in strict ascending order of value. Missing the correct colour results in a foul, handing frame control to the opponent with ball in hand.
Red then Yellow Logic
Because yellow is the lowest-value colour, it reappears immediately after each red. This pattern creates a predictable rhythm that intermediate players can use to map long potting paths around the table.
Post Red Colour Order
Once the last red is potted, colours must be potted in numerical order: yellow, green, brown, blue, pink, and finally black. This fixed sequence prevents confusion in high-pressure endgame scenarios and rewards precise positional play.
Handling Fouls and Re-spotted Colours
When a player commits a foul while a red is still on the table, the incoming player receives ball in hand and must nominate a red or play a free ball if available. After a foul on a colour, that colour is re-spotted on its designated location if it is not already occupied.
Re-spotting Mechanics
Each colour has a fixed re-spot location marked by small spots on the table. If the spot is occupied by another ball, the colour is placed on the highest-value available spot without disrupting existing order. This keeps the frame fair and maintains the intended difficulty of each stage.
Strategic Impact on Safety Play
Knowing that colours will return to the table encourages players to use tactical fouls only when necessary and to plan safeties that snooker the opponent on reds. Professional players often leave tricky reds paired with hidden colours to increase the complexity of escape routes.
Free Ball and Special Situations
When a player is snooker-ed behind the red ball, they may nominate a free ball, treating a nominated colour as a red for one shot. Potting the nominated colour scores the value of a red, and the player then continues by attempting the next legal colour in sequence. This rule adds a layer of tactical depth while preserving the core order of balls.
Using Free Ball Effectively
Choosing the right colour as a free ball can break up clusters, gain positional advantage, or set up a plant on a reds. Players weigh the risk of leaving a difficult colour re-spot against the reward of extra runs and reduced foul chances.
Key Takeaways for Players
- Always strike a red until all reds are potted, then follow the colour order strictly.
- After a foul on a colour, re-spot that colour on its designated spot whenever possible.
- Use the free ball option strategically to break safeties and create run opportunities.
- Plan positional paths with the next legal colour in mind to avoid snookers.
- Understand re-spot rules to anticipate table layout and reduce tactical surprises.
FAQ

What happens if I pot the wrong colour during my turn? You commit a foul, your opponent receives ball in hand, and the incorrectly potted ball stays down unless it is a colour that must be re-spotted according to the rules. Can I choose any colour after a foul on a red?
You must nominate a red or, if eligible, use the free ball option to nominate a colour as a red. You cannot pot any colour in any order at this stage.
Where are colours re-spotted if their spots are occupied?
They are placed on the highest-value available colour spot in numerical order, starting from yellow and moving toward black, without moving already settled balls.
Does the order change during tournament stages with multiple reds?
No, the fundamental red then colour sequence remains the same across all formats, ensuring consistent strategy from amateur to professional level.
