How A 147 Break Is Built

1

Clear all 15 reds with black15 reds, each followed by the black (worth 7) and re-spotted — 15 × 8 = 120 points.

2

Pot the yellow2 points — running total 122.

3

Pot the green3 points — running total 125.

4

Pot the brown4 points — running total 129.

Pot the blue5 points — running total 134.

6

Pot the pink, then the black to finish6 + 7 = 13 points — final total 147, the maximum break.

What Is A Snooker Break?

A break is the running score a player builds during one uninterrupted visit to the table, potting balls in the correct sequence (red, colour, red, colour...) until they miss, foul, or clear the table. The break ends there, and their points are added to the frame score.

How Does The Maximum-Break Formula Work?

Each red still on the table represents a potential 8-point swing (1 for the red, 7 for the black nominated after it), and once every red is cleared, the six colours are worth a fixed 27 points potted once each in ascending order. Multiplying reds remaining by 8 and adding 27 gives the theoretical ceiling for that position — add whatever's already been scored in the break to get the maximum possible total.

Who Uses A Maximum-Break Calculation?

Commentators use it constantly during professional matches to tell viewers whether a 147 or a century is still mathematically possible. Players and coaches use it to judge risk during a break — whether it's worth attempting a low-percentage pot to keep a maximum alive, or safer to consolidate the frame lead instead.

Common Mistakes When Working Out A Maximum Break

The most common mistakes are forgetting that only black (not every colour) is assumed for the maximum-break calculation, confusing "points already scored in this break" with the overall frame score, and not accounting for the fixed 27-point colours phase that only happens once, right at the end.

What Happens Next?

If a century or maximum is still mathematically possible, the outcome still depends on the player actually potting every remaining ball — use the scenario table above to see how the ceiling drops with every red that's missed or safety-played, and the timeline to see exactly how a maximum 147 is built shot by shot.

Important Considerations

This calculator gives the mathematical ceiling only — it does not predict whether a player will actually achieve it, and it does not model fouls, safety exchanges, re-spotted colours mid-break, or the rare free-ball exception that can raise the ceiling above 147. It's a planning and commentary reference tool, not a live match scorer or a prediction of outcome.

Frequently Asked Questions

What is the maximum possible break in snooker?

147 points — achieved by potting all 15 reds each followed by the black (15 × 8 = 120 points), then potting all six colours in ascending order (yellow, green, brown, blue, pink, black) for a further 27 points. This is recognised by the WPBSA, the sport's official governing body, as the maximum break under standard rules.

How do you calculate the maximum possible break from a position?

Multiply the number of reds still on the table by 8 (each red is worth 1 point, and the black that follows it is worth 7, so a red-black pair is worth 8), then add 27 for the fixed value of clearing all six colours at the end. Add that total to whatever has already been scored in the current break to get the maximum possible break from that position.

Why is a red-and-black pair worth 8 points?

Because the maximum-value strategy is to nominate black (worth 7 points) after every red (worth 1 point) for as long as reds remain on the table, since black is the highest-value colour. 1 + 7 = 8 points per red potted this way.

Why are the colours worth exactly 27 points at the end?

Once all 15 reds are cleared, the six colours are potted once each, in a fixed ascending order: yellow (2), green (3), brown (4), blue (5), pink (6), and black (7). Added together: 2 + 3 + 4 + 5 + 6 + 7 = 27.

What counts as a "century break"?

Any break of 100 points or more. It's a widely recognised milestone in snooker — professional players' century-break counts are tracked as a career statistic, and many amateur players treat their first century as a significant achievement.

Can a break exceed 147 points?

Under standard rules, no — 147 is the maximum. The one recognised exception is a "free ball": if a player is fouled while snookered and no red is available for a direct shot, the referee can award a free ball, effectively creating an extra scoring opportunity before any red has been potted. This can raise the theoretical ceiling to 155, but it has only happened twice in recorded professional competition, so this calculator models the standard 147-point case rather than the rare free-ball exception.

How many reds do I need left to still make a century?

It depends on how many points you've already scored in this break. This calculator works it out for you: it takes the points still needed to reach 100, subtracts the fixed 27 points available from the colours phase, and divides what's left by 8 (rounding up) to give the minimum number of reds you'd need to pot, with the black, to guarantee reaching a century.

What's the difference between a break and a frame?

A break is the running score a player builds in one uninterrupted visit to the table (it ends when they miss, foul, or the frame finishes). A frame is a complete game, made up of one or more breaks from both players, won by whoever has more points when all the reds and colours are gone (or by concession/other rules in specific situations). This calculator is about break potential, not the overall frame score.

Does a foul end a break?

Yes — a break ends when the player misses a shot, commits a foul, or the frame situation changes turn (for example, running out of balls). The points scored in that break are still added to the player's frame total, but the running break count resets to zero for their next visit to the table.

What order are the colours potted in during normal play, not the final sequence?

During the reds phase, a player alternates: pot a red, then pot any one colour of their choice (which is re-spotted afterwards so it stays in play), then another red, and so on. Only once every red has been potted do the colours get potted once each, in the fixed ascending order (yellow, green, brown, blue, pink, black) without being re-spotted.

Why does this calculator show "Check Your Numbers" for some inputs?

Because the combination of reds remaining and points already scored you entered would produce a maximum possible break over 147 — which isn't achievable under standard rules in a single break. Double-check your reds remaining count and your current break score; if you're calculating a frame total across multiple breaks rather than one continuous break, this calculator isn't the right tool for that.

Is 15 reds always the starting point?

Yes, under the standard rules of snooker there are always 15 reds racked at the start of a frame. If reds have already been potted in this visit or an earlier one in the same frame, enter however many are still left on the table now, not 15.

Do all colours count for the same points during the reds phase?

No — a colour potted between reds is worth its own individual value (yellow 2, green 3, brown 4, blue 5, pink 6, black 7), whichever the player chooses to nominate and successfully pot. This calculator's maximum figure assumes black (the highest value) is chosen every time, since that gives the true ceiling — a real player might choose a lower-value, safer colour instead, which would reduce their actual maximum below this calculator's figure.

Has anyone made more than one maximum 147 break?

Several professional players have made multiple official maximum breaks in their careers — the WPBSA maintains the full historical record. This calculator doesn't track individual player records; it's a general-purpose maximum-break planning tool for any position.

Can I use this for six-red snooker or other variants?

No — this calculator is built for standard 15-red snooker. Six-red snooker and other variants use different ball counts and scoring structures, so the 8r+27 formula and the 147 maximum do not apply directly.
