Frequently Asked Questions

What is the maximum possible break in snooker?

The maximum break in snooker is 147 points, known as a 'maximum' or 'maximum break'. It is achieved by potting all 15 reds each followed by the black (15×8 = 120), then clearing all the colours in order: yellow (2), green (3), brown (4), blue (5), pink (6), black (7) = 27, for a total of 147.

How is 'Maximum Possible Break' calculated from remaining balls?

The calculator counts the reds left on the table, assumes each is followed by the black (worth 7 points), then adds the full colour sequence (yellow 2 + green 3 + brown 4 + blue 5 + pink 6 + black 7 = 27). So maximum break = (reds × 8) + 27. With all 15 reds, that equals 147.

How is the probability of achieving my target break estimated?

The probability is estimated using your pot success rate, break-building skill, table difficulty, and how ambitious your target is relative to the maximum possible break. A higher pot success rate and skill level with a lower table difficulty increases your probability, while a very ambitious target close to the maximum significantly reduces it.

What is an 'Expected Break Score'?

The expected break score is a realistic estimate of how many points you are likely to score in a single visit, given your pot success rate and skill level. It accounts for the probability that you will miss at some point during the break, weighted against the maximum you could theoretically make.

What does the Table Difficulty Factor represent?

The Table Difficulty Factor (1–10) reflects how challenging the positional play and pot angles are given the current layout of the balls. A score of 1 means the balls are well spread and easy to play; a score of 10 means the table is very congested or the angles are awkward, reducing your effective break potential.

What happens to the maximum break when reds are cleared?

Once all 15 reds and their nominated colours have been potted, the player must pot the six remaining colours in sequence: yellow, green, brown, blue, pink, black. The maximum score from this colour sequence alone is 27 points.

What is a century break in snooker?

A century break is when a player scores 100 or more points in a single visit to the table. It is considered a benchmark of high-level play. Professional players regularly make centuries, and the calculator can help you estimate the probability of achieving one given your current skill level.

How can I improve my break-building probability?

Improving your pot success rate through consistent practice is the most impactful factor. Developing positional play to control the cue ball after each pot, choosing safer colour selections when in position, and practising on tables of varying difficulties will all contribute to higher and more consistent breaks.
