Ask a snooker fan for the perfect frame and you will hear one number, 147. It takes fifteen reds, each paired with a black, and a closing run up the colour ladder. A hush settles over the arena once a player sinks a second black early in a frame, and the commentary box starts whispering about it.
The number is perfect only as long as nobody fouls. Fans who like tracking scoring systems, odds and probabilities, the same way a player might browse a site such as x3bet casino to see how payouts are explained, tend to enjoy a quirk of this sport, because a second and higher ceiling sits behind the famous one. Its recipe needs only two ingredients and a rare piece of luck.
Where 147 Comes From
The arithmetic is simple, which is why it survives as a legend. A red is worth 1 point, and a black worth 7 is the most valuable ball a player can take after it. Repeating that pair fifteen times gives 120 points. Yellow through black, taken from the lowest value upward, supplies the remaining 27 points.
By the thirtieth pot, even a tiny drift in cue ball position can force a safety and finish the attempt. That is why the break is rare. A player must hold the table for roughly 36 consecutive pots with no safety shot, no miss and no awkward angle. Sheffield’s Crucible waited until 1983 for its first perfect frame, which came from Canadian Cliff Thorburn. The speed record is just over five minutes, set by a young O’Sullivan in Sheffield in 1997.

The Foul That Raises the Ceiling
Picture a safety exchange early in a frame where the cue ball is left tucked behind the pink, with a red in the way. The player cannot hit any ball on the table directly. If that opponent had also committed a foul on the shot, the referee declares a free ball. A free ball lets the incoming player nominate any colour as if it were a red. Pot the nominated blue, for example, and it counts as 1 point. The player then picks a colour as normal, takes the black for 7, and the sequence of fifteen reds is still waiting on the table. That extra pair adds 8 points, so the theoretical ceiling is 155.
Nobody has ever made it in professional play. The setup needs a foul at the exact moment all fifteen reds remain untouched, and it needs a snooker so tight the free ball is awarded. A player would then have to run the whole table afterwards.

A snooker table has a few more quirks that change the total for a single visit.
-
A foul by the opponent can add 4 to 7 penalty points to the player’s frame total, though not to the break.
-
When a frame ends level on points, one black goes back on its spot and the first pot wins.
-
Once the player misses, the running total resets and the next visit starts from zero.
Why the Distinction Matters
Statisticians at tournaments log these two numbers in separate columns, and the logic behind that split is worth a closer look.
A Break Is a Visit, Not a Frame
A break counts only what a player scores during one uninterrupted turn. Four points handed over after a miss go onto the frame total, and the scorer never adds them to the visit. Someone can take a frame by a huge margin through repeated opponent fouls while their best visit stays in the sixties.
That separation is what keeps the 147 meaningful. Only balls potted by the player’s own cue count, so a 147 stays a personal achievement.
Why 155 Stays Theoretical
Governing bodies recognise 147 as the official maximum, even while accepting that 155 is mathematically possible. The reason is practical. A free ball rarely arrives at the moment when all fifteen reds are still on the table, and the opponent who commits the foul would need to leave the cue ball locked behind a ball in the pack.
A theoretical figure has a quiet value of its own. It reminds players and spectators that a rulebook leaves more room than its most famous number suggests, and that the perfect frame depends as much on the opponent’s choices as on the cue.
