Century break

In snooker, a century break (sometimes referred to as a ton) is a score of 100 points or more within one visit at the table without missing a shot, and requires potting of at least 24 consecutive balls. The ability to score century breaks is regarded as a mark of the highest skill in snooker, while the first career century has been described by Ronnie O'Sullivan as the "ultimate milestone for any snooker player".

Over 20,000 century breaks have been recorded by snooker players throughout professional tournaments. In 2014, Neil Robertson became the first person to have scored over 100 century frames throughout a single season, a threshold that only some 50 other players had surpassed throughout their entire careers. Ronnie O'Sullivan holds the record for the most career centuries, with 802 century breaks.

Rules

A century break is a score of 100 points or more within one visit at the table, without missing a shot. The player does this by potting red balls and coloured balls alternately, and when no reds are left, potting the coloured balls in order of their increasing value. Because a break is defined as series of consecutive pots by a player during a single frame, scoring 100 points over the course of a whole frame does not necessary constitute a century break, as it must be done on a single turn at the table. Points for a foul shot by the opponent do not count in a player's break.
