n. (context snooker English) A consecutive score of 100 or more points in one visit to the table in a frame of snooker
In snooker, a century break (sometimes referred to as a ton) is a score of 100 points or more within one at the table without missing a shot, and requires potting of at least 24 consecutive balls. The ability to score century 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 824 century breaks.
