In snooker, a century break is a break of 100 points or more, compiled in one visit to the table. A century break requires potting at least 25 consecutive balls, and the ability to score centuries is regarded as a mark of the highest skill in snooker. Ronnie O'Sullivan has described a player's first century break as the "ultimate milestone for any snooker player".
