Ronnie O'Sullivan has scored the most century breaks in professional snooker tournaments.
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 at least 25 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 through a single season, a threshold that only some 60 other players had surpassed throughout their entire careers. Ronnie O'Sullivan holds the record for the most career centuries with more than 1000 century breaks; his 1000th century break was achieved in the final frame of the 2019 Players Championship in Preston.
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, where the coloured balls are repositioned on their starting locations. After repositioning the coloured ball paired to the last red on the table, the six coloured balls are potted 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 necessarily 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.
Under normal circumstances, the highest possible century in snooker is 147 (a "maximum break"), composed of 15 reds (one point each), 15 blacks (seven points each) and the six remaining colours; yellow, green, brown, blue, pink and black potted consecutively (two through seven points each for a total of 27). If for example only the least-valued colour (yellow, two points) would be used instead of the black ball, the break value would only be 72 points. This means that only a single century break is possible in a frame of snooker under a limited number of combinations, but it requires the potting of at least 25 consecutive balls (10 x (1 + 7) + 2 + 3 + 4 + 5 + 6 = 100). To score one, there must be at least ten reds on the table when the player comes to play since if there are only nine reds left, only 99 (= 9 × (1 + 7) + 27) points may be scored. An exception exists if the opponent fouls and leaves the incoming player snookered on all the remaining reds. In such a situation, the player can nominate one of the other colours as a red, known as a "free ball", which carries the same value as a red for just that shot, and therefore, a century break is still possible with only nine reds left.
Breaks above 147 are possible (up to 155) when an opponent fouls and leaves a free ball with all fifteen reds still remaining on the table, creating a situation identical to as if there were 16 red balls on the table. This has happened only once in professional competition, when Jamie Burnett made a 148 at the qualifying stage of the 2004 UK Championship.
List of players with 100 confirmed century breaks in professional competition
A "century of centuries" refers to a total of 100 breaks of at least 100 points each. Only 15 players had reached this milestone in professional snooker tournaments by December 2001. With an increase in the occurrence of centuries in the past decades, another 27 players achieved this landmark by October 2011, and by the end of the 2013/2014 season the total number of players reaching this threshold had grown to 52. Only Neil Robertson has achieved one hundred centuries in a single season, during 2013/2014. By the end of the 2018 English Open 66 players had reached 100 century breaks.[better source needed] The following players are reported to have passed 100 breaks and at least the given threshold above this.
Joe Davis compiled the first televised century break in 1962.
The record for most century breaks scored in official tournament play is held by Ronnie O'Sullivan with 1000 centuries. The record was previously held by Stephen Hendry who compiled 775 centuries over the course of his career.
The first (and so far, only) player to reach the 'century of centuries' (100 century breaks) mark during a single season is Neil Robertson in the 2013/2014 season on 30 April 2014 during his quarter final match against Judd Trump at the 2014 World Championship. In total, Robertson compiled 103 century breaks throughout the season.
The most centuries made by a player in a single match during a professional tournament is seven and the record is shared by Stephen Hendry, Ding Junhui and Judd Trump.
Hendry set the record during the final of the 1994 UK Championship. During this match, Hendry compiled six centuries in a span of eight frames.
Trump tied the record in the final at the 2019 World Championship. This equalled Ding's record at the Crucible Theatre and Hendry's record for a final. It also set a new record for a World Championship final at the Crucible, surpassing O'Sullivan's tally of six centuries during the final of the 2013 World Championship.
The most century breaks in a ranking event is eighteen centuries by Ding during the 2016 World Championship, compiling three during qualifying and a further fifteen at the Crucible Theatre during the main event. Hendry previously set a record of sixteen at the 2002 World Championship, which remains a televised, Crucible and venue record.
O'Sullivan has compiled more century breaks than any other player in the World Championship competition at the Crucible Theatre. He broke Hendry's record of 127 at the 2013 Championship, extending his total to 162 up to and including the 2017 Championship. John Higgins is the only other player besides Hendry and O'Sullivan to compile more than 100 centuries at the world championship in the Crucible era.
