The first World Snooker Championship was held in 1927, and since 1977 it has been played at the Crucible Theatre in Sheffield. In the modern era, the best record is that of Stephen Hendry, who has won the title seven times, while Steve Davis and Ray Reardon have both won six times. The reigning champion is first-timer Mark Selby.
- The all-time greatest number of wins is fifteen by Joe Davis. This was in an era when there were few professional players and far fewer matches required to win.
- The first 147 maximum break in the championship was achieved by Cliff Thorburn in 1983. Stephen Hendry (1995, 2009, 2012) and Ronnie O’Sullivan (1997, 2003, 2008) are the only players to achieve 147 maximum more than once. Jimmy White (1992), Mark Williams (2005) and Ali Carter (2008) have also made a 147 maximum break at the final stages of the World Championship.
- Ronnie O’Sullivan’s 147 break in 1997 was the fastest ever in the professional game, at only 5 minutes 20 seconds.
- The 2008 event was the first ranking tournament to produce two 147 breaks in the latter stages. They were scored by Ronnie O’Sullivan and Ali Carter.
- Cliff Thorburn’s victory over Terry Griffiths in the 1983 championship was completed at 3:51 am, the latest ever finish for a match at the Crucible. The 2007 final between John Higgins and Mark Selby was completed at 00:54 am, the latest finish for a final.
- The longest ever frame at the World Snooker Championship- 74 minutes 58 seconds, and was played between Stephen Maguire and Mark King in 2009.
- Fergal O’Brien is the only player to score a century in his first frame at The Crucible, which he did in 1994.
- Luca Brecel was the youngest ever player to reach the World Championship in 2012 at the age of 17 years and 35 days. He was also the youngest player to score a century break (116).
- Stephen Hendry was the youngest ever champion when he won in 1990 at the age of 21 years and 106 days.
- Jimmy white has reached six finals, but has never won. The closest he came was 17–18 in 1994 against Stephen Hendry, on his 32nd birthday.
- There have only ever been four champions from outside the UK: Horace Lindrum of Australia in 1952; Cliff Thorburn of Canada in 1980; Ken Doherty of the Republic of Ireland in 1997 and Neil Robertson of Australia in 2010.
- Surprise winners at The Crucible include Joe Johnson and Shaun Murphy, who won in 1986 and 2005 respectively against odds of 150–1 each, and Terry Griffiths, whose 1979 victory came in only his second professional tournament.
- Ken Doherty is the only player to have won the world title at junior, amateur and professional level.
- Stephen Hendry holds the record for the longest unbeaten run at The Crucible Theatre. He won the Championship every year between 1992 and 1996, and continued unbeaten until the 1997 final.
- In the 2009 event, Stephen Hendry won his 1000th frame at The Crucible Theatre, against Ding Junhui.
- Since the tournament has been held at The Crucible in 1977 only three players have successfully defended the world title: Steve Davis in 1984, 1988 and 1989, Stephen Hendry from 1993 to 1996 and Ronnie O’Sullivan in 2013. No player has successfully defended his first title at The Crucible, an anomaly often referred to as the Crucible curse.
