Crucible curse

The "Crucible curse" (also known as "The curse of the Crucible") is a quip in professional snooker, referring to the fact that no first-time winner of the World Snooker Championship has retained the title since the tournament moved to Sheffield's Crucible Theatre in 1977. Beginning with the 1979 champion Terry Griffiths, who lost in the second round of the 1980 event, 19 first-time world champions have failed to defend their titles, although Joe Johnson and Ken Doherty made it to the final the year after their maiden victories. Most recently, the 2023 champion Luca Brecel lost in the first round of the 2024 World Snooker Championship. Kyren Wilson, winner of the 2024 event, is yet to attempt to break the Crucible curse.

Several world champions successfully defended their first title in the pre-Crucible era; the last to do so was John Pulman in 1964.

The curse
The first-time world champions listed below all experienced the "Crucible curse", as they did not successfully defend their title at the following year's World Championship.

Of the 19 players to have won their first world title at the Crucible Theatre, seven lost in their first match as defending champion: Terry Griffiths in 1980, Steve Davis in 1982, Dennis Taylor in 1986, Graeme Dott in 2007, Neil Robertson in 2011, Stuart Bingham in 2016 and Luca Brecel in 2024. Only two of the 19 were able to reach the final as defending champions: Joe Johnson in 1987 and Ken Doherty in 1998. Johnson came closest to breaking the curse, getting within four frames of retaining his crown, while Doherty came within six.

Four players have won consecutive world titles at the Crucible (having already won the championship previously): Steve Davis (1983–1984 and 1987–1989), Stephen Hendry (1992–1996), Ronnie O'Sullivan (2012–2013), and Mark Selby (2016–2017).

Pre-Crucible
Out of all the first-time world snooker champions, only three retained their title at the next World Championship: Joe Davis in 1928, his brother Fred Davis in 1949, and John Pulman at his first challenge match in 1964. No player in the modern era (post-1969) has successfully defended a first world title, even before the tournament was staged at the Crucible Theatre.

John Spencer, Ray Reardon and Alex Higgins won the World Championship for the first time before the event was moved to the Crucible in 1977, and failed to retain the title the following year (although this could not be attributed to the "Crucible curse"). All three players subsequently won the championship at the Crucible for the first time, but then fell to the "curse" when they failed to successfully defend the title the following year.
