Championship League

The Championship League (formerly known as the Premier League), currently referred to as the Ladbrokes Championship League for sponsorship purposes, is a professional invitational league-format snooker event which runs every season from late-January to mid-April. Ten players compete in the tournament, with six players qualifying through the Order of Merit, and four wildcard entrants chosen by the WPBSA and the television channel (formerly Sky, now ITV). Ronnie O'Sullivan has dominated the event, winning it a record 12 times. The only other player to have won the event is Australia's Neil Robertson, who won titles in 2011 and 2013.

The players play each other once in a 6-frame match. Unlike other snooker events, a draw is a possible result in the league. 2 points are awarded for a victory, and 1 for a draw. At the end of the leagues phase, the top 4 players in the league table go forward to the best of 7 semi-finals stage. The final is then played over best of 9 frames.

Each week, the round robin games would be played in alternate locations around the United Kingdom and the Republic of Ireland. The play-offs (semi finals and final), were played in one location every season. Prize money for the tournament has increased dramatically, with the winner in 2001 receiving £30,000, and the winner in 2013 receiving £175,000. This was increased again to £200,000 for the winner in 2016.

Ronnie O'Sullivan is the reigning champion.
