Championship League Snooker is the name given to two separate professional tournaments that have different status within the sport.
While each is promoted by Matchroom Sport, one is a ranking event that forms an integral part of the World Snooker Tour, while the other is a long-running invitational tournament.
Although they share the same name, the two competitions have different qualification criteria, formats, and objectives.
The two Championship League Snooker tournaments
Championship League Snooker currently exists in two forms:
Championship League Snooker (Invitational)
- First held in 2008 and won by Joe Perry
- Non-ranking event
- Invitation-only field
- Usually staged during the early months of the calendar year
- Promoted by Matchroom Sport
Championship League Snooker (Ranking)
- First held in 2020 and won by Kyren Wilson
- World ranking event
- Open to all professional tour players, with additional amateur entries if required
- Usually staged at the beginning of a new snooker season
- Promoted by Matchroom Sport
Although they operate independently, winners of both tournaments often earn invitations to the Champion of Champions.
Championship League Snooker (Ranking) format
The ranking version is played across three stages using a round-robin format throughout.
Stage One
The opening stage features 128 players divided into 32 groups of four. Each player meets the other three competitors in their group once.
- Win: 3 points
- Draw: 1 point
- Loss: 0 points
The group winner progresses to Stage Two. If players finish level on points, positions are decided by
- Frame difference
- Head-to-head result
- Highest break
Stage Two
The 32 group winners are divided into eight groups of four. The format remains unchanged, with each group played as a round robin.
The eight group winners advance to Stage Three.
Stage Three
The remaining eight players are split into two groups of four. Each group is played as a round robin.
The two group winners contest the tournament final.
Match format
All group matches are played as the best of four frames, allowing drawn matches. If a player wins 3-0, the fourth frame is not played.
The overall final is played as the best of five frames.
Championship League Snooker (Invitational) format
The invitational version follows a different structure that combines round-robin groups with knockout matches.
Seven groups of seven players are contested before the tournament concludes with the Winners’ Group.
Group stages
Each group consists of seven players. Every player competes against the other six in a round-robin format.
The top four players qualify for the knockout stage. Positions are determined by:
- Number of matches won
- Number of frames won
- Fewest frames lost
- Head-to-head result
Knockout stage
The top four players contest semi-finals and a final. The group winner advances directly to the Winners’ Group.
Four remaining players may continue in the tournament.
- The runner-up
- Both semi-finalists
- The player who finishes fifth
These players move forward to the next qualifying group. The sixth and seventh-placed players are eliminated.
Winners’ Group
The seven qualifying group winners contest the Winners’ Group using the same format.
The winner of the Winners’ Group is crowned champion.
All matches in the invitational tournament are played as the best of five frames.
Special 2020 edition
A second edition of the invitational event was staged in 2020 to fill a gap in the schedule created by the global COVID-19 pandemic.
This tournament featured 64 players. There were three round-robin stages of four players in each group. The final group was won by Luca Brecel.
Prize money
Both tournaments award prize money, although their structures differ.
The ranking event awards prize money based on finishing position in each group stage, with earnings counting towards the official world rankings.
The invitational tournament also offers performance bonuses, including rewards for group victories, frames won, and the highest break in each group.
A unique tournament structure
Championship League Snooker is unusual because two separate tournaments operate under the same name.
The ranking version provides an early opportunity for professionals to earn ranking points at the start of the season.
The invitational version offers a distinctive league-style competition that has remained part of the snooker calendar since 2008.
Despite sharing the same name, the ranking and invitational versions of Championship League Snooker should be regarded as separate tournaments rather than different editions of the same event.
