The Grand Slam of Darts is a 48-player tournament (16 more players than 2025), with various qualification routes to get there.
The seeded players consist of the top-16 players, who are each assigned to a separate group, and then have two additional players assigned to their group in the event's draw (one player from pool #2 and #3, with #2 having higher-ranked qualifiers than #3).
The first four days of the tournament (Nov. 14 – 17) will be purely group stage games, as each player will play the other two players in their group (round-robin format). These games will be played to best-of-9 legs.
The winner of each group will advance to the last 16. If there were to be a three-player tie, it would be determined by leg difference and then legs won, legs won against throw, tournament average and lastly a nine-dart shootout.
The knockout stage (last 16) will begin on Nov. 18. The first round of the knockout stage is played to best-of-19 legs.
The final three rounds (quarterfinals, semifinals & final) of the tournament will take place from Nov. 18 – 22 and will all be played to best-of-31 legs.
