In each leg, the 24 players are divided into 8 groups having 3 players each. The players in a particular group play in round-robin where the one who's on top moves into the quarter finals.
From the group stages to the quarter finals, the matchers are race to 9. The semis and final matches are race to 11. Also in the semi-finals and finals, a player must win by at least 2 racks. This means he can 11–9. If the other player manages to makes 10-10, the match goes into extra racks, one of them will have to make 12-10 or 13–11 to win. The maximum extension is up to 13, so it is also a win for a player to score 13–12.
A shot clock of 45 seconds is used with one extension for each player per rack. Failing to shoot within the clock will fine the player US$50.
The "alternating break " rule is enforced.
Starting in 2008, the final will be a race to 11 racks affair and the "at least 2 racks to win" rule has been scrapped.
