If a tournament has more than 25 players (up to a maximum of 150), multiple small tournaments are formed. The winners (and potentially runner-ups) of the Final Tables move to a Grand Final of 4 to 6 players. Seating at the Grand Final is completely randomised.
A new small tournament is added for every part of 25 players.
A tournament has 57 participants. There are two sets of 25 and one part of a 25, so we end up with three small tournaments.
Two of the tournaments have tables of 5, 4, 4, and 4, and the third has four tables of 4 players.
After the 3 rounds, the five best players of each tournament run their finals, according to the standard rules.
We then need to create a finals tables of 4 to 6 players. With three groups, we are in a multiple of 6, meaning we need two players from each finals to move on to the Grand Finals. This is done in the same way as for the Casual format (Game Winner and the best runner-up).
