During the Group Stage, each group will play a double round robin of best-of-one series. The top two teams from each group advance to the final knockout bracket that ultimately determines the worlds winner.

The fourth team in each group will be determined during the play-in stage at worlds. The teams competing in the play-ins are split into two groups. The top teams from each group, after a series of best-of-one round robin matches, will advance directly to the Groups Stage. The 2nd through 4th place teams will play a knockout bracket, the two winners of which advance to Groups.

Worlds begins Oct. 5 with the play-in stage. The Main Event, which opens with Groups, begins Oct. 1
