The event's 12 teams are divided into two groups for an opening round that consists of a single round robin.

Round 2 of Play-In action, scheduled for Monday and Tuesday, will feature best-of-five matches. The third- and fourth-place team in each group will square off for the right to face the second-place team from the other group. The winners of each of the last two matches head to the Worlds' group stage, while all other teams will head home.

Thirteen teams are already through to the group stage: JD Gaming, Top Esports, EDward Gaming, Gen.G Esports, T1, DAMWON Gaming, Rogue, G2 Esports, Cloud9, 100 Thieves, CTBC Flying Oyster, GAM Esports and DRX.
