The
Swiss Stage of the 2025
League of Legends World Championship runs from October 15 to 25. Sixteen teams are participating in this first phase of the Main Event. They will compete in up to five consecutive rounds, facing different opponents each time with no chance of a rematch. Teams that secure three victories will advance to the Knockout Stage, while those suffering three losses will be eliminated.
For the first round, seed 1 will face seed 3 while seed 2 will face each other, with regional protection. After that, each round matches teams with identical win-loss records. In total, eight teams will move on, and eight will be eliminated. Qualification and elimination matches are best-of-three (BO3), while all other matches are best-of-one (BO1).
