All 1v1 structures have matches played out as ‘best of 3’ games.
Organisers may also apply a time limit to each match (typically 1 hour).



For 1v1 tournaments of 5 or more players.

A Swiss tournament consists of a number of rounds to determine a winner or to determine which players advance to a single elimination knockout stage (optional).

Players are paired up randomly against other players with the same number of wins as them (or as close as possible if there are odd numbers), and only against players they haven’t already played against. When necessary, byes are decided randomly among the players with the fewest wins, but no player can have more than one bye in a tournament. A bye is treated as a win.



Any ties after the rounds of Swiss are first resolved based on who the players won and lost against. All of a player’s wins are tallied up based on the amount of wins their opponents ended on, and this gives them a score. For example, winning against someone who ended with 3 wins grants 3 points. If the numbers were odd, any bye counts as 0 points.

If there is still a tie, the following tiebreakers are checked in order (first resolved breaks it):

  • Whoever has the most game wins in the tournament.
  • Whoever has the highest win percentage.
  • If there is still a tie, it’s up to the event organisers to decide criteria.
    If there is time, a tiebreaker match can be played (potentially multiplayer, if necessary) where seating order is randomised..

Single Elimination

This is a structure for tournaments of 9 or more players, a single elimination stage may follow the rounds of Swiss (decided by the organisers). How many players advance to single elimination is determined by how many players are in the tournament, according to the table in this paragraph.

The single elimination stage is seeded based on the Swiss ratings, where the top seeded player is paired up against the lowest seed, etc. Additionally, the matches are distributed to delay the top player rematches for as long as possible.

Participants: Rounds of Swiss: Single Elimination:
5-8 3 None
9-16 4 Top 4
17-32 5 Top 4
33-64 6 Top 8
65-128 7 Top 8
129-256 8 Top 16
257-512 9 Top 16



This is a structure for 1v1 tournaments of 4 or more players. Players are distributed across the brackets either randomly or by seed.

If the amount of players is not a power of 2, all byes are handled in the first round, such that the tournament continues as normal after the first round has been completed. If it’s a seeded tournament, the players with the highest seeds get the byes, otherwise it’s randomly decided.



If the time for a round has run out before one or more matches have concluded, those matches will go down to tiebreakers. How these tiebreakers resolve depends on how far into the match the players are.

If they are in the first game of the match (current score is 0-0), it goes to sudden death (see below).

If they are between games 1 and 2 (current score is 1-0), the win goes to whoever won the first game.

If they are in the second game of the match (current score is 1-0), the game goes to sudden death (see below). If this results in a score of 1-1, game three starts with an immediate sudden death. If it instead results in a score of 2-0, whoever won is the winner.

If they are between games 2 and 3 (current score is 1-1), game three begins with an immediate sudden death.

If they are in the third game (current score is 1-1), it goes to sudden death (see below).

Sudden Death

Sudden death occurs when a current game in progress needs to finish for a winner to be declared. Each player in the game gets to take three more turns (including the one they are currently on). If the game still isn’t over at that point, the winner is whoever has the most health. If health is also tied, it keeps going until either health value changes (and the winner is whoever has the most).
