  2. The maps for each round will be announced by the mapset selector in advance on the Sunday before the actual matches take place. Only these will be used during the respective matches.
    • One map will be given as a tiebreaker map. This map will only be played in case of a tie.
    • All maps are in a FreeMod bracket.
  3. Match schedule will be settled by the Tournament Management (see below).
  4. If no staff or referee is available, the match will be postponed.
  5. Failed players' scores do not get added to the team score.

  6. Use of the Visual Settings options are allowed.
  7. If the game ends in a draw, the game will be nullified.
  8. If a player disconnects, they get treated as if they failed the map.

    • Have higher ∑{(total score difference) / (maximum score)}.
