  7. All players and staff must be treated with respect. Instructions from referees and the host are to be followed. Decisions labelled as final are not to be objected.

  1. Players will have 2 minutes to pick and ban a beatmap, and 2 minutes to get ready. If a player takes more time than allowed, the procedures adopted will be as follows:
    • For map bans, the player forfeits the ban.
    • For map picks, a random map will be chosen from the mappool using !roll X, where X is the number of maps that were neither picked nor banned, excluding the tiebreaker.
    • For a ready timer, the referee will use !mp start 10 command.
  2. Each player will receive one tactical timeout of 2 minutes, to be used as extra time to pick or ban a beatmap. The tactical timeout is optional.

    • The winner of the !roll chooses whether to pick first or ban first.
    • Each player may ban one beatmap from the mappool. These beatmaps cannot be picked by any player for the entire duration of the match.
    • Both players will alternate picking a beatmap from the mappool.
  5. In the case of a tie, the beatmap will be rematched, but not more than twice.
  6. Players are allowed to rematch if any player disconnects early on during a beatmap. Send a message as soon as poosible in the match room chat to notify the referee to restart the match.
    • The match may only be aborted before 30 seconds or 1/4 of the beatmap has elapsed, whichever comes first.
    • The same mods and beatmap must be used when the match restarts.
    • Please make sure to resolve any technical issues before restarting the match.
  7. Unexpected incidents will be handled by the host. Referees may allow higher tolerance depending on the given circumstances. This is up to their discretion.
  8. The host may request liveplays or recordings of individual players or teams at any point.
  9. The host reserves the right to modify these rules at any moment. Any such changes will be announced in advance.
