Tournament (Online)


  1. The rules used in the Riichi Montréal Open 2020 will be as close as possible to the WRC rules as permitted by Mahjong Soul tournament lobbies. See the #règles-rules channel on the Discord server for the complete list.
  2. The participants are expected to check in on both Saturday and Sunday on the tournament Discord server at the following time :
    12:00 (noon) Eastern Daylight Time;
    09:00 Pacific Time;
    18:00 Central European Time;
    03:00 Australia Eastern Daylight Time (it starts on October 4, on the first day of the tournament!)
    The games are expected to start one hour later.
  3. The tournament structure will be a staggered elimination model. Every two hanchans, there will be a round of eliminations. The ratios are as followed :
    1. After 2 hanchans : To be determined
    2. After 4 hanchans : To be determined
    3. After 6 hanchans (end of day 1) : To be determined
    4. After 8 hanchans : top 8 (semi-finals)
    5. After 10 hanchans : top 4 (finals)
  4. The scores will be halved for the remaining participants after the end of day 1.
  5. The last two (2) games on Sunday October 4 are final games. The scores for the finalists will be reset going into these final games.
  6. We expect good will and fair sportsmanship from all attendees, be they players or staff. Once a game is finished, we ask players to give their final scores in a timely fashion, and respect those that are still playing by joining the general voice chat lobby.

Etiquette rules

  • Respect the other players at every moment during the tournament
  • Swimsuit outfits (Beach Party series) are banned for this tournament. Use of one in a game will result in an automatic DQ. You can use the other outfits.
  • When streaming, use at least a 5 minute delay
  • Outside or tool-assisted help is forbidden. You are only allowed to use a yaku sheet and a points table.
  • When beginning a match, you commit to playing it through completion. Rage-quitting is not allowed and will result in a DQ.
  • You can use emotes, but do not delay the game unnecessarily.

Failure to respect the etiquette rules can lead to sanctions ranging from a warning to a DQ, to a ban from Montréal events.
