Ruleset

Our standard ruleset is based on the Mahjong Soul ranked ruleset, with modifications for fairness and in-person gameplay. See the final section for a comparison with the WRC 2025 Ruleset.

Major Modifications

These are the changes that commonly affect gameplay.

We follow the WRC 2025 Ruleset for any rules specific to in-person play, including the definition of chonbo and dead hand under the “lower penalties” variation, with the following exception:

  1. chonbo penalty is -10 to the player’s score, instead of -20.

Chonbo penalty is not enforced on beginners.

If we find that a player has intentionally committed chonbo, we will issue discretionary severe penalties, including banning the player from Queen City Riichi.

Uma

  • Yonma Hanchan: +16/+6/-6/-16
  • Yonma Tonpuu: +8/+3/-3/-8
  • Sanma Hanchan: +16/0/-16
  • Sanma Tonpuu: +8/0/-8

Minor Modifications

These are very specific changes that rarely affect gameplay.

  • Renhou is a 7-han yaku.

Clarifications

  • Nagashi Mangan payment will void tenpai payments. All other game progression stays unchanged (i.e., riichi sticks stay in the center, honba counter +1, dealership rotates if dealer is not tenpai).
