Ruleset

Our standard ruleset is based on the Mahjong Soul ranked ruleset, with modifications for fairness and in-person gameplay.

Major Modifications

These are changes that commonly affect gameplay.

Uma

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

Chonbo/Dead Hand

We follow WRC’s definition of chonbo and dead hand, except with the following changes:

  1. chonbo penalty is always -10 to the player’s score.
  2. an empty win call without revealing the hand results in a dead hand, NOT chonbo.

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.

Minor Modifications

These are very specific changes that rarely affect gameplay.

  • Renhou is a 7-han yaku.

Clarificatinos

  • 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).
