Ruleset

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

Major Modifications

These are the changes that commonly affect gameplay.

• Abortive draws are off.
• Kiriage Mangan is on.
• Agariyame and tenpaiyame are off.
• Leftover riichi bets are lost.
• South/West Extension is off (game ends upon rotating out of East 4/South 4).

We follow the WRC 2022 Ruleset for any rules specific to in-person play, including the definition of chonbo and dead hand, with the following exceptions:

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.

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.

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).
