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.

• Abortive draws are off.
• Kiriage Mangan is on.
• Agariyame and tenpaiyame are off.
• Leftover riichi bets are lost.

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 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.
