Hi

The mahjong pages do not treat of the specific rules of Riichi mahjong apllied or not to doman riichi, such as abortive hands, 2-Han hands etc.

Can you please update your rules to list the specific case please?
From what i could see

-Sucha riichi (4 richi) does not abort the game
-Same wind discard at 1st turn does abort the game
-No 2-han hand required when we reach 4 sticks
-PLayer can declare riichi even if he can't call a tsumo before the wall end
-agari yame applied (east player can end the match if he is 1st at south 4th.

Best regards,
D.
