Please write all the applicable mahjong specific rules

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.

Or even post a video on how to play. The game doesn't offer any real instructions to learn this.
