Tsuuiisou, Chinroutou, and Ryuuiisou - Riichi Mahjong Guide

In this episode of Riichi Mahjong Guide, we cover three more yakuman: tsuuiisou, chinroutou, and ryuuiisou. All of these yakuman require you to use only six or seven specific types of tiles in your hand.
Feel free to leave any questions below.

Also, you can win tsuiisou with chiitoi for a yakuman (sometimes double) since there are 7 honors. More difficult but it exists.

In an old Mahjong game I have, there is also a variation called All Red (Hon itsu?). I never saw this as a Yakuman hand elsewhere in any other game, so maybe it's house rule. It's the same idea, except with the Red Dragon + the 1, 5, 7, 9 Sou. It's much harder to pull off though, because it ends up being a very specific SanAnKou/SuuAnKou.

I have heard of that. It's definitely a house rule.
