Among yaku, some have menzen as a condition.

Yaku that are only possible when menzen: Riichi, Ippatsu, Menzenchin Tsumohou Pinfu, Iipeikou, Chiitoitsu Double Riichi, Ryanpeikou Kokushi Musou, Suuankou Chuuren Poutout, Tenhou, Chiihou

Within these, the conditions where you can only agari via tsumo are: "Suuankou with a wait that isn't tanki" "Tenhou" "Chiihou"

On the other hand, yaku that are possible after you've called tiles, but which lose han in that case (called kuisagari), as well as yaku where it doesn't matter if you've called tiles or not, are as shown here.

Yaku with kuisagari: Sanshoku Doujun, Ikkitsuukan Honchantaiyaochuu, Hon'itsu Junchantaiyaochuu, Chin'itsu

Yaku without kuisagari: Tan'yaochuu, Yakuhai, San'ankou Honroutou, Toitoihou, Sanshoku Doukou Sankantsu, Shousangen, Daisangen Tsuuiisou, Shousuushi, Daisuushi Ryuuiisou, Suukantsu, Chinroutou

San'ankou is counted if you have three ankou. It doesn't count minkou, so if you have a shanpon wait for your third ankou, this yaku will not be counted unless you get it by tsumo.

There's a rule that disallows tan'yaochuu with called tiles, but in "Saki" we use the rule that it is allowed.

Yaku are generally based on special patterns in your hand, but there are also yaku that are based not on tile combinations, but on special conditions, which are shown here.

Yaku based on special conditions: Rinshan Kaihou, Chankan Haitei Mouyue, Houtei Raoyui Ippatsu, Tenhou, Chiihou

Rinshan Kaihou should be familiar to people watching Saki

In addition to yaku, you can raise your number of han via "dora"! The dora is the tile one after the dorahyoujipai (dora indicator tile), and for each one you have in your hand, you get one extra han.

If you agari after declaring riichi, the tile beneath the dorahyoujipai is treated as an additional dorahyoujipai, and the dora it indicates is called "ura dora". Also, for each kan that is declared, one dorahyoujipai is added, and along with it an additional ura dora.

W... well, that's enough for now... There are certain limitations on which yaku can combine with each other, but it's tough to understand unless you explain each yaku individually... I'll do it... later

N, Nodo-chan I did well... right?

Yes, you did well.

Yes, you did well.

So leave the rest (this corner) to me
