And next is!It looks like the yaku introductions are over now.Tenhou: When the oya's tiles from the haipai are something like belowWhat did you say!?This is only my second appearance!It looks like they were just about done last time.The explanations of the basics are done, too, so about all that's left is local rules.Summary of what's happenedChuuren is such a rarely-seen yaku that there's a rumor that if you agari with it, you'll use up all your luck and die.9-way waitThe first yaku we will introduce is this, which is quite fitting for a celebrity like me!
"Chuuren Poutou"!
This is when, in either wanzu, souzu, or pinzu, you have three each of the 1 and 9, 1 each of all the other tiles in the suit, plus an additional one copy of any tile in the suit. You must be menzen, and it is worth yakuman.
If you meet these requirements such that you agari with a 9-way wait, it is called "Junsei [Pure] Chuuren Poutou".
On the other hand, if you agari on a wait for one specific tile, it is called "Junsei [Legitimized] Chuuren Poutou"!
Due to both terms being pronounced the same, when someone says junsei chuuren poutou these days, it generally means the 9-way wait.Example of Junsei [Pure] Chuuren PoutouExample of Junsei [Legitimized] Chuuren PoutouWaitOnly in this case will it be Chuuren PoutouIn these cases, it's MenchinThe chances of getting tenhou are about 1 in 330,000.
Rather than being a genius, it's more important to have incredible luck.Chiihou: When a ko's tiles from the haipai are something like below, and thenyou draw this on the first turn.Note: If any other player performs fuuro, you cannot get chiihouNext is "tenhou"!
This is a yakuman that you get when you agari on the haipai as the oya!
Also, if a ko gets a tsumo agari in the first turn, it's called "chiihou", which is also yakuman.
They're both yaku that you won't be able to get unless you're at least as much of a genius as Koromo!
