Honiisou: Difference between revisions

'''Honitu''' {混一色) is a standard [[yaku]].  Normally translated as a "half flush", this yaku features a hand composed only of honour tiles and tiles of a single suit. If the hand contains no honours, then the [[chinitsu]] yaku is counted instead.

{{Yaku compatibility table|HON}}

Honitsu is aligned to a single suit.  Therefore, this yaku is compatible with other yaku, that follows that pattern; and multiple suited yaku do not apply, namely [[sanshoku]] and [[sanshoku doukou]].  Naturally, the "single suited" yaku of [[ittsu]] can merge with honitsu, only if the fourth [[mentsu|tile group]] is of the same suit or is a set of honours.  Other yaku are able to function with multiple suits; but they are also possible using single suits, namely [[toitoi]] and [[sanankou]].  The same applies for [[chiitoitsu]].  Commonly, this yaku works with [[yakuhai]], and likewise, [[shousangen]].

Of course, honitsu is not compatible with [[chinitsu]], because every chinitsu hand is honitsu. A honitsu combined with a [[tanyao]] would actually imply the chinitsu instead, since there would be no honours. It is also not compatible with junchan, as that would require the hand to contain only 1s and 9s of the same suit, which is only eight available tiles.
