Honiisou (or honitsu) 「混一色」 is a standard yaku. Normally translated as a "half flush", this yaku features a hand composed only of honor tiles and tiles of a single suit. If the hand contains no honor tiles, then the chinitsu yaku is counted instead.

Tile pattern

Agari: or

Formation

Naturally, it is easier to form honitsu when your hand starts with many tiles of the same suit. It is often unwise to break up a completed sequence of a different suit to force honitsu (though if you really need points, it's possible).

Detection

A player's discard pile may lack one particular suit. This may be an indicator of a honitsu hand being developed.

Compatibility

HON

Most yaku which allow one suit of tiles are compatible honitsu. This excludes sanshoku and sanshoku douku, which require use of all three suits. Honitsu is not compatible with chinitsu, because every chinitsu hand is honitsu. Honitsu combined with tanyao or junchan would actually imply chinitsu instead, since there would be no honours.

Honitsu is commonly paired with with yakuhai (calling pon for honor tile speeds up hand), ittsu (which already has 9 tiles of the same suit), and shousangen (which already has 8 honor tiles).

Value

This yaku is affected by kuisagari. The hand value decreases by 1 han when open. Honitsu can still be used for open hands, though. When combined with other yaku and/or dora, the -1 han is not a significant loss of value. For example, honitsu + yakuhai + dora 1 is worth ~7700, and the +1 han from closed only brings it up to 8000.

Bakahon

Bakahon 「バカホン」 is a slang term for a honitsu-only hand with open calls and no dora. This hand only scores 2000 points, which is not worth the amount off effort required for honitsu. (Since every 1 han doubles the score until 8000, even something like open honitsu + 1 dora is worthwhile.)

 {{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]].

 ==Value==
-This yaku is affected by [[kuisagari]].  The hand value decreases by 1 han when open.  Despite that property, honitsu hands can produce value as it is still 2 han when open.  Added value can easily be gained with the combination of another yaku or even some dora.  In this case, honitsu hands can be conveniently open without significantly losing value.
