'''Tsuuiisou''' {{kana|字一色}} is a [[List of yaku#Yakuman|yakuman]] in which the hand consists entirely of [[Jihai|honor tiles]].


==Tile pattern==
==Tile pattern==
{{#mjt:1112227776644z}} Agari: {{#mjt:6z}} or {{#mjt:4z}}
{{#mjt:1112226644z}} {{#mjt:7'77z}} Agari: {{#mjt:6z}} or {{#mjt:4z}}


== Development ==
For this yakuman, all [[kazehai]] (wind tiles) and [[sangenpai]] (dragon tiles) can be used. This gives seven tiles to choose from.


Tsuuiisou is also possible as a variant of [[chii toitsu]] (seven pairs). This variant uses two of the each honour tiles.
Honor tiles can only be formed as triplets or pairs. Therefore, this yakuman is only reasonable when in possession of multiple [[toitsu]] (pairs) of the honor tiles. Otherwise, you can go for yaku like [[yakuhai]] and [[honitsu]]. Regarding tile discards, any tile that is not an honor tile is deemed irrelevant for the yakuman, including [[dora]] tiles.  More often than not, players will call pon in order to claim and complete honor tile groups, until tenpai and eventually winning the hand (assuming to be the case).


== Daichiishin ==
{{#mjt:1122334455667z}}  Agari: {{#mjt:7z}}
{{#mjt:1122334455667z}}  Agari: {{#mjt:7z}}


In addition to triplets, tsuuiisou can be achieved in the form of [[chiitoitsu]]. This may be considered as a [[Optional yaku|separate yakuman]], '''daichiishin''' {{kana|大七星}}, meaning "Big Seven Stars".  There are exactly seven types of honor tile, and you cannot call pon to complete the hand, so this is much harder than regular tsuiisou. This is [[optional yaku|optionally]] worth [[Multiple yakuman|double yakuman]].
