'''Chiniisou''' {{kana|清一色}} is a standard [[List of yaku#Six han|yaku]].  This yaku is composed of tiles in one suit only. Chinitsu is worth 6 han, but it decreases to 5 han when opened. This yaku is usually referred to as '''chinitsu''' or, occasionally, '''chinichi'''.

===Complex wait patterns===
===Complex wait patterns===
Chinitsu is notorious for developing complex [[Machi#Complex_patterns|wait patterns]]. This is due to the homogenous nature of the yaku.  The number of potential waiting tiles may range from one tile of the suit to all nine tiles. Strings of consecutive numbers enable this complexity.  Without the help of computers, this complexity increases the difficulty in determining the winning tiles upon tenpai.
Chinitsu is notorious for developing complex [[Machi#Complex_patterns|wait patterns]]. Since all 13 tiles are of one suit, it is easy for groups to mix together, forming multi-sided waits. If playing without computers, it can be difficult to tell what your waits are.

Chinitsu requires a single suit, so that deems this yaku incompatible with other yaku that demand other tile types. That includes [[yakuhai]], [[shousangen]], as well as [[sanshoku]] and [[sanshoku doukou]]. Since chinitsu implies [[honitsu]], the latter is not counted together. If combined with [[chanta]], the hand is actually [[junchan]], so that yaku is counted instead. Finally, chinitsu and [[honroutou]] would require a hand containing at most eight tiles (the 1s and 9s of one suit), which is impossible.
Chinitsu requires a single suit with no honors. [[Yakuhai]], [[shousangen]], [[sanshoku]], and [[sanshoku doukou]] all require honors or multiple suits, and are thus incompatible. Chinitsu implies [[honitsu]], so they are not counted together. If combined with [[chanta]], the hand is actually [[junchan]], so that yaku is counted instead. Finally, chinitsu and [[honroutou]] would require a hand containing at most eight tiles (the 1s and 9s of one suit), which is impossible.
 
===Yakuman===
Due to the relatively high value of this yaku, chinitsu may be involved in the formation of [[kazoe yakuman]].  Especially when closed, the 6-han is enough to be almost half necessary to acquire 13-han.  Naturally, other yaku and/or dora will have to compose the rest.  Though, one particular pattern may form as the yakuman, [[chuuren poutou]].

As a standalone yaku, chinitsu is at least a [[mangan]], even when open. To regain the lost han as an open hand, it simply takes a [[dora]], or another yaku, to bring the hand up to its closed value of a haneman.


As a standalone yaku, chinitsu is at least a [[mangan]], even when open. To regain the lost han as an open hand, it simply takes just one dora, or a combination with another yaku, just to bring the hand up to its closed value of a haneman.
===Yakuman===
Due to the relatively high value of this yaku, chinitsu may be involved in the formation of [[kazoe yakuman]], especially when closed. The 6-han from closed chinitsu is almost half the requirement for 13-han; naturally, other yaku and/or dora will need to provide the next. Though, one particular pattern may form as a true yakuman, [[chuuren poutou]].
