Chinitsu (清一色) is a standard yaku. This yaku is composed of tiles in one suit only. Chinitsu is worth 6 han, but it decreases to 5 han when opened.

Formation
As defined, this yaku is formed by collecting tiles of one suit. Therefore, tiles not of a particular suit are regularly discarded. As a consequence, a player aiming for a chinitsu may be easily detected via discards alone.
Compatability
^ Ippatsu requires riichi to be of any use.

Chii toitsu
This yaku does not combine with chii toitsu. By definition, chii toitsu is formed by the collection of seven pairs. Although, ryanpeikou may be interpreted as a collection of seven pairs also. However, ryanpeikou is actually composed of sequences, rather than as independent pairs. The pattern simply appears as a collection of pairs.
Complex wait patterns
Chinitsu is notorious for developing complex wait patterns. This is due to the homogenous nature of the yaku. Often, the tiles may form long strings of consecutive numbers. Upon doing so, the wait patterns increase in complexity. Without the help of computers, determining the winning tiles upon tenpai may become somewhat of a task.
Yakuman
Due to the relatively high value of this yaku, chinitsu may be involved in the formation of kazoe yakuman.
