'''Ryuuiisou''' {{kana|緑一色}} is one of the standard [[List_of_yaku#Yakuman|yakuman]] hands. This hand consists of any four melds and a pair that consists of only 2, 3, 4, 6, 8 of souzu and/or the green dragon tiles.  Literally, this hand is composed of "all green" painted tiles. This hand may be open or closed.

This hand may be open or closed.

This hand may regularly be subject to furiten, especially around the range of 1, 2, 3, 4, and 5 sou.  While it is necessary to discard 1 sou and 5 sou to build this yakuman, these discarded tiles may lead to a tenpai hand with furiten.  That may be particularly true for above example.

Some rules require hatsu (green dragon) in the hand, among them JPML A. The [[Tenhou.net rules]] and the [[EMA rules]] allow ryuuiisou with and without hatsu. This is the more common rule.
Some rules [[Yaku_variations#Ryuuiisou|require hatsu (green dragon)]] in the hand, among them [[JPML|JPML A]]. The more common rule includes hatsu within the hand.
 
Even though all paint on the haku (white dragon, has no painting at all) is green, it doesn't count as a green tile.
 
As with [[chinroutou]], there are 6 tiles available, so a seven pair variation (like the one in [[tsuuiisou]]) is impossible.
