'''Ryuuiisou''' (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. | '''Ryuuiisou''' (緑一色) is one of the standard [[List_of_yaku#Yakuman|yakuman]] hands.

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. | |||
Even though all paint on the haku (white dragon, has no painting at all) is green, it doesn't count as a green tile. | |||
