A specific variant to tsuuiisou is possible and be considered as a separate yakuman, '''daichiisei'''. It is a variant of [[chiitoitsu]] (seven pairs). This variant uses two of the each honour tiles and is sometimes called a "Dai Chii Sei" or Big Seven Stars. There are exactly seven types of honor tiles, which makes this difficult pattern possible. As a consequence, this variation remains as a closed only hand. This is optionally worth [[optional yaku|double yakuman]]. | |||

Tsuuiisou (字一色) is a yakuman in which the hand consists entirely of honour tiles.
Tile pattern
Agari: or
Formation
For this yakuman, all kazehai (wind tiles) and sangenpai (dragon tiles) can be used. Given the nature of jihai (honor tiles), they different types cannot be mixed into a meld. Therefore, they must be collected in the form of koutsu (triplets). This yakuman is only reasonably achievable, when in possession of at least multiple toitsu (pairs) of the honor tiles.
