Tile pattern
Tsuuiisou is also possible as a variant of chii toitsu (seven pairs). This variant uses two of the each honour tiles and is sometimes called a "Dai Chii Sei" or Big Seven Stars. Optionally worth Double Yakuman.
Formulation
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.
