Tsuuiisou is also possible as 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]].
