Tsuuiisou: Difference between revisions

A specific variant to tsuuiisou is possible and can be considered as a separate yakuman, '''daichiisei''' {{kana|大七星}}, which means "Big Seven Stars".  It is a variant of [[chiitoitsu]] (seven pairs). There are exactly seven types of honor tiles, which makes this difficult pattern possible but more difficult than the regular tsuuiisou.  As a consequence, this variation remains as a closed only hand.  This is [[optional yaku|optionally]] worth [[Multiple yakuman|double yakuman]].
