''' | '''Junchantaiyaochuu''' {{kana|純全帯么九}} is a terminal based [[yaku]]. For this yaku, every [[mentsu|tile group]] and the [[jantou|pair]] must contain at least one [[terminal]] (1 or 9). Additionally, at least one tile group must contain a non-terminal tile, or else [[chinroutou]] will be scored instead. Junchan is similar to [[chantaiyao]], but chanta allows honors in addition to terminals. This yaku is more commonly referred to as '''junchan''' {{kana|純全}} or occasionally '''junchantaiyao''' {{kana|純全帯么}}. | ||

Like chanta, a hand going for junchan will often discard middle tiles before discarding 1-3 and 7-9 tiles. Because junchan is close to chanta, honor tiles may be discarded later than normal (since keeping the honors could let you go for chanta + [[yakuhai]]). | |||

Junchan | Junchan requires terminals and no honors, so it is incompatible with [[tanyao]], [[yakuhai]], and [[shousangen]]. [[Ittsu]] is incompatible as it requires a 456 sequence. A [[honitsu]] hand that has junchan would actually be [[chinitsu]]. A [[toitoi]] or [[honroutou]] hand with junchan would be instead [[chinroutou]]. [[Chiitoitsu]] requires seven unique pairs, but there are only six different types of terminals. Finally, because junchan implies [[chantaiyao]], both cannot be counted with a single hand. | ||
