How Chinitsu (清一色) works
Chinitsu (full flush) is a hand built entirely from a single suit — all characters, all circles, or all bamboo — with no honor tiles.
Every tile, including the pair, must be of one number suit; no honors and no mixing of suits is allowed. It works open or closed but loses one han when opened. As one of the highest-value standard yaku, it commonly stacks with pinfu, tanyao, ittsuu, and sanshoku-style shapes within the suit.
Good to know
- •Contains zero honor tiles — adding any honor makes it honitsu instead.
- •Drops one han when the hand is open compared to concealed.
- •Often hides extra yaku like ittsuu or iipeikou within the single suit.
Chinitsu (清一色) — FAQ
What is the difference between chinitsu and honitsu?
Chinitsu is one number suit with no honors; honitsu is one number suit plus honor tiles. Chinitsu is the purer, higher-value version.
Can chinitsu include a kan?
Yes, as long as the kan tiles are of the same suit. The single-suit requirement applies to every tile in the hand.
