All One Suit (清一色)
Every tile in the hand is in a single suit, with no honors at all. Also called Full Flush.
How All One Suit (清一色) works
A complete hand built entirely from a single suit — all dots, all bamboo, or all characters — with no honor tiles at all.
Every set and the pair must come from one of the three numbered suits, and no winds or dragons may appear. It is one of the highest-scoring suit patterns and outranks its mixed counterpart, Half Flush, which permits honors. Because the shape is unrestricted within the suit, it readily combines with sequence- or triplet-based faan.
- •Adding even one honor tile downgrades the hand to Half Flush rather than Full Flush.
- •It cannot coexist with Half Flush; a hand is one or the other, never both.
- •Limit-style hands such as Nine Gates are specific Full Flush shapes and supersede the plain pattern.
All One Suit (清一色) — FAQ
Are honor tiles ever allowed?
No. Any wind or dragon disqualifies a Full Flush; with honors present the hand scores only as the lower Half Flush.
Does the hand need to be concealed?
No. Full Flush may be melded with exposed sets, though keeping it concealed can earn separate concealed-hand credit.
