Mixed Flush (混一色)

What is Mixed Flush?

Mixed Flush (混一色), also called Mixed One Suit, is a 3-faan Hong Kong Mahjong winning hand consisting of tiles from a single numbered suit (Bamboos, Characters, or Circles) plus any combination of honor tiles (winds and dragons). It’s one of the most accessible 3-faan hands and a frequent path to clearing the minimum-faan threshold.

How to score Mixed Flush

The hand must contain tiles from exactly one of the three numbered suits — Bamboos (索子), Characters (萬子), or Circles (筒子) — combined with any number of honor tiles. The four melds and pair must use only tiles from the chosen suit and the honor pool. Mixing two numbered suits disqualifies the hand.

Mixed Flush allows any meld type (chow, pung, kong) within the chosen suit. Honor tiles, by definition, can only form pungs, kongs, or pairs since they can’t sequence.

Example hand

Faan value: 3

Mixed Flush is worth 3 faan, paying 8 base units. It single-handedly clears the standard 3-faan minimum, making it one of the most popular target hands when a player draws a strong opening in one suit.

Common combinations

Mixed Flush stacks well with structural patterns since its constraint is on tile origin, not meld shape:

• Mixed Flush + All Triplets (對對胡) — 3 + 3 = 6 faan. All four melds are pungs or kongs in the chosen suit + honors.
• Mixed Flush + Concealed Hand (門前清) — 3 + 1 = 4 faan, when no melds were claimed.
• Mixed Flush + Self-Pick (自摸) — 3 + 1 = 4 faan on a self-drawn winning tile.
• Mixed Flush + Big Three Dragons (大三元) — 3 + 8 = 11 faan, when honors include three dragon pungs.

Mixed Flush is upgraded into Full Flush (清一色, 7 faan) if the hand drops all honors and uses only the chosen numbered suit. The two are mutually exclusive — you score one or the other, not both.

It is also the stepping stone to All Honors (字一色, 10 faan), which removes all suited tiles entirely.
