Mixed One Suit (混一色)
A single suit combined with honor tiles.
How Mixed One Suit (混一色) works
The whole hand uses tiles from a single suit (dots, bamboo, or characters) together with honor tiles (winds and dragons).
Mixed One Suit is formed when every set and the pair are drawn from just one of the three number suits plus any honors, with no tiles from the other two suits. The honors can appear as pungs, kongs, or as the pair. It is the lower-tier cousin of Pure One Suit and the two are mutually exclusive, since a pure flush by definition contains no honors.
- •Including a single tile from a second number suit breaks the pattern entirely.
- •It cannot be scored together with Pure One Suit; a hand is one or the other.
- •Honor sets inside the hand may still earn their own tai (such as dragon or wind pungs) on top.
Mixed One Suit (混一色) — FAQ
How is Mixed One Suit different from Pure One Suit?
Mixed One Suit allows honor tiles alongside the single number suit, while Pure One Suit forbids all honors and uses only number tiles of one suit.
Can a Mixed One Suit hand have no honors at all?
If it has no honors, it is actually a pure flush and would score as Pure One Suit instead, not Mixed One Suit.
