How Honitsu (混一色) works
A half-flush — every tile belongs to a single suit, mixed with any honor tiles (winds and dragons).
Honitsu is formed when the entire hand uses only one of the three number suits plus any combination of honor tiles, with no tiles from the other two suits. It can be built open, though concealment raises its value by one han. It commonly stacks with yakuhai, toitoi, and other patterns, and upgrading by removing all honors turns it into the full chinitsu flush.
Good to know
- •Only one number suit is allowed; any tile from a second suit voids it.
- •Honor tiles are permitted and often pair with yakuhai for extra han.
- •Open hands qualify but score one han less than the closed version.
Honitsu (混一色) — FAQ
What separates honitsu from chinitsu?
Honitsu allows honor tiles alongside the single suit, while chinitsu permits no honors at all and is worth more.
Can honitsu be an open hand?
Yes. It can be called, but an open honitsu is reduced by one han relative to the concealed form.
