A hand missing an entire suit, not scored here.
Your hand uses only two of the three suits, leaving one suit entirely absent. In Mahjong Winds it scores nothing by default, which is why the badge on this page reads zero. It is a knob our rules can switch on, worth one faan when a table enables it.
There is nothing to chase, because a hand that never happens to draw a suit has voided it without trying. That is precisely the problem with scoring it, and the reason it is off here.
Assuming it is a Hong Kong pattern. It is not. It is absent from both tournament rulebooks and from the orthodox list, which files it under house rules and treats it as zero under standard play. It belongs to the Guangdong additions, not to the Hong Kong game.
Where a table enables it, it adds one faan to anything. We measured why it matters: it fired on 40 percent of wins and was our largest single faan source. An ordinary two-suit hand was clearing the three faan minimum largely on it, which is the distortion that argued for switching it off.
Why does this page show zero faan?
Because our rules do not score it. It is kept as a switch a Guangdong or Singaporean table would turn back on.
Is it the same as Mixed One Suit?
No. Mixed One Suit uses one suit plus honours and scores three. This is merely the absence of one suit out of three.
What happens if a table enables it?
It becomes one faan. We shipped it at two once, on a single hedged source, and corrected that to one.
