門前清 · Mun Chin Ching
Concealed Hand (門前清 · Mun Chin Ching) is a Hong Kong mahjong scoring bonus: You built your whole hand yourself, never taking a tile from another player’s discard to complete a set. Mahjiku's default sheet prices it at 2 faan, and every win also carries the 1 faan base, so a hand whose only named line is Concealed Hand totals 3 faan. Under Mahjiku's default additive payout that 3 faan is the payment itself: the winner collects 9 points on a self-draw (自摸), when all three opponents pay 3 each, or 3 from the single player who discarded the winning tile (點炮). Faan values are a table's own call; this is Mahjiku's shipped default, editable in House Rules.
bonus block of Mahjiku's default rule set. House rules vary from table to table — this is one common setting, not the only "correct" one. Your table can price it differently; the engine reads whatever your rule set says.No sets were claimed off the table — everything came from your own draws.
A plain four-runs-and-a-pair hand, built entirely from your own draws. Claim even one set off the table and the Concealed Hand line disappears — the rest of the hand scores the same.
Passed to Mahjiku's scoring engine (self-drawn, fully concealed, seat wind South, round wind West), that hand comes back as:
| Line the engine emitted | Faan |
|---|---|
| Ping Hu平和 | +2 |
| Base底 | +1 |
| Concealed Hand門前清 | +2 |
| Total | 5 |
Faan is not the score by itself — it is the number the table turns into points, and Hong Kong tables do that two different ways. Both are shipped in Mahjiku; the additive model is the default.
| Payout model | One payer owes | Self-draw 自摸 | Discard 點炮 |
|---|---|---|---|
| Additivefaan is the payout | 5 | +15 | +5 |
| 半辣上half spicy | 24 | +72 | +24 |
| 辣辣上full spicy | 32 | +96 | +32 |
Self-draw: all three opponents pay. Discard: only the player who threw the tile pays. Both columns are the winner's gain, straight out of the app's settlement function.
