Big Three Dragons

大三元 · Dai Saam Yuen

Big Three Dragons (大三元 · Dai Saam Yuen) is a Hong Kong mahjong hand: A triplet of all three dragons — red, green and white together. A dream hand. Mahjiku's default sheet prices it at 18 faan, and every win also carries the 1 faan base, so a hand whose only named line is Big Three Dragons totals 19 faan. Under Mahjiku's default additive payout that 19 faan is the payment itself: the winner collects 57 points on a self-draw (自摸), when all three opponents pay 19 each, or 19 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.

What the engine scores that hand at

These are not illustrative numbers: the tiles above were passed to Mahjiku's scoring engine (won on a discard, with sets claimed from the table, seat wind North, round wind North) and this is the breakdown it returned.

What 19 faan actually pays

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.

Additivefaan is the payout19+57+19
半辣上half spicy384+1152+384
辣辣上full spicy8192+24576+8192

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.

Worth knowing. Both doubling tables stop at 13 faan, so this 19-faan hand is paid at the 13-faan row — 384 points under 半辣上 and 8192 under 辣辣上. Everything above 13 faan pays the same. The additive model has no ceiling, so there the extra faan still count.
