Reference values below follow the Hong Kong Mahjong Association (HKMA) rules. Worked calculator examples use our browser game’s house rules; check the differences before comparing results.
How many faan is self-draw?
Self-draw contributes 1 faan in the HKMA reference and our ordinary house scoring. It means the winning tile was drawn by the winner. It describes how the hand finishes, not a different fourteen-tile shape.
Our game treats a normal draw, a legal winning Kong replacement and the dealer’s initial extra tile as self-draw sources. The full hand and minimum must still be valid; a house limit replaces ordinary self-draw additions.
A complete 3-faan house example
The grouped hand has four Chows and a non-value pair, kept concealed. Under our house rules, All Chows 1 + Concealed Hand 1 + Self-draw 1 = 3, meeting the default minimum.
For 3 final faan, our house payment is 8 points from each opponent, so the winner gains 24. These are the game’s points. The separate half-laak comparison has different payments, and selecting self-draw there does not add the faan a second time.
Check shape, source, then the minimum
First complete the hand. Identify the actual winning tile and whether it came from your own draw. Then select a matching winning circumstance in the hand calculator and read the total after all eligible items and the cap.
The same tile from another player is a discard win
If another player supplies the winning tile in the saved example, Self-draw disappears. All Chows 1 + Concealed Hand 1 leaves 2, below the default 3-faan minimum. Drawing the tile yourself is not optional wording: it changes eligibility.
Kong Draw, Last Draw and limit hands
Our ordinary scoring adds Kong Draw 1 for an immediate winning Kong replacement, or Last Draw 1 for the final normal wall self-draw. Those two sources are different and cannot describe the same draw.
Other compatible ordinary patterns may combine up to our 8-faan cap. HKMA’s Concealed Hand bonus has separate no-flower and no-Kong conditions, so the house example’s concealment bonus must not be assumed for every table.

A hand to try
Win: self-draw · Seat: East · Round: East · Minimum: 3. Declared melds and special draw context are loaded with the hand.
With the saved win method, seat wind and round wind, this example is expected to score 3 final faan under sc_hk13_v1_2. The calculator also shows every contributing pattern and whether the hand reaches the selected minimum.
Try this in the calculatorA few things to know
Does self-draw always make a hand eligible to win?
No. It adds one ordinary faan in our game, but the completed hand must still reach the selected minimum. The Chicken Hand example rises from 0 to 1 on self-draw and remains below 3.
Is robbing an added Kong self-draw?
The winning tile comes from another player, so it is not the ordinary Self-draw condition. Some rules, including the cited HKMA rules, specify separate robbing-Kong bonuses and payment treatment. The hand calculator has no robbing-Kong selector.
