Start with these ideas
- Our house rules award 1 for a discard win immediately after the final normal draw.
- The cited HKMA list includes last-tile self-draw but does not separately list this Last Discard award.
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.
Which discard qualifies in our game?
The winning tile must be the discard immediately after the final normal wall draw. It is a win from another player, not self-draw, and our Last Discard item excludes robbing an added Kong.
The latest tile in the discard area is not automatically this final discard. You need the actual wall and turn context.
One house faan; confirm other tables separately
Street Corner awards Last Discard 1. The cited HKMA faan list describes last-tile self-draw but does not separately list this discard-win item. Do not use our 1-faan value as evidence of an HKMA bonus.
Our saved hand scores All Chows 1 + Concealed Hand 1 + Last Discard 1 = 3. No self-draw faan is included. House limit hands replace ordinary event bonuses.
Do not add both sea-bottom events
You either draw the winning tile yourself or take another player’s discard. Switching between those events changes the winning method as well as the event selector. The calculator does not reconstruct the final turn from the tiles.
See why the ordinary discard win is rejected
Load the example and keep On a discard selected. Change the circumstance to Normal win: the house total becomes 2 and fails the default 3-faan minimum. This shows why the event must be genuine, not selected merely to reach the threshold.

A hand to try
Win: discard · 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.

A few things to know
Does the calculator verify that the wall was empty?
No. It checks the selected hand and compatible winning context, but it has no record of the table’s wall. You must supply the correct event; the browser game tracks its own actual draws separately.
