How Singapore / Malaysia mahjong scoring works (4 players)
Four-player mahjong in Singapore and Malaysia is counted in tai (many Malaysian tables say fan). Common house rules are a 1-tai minimum and a 5-tai cap. Tai convert to a base value:
| Tai | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| Base | 1 | 2 | 4 | 8 | 16 |
- Win off a discard: the discarder loses 2× base and the other two lose 1× each, so the winner gets 4×. 3 tai: discarder −8, the others −4 each, winner +16.
- Discarder covers all (option): the discarder alone loses 4×.
- Self-draw: all three lose 2× base, so the winner gets 6×.
- Liability: the liable player alone covers the whole win.
- Instant bonuses, recorded any time during the hand, from each other player: cat + rat or rooster + centipede 2 per pair (4 if dealt at the start), your own seat flower and season 2 (4 at the start), all four animals 4 more, four flowers or four seasons 4, exposed kong 1, concealed kong 2. On a draw the hand scores nothing, but instant bonuses stand. A concealed kong: +6 for the player, −2 for each other player.
3-player mode (Malaysia)
5 fan to win, 10 fan is the limit. Hand points = 100 + 20 × (fan − 5), limit 200. On a self-draw both others lose 2×; off a discard the discarder loses 2× and the other player 1×. A 7-fan hand is 140: self-drawn, −280 each and +560 for the winner.
Fei (joker) is entered at the end of the hand: 50 points per Fei, compared between every two players. A 0, B 1, C 3: A −200, B −50, C +250.
Keep score in three steps
- Choose Malaysia / Singapore mahjong, pick 4-player or 3-player, enter players by seat and choose the first dealer and base points.
- Record each win (who, self-draw or discard, how many tai). Tap Instant bonuses whenever an animal, flower set or kong comes up.
- Check each player's +/− and save. Dealer and wind move on automatically; make a share image at the end.
House rules you can change before you start
Minimum and cap, discard mode, dealer doubles, every instant bonus value (or switch them all off), double-limit hands, and whether to show tai or fan. Rules lock at the start; any hand can be edited, deleted or undone.
