How to play Mahjong
Goal. Over four hands, finish more winning hands — and more valuable ones — than the other three players. A winning hand is four sets and a pair.
The ruleset
- This table plays Hong Kong old style Mahjong with simple fan scoring, for exactly four players. Play solo against three computers, or open a private room for four friends.
- 136 tiles: three suits (characters, bamboo, dots) numbered 1 to 9, four winds (East, South, West, North) and three dragons (red, green, white), four copies of each. No flower or season tiles.
- A match is four hands. Each player deals once; the dealer is East for that hand and the others are South, West and North in playing order. The prevailing wind is East for the whole match.
Setup
- Every player receives 13 tiles. The dealer draws a 14th tile and starts by discarding.
- Fourteen tiles at the end of the wall are kept back as the dead wall. When only the dead wall is left, the hand ends as a draw.
On your turn
- Draw a tile, then discard one. Your discard goes face up in front of you.
- If the drawn tile completes your hand, declare Mahjong instead: a self-drawn win.
- With four identical tiles you may declare a concealed kong, or add a drawn tile to a pung you already showed. Either way you draw a replacement tile from the back of the wall, then discard.
Claiming a discard
- Pung: two matching tiles in your hand plus the discard. Anyone may pung.
- Kong: three matching tiles plus the discard; you then draw a replacement tile.
- Chow: a run of three in one suit (such as 3-4-5 bamboo). Only the next player may chow.
- Win: claim the discard if it completes your hand. A win beats a pung or kong, which beats a chow. If two players could win on the same tile, the one next in turn order takes it.
- Claimed sets are shown face up and play continues from the claimer, who discards next. A concealed kong stays hidden from the others until the hand ends.
Fan and points
- There is no minimum: a hand with no fan (a chicken hand) still wins.
- 1 fan each: self-drawn; concealed hand (no claimed sets); all chows; pung or kong of any dragon; of your seat wind; of East (the prevailing wind); winning on the last tile; winning on a kong replacement tile.
- 3 fan: all pungs; mixed one suit (one suit plus honours); small three dragons (two dragon pungs and a dragon pair) adds 3.
- 7 fan: pure one suit. Limit hands (8 fan): big three dragons, all honours, thirteen orphans (one of each terminal and honour, plus a pair of any of them).
- Fan are capped at 8. A hand is worth 2 to the power of its fan: 1 point at 0 fan, 2 at 1 fan, up to 256 at the limit.
- Self-drawn: each other player pays twice the value. On a discard: the discarder pays twice the value and the other two pay the value once.
End of the match
- After the fourth hand, the highest total wins. Equal top totals draw.
- Not played here: flowers, robbing a kong, seven pairs, dealer repeats and a minimum fan.
Controls
- Tap a tile in your hand to select it, then tap Discard (or tap the selected tile again). Keyboard: Tab to a tile and press Enter twice.
- When you can claim a discard, the claim buttons appear above your hand: Win, Kong, Pung, Chow or Pass. When no claim is possible, play moves on without asking.
- Your newly drawn tile sits at the right end of your hand, slightly apart.
Tips
- Discard lonely honours and terminals early; keep pairs and tiles next to each other in a suit.
- Claiming opens your hand and costs the concealed-hand fan, so claim when it brings you clearly closer.
- Watch the discards: a tile with three copies already showing cannot become a pung for anyone.
