144 tiles: suited dots, bamboo, and characters, plus winds, dragons, flowers, and seasons.
East is dealer. Everyone gets 13 tiles, the dealer starts with 14 and discards first.
Flowers and seasons are set aside for bonus; draw replacement tiles before discarding.
Minimum 1 fan required under Hong Kong scoring.
Win with 14 tiles: four melds plus a pair, completed by self-draw or a discard.
Chow (sequence), pung (triplet), or kong (quad). Chows are suited tiles only.
You must reach the table minimum faan (often 3) to win.
Only the winner scores; all others pay based on the hand's faan value.
Draw, declare, discard with standard priority.
Draw from the wall, declare if needed, then discard to keep 13 tiles in hand.
Priority is win, then kong, then pung, then chow (from the left player only).
After declaring a kong, draw a replacement tile from the end of the wall before discarding.
Play pauses for flowers or seasons, meld claims, winning calls, or robbing a kong.
