Hong Kong mahjong hands & scoring

Every winning hand starts with one base faan.

Every tile is a 2–8 — no terminals (1/9) and no honours.

A four-of-a-kind set. Each kong adds a faan.

A triplet of any dragon — Red (中), Green (發) or White (白).

A triplet of your seat wind or the round wind.

You drew the winning tile yourself (house option — many tables play +1).

You won on the tile someone added to a kong.

You won on the replacement tile drawn after declaring a kong.

You self-drew the winning tile on the very last tile of the wall ("scooping the moon from the seabed").

You won on the very last discard of the hand ("catching a fish from the riverbed").

Each flower or season the winner holds scores this. Flowers are extra tiles set aside, not part of the hand.

You won holding no flowers or seasons at all — a small bonus on a "clean" hand.

You never claimed a tile from anyone — the whole hand was built in hand.

All four of one colour — every season (春夏秋冬) or every flower (梅蘭菊竹).

You won on a second consecutive kong-replacement tile — a kong off a kong.

All four sets are runs and the pair is a plain (non-honour) tile.

The hand uses all five types of tiles — characters, dots, bamboo, a wind and a dragon.

A 1-9 straight split across the three suits — 1-2-3, 4-5-6 and 7-8-9, each run a different suit.

Two identical runs — the same three tiles, same suit, twice.

The same run in all three suits — e.g. 2-3-4 of characters, dots and bamboo.

One suit only, mixed with winds and/or dragons.

Four triplets (or kongs) plus a pair — no runs.

Every set and the pair touches a terminal (1/9) or an honour.

Seven pairs instead of four sets and a pair.

A full 1–9 run in one suit: 1-2-3, 4-5-6 and 7-8-9 all the same suit.

Triplets of two dragons plus a pair of the third.

Triplets of three winds plus a pair of the fourth.

Every set and the pair touches a terminal (1/9) — and no honours.

The whole hand is a single suit, no winds or dragons.

Holding all eight flowers and seasons — an instant win on its own.

Every set is a triplet of terminals — only 1s and 9s, no 2–8 and no honours.

A non-dealer wins on a discard in the very first go-around, before drawing any tile.

Four triplets all formed in hand (none claimed), won by self-draw.

A triplet of all three dragons — Red, Green and White.

A triplet of all four winds — East, South, West, North.

Every tile is a wind or a dragon — no number tiles.

Four kongs. Extremely rare.

Every tile is green: 2/3/4/6/8 bamboo and the Green dragon (發).

A full flush shaped 1-1-1-2-3-4-5-6-7-8-9-9-9 plus any extra of that suit.

One of every terminal (1 & 9 of each suit) plus every wind and dragon, one paired.

The dealer wins outright on the opening 14-tile deal — the rarest hand in mahjong.

A non-dealer wins on the dealer’s very first discard.
