Hong Kong Mahjong Rules

What is Hong Kong mahjong?

Hong Kong mahjong is the version most English-speaking players meet first, usually at a family table or in a Chinese restaurant back room. It uses 136 tiles, 13 in hand, and allows every claim — including chow.

Its defining feature is not a special rule but a low threshold. Three fan is enough at many tables, which means a beginner can win a hand in the first hour of play. That is deliberate: the game is built for social play, not competition.

Setup

Four players, walls of 17 stacks, dealer takes 14 and everyone else 13. Play passes counter-clockwise. There are no flowers in the standard 136-tile game; some house sets include them, in which case each flower scores one fan and is replaced by a tile from the wall.

Seats are named east, south, west and north. East deals first, and the round wind advances after each full rotation.

The minimum hand

Before the first hand, ask one question: three fan or eight fan? Both are common, and the difference is large. At three fan, almost any hand with one small pattern qualifies. At eight fan, the table is effectively playing Chinese Official rules with a smaller tile set.

Most scoring patterns are the familiar ones: all triplets, half flush, full flush, three colour straight, pure straight, dragon triplets, and the self-draw bonus. A hand with no pattern at all is usually not legal even at three fan — a completely plain hand scores too little to count.

How scoring works

Fan are added up and converted to points by a table rate. Common rates pay a fixed amount per fan, with the dealer paying and receiving double. There is no fu calculation and no complex cap; the arithmetic is deliberately simple so it can be done out loud at the table.

Situation	Who pays	Who receives
Win on a discard	The discarder, in full	The winner
Self-drawn win	All three opponents	The winner
Dealer win	Each opponent pays double	The dealer
Dealer loses	The dealer pays double	The winner

This dealer doubling is what makes the seat matter: winning as dealer is worth roughly twice as much as winning as a non-dealer, and losing as dealer costs twice as much.

Dealer rotation and game length

A dealer who wins keeps the seat. A dealer who does not win passes the deal to the next player. After four seats, one round is complete; most social games play four rounds, which takes roughly an hour and a half.

A single hand runs 15 to 20 minutes at a relaxed table, longer if players are learning.

Differences from the other Chinese styles

Rule	Hong Kong	MCR	Sichuan
Tiles	136	144	108
Honours	Used	Used	Removed
Minimum	3 fan (often)	8 fan	Dropped suit + 1 fan
Flowers	Usually none	Eight, scoring	None
Round end	First winner	First winner	Three winners

If you learn Hong Kong first, moving to MCR mainly means raising the minimum and learning the fan table. Moving to Taiwanese means relearning the hand shape entirely.

Common beginner mistakes

• Assuming no-chow. Hong Kong allows chow. American mahjong is the style that bans chow, and British rules allow only one per hand.
• Playing to eight fan at a three-fan table. You will miss wins you could have taken with a cheap pattern early.
• Forgetting the dealer premium. A dealer hand is worth double in both directions; defending as dealer is more valuable than defending as a non-dealer.
• Not confirming the table rate. Points per fan vary widely, and a "friendly" game can still be expensive if the rate is high.

Quick answers

Can you chow in Hong Kong mahjong?

Yes, from the player on your left. This is the main difference from American mahjong, which bans chow entirely.

How many fan do you need to win?

Usually three, but some tables require eight. Ask before the first hand; the difference changes how you play every turn.

Are flowers used?

Not in the standard 136-tile game. Some house sets add them, in which case each flower scores one fan.

Is Hong Kong mahjong the same as Cantonese mahjong?

Largely, yes. The terms are used interchangeably in English, though local tables vary on the minimum and the point rate.
