Mahjong Scoring Explained: How Points Work in Hong Kong Mahjong

⏱ 10 min read

Scoring is what transforms Mahjong from a simple tile-matching exercise into a game of genuine strategic depth. Knowing which hand elements earn points — and how much — shapes every decision you make from the first discard to the final claim.

This guide covers Hong Kong Mahjong scoring in full. If you are new to Mahjong, read how to play Mahjong first.

The Faan System

Hong Kong Mahjong scoring is built on faan (番) — a point unit. Each scoring element in your winning hand contributes one or more faan. More faan means higher payment.

Two scoring structures are commonly used:

Doubling System (most common)

Each faan doubles the base payment. If the group plays at $1 per faan:

  • 1 faan = $1
  • 2 faan = $2
  • 3 faan = $4
  • 4 faan = $8
  • 5 faan = $16
  • 6 faan = $32
  • 7 faan = $64
  • 8+ faan = Limit

Flat Chart System

Each faan total maps to a fixed payment amount from a pre-agreed table. Less exponential, more predictable. Common in casual or family play.

Whatever system your group uses, confirm it before the first hand. Stakes and structure vary widely.

Limit Hands

Limit hands pay the maximum regardless of further calculation. In a $1-per-faan doubling game with an 8-faan limit, the limit might be set at $128 per player.

HandDescription
Heavenly Hand (天糊)Dealer wins on their initial 14-tile deal
Earthly Hand (地糊)Non-dealer wins on dealer’s first discard
Thirteen Orphans (十三幺)One of each terminal and honour, plus one duplicate
Three Great Scholars (三元牌)Pungs of all three dragons
Four Great Blessings (四喜臨門)Pungs of all four winds
All HonoursOnly wind and dragon pungs + pair
All Kongs (十八羅漢)Four kongs + pair
Pure One Suit (with pungs only)All tiles in one suit, all pungs — often classified limit

Payment Structure

Discard Win

When you win on another player’s discard:

  • The discarder pays you the full hand value
  • The other two non-winning players pay nothing

Exception: In some rule sets, all three players pay when you win by discard with an all-chow concealed hand (a rule designed to penalise overly conservative play).

Self-Draw Win (Zimo)

When you draw your own winning tile from the wall:

  • All three other players each pay you the full hand value

This is why self-draw wins earn dramatically more than discard wins — three payments instead of one.

Dealer Rules

When the dealer wins:

  • Every player pays double the standard amount (or the dealer collects double per player — same result)

When a non-dealer wins by discard from the dealer:

  • The dealer pays double while the other non-winning player pays standard
  • Or in some rule sets: the discarder (whoever they are) pays double and the others pay nothing — confirm your house rules

When the dealer wins by self-draw:

  • All three players each pay double

Worked Scoring Example

Winning hand:

  • Pung of Red Dragon (exposed)
  • Pung of 3-Bamboo (concealed)
  • Chow of 4-5-6 Bamboo (concealed)
  • Chow of 7-8-9 Bamboo (concealed)
  • Pair of 2-Bamboo

Won by self-draw. The hand is mixed one suit (all Bamboo, no honours except the Red Dragon pung… wait, Red Dragon is an honour, so this is a mixed suit hand).

Scoring breakdown:

  • Mixed one suit (Bamboo + one dragon honour): 3 faan
  • Dragon pung (Red Dragon): 1 faan
  • Self-draw: 1 faan

Total: 5 faan

In a doubling system at a $1 base:
5 faan = $1 × 2⁴ = $16 per player × 3 players = $48 total

If this player is the dealer, each player pays double: $32 × 3 = $96 total.


Minimum Hand Requirement

Many Hong Kong rule sets require a minimum of 3 faan to win. A hand that meets the structural requirement but scores fewer than 3 faan is a chicken hand (雞糊) and cannot win in those rule sets. The player who declared it typically pays each other player a small penalty.

A chicken hand can still happen by accident — building a valid four-sets-one-pair hand entirely of simples in mixed suits, won by discard, earns only 0 faan by default (all-chow discard win earns 0 unless you add the “all-chow discard” bonus, which is 1 faan). Know your house rules.


Quick Strategy Takeaways

Chase high-value elements early. If you can steer your hand toward mixed suit (3 faan) or pure suit (7 faan) from the start, the faan payoff justifies the extra difficulty.

Self-draw wins are worth 3× discard wins. A hand that pays $8 by discard pays $24 by self-draw (all three players pay). Keeping your hand concealed to maximise self-draw chances is often the right strategic choice.

Dragon and wind pungs are easy value. A dragon pung earns 1 faan for minimal sacrifice — hold your dragons longer than you hold simples.

Limit hands change the game. If you are dealt tiles pointing toward Thirteen Orphans or Three Great Scholars, the limit payoff may justify a high-risk pursuit.

Learn these concepts, then practice them in a live game at Mahjo — the scoring is calculated automatically so you can focus on learning which hand elements actually earn you points.

Frequently Asked Questions

How does scoring work in Mahjong?

In Hong Kong Mahjong, scoring is based on faan (番) — points earned by the elements in a winning hand. Each element (dragon pung, pure suit, self-draw win, etc.) contributes a number of faan. The total faan determines the payment. If you win by discard, only the discarder pays you. If you win by self-draw, all three other players pay you. Higher faan means larger payment.

What is faan in Mahjong?

Faan (番) is the scoring unit in Hong Kong Mahjong. Each scoring element in a winning hand contributes a certain number of faan. Many rule sets use a doubling structure: the base payment doubles for each faan. For example, if a 1-faan hand pays $1, a 2-faan hand pays $2, a 3-faan hand pays $4, and so on. Other rule sets use a flat chart where each faan value maps to a fixed payment.

What is a limit hand in Mahjong?

A limit hand is a winning hand that pays the maximum possible amount, regardless of how that maximum was calculated. Limit hands include Thirteen Orphans, Heavenly Hand, All Honours, Three Great Scholars (all three dragon pungs), and others. When a limit hand wins, every loser pays the limit value — the dealer does not pay double and there are no further multipliers.

What is the minimum to win in Hong Kong Mahjong?

Many Hong Kong Mahjong rule sets require a minimum of 3 faan to win. A hand that meets the structural requirement (four sets + one pair) but scores fewer than 3 faan is called a 'chicken hand' and is invalid in those rule sets. Other rule sets have no minimum. Always confirm the house rules before playing.

Does the dealer pay more in Mahjong?

Yes. When a non-dealer wins by discard, the dealer pays double the standard amount while the other two non-winning players pay the standard amount (in some rule sets) or the discarder alone pays (in others). When the dealer wins by self-draw, all three players pay double. When the dealer wins by discard, the discarder pays double the normal amount. Dealer status increases both the risk of paying and the reward of winning.

What does 'double' mean in Mahjong scoring?

In the doubling system (used in many Hong Kong Mahjong rule sets), each faan doubles the base payment. If the base is $1 for 1 faan, then 2 faan = $2, 3 faan = $4, 4 faan = $8, and so on. This exponential structure means high-value hands pay dramatically more than low-value hands. A limit hand (typically defined as 8+ faan or a named limit hand) pays the maximum regardless of further multipliers.
