Hong Kong, HKMA 2023 scoring

This guide explains supported hand scoring and settlement. Companion validates a scorable hand, not complete gameplay.

General information

Hong Kong Mahjong is a four-player game. Players draw and discard tiles until a player wins or the wall ends.

This profile uses HKMA 2023 patterns. Set the table minimum from 0 through 5 faan, and scoring stops at 10 faan.

Companion derives faan from the confirmed hand, declared groups, winds, win source, and selected special event. Set the table minimum faan before you record a result.

How to play

  1. Deal 14 tiles to East and 13 tiles to each other player.
  2. East discards one tile to start the hand.
  3. On each turn, draw one tile and discard one tile.
  4. Declare chi, pon, or kan when the table rules permit it.
  5. End the hand when a player wins or the wall has no draw.

How to win

  • Make a supported standard hand or Thirteen Orphans.
  • Meet the selected minimum faan requirement from 0 through 5.
  • Win by self-draw or by claiming another player's discard.
  • Select supported special wins explicitly. Companion does not apply liability or simultaneous-winner rules.

Scoring patterns

The HKMA source assigns faan to each pattern. Companion detects supported patterns, adds their faan, and applies the 10-faan cap.

Companion sets flower tiles aside. This HKMA profile assigns them no separate faan value.

How to calculate score

What you enter

This profile settles a four-player table.

Enter the confirmed tiles, declared groups, winning tile, seats, round wind, win source, and any supported special event. Set the table minimum faan.

Companion detects each supported pattern, adds its faan, checks the selected minimum faan, and applies the 10-faan cap.

Score changes

On a discard win, only the discarder pays the table value. On a self-draw, each of the three opponents pays half of that table value.

The table pays nothing below three faan. At minimum 0, Companion records a zero-faan win without score changes.

Hong Kong table values for 3 to 10 faan
FaanDiscarder paysEach self-draw payer pays
33216
46432
59648
612864
719296
8256128
9384192
10512256

Worked example

Example: 5-faan discard win = 96 points

At 5 faan, the table value is 96. Only the discarder pays 96. On a self-draw, each opponent pays 48.

Wind and dealer

Dealer status does not change this basic score table.

A seat-wind or round-wind triplet or quad adds 1 faan for each matching role. Companion detects both roles.

Tiles introduction

Number tiles belong to three suits: characters, circles, and bamboo. Each suit has ranks 1 through 9.

Honor tiles are winds and dragons. A standard tile set contains four copies of each numbered and honor tile.

Hong Kong tables can use eight flower tiles. Companion sets them aside, and this profile assigns them no separate faan.

  • 1m
  • 2m
  • 3m
  • Red
  • Spring

Tiles in the Hong Kong example

Companion sets flowers aside. HKMA hand scoring assigns them no separate faan in this profile.

Combinations

A group is a sequence, triplet, or quad. A standard winning hand uses four groups and one pair.

Identify each fixed chi, pon, or kan as a declared group. A declared kan can be exposed or concealed.

  • Sequence

    Three consecutive numbered tiles in one suit. Example: 2, 3, and 4 of characters.

  • Triplet

    Three identical tiles. Example: three red dragons.

  • Quad

    Four identical tiles. Example: four East tiles.

  • Pair

    Two identical tiles. A standard hand uses one pair.

Hong Kong and Singapore support Thirteen Orphans. These profiles exclude Seven Pairs.

Scoring vocabulary

Declared group
A declared group is a fixed chi, pon, or kan. A declared kan can be exposed or concealed.
Ron
Ron is a win on another player's discard. The discarder pays the score charge in the applicable profile.
Tsumo
Tsumo is a win from your own draw. The other players provide the score charges.
Faan

Faan is the total value of scoring patterns in a Hong Kong hand. Companion derives and caps this total.

Example: 5 faan selects a 96-point table value in this profile.

Table value

The table value is the point amount selected by the faan table. A discard win charges it to the discarder.

Example: 5 faan gives a 96-point table value here.

Han

Han is not an input in this Hong Kong profile. Use faan as the scoring unit.

Example: a detected 5-faan hand uses the Hong Kong table, not Riichi han.

Fu

Fu is not an input in this Hong Kong profile. It does not change this basic faan table.

Example: fu does not change a Hong Kong result.

Limitations

Companion excludes HKMA liability and simultaneous winners. It supports robbing a kong but cannot prove the complete call history.

Companion validates a scorable hand. It does not prove wall history, missed calls, claim order, or complete gameplay.
