Singapore, 0 to 5 tai scoring
This guide explains supported hand scoring and settlement. Companion validates a scorable hand, not complete gameplay.
Singapore rules vary by table. This profile follows the Singaporean Mahjong Reference and excludes incompatible local variants.
General information
Singapore Mahjong is a four-player game. Local tables can use different tile sets, calls, bonuses, and score rules.
This profile derives 0 to 5 tai from the Singaporean Mahjong Reference. The minimum tai requirement is adjustable.
Set the one-tai share and minimum tai requirement before you record a result.
How to play
- Deal 14 tiles to East and 13 tiles to each other player.
- East discards one tile to start the hand.
- On each turn, draw one tile and discard one tile.
- Follow your table's rules for bonus tiles, animals, declared groups, and special wins.
- End the hand when a player wins or the wall has no draw.
How to win
- Make a supported fourteen-tile-equivalent winning form.
- Meet the selected minimum tai requirement from 0 through 5.
- Set flowers and seasons aside. This version ignores animal tiles and animal tai.
- Win by self-draw or discard claim according to your table's rules.

Tai values and score shares
Let V be the one-tai share value entered in Companion. Each additional tai doubles the share.
| Final tai | Each share | Calculation |
|---|---|---|
| 1 | V | V |
| 2 | 2V | V × 2 |
| 3 | 4V | V × 4 |
| 4 | 8V | V × 8 |
| 5 | 16V | V × 16 |
How to calculate score
What you enter
This profile settles a four-player table.
Enter the confirmed hand and win context. Set the minimum tai requirement and the one-tai share value.
Companion detects supported tile, flower, wind, and event patterns. This version ignores animal tiles and animal tai.
One share = one-tai value * 2^(tai - 1).
Score changes
On a discard win, the discarder pays two shares and each other opponent pays one share. On a self-draw, every opponent pays two shares.
Dealer status does not add a settlement multiplier in this profile.
Worked example
Example: 3 tai with a 1-point one-tai share
One share = 1 * 2^(3 - 1) = 4 points.
For a discard win, the discarder pays 8 and each other opponent pays 4, so the winner receives 16 points.
Wind and dealer
Dealer status does not add a settlement multiplier in this profile.
A seat-wind or round-wind triplet or quad adds 1 tai 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.
Companion supports flowers and seasons as set-aside bonus tiles. This first version ignores animal tiles and animal tai.

Tiles in the Singapore example
Companion sets flowers and seasons aside, then detects seat matches and complete bonus sets.
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.
- Tai
Tai is the value of detected Singapore patterns. The effective total ranges from 0 through 5.
Example: detected patterns worth 3 tai use the 3-tai share multiplier.
- One-tai share
A one-tai share is the point value at 1 tai. Each extra tai doubles the share.
Example: a 1-point share becomes 4 points at 3 tai.
- Han
Some tables use fan or han for doubles. This profile uses tai consistently.
Example: Companion reports 3 tai, even when another table calls that value 3 han.
- Fu
Fu is not used by this Singapore profile.
Example: fu does not change a Singapore result.
Limitations
Companion ignores animal tiles and animal tai. It also excludes seven-pair hands and bonus-tile instant wins.
Companion does not apply pay-all liability or validate complete gameplay. Set the table's one-tai share and minimum tai requirement explicitly.
