Taiwanese 16-Tile Mahjong rules and scoring

The basics
The 16-tile game
Taiwanese Mahjong is played with 16 tiles. A winning hand needs five sets and one pair, and several special hands are also possible. This allows for more tile combinations and decisions than other Mahjong types, making for an exciting game!

Four players sit at the table at East, South, West and North seats. East is the dealer.
Each hand also has a Wind that cycles across East, South, West, North.
A round consists of multiple hands. A game can consist of multiple rounds.
There are 144 tiles:
Three Suits
Circles, Characters, and Bamboo. Each has four copies of #1-9.
Four Winds
East, South, West, North. Four copies of each.
Three Dragons
Red, White, Green. Four copies of each.
Eight Flowers
Blue #1-4, Red #1-4.
Winds and Dragons are known as Honours.
Each player holds 16 tiles. Whoever’s turn it is briefly holds a 17th.
The objective is to form a winning hand consisting of five sets and one pair, or a special hand.
Points are earned or deducted from each player based on their hand score and special points awarded during the hand. These add up cumulatively across hands. To win a hand, a player must achieve a minimum hand score.

Before the game starts
Every game opens with a ceremony that decides where each player sits and where the wall is broken. All counting, draws and dealing are counter-clockwise around the table.
Finding the East seat
Whoever joins last rolls three dice and starts counting from themselves. Wherever the number lands is marked as the East seat. The other seats are marked counterclockwise from East: South, West, North.
Finding each player’s seat
The player in the East seat rolls and starts counting from themselves. The player the number lands on draws first from a stack of the four Wind tiles, and then the remaining players draw from that stack. Each person moves to the seat representing the Wind they drew. The person in East seat is the dealer.
Forming the wall
The 144 tiles are then built into a wall with four sides. Each side is 18 tiles long and two tiles high.
Breaking the wall
The dealer rolls and counts starting from themselves.
The player the number lands on breaks the wall in front of them by counting the number on the dice (starting from the right end of the wall in front of them), and breaking the wall at that point. The 16 tiles behind the break become the “Flower wall”, which is used only for Flower and Gong replacements, or for ordinary draws once the main wall runs out.
If the dealer’s roll is a triple, the other three players pay the dealer straight away: 5 for a triple of 2, 3, 4 or 5, and 10 for a triple of 1 or 6.
Dealing
Starting from the wall’s break point, each player is dealt four tiles until 16 tiles have been dealt. The dealer takes a 17th.
Flowers
Any Flower dealt is exposed straight away by the player who receives it and is replaced from the Flower wall, beginning with the dealer and going around until all players have replaced their Flowers.
Taking a turn
On each player’s turn they draw one tile from the main wall and then discard one. Before discarding a player may declare a win from their own draw, declare a concealed Gong, or add a fourth tile to a Pong they have already exposed to make an exposed Gong.
If a player uses a tile for a Gong, they draw a replacement tile from the Flower wall and then discard as usual.
Once the main wall is used up, players draw from the Flower wall.
Claiming a discarded tile
When someone discards a tile, other players may claim it if they can declare any of the following:
Mahjong
The tile completes a winning hand. Any player can claim it, and it takes priority over everything else.
Pong or Gong
A player holds two or three of the remaining tiles. Any player can claim.
Sheung
The tile completes a sequence of numbers. Only the player to the discarder’s right can claim it.
If more than one player claims, the order of priority is Mahjong, then Pong or Gong, then Sheung.
More than one player can win on the same discarded tile.
If a player adds a fourth tile to an exposed Pong, any other player who can win on that tile can take it. This is called robbing a Gong.
Passing on a tile
If a player passes on a tile they could have claimed, they cannot claim that same tile from anyone’s discard until their own turn has come around again.
This includes a winning tile.
Flowers
Flowers are exposed as soon as they are picked up, and are replaced with a tile from the Flower wall. If the replacement is itself a Flower, that one is exposed and replaced too.
The Flower numbers match the seats: 1 is East, 2 is South, 3 is West, 4 is North.
Collecting seven or eight Flowers wins the hand, and Mahjong must be declared only after the replacement tile has been drawn. This “instant Flower win” scores only these points and no other points are added to the hand score.
Chasing
If all four copies of the same tile are discarded before the first discarder’s turn comes round again, whoever discarded the first copy pays every other player 5 points for an Honour tile, 10 for a Suit tile.
West Wind is the exception. A player about to discard the fourth West Wind shows the tile to everyone, returns the tile to their hand and discards something else. No chasing points are paid for West Wind.
Closing a hand
Closing can only be declared on a player’s own turn, after they have drawn and before they discard. It cannot be undone.
From that point the player’s concealed tiles are hidden and frozen. The player cannot look at them anymore, and must discard each tile they draw, unless it is the winning tile. A closed hand is worth 5 points if it wins.
Closing is not allowed with Nico Nico or 16 Orphans hands. Closing and then declaring one of those is a False Mahjong.
Winning a hand
A “self-draw” win is when the winner selects their winning tile from the wall. A “discard win” is when the winner selects it from the discards.
The hand score is what the winning hand is worth (see “Scoring”). Based on the hand score, the following payments are made in the form of points:
Win from self-draw
Each of the other three pays the full hand score to the winner.
Win on a discarded tile
Only the player who discarded it pays the hand score to the winner.
Win by robbing a Gong
The player who declared the Gong pays the hand score to the winner.
More than one winner on a discard
The discarder pays each winner separately based on their hand score.
The minimum score for a winning hand depends on the Wind of the round: 20 for East, 22 for South, 24 for West, 26 for North.
Declaring a win that falls below the minimum is a False Mahjong. The player who declared it pays 25 points to each of the other three and the hand ends.
Points exchanged during play — for Flower bouquets, concealed Gongs, dealer’s triple while breaking the wall, chasing, False Mahjong — move points between players but are not part of a winning hand’s score. Dealer streak points (explained below) do count.
All points received and subtracted contribute towards players’ cumulative points, which are added up across all hands of the game.
How the dealer, seat Wind and round Wind change
The deal moves one seat counter-clockwise each hand, unless the dealer wins alone.
A “dealer streak” is when the dealer wins alone on consecutive hands. The dealer gets 3 bonus points on their second win and 5 on their third win.
The deal passes after the dealer wins three times in a row, if the hand is drawn, or if the dealer wins along with another player.
If a player claims a False Mahjong, the dealer and dealer streak remain unchanged.
Seat Winds are read from whoever is currently dealer, so they shift as the deal moves. The round Wind does not: It advances only when the deal has been all the way round the table, so every round runs at least four hands.
When nobody wins
The hand is a draw when both the main wall and Flower wall are used up.
On a drawn hand every player pays 5 points onto the table. That pool is collected by the next player to win through self-draw, and it builds up if hands are drawn one after another.
