Once the tiles are dealt, mahjong runs on a single loop: on your turn you either claim the tile just discarded or draw a fresh one from the wall, and then you discard. Play moves counter-clockwise, and the loop repeats until somebody completes four sets plus a pair and calls mahjong. Every other rule in the game is an exception layered on top of that loop.
One loop, four seats
The dealer holds fourteen tiles and everyone else holds thirteen, so East never draws to begin. East picks a tile, places it face up in the middle of the table and announces it, and that opening discard starts the hand.
The turn then passes to the player on East’s right and keeps travelling counter-clockwise. Every legal action on your turn falls into one of six categories, and reading them once answers most rules questions before anybody asks them.
| Action | What you need | Tile comes from | Turn order |
|---|---|---|---|
| Draw | Nothing — the default | Live end of the wall | Unchanged |
| Chow | Two tiles forming a run with the discard | Left-hand neighbour only | Unchanged |
| Pung | Two identical tiles in hand | Any player’s discard | Jumps to the caller |
| Exposed kong | Three identical tiles in hand | Any player’s discard | Jumps to the caller |
| Concealed kong | Four identical tiles, none claimed | Your own draws | Unchanged |
| Mahjong | A complete hand | Draw or any discard | Hand ends |
Whichever route you take, the turn finishes the same way: with a discard. The only turn that ends without one is the winning turn.
What a finished hand looks like
Four sets and one pair wins, and a set means three identical tiles, three consecutive tiles of the same suit, or four identical tiles. Wikipedia’s overview of mahjong gives that same four-sets-and-a-pair shape as the standard structure across the regional variants.
To win, declare mahjong out loud and turn your tiles face up so the table can verify them. The winning tile may come from your own draw (a self-drawn win, which scores extra in most systems) or from any player’s discard.
When you need only one more tile you are waiting, or holding a ready hand. Strong opponents often work out who is waiting from the pace and safety of the discards, well before anyone declares anything.
Declaring in error carries a price. Most house rules penalise a false mahjong with a payment to each opponent, and stricter tables retire the offending hand for the rest of the round.
When two players want the same tile
Simultaneous claims happen constantly, so precedence is fixed rather than argued about:
- A call to win the hand outright
- Kong
- Pung
- Chow
The Mahjong Competition Rules played at European Mahjong Association tournaments use the same order, so it is worth learning as written rather than as a house preference. Where two players claim the same tile to win, the one seated nearest the discarder’s right takes it, though some tables pay both, which is a thing to agree on before it comes up.
The three claims and what each one demands
Chow — a run of three
A chow is three consecutive tiles in one suit, such as 3, 4 and 5 Circles. It is the only claim with a positional restriction: you may take it solely from the player on your left, the person who plays immediately before you.
Because nobody is skipped, play carries on in the normal order. That makes the chow the quietest claim at the table.
Pung — three of a kind
Hold two 5 Bamboo, and the moment any player discards a third you may call pung. Say it before the next player touches the wall, take the tile, lay the set face up where everyone can see it, and discard.
Play then resumes to your right, so anyone sitting between the discarder and you simply loses that turn. Nobody is owed compensation for it.
Kong — four of a kind
Three matching tiles in hand plus a fourth from any discard makes an exposed kong. Because a kong occupies four tiles but counts as one set, you take a replacement tile from the tail of the wall before discarding, which keeps your hand the right length.
A kong you complete from your own draws can stay face down as a concealed kong, which is usually worth more. You may also add a self-drawn fourth tile to a pung you have already exposed, but you may never use a discard to upgrade an exposed pung.
Why the pair is treated differently
Every standard winning hand needs exactly one pair, and it cannot be claimed from a discard except on the tile that completes the hand. If you want the vocabulary in one place, our glossary of common mahjong words every player should know is the fastest reference.
Claiming is speed bought with information
Beginners tend to claim everything they legally can, which is the quickest route to a cheap hand. Every exposed meld also tells three opponents what you are collecting, and it locks those tiles in place — a concealed set can be broken up and repurposed later, an exposed one cannot.
Many scoring systems reward concealed hands and set a minimum value before you are allowed to win at all, so a hand assembled entirely from claims can be technically complete and still worth nothing. Our guide to basic scoring hands in mahjong shows which patterns actually pay.
The calculation changes completely in American mahjong. The National Mah Jongg League issues a card each year that defines every legal hand, and there is no chow in that game at all: a discard may be claimed only for a pung, a kong or the winning tile.
Replacement draws: flowers, seasons and concealed kongs
Two things are settled before East’s opening discard, in seat order starting with East and moving counter-clockwise. Both hand a player an extra draw from the tail of the wall.
Flowers and seasons. If you were dealt one, lay it face up in front of you and take a replacement tile. If that replacement is itself a flower or a season, declare it and draw again.
These tiles score points but never form melds, so they sit outside your thirteen. The same replacement rule applies every time you draw one later in the hand.
Concealed kongs. A player dealt four identical tiles may declare the kong immediately, keep it face down in front of them, and draw a replacement. If the deal itself is still unfamiliar, our walkthrough of how to set up and deal a mahjong game covers seating, the wall and where the tail sits.
A hand in motion
- East discards 9 Characters. Nobody claims it.
- South draws from the wall and discards West Wind.
- West holds two West Winds, calls pung, exposes the set and discards 2 Circles.
- Play resumes with North, who loses nothing this time because North sits to West’s right anyway.
- North holds 3 and 4 Circles and West is the left-hand neighbour, so North calls chow, exposes 2-3-4 Circles and discards 7 Bamboo.
- Play continues to East, who draws a flower, lays it face up, takes a replacement from the tail and discards as normal.
Four mistakes that show up in the first few games
- Calling chow across the table. Runs can only be claimed from the player on your left.
- Forgetting the replacement draw after a kong. Skip it and you play the rest of the hand a tile short.
- Calling too late. Once the next player has drawn, the discard is dead.
- Claiming a pair. Only legal on the tile that completes your hand.
A wider list lives in our rundown of the mistakes new mahjong players make and how to avoid them.
Rules questions that come up mid-hand
Does a pung skip players?
Yes. Play restarts from the caller, so anyone sitting between the discarder and the claimer loses that turn. A chow never skips anyone, which is one reason chows keep a hand moving quietly.
Can I take back a discard?
No. Once a tile touches the table face up it belongs to the game, and any player may claim it under the normal priority rules.
What happens when the wall runs out?
The hand is a washout. No one scores, the tiles are washed and rebuilt, and most house rules let the same dealer keep the deal for the replay.
Do I have to claim a tile I can use?
Never. Claiming is always optional, and passing on a tile to keep your hand concealed or your options open is a legitimate strategic choice.
How long does one hand take?
A hand between four players who know the rules usually runs a few minutes, and a full round takes considerably longer once scoring and seat rotation are included.
Learn the loop by playing it
Reading the loop takes ten minutes; internalising it takes roughly three hands with four people and a real set. If you are in Sydney and short of equipment, we deliver tiles, tables and stools across Greater Sydney and hold pickups at Wolli Creek — the hire options list what comes with each one.
