How to Play Mah-jong

By Jaques of London · Est. 1795 · Updated 2026-08-17

Mah-jong is a four-player tile game played with a set of 144 decorated tiles divided into suits, honours, and bonus tiles. Players draw and discard tiles in turn, racing to assemble a complete hand of matched sets and a pair. The interplay between your own draws and the discards of three opponents gives the game a constantly shifting tension that cards alone rarely match.

It is popular in homes, community centres, and clubs across the UK and worldwide. Experienced players value the blend of memory, probability, and reading opponents; beginners find the visual language of the tiles intuitive within a few hands. A session typically runs as a full round of four winds, making it an evening commitment rather than a quick filler.

A little history

Mah-jong as a tile game emerged in China during the latter half of the nineteenth century, most likely in the Ningbo or Shanghai region, though its precise origins are unclear and several competing accounts exist. It spread rapidly across China and reached Western countries in the early 1920s, becoming a fashionable parlour pursuit in Europe and North America. Standardised rule sets were codified during the twentieth century, and in 1998 the International Mah-Jong rules were formalised, though regional variants continue to flourish alongside them.

Setting up

1. Seat four players at a square table, one on each side. Traditionally determine seating and the first dealer by rolling dice or drawing tiles.
2. The dealer is East Wind for the first hand. The other players are, in counter-clockwise order, South, West, and North.
3. Shuffle all 144 tiles face-down on the table. Each player builds a row of 18 tiles, stacked two high, pushing it toward the centre to form a square wall.
4. The dealer rolls two dice. Count that many tiles from the right-hand end of their wall section. Break the wall at that point: tiles to the right of the break form the dead wall (keep 14 aside for the Flower/Kong replacement draws); the rest become the live wall drawn from counter-clockwise.
5. Deal tiles from the live wall. Each player takes four tiles at a time for three rounds (12 tiles each), then the dealer takes two extra tiles and each other player takes one, giving the dealer 14 tiles and each other player 13.
6. Players examine their tiles without revealing them. Flower and Season tiles are set aside face-up immediately and replaced with draws from the dead wall.
7. Play begins with the dealer discarding one tile face-up to the centre.

How to play

1. On your turn, draw the next tile from the live wall. You now hold one more tile than the hand requires.
2. If that drawn tile (or a claimed discard) completes your hand, declare Mah-jong and reveal your tiles. Otherwise, choose one tile to discard face-up to the centre.
3. After any player discards, the other three players may claim it before the next player draws. Claims take priority in this order: Mah-jong (any player, highest priority), Kong (four of a kind, any player), Pung (three of a kind, any player), Chow (sequence, left-hand neighbour only, lowest priority).
4. To claim a discard, say the name of the claim immediately. If two players claim simultaneously and neither is Mah-jong, the player whose turn comes first (in counter-clockwise order from the discarder) wins the claim.
5. When you claim a discard for a Pung or Kong, place the set face-up in front of you (a melded set). Then discard a tile. Your hand is now partially exposed.
6. When the left-hand neighbour claims a discard for a Chow, they form a sequence of three tiles (the claimed tile plus two from their hand), place it face-up, and discard.
7. A Kong (four identical tiles) requires a replacement draw from the dead wall because the hand must always contain the correct number of tiles before discarding.
8. A concealed Kong (all four tiles drawn from the wall, none claimed) may be declared on your turn. Place all four tiles face-down (end tiles optionally face-up for identification). Draw a replacement tile from the dead wall.
9. A flower or season tile drawn from the wall is placed face-up, scored as a bonus, and immediately replaced with a draw from the dead wall before you discard.
10. Tile sets recognised in a winning hand: Chow (three consecutive tiles of the same suit, Characters/Bamboo/Circles only), Pung (three identical tiles), Kong (four identical tiles, counts as a Pung in the hand structure), Pair (two identical tiles, the 'eyes').
11. A complete winning hand consists of four sets (any combination of Chows, Pungs, or Kongs) plus one pair, totalling 14 tiles (not counting bonus Flower/Season tiles).
12. Special winning hands with no sets (Seven Pairs, Thirteen Orphans, and others) are recognised in most rule sets; agree which special hands are in play before the game begins.
13. If the live wall is exhausted before anyone wins, the hand is a draw (goulash). In most rule sets the dealer re-deals and the wind positions do not rotate.
14. When a hand is won, the round ends and scoring takes place before the next deal.
15. The wind positions rotate counter-clockwise after each non-dealer win: South becomes East (dealer), West becomes South, North becomes West, East becomes North. If the dealer wins, the dealer retains East and deals again.
16. A full game is one round of four winds, meaning each player serves as dealer for at least one hand per wind. Many groups play a full four-wind rotation (East, South, West, North rounds).

Winning and scoring

A player wins by declaring Mah-jong with a legal complete hand. Scoring is calculated from a base point value that is then multiplied by doublings. Basic scoring: each tile set and pair carries a point value depending on type and whether it is concealed or melded. Pungs of simples (tiles 2-8) score 2 points concealed, 1 melded. Pungs of terminals (1s and 9s) or honours score 4 points concealed, 2 melded. Kongs score four times the equivalent Pung value. Pairs of Dragons, the player's own Wind, or the round Wind score 2 points; all other pairs score 0. Doublings are awarded for: winning on a self-drawn tile (1 doubling), a fully concealed hand (1 doubling), winning on the last tile of the wall (1 doubling), winning on a Kong replacement draw (1 doubling), Pungs or Kongs of Dragons or Winds (1 doubling each), all Pungs hand (1 doubling), and a clean hand (one suit plus honours, 1 doubling). The base point total is rounded up to the nearest 10, then doubled once for each doubling. Each losing player pays the winner that final score. If the discarder dealt the winning tile, that player pays double and the other two pay single. Many clubs set a maximum payment cap (a limit hand) of 500 points or as agreed. Flower and Season bonus tiles each add 4 points to the winner's score only. Agree on the exact scoring table and any cap before play begins.

The fine points

The most common dispute concerns the priority of claims on a discard. The firm ruling is: Mah-jong beats everything; Kong beats Pung; Pung beats Chow; a Chow claim is only available to the player immediately to the left of the discarder. If a player picks up the next tile from the wall before a claim is declared, that claim is forfeited for that discard. A player who declares Mah-jong incorrectly (a false Mah-jong) must pay a penalty to all three opponents (typically the limit hand value) and their tiles are dead; they draw no more tiles but other players continue.

Robbing a Kong is another disputed area: if a player adds a tile to a melded Pung to make a Kong, any opponent who can use that tile to complete a Mah-jong may claim it, robbing the Kong. The exception is that a Kong completed with a tile drawn from the dead wall cannot be robbed. Regarding Flowers and Seasons: a player who forgets to declare and replace a bonus tile before discarding must keep it if an opponent points it out after the next discard has been placed; house rules vary, so agree the ruling before play.

How to win more often

• Track discards. Every tile placed face-up in the centre is information. If three Bamboo 7s are visible, the fourth is either in a hand or the wall; adjust your own plans accordingly.
• Protect your hand early. A concealed hand scores doublings a melded hand cannot; resist claiming Chows unless you are genuinely close to winning, because each meld you expose tells opponents what to avoid discarding.
• Count your draws. A rough tile count tells you how many draws remain. If the wall is nearly exhausted and you need two tiles to win, consider whether abandoning one set for a faster path makes more sense.
• Respect the winds. Pungs of the round wind and your seat wind each carry a doubling; if you are dealt two of either, holding for a Pung is often worth the slower pace.
• Discard safe tiles first when defending. Honours and terminals you do not need are statistically less likely to complete an opponent's hand early in the round. Once hands are partially revealed, only discard a tile that has already been discarded by someone else, as it cannot then complete a concealed Pung.

Variations

Cantonese Mah-jong

Widely played in Hong Kong and among British Chinese communities, Cantonese Mah-jong uses the standard 144 tiles and broadly similar rules but applies a richer scoring schedule with many more named hand bonuses and doubles. Payment is always by the discarder alone if they deal the winning tile, or by all three losers if the winner draws their own winning tile. A fixed set of special hands (including Heavenly Hand for the dealer and Earthly Hand for others) are recognised and pay at the limit.

Riichi (Japanese) Mah-jong

Riichi Mah-jong is played with 136 tiles (Flowers and Seasons removed) and introduces the Riichi declaration: a player with a closed hand one tile from winning may declare Riichi, place a 1,000-point stick as a wager, and draw only for their winning tile until the hand ends. A rich scoring system based on named patterns called yaku determines hand value in han (doublings) and fu (base points), read off a fixed payment table. A hand must contain at least one yaku to be valid.

American Mah-jong

American Mah-jong diverges significantly from Asian rule sets. It uses 152 tiles (adding eight jokers that may substitute for any tile) and requires players to match hands against an annually published card of valid winning patterns. Chows are not used. This version is common in North American club play and follows rules maintained by the National Mah Jongg League, though that body's specific publications are outside the scope of this reference.

Western Classical Mah-jong

The rule set that spread through Europe and North America in the 1920s and was codified in various Western guides. It uses 144 tiles, recognises Chows, Pungs, and Kongs, and applies a points-and-doubles scoring method close to the system described above. Some editions add a fifth player position using a spare set of tiles, or allow three-player play by removing one suit entirely. This is the version most UK sets are sold to play and is the basis for these rules.
