How to play American mahjong (mah jongg): the full beginner guide

Which mahjong this guide teaches

The game here is American mahjong, also spelled mah jongg: the real four-player game with racks, jokers, and a card of winning hands.

If you were looking for the solitaire tile-matching puzzle, that’s a different game entirely. If you meant Chinese or riichi rules, those variants play differently, and they get a comparison of their own.

The tiles

An American set holds 152 tiles. Three suits run 1 through 9 with four copies of each, which accounts for 108: dots (circles), bams (bamboo sticks, with a bird usually standing in for the 1), and craks (the Chinese numeral over a red character meaning ten thousand).

The other 44 are the honors and the specials: four each of the four winds (16), four each of the three dragons (12), eight flowers, and eight jokers. Each dragon goes with a suit: red with craks, green with bams, and the white dragon, the soap, with dots. The soap works a second job as the digit zero in year hands, and all eight flowers count as one identical tile, which makes them the easiest kong (four of a kind) in the game.

That’s the whole vocabulary. The first skill worth drilling is telling the families apart on sight, because every decision downstream starts there.

The card

You don’t invent your own hand in American mahjong. A card lists every legal winning hand for the season, everyone at the table plays against the same one, and a hand that isn’t on it is worth nothing. The card is organized into sections of related hands: year hands, runs, even numbers, odd numbers, winds and dragons, and the famously unforgiving singles and pairs.

Hands are written in code: digits for ranks, F for flowers, D for dragons, letters for winds, and shapes carrying the suits. Groups sharing a shape are one suit, different shapes mean different suits, and no shape means suit doesn’t matter. Any suit can play any shape, which is why one printed line stands for many concrete hands.

Take this sample line, FF 2026● 4444▲ 4444■, worth 25 and marked X. It isn’t a hand from any real card, just a way to see the code at work. It’s a year hand: a pair of flowers, 2-0-2-6 in one suit with the soap playing zero, and kongs (four of a kind) of 4s in the other two suits. The value is what a win pays, and harder hands pay more. X means you may call discards on the way; C means the hand stays concealed until you win.

Don’t try to memorize hands. Learn the sections well enough to sort every deal into one, and let two or three friendly lines become the ones you can spot on sight. The full notation gets its own guide.

Setup and the deal

Four players sit around the table, and every hand starts with the shuffle: all tiles face down, all eight hands washing them around, a racket the old-timers called the twittering of the sparrows. Each player then builds a wall in front of their rack (the stand that holds their tiles), nineteen tiles long and two high, which accounts for all 152.

Dice pick the dealer, East, and East breaks the wall. The deal runs in bursts: everyone takes four tiles at a time for three rounds, then East takes two more and everyone else takes one. East holds 14 and the other three hold 13. After the Charleston, East starts play by discarding one tile.

Turns move counterclockwise, walls push out as they empty, and there is no dead wall: every tile not in a hand is drawable, so the wall count only ever falls.

The Charleston

1. 1Right
2. 2Across
3. 3Left

Before any turns, the table trades away its junk. The first Charleston is mandatory and unstoppable: three tiles to your right, three across, three to your left, each pass face down and all three at once. If every player agrees, a second round runs mirrored (left, across, right), and one refusal kills it with no reason owed. Last comes the courtesy pass: you and the player across each offer up to three tiles, and the smaller number is what crosses.

Two passes allow a blind steal: the first round’s left pass and the second round’s right pass. Pass fewer of your own and top up, sight unseen, from the tiles arriving. Jokers never travel in any pass, ever.

As for what to send: pass suit-scattered loners, keep pairs (jokers can’t make them and discards can’t be called for them), and hold flowers until you know your line. Then read what arrives, because three bams in a row from your right neighbor is your right neighbor telling you what they don’t want, and that’s information.

Turns and calling

Your turn is draw one, throw one: take the wall’s next tile, then discard one face up, naming it aloud. The name matters legally, because calls hang on it, and a misnamed discard that costs someone a mahjong costs the misnamer dearly. Once a discard is down it’s dead history, and only the newest one is live.

A live discard can be claimed by anyone until the next player racks their draw, and racked means racked. Claim it to complete a pung (three identical), kong (four), or quint (five), which goes face up on top of your rack with the rest of the group coming from your hand, jokers welcome. That face-up group is an exposure.

Pairs can never be called, except when that tile wins you the game. When two players want the same discard, mahjong beats any exposure, even one already in progress, and between exposure claims the seat nearest after the discarder wins.

Call sparingly: every exposure spends your secrets and your flexibility, and eager early calls top every list of beginner mistakes.

Jokers

A joker stands in for any tile inside a group of three or more identical tiles, and nowhere else: never in a pair, never as a single, never as a lone wind or a year digit, and never passed in the Charleston. That one sentence is most of joker law, and singles and pairs hands pay more than most precisely because jokers can’t touch them.

The other half is the exchange. On your own turn, after drawing and before discarding, you may redeem any exposed joker on the table, yours or an opponent’s, by handing over the real tile it stands for. The trade can’t be refused, it doesn’t count as exposing (so even concealed hands may redeem), and it wins endgames.

Two cautions: a discarded joker is dead the moment it hits the table, and a hand that wins without any jokers doubles its value (except a singles and pairs hand, which can never hold one).

Winning and payouts

Match all 14 tiles of a card hand exactly, say mahjong, and lay the whole hand out in the card’s order for the table to verify. Thirteen of fourteen pays nothing; there is no second place.

The win pays the hand’s printed value: the thrower of your winning tile pays double while the others pay face value, a self-picked win collects double from all three, and a jokerless hand doubles once more on top. Singles and pairs hands skip that last double, since no joker could ever sit in them.

Dead hands and wall games

Hands can also die. Wrong tile count, an exposure that fits no line on the card, a joker seated in a pair: any of these kills the hand, and only opponents may point it out (a wrong accusation costs the accuser instead). A dead player stops drawing but keeps paying, and their exposed jokers stay redeemable.

If the wall empties with no winner, that’s a wall game: nobody pays, the tiles get shuffled, and the deal moves on.

Defense

Beginners chase their own hand; players also watch everyone else’s. The pond, the face-up discards in the middle of the table, is public memory: only four of each tile exist, so when three 5 dots are face up and your line needs a pair of them, that line is finished no matter how pretty it looks in your rack. Count before you chase.

Watch the exposures too. Whatever line an opponent is chasing must use those exact groups, and two exposures usually narrow the card to a line or two, which tells you what not to throw. Late in a hand, the safest discards are tiles no exposure points toward and tiles the pond already shows three of (only a pung filled out with two jokers can still take that last copy); hot ones are fresh tiles in an exposed player’s suit.

When you’re four tiles from mahjong and somebody else is one call away, the strongest move on the table is breaking your own hand: stop feeding, throw safe, and let the wall run out. Nobody pays on a wall game, and that beats paying a winner.

Table manners, briefly

The etiquette is short and it’s real: never touch another player’s tiles or rack, name every discard at table volume, announce joker exchanges before they happen, and keep quiet about live hands, which means no coaching and no commentary. Decide your discard before your turn comes; the table’s patience runs about ten seconds. Win gracefully, pay promptly, and settle disputes with the card, not volume.

Every table also runs a few house rules, and the veterans owe the beginners a list of which rules those are before the first deal, not after.
