How to Play American Mahjong: Complete Beginner Guide

American Mahjong Is a Different Game

American mahjong uses the same tiles you have seen in Chinese mahjong, and almost none of the same rules. In the Chinese game you win by building four sets and a pair. In the American game you win by matching one exact hand printed on a card that the National Mah Jongg League reissues every spring — and if your fourteen tiles do not match a line on that card, they are worth nothing at all.

Three things separate the two games. The card decides what is legal this year. Jokers, eight wild tiles that exist in no other variant, stand in for tiles inside a group of three or more. And the Charleston — a round of passing tiles before the first draw — lets every player steer their hand before luck takes over. Everything else in this guide grows out of those three.

The Tiles: 152, Not 144

An American set holds 152 tiles. The numbered tiles are the same as everywhere else: three suits — craks (characters), bams (bamboo) and dots — each running from one to nine with four copies of every tile, 108 in total. American players almost always use the short names, so a "three bam" is what a Chinese player calls a three of bamboo. The suits are colour-coded on the tile faces themselves — characters in red and black, bamboo in green, dots in a mix of blues and reds — but the colours printed on the card mean something else entirely, and mixing the two up is a standard first-week mistake.

The count changes in the honours. Sixteen winds (four each of East, South, West and North), twelve dragons (four Red, four Green, four White), eight flowers and eight jokers. Sixteen plus twelve plus eight plus eight is forty-four, and 108 plus 44 is 152 — the jokers are the eight tiles a Chinese set does not have at all.

Two of those tiles change how the game feels. Flowers are not set aside and scored the way they are in Chinese play; they are passed during the Charleston and used inside the hands that call for them. And jokers are wild, but only inside groups. There is also no chow in American mahjong — no runs of three consecutive tiles. Chinese players reach for that move by habit in their first American game, and it is not there. What replaces it is the quint: five identical tiles in a single group, a shape that cannot be completed without jokers and that gets its own section of the card.

You Cannot Win Without the Card

Every spring the National Mah Jongg League publishes a new card, and every spring it is different. A card lists somewhere between 65 and 75 legal hands, grouped into sections by theme — the year itself, 2468, Quints, Consecutive Run, 13579, Winds and Dragons, 369, and Singles and Pairs. You may build any hand on that card. You may build nothing else. The card is published by the league and sold each spring rather than shipped with any set, which is why a second-hand set on a resale site so often has everything except the one thing you actually need.

Read a line the way you read a recipe. Numbers are literal, with one exception: a zero stands for the White Dragon, which American players call the soap. The letter F is a flower and D is a dragon. Colour carries meaning — two tiles printed in the same colour must come from the same suit, and two tiles in different colours must come from different suits. You choose which suits to use, and that choice is most of your strategy.

This is why American players say the game is relearned every year. A hand that was legal last April may not exist this April. For your first session, do not try to learn the card. Pick two lines that use three or four groups, prop the card next to your rack, and play only those.

The Charleston: Three Passes Before Anyone Draws

Before the first draw, every player passes tiles. The first Charleston is mandatory and always runs in the same direction: three tiles to the player on your right, three across the table, three to the player on your left. Nine tiles leave your hand and nine arrive before a single tile is drawn from the wall. In practice you pass the three tiles that fit nothing you are holding, and you hope the nine coming back are less random than the nine going out.

A second Charleston may follow in the reverse direction — left, across, right — but any player may stop it, and in most groups someone does. During that second pass you may also make a blind pass, sending on tiles you have just received without looking at them, which helps when everything you have been handed is wrong for the hand you are chasing.

One rule catches everybody: jokers cannot be passed. They stay in your rack through the whole exchange. After the Charleston you and the player opposite may agree a courtesy pass of up to three tiles, and that number is negotiated rather than fixed — you may ask for three and receive none. The Charleston exists only in American mahjong, and it is the reason two players who start with similar tiles can end up in completely different hands.

Setting Up: Walls, Dice and Racks

All 152 tiles go face down and get shuffled, then each player builds a wall in front of their rack — nineteen tiles long and two tiles high, 38 to a side. Dice decide who is East, and East rolls again to decide where the wall is broken. Two dice produce the total, and that total fixes both who deals and where the wall is broken. Online it happens without you noticing; in person it is the moment everyone leans in to check the count.

Tiles are dealt from the broken wall in fours. East ends up with fourteen and everyone else with thirteen, and each player stands their tiles on a rack with the faces toward them. The rack is not decoration: it keeps a hand private in a game whose tiles are tall enough to be read from across the table.

East discards first, and play then moves counter-clockwise around the table. A turn is a draw and a discard, exactly as in Chinese mahjong. What differs is what you are allowed to do with the tiles other people throw away, and that is where the game turns.

Jokers: Where They Fit and Where They Never Fit

A joker is a wild tile, and it is the most misused tile in the game. It can stand in for any tile you need inside a group of three or more — a pung of three, a kong of four, a quint of five. Where a hand offers you a choice of suits, the joker takes whichever suit you choose.

What a joker cannot do is just as firm. It cannot stand in for a pair. It cannot stand in for a single tile. It cannot be used inside NEWS, the grouping of one of each wind, or inside the year numbers, because those groupings are about specific tiles rather than interchangeable ones. This one restriction kills more beginner hands than any other rule, because a pair looks exactly like a group that is one tile short. Picture two Red Dragons in your rack with a joker beside them. That is a pair plus a spare tile, not a pung — and if you lay it down as one, you have exposed a group the card does not recognise.

There is one escape hatch, and you should know it before somebody uses it on you. If a player exposes a group containing a joker, any player may swap for it: you hand over the real tile the joker is standing in for, add one extra tile from your hand as compensation, and the joker comes to you. You cannot take a joker out of a group just to keep it. The swap has to be paid for.

Exposing a Hand: Calling and the C on the Card

You may claim a discard to complete a group of three or more, and you must then lay that group face-up on your rack. You cannot claim a discard to make a pair — with one exception, which is claiming the tile that wins the hand outright.

Every hand on the card is marked either X or C. X means exposed: you may call discards freely while building it. C means concealed: you may not call anything except the tile that completes your hand, and the rest stays hidden on your rack until the end. Concealed hands are harder to finish and they pay more. The gap is deliberate: a C hand cannot be fed by the table, so the card pays you for building it blind.

Exposure is a commitment, not a convenience. The moment you lay a group down it is fixed, the table can see what you are chasing, and any joker inside it becomes available to whoever wants to pay for the swap. If that group turns out to belong to no line on the card, you have not simply given away information — you have killed the hand.

Dead Hands and the Two Ways Beginners Reach Them

A dead hand is a hand that can no longer win, whatever you draw. It happens when the tiles you have exposed match no line on the card, or when your hand holds the wrong number of tiles. A dead hand keeps drawing and discarding until somebody else wins, but it cannot win itself.

Beginners reach a dead hand the same two ways almost every time. The first is exposing a group that fits no line — usually because two lines were being chased at once and the group belonged to neither. The second is declaring a win with the wrong count: fourteen tiles for most hands, more for hands built on kongs or quints, and a hand that is one tile off is simply a hand that has not won.

The cure is boring and it works. Before you lay a group down, put a finger on the line you are building and read it back. If the group is on that line, expose it. If you cannot find it in three seconds, do not. Experienced players do this without thinking, which is why they rarely go dead. And if you do go dead, the hand is not over — you keep drawing and discarding, and your job becomes making sure nobody wins off you. A dead hand that folds safely costs you nothing but time.

Scoring: Who Pays What

Every hand on the card carries a value, and the values run from roughly twenty-five to roughly seventy-five. That number is the size of the pot for that hand. The card decides it — not how well you played.

Only three things change what each player actually pays. Who threw the winning tile. Whether you drew it yourself. And whether your hand is jokerless.

Win on a discard and the player who threw it pays double while the other two pay face value. Draw the tile yourself and every player pays double. The total settles between you and each opponent rather than out of a central pot, which is why American players keep score on a slip of paper instead of stacking chips. Run it once and the shape of the game becomes clear: a thirty-point hand won on a discard pays sixty from the thrower and thirty from each of the other two, a hundred and twenty in total. Win the same hand on your own draw and all three opponents pay sixty, which comes to a hundred and eighty.

A jokerless hand — one built with no wild tiles at all — doubles what every opponent pays, except in the Singles and Pairs section, where jokers are barred anyway and the bonus would mean nothing. If the wall runs out before anyone completes a hand, that is a wall game: nobody wins, nobody pays, and the deal passes on.

Your First Session

Set the card where you can see it and pick two X hands that use three or four groups. X hands let you call tiles, which keeps the game moving while you learn. Ignore the point values on the first night and ignore Singles and Pairs completely — those hands are hard, and jokers are banned inside them. If you are learning alone, pick hands you can picture finishing in five turns. If you are learning at a table, say your target hand out loud for the first few deals — hearing a hand named is how most American players learned the card in the first place.

Play three or four hands before you decide anything about the game. The Charleston will feel chaotic for two of them, you will probably expose a group you should not have, and the card will take longer to read than you expect. After one evening it stops being a puzzle and becomes a shape you recognise.
