How to Play American Mahjong: A Complete Beginner's Guide

American Mahjong is a four-player game with one simple goal: be the first to collect 14 tiles that exactly match a hand printed on the National Mah Jongg League's annual card. Everything else — the tiles, the passing, the calling — serves that race. This guide walks the whole game, start to finish, in plain language.

What you need

Three things: an American Mahjong tile set (152 tiles, including Jokers), a current NMJL® card, and three or four players with racks. Four is standard, but the game plays fine with three. You'll want the current year's card to play the current hands, though an older card is perfectly playable as long as everyone at the table uses the same one.

The tiles

An American set has 152 tiles: three suits (Bams, Craks, and Dots, each numbered 1–9), four Winds (North, East, West, South), three Dragons, eight interchangeable Flowers, and eight Jokers. Jokers are the wild tiles — they can stand in for any tile in a group of three or more identical tiles, but never for a pair or a single. (Eight Jokers, by the way, is the quick giveaway that a set is American rather than Chinese.)

The card — your menu of hands

Every winning hand must match one complete line on the current NMJL® card. You can't invent your own combinations — the card defines exactly what counts, and it changes every year. It uses a compact shorthand of colors, numbers, and letters, so learning to read it is the single most important beginner skill. The good news: you're learning categories of hands, not memorizing a list — once the shorthand clicks, any card reads the same way.

Setting up: roll, break, deal

Everyone rolls the dice to decide who's East (the dealer for the hand). East rolls again to "break the wall" — pick where the deal starts. Then players take their own tiles, moving to the right: 13 tiles each, except East takes 14 and opens the game with a discard. A handy rule of thumb: deal and play to the right, but build and push out the walls to the left.

The Charleston

Before play begins, players pass tiles in a ritual called the Charleston — your chance to trade away tiles that don't fit your plan. The first Charleston (three tiles right, then across, then left) is required. A courtesy pass with the player across from you can follow, and then an optional second Charleston (left, across, right) — but once the second one starts, it must be completed. Short on tiles you're willing to give? The left pass (and the final right pass) can be a "blind pass" of tiles you just received, unseen. You can never pass a Joker, and a hand is never declared dead during the Charleston.

Taking a turn

Play moves to your right (counter-clockwise). On your turn you draw one tile from the wall, decide whether it moves you closer to your hand, then discard one tile face-up in the center and say its name aloud. You always hold 13 tiles — 14 only in the moment between your draw and your discard. Pause a beat after naming your discard, because that's the window for anyone to claim it.

Calling a discard

If a discard completes a group of three or more identical tiles your hand needs — a pung (three), kong (four), or quint (five) — you can "call" it instead of waiting to draw. You take the tile, expose that whole group face-up on your rack, and then discard. A call jumps the turn order: anyone who was between the discarder and you gets skipped, and play resumes to your right. Two things to know: an exposed pung is locked (it can never grow into a kong later), and the window to call closes the moment the next player commits to their turn.

Jokers and the Joker swap

Jokers substitute for any tile inside a group of three or more of the same tile (pung, kong, quint), but never for a pair or a single — including the NEWS and Year singles in Singles & Pairs hands. On your turn, you can swap a real tile from your hand for a Joker sitting in any player's exposed group — yours or an opponent's — as long as you hold the exact tile it's standing in for. One caution: a discarded Joker is dead for good; no one can ever call it.

Winning the hand

When your 14 tiles exactly match a line on the card, you win — but say "Wait" first and check that your hand really is on the card, because a false call is costly. Only when you're sure do you claim the tile and declare "Mahjong!" Unlike every other call, a winning call has no discard — the tile completes your hand and the hand ends right there. Then you expose your whole hand face-up so everyone can verify it against the card.

Scoring: who pays what

Each hand on the card has a printed dollar (or point) value. How you won decides the payout: win off another player's discard and the discarder pays double while the other two pay the single value; win off your own draw (a self-pick) and all three players pay double. On top of that, a winning hand made with no Jokers doubles the whole payout — a real bonus to aim for. (Singles & Pairs hands are naturally jokerless, so they don't get the extra doubling.)

Common beginner mistakes

• Losing count — you should hold 13 tiles (14 only between your draw and discard); ending a turn at 12 or 14 is a problem
• Calling a tile you can't legally use, or exposing the wrong group — that can kill your hand for the round
• Trying to pass a Joker in the Charleston — you never can
• Forgetting to say your discard out loud, so no one hears their chance to call
• Abandoning a hand that's nearly complete because a shinier one caught your eye
