How to Play American Mahjong

By the end of this guide you will know exactly what to do when the turn reaches you. It takes about six minutes to read.

The one thing

A turn is one small loop — draw, decide, discard — and the whole game is that loop going around the table.

Why this matters at the table

New players brace for something complicated and get something small. A turn has three steps and usually takes under ten seconds. Almost all first-game anxiety comes from not knowing that, and from imagining a turn as a puzzle to solve rather than a habit to repeat. Learn the loop and you can sit at any table today, even without knowing much else.

Picture it

Stand behind a player's shoulder for one turn. Her neighbor sets a tile down and names it. She reaches to the wall, slides one tile off the end, and turns it up where only she can see it. Two seconds. She slots it into her rack, pulls a different tile out, sets it on the table, and says its name. The person to her right reaches for the wall. The whole thing took about eight seconds, and she never stopped talking.

The loop, in three steps

When the turn comes to you:

  1. Draw one tile from the end of the wall.
  2. Decide whether it helps the hand you are building.
  3. Discard one tile face up in the middle, and say its name out loud.

You always end your turn with the same number of tiles you started with. One in, one out. If the tile you drew is no use, the tile you drew is the tile you discard, and that is a completely ordinary turn.

Then the turn passes one seat to the right, and the next player does the same three things.

Say your discard out loud

Naming the tile you discard is not decoration. It is how the table stays in sync.

Other players are listening for particular tiles. Saying the name gives everyone a fair chance to react before the next person draws, and it keeps a table moving without anyone leaning over to squint.

If you forget, someone will ask. If you cannot remember the name of the tile in your hand, hold it up. Nobody minds.

The turn can jump

Here is the one wrinkle in an otherwise straight loop.

Any player can claim the tile you just discarded if it completes a group they can show immediately. When somebody does that, play does not rewind — it continues from the person who claimed it. Players between the discarder and the claimer simply get skipped.

So the turn usually moves one seat to the right, and occasionally leaps across the table. That is normal, and it is why you watch every discard rather than only your own turn. Claiming is covered in Calling Tiles and Making Exposures.

The hand ends in one of two ways

The loop keeps going until either somebody completes a full pattern from the card and declares it, or the wall runs out of tiles and nobody has won. Both are covered in How a Hand Is Won.

Then the tiles go face down, and the table sets up again.

Watch one hand of thinking

Here is a real turn, narrated at the speed it actually happens.

The tile comes off the wall. It is a tile I do not need — I am collecting in one suit and this is not it. Decision made in about a second.

Now the only real question of the turn: what do I throw? Not the one I just drew, automatically. I glance at my rack for my worst tile, which today is a lone wind that has had no company for six turns. The wind goes. I say its name.

That is it. I did not calculate anything. I asked "does this help?" and then "what is my worst tile?" — and those two questions cover almost every turn I will take all afternoon.

Some turns are harder. Maybe one in eight. On those I take an extra five seconds, and nobody minds, because everybody at the table has those turns too.

When it goes sideways

The most common beginner mistake is trying to learn the whole game before taking a single turn. People sit down determined to understand jokers, exposures, and the card all at once, and then freeze on a turn that only ever needed three steps.

Take the turn. Draw, decide, discard. You can play an entire hand knowing nothing else, and you will learn more from four real turns than from four pages.

If you lose the thread mid-hand, there is one sentence that gets you back in: "Where are we?" Ask it. Somebody will point at the wall, tell you whose turn it is, and the game carries on.

Table words

Check yourself

  1. What are the three steps of a turn, in order?
  2. You draw a tile that is no help at all. What do you do?
  3. Why does every player say the name of the tile they discard?
Answers
  1. Draw, decide, discard.
  2. Discard it. That is an ordinary turn, not a wasted one.
  3. So every player has a fair chance to claim it before the next person draws.

Homework

Five minutes, no tiles. Say the loop out loud twenty times: draw, decide, discard. It sounds silly and it works. The goal is for the sequence to arrive without thinking when you are nervous. Done when: you can say it without hearing yourself think.

At home. Deal yourself thirteen playing cards and put the rest face down as a draw pile. Take twenty turns: draw one, decide, discard one, and say the discard out loud. Aim for under ten seconds a turn. Done when: you have taken twenty turns and the last five felt automatic.

At a table. Watch one full hand from behind somebody's shoulder before you play. Count how many seconds an average turn takes. It will be fewer than you expect, and that number is the thing that calms people down. Done when: you can say the average out loud.

Bring back. From The Charleston: name both passing sequences, in order.

You are ready when

Take it to a table

Next, learn how to claim a discarded tile in Calling Tiles and Making Exposures. To find out how the loop finally stops, read How a Hand Is Won.

The loop takes one hand to learn at a real table. Book a lesson or Open Play seat and take twenty turns.

Questions people ask

Which direction does play go? One seat to the right, every turn, unless somebody claims a discard and the turn jumps to them.

What if I take too long on my turn? Take the time you need. Tables absorb a slow turn without comment. What actually disrupts a table is a player who stops paying attention between turns, not one who thinks carefully during theirs.

Can I pick up a tile somebody discarded earlier? No. Only the most recent discard can be claimed, and only before the next player draws. Once the next tile comes off the wall, the moment has passed.

How many tiles do I hold? The same number all game. You draw one and discard one every turn, so your hand size never changes until you win.
