How to Set Up American Mahjong: The Wall, the Deal & Who's East

Setup is where new players feel the most lost, but it's really four steps: mix, build, pick East, and deal. Each takes seconds once you've done it. Here's the whole sequence, in order.

Step 1: Mix the tiles

Put all 152 tiles face-down on the table and mix them thoroughly with your hands — everyone helps. That satisfying clack is your shuffle.

Step 2: Build the four walls

Each player builds one wall in front of their rack: 19 tiles long, 2 tiles high. Four walls of 38 tiles each is exactly 152 — the whole set. Unlike Asian versions of the game, American Mahjong has no dead wall: every tile is playable, and you draw until the wall is empty or someone wins.

Step 3: Choose East

There's no dealer in American Mahjong — one player is East. East breaks the wall, draws first, starts with an extra 14th tile, and makes the first discard. To choose East, each player rolls the dice and the highest roll takes it (re-roll ties). Some casual groups simply make the host East — a common shortcut, though not the official rule. After each hand, East rotates to the right, no matter who won.

Step 4: Break the wall

East rolls two dice, adds them up, and counts that many stacks (2-high columns) in from the right end of their own wall. The counted tiles stay by East's rack; the rest of the wall gets pushed toward the center. Dealing starts where the count stopped, moving left. (Some casual tables skip the break and deal straight from the end of East's wall — follow your group's style.)

Step 5: The deal

Each player takes their own tiles, moving counter-clockwise — East first, then right, across, left:

• Rounds 1–3: each player takes 4 tiles at a time (2 top, 2 bottom) — everyone now has 12
• Final round: East takes the 1st and 3rd top tiles; the other three players take 1 tile each
• Result: East has 14 tiles, everyone else has 13
• When a wall runs out mid-deal, the player to the left pushes theirs out and dealing continues

Keep your dealt tiles face-down until everyone has theirs, then the whole table racks together.

Then the game starts

After the Charleston (the tile-passing ritual that comes next), East — already holding 14 tiles — skips the draw and simply discards one tile, naming it aloud. That first discard is the official start of the game.
