How to Set Up an American Mahjong Game: A Beginner's Walkthrough
Everything before the first discard has a fixed script, and it is the same script at every table in America. Learn it once and you can sit down anywhere. Here is the whole setup, in order, with the numbers that belong to a standard American set.
Before anyone sits down
You need four players, a table each can reach the middle of (36 to 40 inches square is comfortable), and the current year's NMJL card within everyone's reach. A playing mat is not required, but it quiets the tiles and keeps the walls from skating on a polished table — our mat guide explains why regulars insist on one.
Step 1: Wash the tiles
All 166 tiles go face down in the middle, and everyone pushes them around with both hands in wide circles for half a minute. This is called washing. It is louder and more chaotic than shuffling cards, and that noise — tiles clicking against each other — is the sound mahjong people mean when they say the game feels like home.
Step 2: Build the four walls
Each player builds a wall in front of their rack: 19 stacks side by side, two tiles high (38 tiles), face down, pushed into a neat row. The four walls form a square in the middle of the table, corners touching. If your square looks lopsided, someone miscounted — count the stacks, not the tiles.
Step 3: Roll for the dealer
Each player rolls two dice once; highest total becomes East, the first dealer. Going around the table to the right, the others take South, West and North. The deal rotates counterclockwise after every hand, which is why the wind indicator lives on the table.
Step 4: Break the wall
East rolls the dice again. The total tells you where to open the wall:
- Count that many players counterclockwise around the table, starting with East — that player's wall is the one to break.
- On that wall, count the same number of stacks from the right end, and lift those stacks off to the side.
- The break is now the start of the draw wall. The stacks you lifted go on top of the far end, and the game will draw from beside the break.
It feels like ceremony the first time and takes five seconds by your fifth game.
Step 5: Deal
Starting with East, each player takes two stacks (four tiles) at a time from the wall, going counterclockwise, until everyone has 12. Then each player takes one more, and East takes a fourteenth. Every player: 13 tiles. East: 14 — because East discards first.
Step 6: Rack and read
Stand your tiles on the rack, sorted by suit, winds and dragons grouped, flowers and jokers parked at one end. Now open the NMJL card and start asking the only question that matters at this point: which section does my hand look like? You are not choosing a hand yet — just noticing what you have more of. If the card is still a wall of text to you, print our beginner rule card and keep it next to your rack; it compresses the setup and turn order onto one A4 page.
And if you want to watch all of this happen first, the free practice game washes, builds, breaks and deals automatically — play two games just to observe the rhythm, then try it with real tiles.
Quick Answers
How many tiles does each player start with in American mahjong?
Thirteen each; the dealer (East) starts with fourteen and discards first. Walls are built 19 stacks wide, two tiles high — 38 tiles per player from a 166-tile set.
Which direction does play go in American mahjong?
Counterclockwise. The dealer sits East, the player to their right is South, and both the deal and the turn order travel to the right around the table.
Do I need the NMJL card to set up a game?
You need it to play, not to set up — but put it on the table before the deal. The card changes every year; the 2026 card is valid through March 31, 2027.
How big a table do I need for American mahjong?
Comfortable play starts at about 36 inches square; 40 is the sweet spot with racks and a mat. Round tables work too — add about 18% to the diameter.
