How to Set Up an American Mahjong Game: A Beginner's Step-by-Step Guide
From counting the 152 tiles to building the walls, choosing East, and dealing the opening racks — everything you need to prepare a table for your first game of American Mahjong.
Setting up an American Mahjong game is a short, repeatable routine: gather the equipment, mix the tiles, build the walls, choose the dealer, deal the racks, and get ready for the Charleston. Once you've done it a few times, it takes just a few minutes.
This guide walks through every step, with the correct tile counts, wall dimensions, and dealing numbers verified against standard American Mahjong practice.

1. What You Need to Play
Before you can set up a game of American Mahjong, gather the essentials. You don't need much, but each item plays a specific role in getting the table ready.
- Four players. American Mahjong is a four-player game. Each person sits at one side of a square table.
- A standard American Mahjong tile set. The set contains 152 tiles (see the next section for the full breakdown).
- Four racks. Racks hold your tiles upright and conceal them from other players. Many racks include a built-in pusher that helps move tiles onto the table cleanly.
- The current National Mah Jongg League (NMJL) card. This annual card lists every valid winning hand for the year. Each player needs access to a current card.
- Dice. Dice are used to choose the dealer and to determine where the wall is broken for dealing.
- A suitable playing surface. A square table with a felt or cloth surface helps keep tiles from sliding.
Beginner Tip
Racks and pushers are common accessories that make the game easier and tidier — they are not separate categories of tiles. A pusher simply helps you slide tiles forward without disturbing your rack.
2. Understand the 152-Tile Set
A standard American Mahjong set contains exactly 152 tiles, divided across seven categories. Knowing this breakdown helps you confirm your set is complete before you begin.
| Category | Tiles | What's included |
|---|---|---|
| Bams | 36 | Four copies of each number 1–9 |
| Craks | 36 | Four copies of each number 1–9 |
| Dots | 36 | Four copies of each number 1–9 |
| Winds | 16 | Four each of East, South, West, North |
| Dragons | 12 | Four each of Red, Green, White |
| Flowers | 8 | Eight unique Flower tiles |
| Jokers | 8 | Eight Joker tiles |
| Total | 152 | Standard American Mahjong set |
Some commercially sold sets include extra replacement or blank tiles, so the number physically in the box can differ. Before playing, confirm your set contains the 152 tiles required for standard American Mahjong: 36 each of Bams, Craks, and Dots; 16 Winds; 12 Dragons; 8 Flowers; and 8 Jokers.
3. Arrange the Players and Equipment
The four players sit around the table, one on each side. Each player places their rack in front of them, facing the center. The four sides of the table are associated with the four winds — East, South, West, and North — and the dealer is called East.
- EastDealer — 14 starting tiles
- SouthPlayer — 13 starting tiles
- WestPlayer — 13 starting tiles
- NorthPlayer — 13 starting tiles
Seating and dealer-selection customs can vary between groups. Some tables roll dice to assign seats and choose East; others simply take turns. There is no single universal seating procedure, so follow the convention your group uses. What matters for play is that all four players agree on who is East before the walls are built.
4. Mix the Tiles
Before building the walls, all 152 tiles are placed face down in the center of the table and mixed thoroughly. Players use their hands to shuffle the tiles so that no one can know which tile is which.
Beginner Tip
Keep all tiles face down while mixing. The whole point of this step is to randomize the set so that no player has information about which tiles are where.
5. Build the Four Walls
Once the tiles are mixed, each player builds a wall in front of their rack. A wall is a long row of tiles stacked two high. For a 152-tile set, each of the 4 walls is built from 38 tiles arranged as 19 stacks of two.

The four walls are pushed together to form a square in the center of the table. This square of tiles is what players will draw from during the game. The dimensions here —19 stacks per wall, two tiles per stack, 4 walls — are specific to American Mahjong's 152-tile set and differ from the wall sizes used in some other Mahjong variants.
6. Determine the Dealer (East)
East is the dealer and takes the first turn. How East is chosen varies by table convention. A common method is for one player to roll the dice and count around the table to select who deals; the dealer may then roll again to determine where the wall is broken. Other groups simply rotate the deal or assign East by agreement.
Because dealer-selection customs differ, treat any specific procedure as a table convention rather than a universal rule. The essential point is that East is the dealer, receives one extra tile, and takes the first turn after the Charleston.
7. Break the Wall and Deal the Tiles
This is the most important setup step to get right. After East is chosen, the dice are used to determine exactly where the wall is broken. East then begins dealing tiles from that break point, taking tiles in groups (typically stacks of two) and distributing them around the table.
The dealing proceeds around the table until each non-dealer has 13 tiles and East has 14 tiles. East's extra tile is what allows East to make the first discard and begin play.
East (Dealer)
14 tiles
South, West, North
13 tiles each
In total, 53 tiles are dealt to the four players; the remaining tiles stay in the walls to be drawn from during the game. Once the racks are dealt, players stand their tiles upright on their racks, concealing them from opponents.
Beginner Tip
The dealing step is separate from the Charleston. Dealing establishes each player's starting rack; the Charleston is the tile-passing phase that happens after the deal is complete.
8. Organize Your Starting Rack
Once you have your tiles, arrange them on your rack in a way that helps you spot possibilities. Many beginners group tiles by suit and number so that pairs, runs, and concentrations become visible at a glance.
- Place matching pairs together.
- Group tiles of the same suit (Bams, Craks, or Dots) next to one another.
- Line up consecutive numbers to spot potential runs.
- Set Winds, Dragons, and Flowers in their own section.
- Keep Jokers where you can see them — they're flexible and valuable.
Organizing your rack helps you compare your tiles against possible hands on the current NMJL card. A consecutive numerical run like 3-4-5-6 of one suit is a useful concentration, but it is not automatically a pung or kong — those require identical tiles. For a full framework on choosing a hand, see our hand-selection guide.
9. Get Ready for the Charleston
After the deal, the next phase is the Charleston — the series of tile passes that opens every American Mahjong hand. Before it begins, make sure each player has the current NMJL card available, since the Charleston is where you start shaping your hand toward a valid card pattern.
We cover the full passing sequence — Right, Across, Left; the optional second Charleston; blind passes; and the courtesy pass — in our Charleston rules guide. The key point for setup is simply that the Charleston happens after dealing and before ordinary drawing and discarding.
- 1Mix tiles face down
- 2Build four walls
- 3Roll dice & break wall
- 4Deal tiles (East 14, others 13)
- 5Organize your rack
- 6Begin the Charleston
10. How the First Turn Begins
Once the Charleston is complete, normal play begins. East takes the first turn. Because East was dealt 14 tiles — one more than everyone else — East starts by discarding one tile, which brings the rack to 13 and gives the first discard for other players to consider calling.
From there, play proceeds counter-clockwise around the table: each player in turn draws one tile from the wall and discards one tile. Don't confuse the Charleston with ordinary play — the Charleston is a one-time opening exchange, while drawing and discarding is the repeating rhythm of the game itself.
11. Common Setup Mistakes
Using an incomplete tile set
Always count your tiles before building the walls. A set missing even one tile can break the game.
Building walls with incorrect counts
Each wall is 19 stacks of two (38 tiles). Miscounting leads to uneven walls and a bad deal.
Giving every player 13 tiles
East must receive 14 tiles. If everyone gets 13, East can't make the first discard.
Forgetting the current NMJL card
Without the annual card, no one knows which hands are valid. Keep a current card at the table.
Confusing East with the other players
East is the dealer, takes the first turn, and starts with an extra tile. Don't lose track of who is East.
Exposing tiles accidentally
Keep tiles face down while mixing and face your rack toward yourself during the deal.
Starting ordinary play before the Charleston
The Charleston comes after the deal and before the first draw-and-discard turn.
Applying setup rules from a different variant
American Mahjong walls and dealing differ from Chinese or Riichi Mahjong. Use the 152-tile American standard.
