The short answer: In a 144-tile game the wall holds 136 tiles — four sides of 17 stacks, two tiles per stack — because the 8 flower tiles stay outside. American mahjong builds a 152-tile wall, 19 stacks per side. Each player builds one side.
The wall is the square of face-down tiles in the middle of the table. Every player builds one side, and the whole game is dealt out of it. The math is simple once you know what goes in: flowers never make it into the wall, and that changes the count.
How many tiles are in the full wall?
- 144-tile game: 136 in the wall — 17 stacks of 2 per side, 34 tiles per side.
- 136-tile game (no flowers): all 136 go in, still 17 stacks per side.
- American 152: jokers included, 19 stacks per side, 38 tiles per side.
How do you build the wall?
- Shuffle all the tiles face down on the table.
- Build a two-story row in front of you: 17 stacks of 2 tiles (19 in American).
- Push the four rows together into a square.
- Break the wall at the point the dice pick, and deal from there. Flowers drawn mid-game are replaced from the wall right away.

Related Questions
Why do flower tiles stay out of the wall?
They’re bonus tiles that never build a hand. Keeping them outside keeps the wall even, so every player draws the same number of tiles.
What happens if the wall runs out?
Usually a winner appears first. In several variants, a game with no winner is a draw and the next round simply starts.
How many tiles does each player start with?
Thirteen tiles each, with the dealer taking 14. Any flowers drawn during the deal are replaced immediately.
Does every mahjong game use a wall?
No — the wall belongs to the four-player game. Matching games like Turtle Mahjong lay tiles out differently, so there’s no wall at all.
