On a mahjong solitaire website the board appears fully built the moment you click a layout, so you never have to set it up yourself. But understanding how a layout is constructed makes you a better player, and it is essential if you ever want to play with a physical set. This guide walks through the tile set, how layouts are built, and the difference between online and physical setup. For the matching rules once the board is built, see our Mahjong Solitaire Rules guide.
What Is in the Box
A standard set has 144 tiles built from surprisingly few pieces. Here is the full inventory you would lay out on a table:
| Group | Contents | Tiles |
|---|---|---|
| Dots | Ranks 1–9, four copies of each | 36 |
| Bamboo | Ranks 1–9, four copies of each | 36 |
| Characters | Ranks 1–9, four copies of each | 36 |
| Winds | East, South, West, North — four copies each | 16 |
| Dragons | Red, Green, White — four copies each | 12 |
| Flowers | Four single tiles; any Flower matches any Flower | 4 |
| Seasons | Four single tiles; any Season matches any Season | 4 |
| Total | 144 |
Every layout on this site uses this same set—the one exception is Double Play, which stacks two full sets for 288 tiles and our longest measured game at 10 minutes. For what each tile looks like, see our Mahjong Tiles Meaning guide.
How a Layout Is Built
A layout is a shape built from the 144 tiles, stacked in one to five layers. The Turtle, for example, uses a flat base with a raised dome on top. The placement rules are simple: every tile sits either on the table or on top of other tiles, and the shape must be stable. What changes between layouts is geometry, not content—and geometry is difficulty. Our measured times show it directly: the flat Classic clears in 3 minutes, the domed Turtle in 4, and the long stacked rows of Great Wall take 8, all with the identical 144 tiles.
Online vs Physical Setup
- Online — the board appears instantly, shuffled randomly. Click and play. A fresh shuffle every visit, zero setup time.
- Physical — shuffle the 144 tiles face-down, then stack them into the shape by hand. Setup takes about five minutes once you know the shape, and the Turtle is the easiest layout to build.
A practical tip for physical builds: sort the set into the seven groups from the table above before you shuffle. It cuts cleanup time in half and teaches you the tile faces as a bonus.
Frequently Asked Questions
Do I need to set up the board myself online?
No. The site shuffles and deals the tiles into the layout automatically every time you open a game.
How long does physical setup take?
About five minutes once you know the shape. The Turtle is the easiest layout to build by hand.
