How to Play Mahjong Solitaire: The Complete One-Player Guide

Mahjong Solitaire is the world's most-played one-player Mahjong: no opponents, no mandatory clock and the very same tiles as the traditional Chinese game. Here is how it works and how to win more often.

What is Mahjong Solitaire

Mahjong Solitaire (also called Mahjong Titans, Shanghai, or simply "one-player Mahjong") is a tile-matching puzzle, not a game played against other people. You face a board built in layers and must clear every tile, two at a time, until nothing remains. There is no opponent, no turns and no mandatory scoring: the only "score" is an empty board.

It was born in the 1980s, when developers took the 144 tiles of classic Mahjong and rearranged them into a stacked pyramid to make a solo logic challenge. The result swept through computers, then phones, and today it is the entry point to Mahjong for millions of people — including here on our site, where you can play free Mahjong Solitaire any time.

What the board looks like (the "tortoise")

When you open a round, you do not see tiles scattered on a flat plane: you see a structure of several overlapping layers, like a little fortress of tiles. Each tile may sit on top of, in the middle of, or beneath other tiles. That stacking is exactly what creates the challenge.

The free-tile rule (the one that decides everything)

The same release rule applies in all Mahjong — classic or solitaire — but in Solitaire it is the heart of the game:

That is why the edge tiles and the tops of the stacks are almost always the first available moves. As you clear pairs, the lower layers are released — and the shape of the board changes with every move.

Why the layout matters

The layout is the design of the layers. It decides how many tiles there are, where they stack, and therefore the difficulty. The very same set of 144 tiles can become an easy or a near-impossible challenge depending on how it is arranged.

How to play Mahjong Solitaire step by step

1. Study the whole board. Before the first click, scan the layers and find where tiles pile up the most.
2. Spot the free tiles. Go for the edges and the tops of the towers — that is where the possible moves almost always are.
3. Look for a free pair. Two tiles with the same symbol, both of them free.
4. Click one, then the other. If the match is valid, both vanish and release whatever was beneath or beside them.
5. Reassess after every move. The board reshapes with each removal; go back to step 2.
6. Keep going until you clear it — or use Shuffle. No tiles left means you win. Stuck? The Shuffle button re-stacks the remaining tiles.

If you are starting from scratch, read our beginner's guide to Mahjong first — it explains the tiles and the goal from zero. Solitaire uses exactly the same tiles; what changes is that here you play alone.

The most common layouts

• Turtle: the classic of classics, with a tall "shell" in the centre and thin layers at the edges. Balanced and perfect for learning.
• Pyramid: perfectly triangular layers, more predictable and friendlier for practice.
• Carpet / Net: tiles almost all on one level, with few layers — easier to read, but it demands planning the sides.
• Fortress and Sponge: chaotic, tall designs for players who already master the basics and want a real challenge.

Strategies to clear the board

• Attack the tall stacks first. Stacked tiles lock everything underneath; dismantling the towers early opens up the game.
• Free long rows from the ends. Only the two ends are free, so clearing from the sides is what unlocks the middle.
• When all four copies are visible, remove the two most trapped. That keeps the easy pair in reserve for the end.
• Don't spend a pair just because you see it. If both tiles are loose, they can wait — use the move to unlock another area instead.
• Use Hint and Shuffle with a clear head. Hint gets you out of a pinch; Shuffle rescues a stuck board. But lean on them too much and you stop seeing the pairs yourself.

Solitaire vs Classic: which to play

The "real" (classic) Mahjong is a four-player game with turns, discards and scoring. Solitaire inherits the tiles and the free-tile rule but swaps the opponent for a built board. To relax, train your eye and play anywhere, Solitaire wins. For the full social and strategic experience, classic is the natural destination — and the two versions complement each other.

Your next steps

To sum up: identical tiles form pairs, only free tiles leave, and the board must end up empty. The rest is practice and board reading. Start with a small Turtle layout, move up to the Pyramid, and once you feel comfortable try the other modes on the site. And of course, open a round of free Mahjong Solitaire and put this guide into practice right now.
