What Is Mahjong Solitaire (Shanghai)?
Mahjong Solitaire, often called Shanghai, became a computer puzzle in 1981 when Brodie Lockard created a tile-matching game on the PLATO system. Activision later published Shanghai in 1986, helping the format reach home computers. The goal is simple: remove matching open tile pairs until the layout is empty. The challenge comes from blocked tiles, stacked layers, and the order in which you free pairs. Start matching tiles and clear the Shanghai layout online.
How to Play Mahjong Solitaire (Shanghai)
- Find two identical tiles that are both free.
- A tile is free when no tile covers it and at least one long side, left or right, is open.
- Click or tap the first tile, then choose its matching partner.
- Remove pairs to expose lower and inner tiles.
- Keep matching until every tile is gone.
- Restart if no legal pairs remain.
Basic Rules
- Most layouts use a 144-tile mahjong set.
- Only free tiles can be selected.
- Matching tiles usually need identical faces.
- Flower tiles and season tiles may use group matching in some rule sets.
- You win by removing every tile from the layout.
- You lose or reshuffle when no legal free pair remains.
Strategy Tips for Beginners
- Remove pairs that unblock the most tiles. A pair on the edge may be less valuable than a pair covering the center.
- Balance both sides of the layout. Clearing only one side can leave the other side locked.
- Look under tall stacks first. Upper layers hide many future matches.
- Do not remove an easy pair if another copy of that tile blocks a deeper layer.
- Use memory. When you see a matching tile buried, remember which tile must be freed later.
Real Examples of Gameplay
Opening Pair
Two 3 Bamboo tiles sit free on opposite outer edges. Removing them opens two new side tiles and creates more pair options.
Center Stack
A Dragon pair sits on the top layer. Remove it early because top-layer tiles block several tiles underneath.
Bad Pair Choice
You remove two free East Wind tiles while a third East Wind blocks the center. Saving one free East Wind might help unlock that center tile later.

Frequently Asked Questions
Is Mahjong Solitaire the same as four-player mahjong?
No. Mahjong Solitaire uses mahjong tiles for a single-player matching puzzle. Four-player mahjong is a separate draw-and-discard game.
What makes a tile free?
A tile is free when no tile sits above it and either its left or right side is open.
Are all Mahjong Solitaire layouts solvable?
No. Some random deals can block all future matches, especially without a guaranteed-solvable shuffle.
Should I use hints?
Hints help when learning, but try scanning top layers and blocked center tiles first.
