About this game
Mahjong solitaire — often called Shanghai — is a puzzle where you clear a stack of mahjong tiles by removing identical pairs until the board is empty. You need no knowledge of mahjong hands or scoring: the whole game is spotting matching faces and knowing which tiles you are allowed to take.
A tile can be taken only if two things are true: nothing is stacked on top of it, and either its left or its right neighbour is gone. Selectable tiles are drawn bright and blocked tiles are dimmed, so you can read the board at a glance instead of working the rule out in your head.
The biggest complaint about this genre is being dealt a board that simply cannot be finished. That is ruled out here by construction: the board is filled by simulating the removal in reverse, so every deal has at least one complete solution. Over 8,000 generated deals were replayed during development to confirm each one can be cleared.
There are three sizes: Easy is 48 tiles across 2 layers, Normal is 68 tiles across 3, and Hard is 100 tiles across 4. More layers means more tiles hidden underneath and more need to plan ahead. Start on Easy to get used to scanning the board, then work upward.
Tips & strategy
- Work from the top down. Removing a low tile does not free the tiles above it — it only opens sides. Clearing the upper layers first widens your options fastest
- When all four copies of a face are visible, think about which two to take. Removing the easy pair can bury the remaining two
- Tiles on the outer columns usually have a free edge and stay available. Tiles buried in the middle are worth digging out early
- Combos build when you match again within five seconds. Spot two or three pairs first, then clear them back to back
- A hint costs 500 points and a shuffle costs 1000. Reshuffling before you are completely stuck is sometimes cheaper than grinding into a dead end
FAQ
Q. Do I need to know mahjong rules?
A. No. Only the tile faces matter — there are no hands, no scoring and no calls. If you can spot two matching pictures, you can play.
Q. Can I be dealt an unsolvable board?
A. No. The board is built by simulating the removal in reverse, so every deal has a complete solution. Shuffling rebuilds the remaining tiles the same way, so the position stays solvable.
Q. How do I know which tiles I can take?
A. A tile is available when nothing is on top of it and either its left or right neighbour is gone. Available tiles are bright and blocked ones are dimmed — look for a matching pair among the bright tiles.
Q. What happens if I run out of moves?
A. Use Shuffle to re-deal the remaining tiles. Shuffles are limited; if you run out of moves with none left, the game ends. A shuffled board is still guaranteed solvable.
Q. How is the score calculated?
A. 300 points per pair, plus a combo bonus for consecutive matches. Clearing the board adds a bonus that grows with difficulty and shrinks with time. A hint costs 500 and a shuffle costs 1000. Only a completed board can be submitted to the leaderboard.
