Mahjong Solitaire
Match free pairs of tiles and clear the whole board.
How to play
- Find two identical tiles that are both free, and click them to take them off the board.
- A tile is free when nothing is stacked on top of it and its left or right edge is open — blocked tiles look slightly dimmed.
- Any flower matches any other flower, and any season matches any other season. Every other tile needs its exact twin.
- Hint highlights a pair, Undo takes a move back, and Shuffle re-deals the remaining tiles if you run out of matches.
What it trains
- Visual search practice — scanning a crowded board for the pair that matters
- Rewards thinking one step ahead: which tiles does this match set free?
- Calm by default: no timer, no ads, no account, and no way to lose
Play mahjong solitaire free online with no time limit: match two identical tiles that are free to lift, and keep clearing until the board is empty. The classic 144-tile turtle, or a smaller board that fits a phone screen. Every board is dealt so it can be finished — and Shuffle re-deals the rest into another solvable board if you get stuck, so there are no dead ends. Nothing to download, no ads, no account, and no game over; the timer is off unless you turn it on. Large-tile full-screen mode, mouse or keyboard, and your board is saved if you close the tab.
