Frequently asked questions
Is Minesweeper Lab free to play?
Yes. Every mode is completely free, with no login, no ads and no downloads. Open the page and start playing instantly in your browser.
Can I play Minesweeper on my phone?
Yes. The board is mobile-first: tap to reveal a square, long-press to place a flag, or switch on Flag mode for one-tap flagging. Infinite mode lets you drag to pan the board.
What is the difference between Classic and Infinite Minesweeper?
Classic Minesweeper uses a fixed grid (9×9, 16×16 or larger) with a set number of mines and a clear win condition. Infinite Minesweeper has no edges — the board is generated endlessly from a seed, and your goal is to clear as many squares as possible.
Is the first click always safe?
Yes. In every mode your first click is guaranteed not to be a mine, so you always get a usable opening.
