Play Minesweeper Online — Free, and No Guessing
Classic Minesweeper with one big difference: every board here is guaranteed solvable by pure logic. A solver checks each board before you see it and throws away any that would force a blind guess — so there is always a safe next move to find. And when you are stuck, a built-in coach shows you a square that is provably safe and explains, in plain English, exactly why. Play right now, free, no download and no account.
How to play Minesweeper
- Tap any square to start. Your first tap is always safe and opens a whole region.
- Each revealed number tells you how many of that square's eight neighbours are mines. A blank has zero, so its neighbours open for free.
- Use the numbers to deduce which covered squares are mines and which are safe.
- Flag a mine by long-pressing it (or with the flag toggle, or right-click on desktop). Flags are just notes — they never end the game.
- Reveal every safe square to win. Reveal a mine and it's over.
What makes these boards "no-guess"
In ordinary Minesweeper you can play perfectly and still lose to a 50/50 guess at the end. Here that never happens. Every board is generated, then replayed through a logic solver; if the solver can't finish it without guessing, the board is discarded and a new one is dealt. The result is a pure puzzle: if you lose, a safe move existed — and the post-game review will show you which one.
The coach that explains itself
Most "helper" sweepers just flash a symbol at you. Ours talks. Tap 💡 Coach and it finds one square that is provably safe, rings it in gold, and tells you in words which nearby number proves it — for example, "R4C6 is safe: the 1 at R3C6 already touches a flagged mine, so its other neighbours are clear." You learn the pattern instead of just being handed the answer.
Board sizes & scoring
- Easy — 9 × 9 with 10 mines. A quick, gentle solve.
- Medium — 13 × 13 with 28 mines. The everyday puzzle.
- Hard — 16 × 16 with 45 mines. For a real logic workout.
- There are no points — just your time. Your best time for each size is saved on your own device, so you can chase a personal record.
Strategy tips
- Start from the numbers touching the fewest covered squares — a 1 next to a single covered square marks a certain mine.
- When a number already touches as many flags as its value, its other neighbours are all safe — tap the number to open them at once (chording).
- Learn the 1-2-1 and 1-1 edge patterns; the coach will name them for you when they come up.
- No board needs a guess — if you feel like flipping a coin, there is a deduction you're missing. Ask the coach.
Frequently asked questions
- Is this Minesweeper game free?
- Yes — completely free in your browser, no download and no account. Your best time for each board size is saved on your own device.
- What does "no-guess" mean?
- Every board is checked by a solver before you play it. If finishing it would ever require a blind guess, that board is thrown away and a new one is dealt — so a logical next move always exists.
- How does the coach work?
- Tap Coach and it finds a square that is provably safe, rings it, and explains in plain language which nearby number proves it — so you learn the pattern, not just the answer.
- How do I flag a mine on a phone?
- Long-press a square, or turn on the flag toggle at the bottom-left and tap. On desktop you can also right-click. Flags are only notes and never end the game.
