Minesweeper is the classic logic puzzle: a nine-by-nine board hides ten mines, and each revealed square tells you how many mines touch it. From those numbers you deduce where the mines must be, flag them, and clear every safe square. This version adds first-click safety, so your opening move never hits a mine, plus a flag mode for marking suspects. It is distinct from snake, which is a reflex game; minesweeper rewards pure deduction, and one careful inference at a time clears the board. It runs entirely in your browser, so there is nothing to install and nothing to sign up for, and you can use it on a phone, tablet or desktop whenever the need comes up. Because it works on the spot, you can fit it into a busy day without changing your routine, and the result is ready in seconds rather than after a setup process.
Quick Answer: Click a square to reveal it. Numbers show adjacent mines. Use Flag Mode to mark suspected mines, and clear all safe squares to win. It is free, needs no sign-up, and works instantly in your browser on any device.

Best Practices and Tips
- A 1 next to a single hidden square means that square is a mine.
- A revealed number with all its mines already flagged means the rest are safe.
- Flag methodically; guessing early creates confusion later.
- Start from corners and edges, where fewer neighbours hide mines.
- When stuck, pick the square with the lowest mine probability.
- Try the tool with a real example from your own work first, since a concrete case shows its value faster than a test input.
- If a result looks unexpected, recheck your inputs before assuming the tool is wrong, since a single mistyped value changes most outputs.
Common Mistakes to Avoid
- Clicking randomly instead of reading the numbers.
- Forgetting to flag, then losing track of suspected mines.
- Revealing a square that a number already proves is a mine.
- Assuming a 50-50 guess is safe instead of checking other clues.
- Skipping the instructions and guessing how the tool works, then blaming the result when it does not match expectations.
Frequently Asked Questions
How do I win?
Reveal every square that does not hide a mine. Flagging mines helps you track them, but clearing safe squares is what wins.
What does a number mean?
It counts the mines in the eight surrounding squares, including diagonals.
Can the first click hit a mine?
No. Mines are placed after your first click, excluding that square, so the game never ends on move one.
How do I flag on mobile?
Use the Flag Mode button, then tap squares to place or remove flags. Tap Flag Mode again to return to revealing.
