Minesweeper Online Free – Reveal, Flag, Clear
Minesweeper Online Free is the classic minefield: Easy 9×9 / 10 mines, Normal 16×16 / 40, Hard 16×30 / 99. Open safe cells, flag mines, and beat your local best time. Hit a mine and click or press R to restart instantly.
About this game
The first click is always safe and places the minefield afterward. Numbers show how many mines touch that cell; empty opens flood outward. Right-click (or Shift-click) toggles flags. Double-click a revealed number when its flags match the count to auto-clear the rest (chord). A timer starts on your first reveal; each difficulty stores a best time in this browser. Clearing all non-mine cells wins; revealing a mine loses—click the board to deal a fresh field.

Common use cases
- Play classic minesweeper when you want careful clicking, not twitch reflexes.
- Practice reading number patterns before committing flags.
Tips
- Double-click a revealed number when its flags match the count to auto-clear flagged neighbors (chord).
- Flag only when a mine is forced—guesses late in the board cost the round.
- Use NEW or R after a loss instead of refreshing the page.
FAQ
How do I win Minesweeper Online Free?
Reveal every cell that is not a mine. You do not need to flag all mines if the safe cells are all open.
What does a number on a cell mean?
It counts how many mines are among the eight neighboring cells.
What happens if I click a mine?
The round ends. Click the board, press R, or hit NEW for a fresh field on the same difficulty.
Is the first click safe?
Yes. Mines are placed after your first reveal so that opening cannot hit a mine immediately.
How does double-click chord work?
On an opened number cell, if the number of neighboring flags equals that number, double-click opens every remaining unflagged neighbor. Wrong flags can still hit a mine.
Is this minesweeper free in the browser?
Yes. No download or account is required.
