Minesweeper

Minesweeper online is the classic logic game in your browser: 10 mines hide on a 9×9 board and you have to open all 71 safe tiles. A number shows how many mines touch that tile, and empty areas open in one go. Your first click is always safe — there is no mine on it or next to it.

Flags mark the mines, the timer and mine counter track the round, and your best time is saved as a record. When you get stuck, a hint opens a safe tile or flags a mine, and a bad move can be undone.

Tips:
1. Start at the corners and edges — tiles there have fewer neighbours.
2. If a 1 has only one closed neighbour left, that is the mine.
3. Only flag a tile when you are sure.
4. Against a wall, the 1-2-1 pattern almost always solves without guessing.
5. Logic first, speed later.

FAQ:
— How do I play minesweeper? Open tiles and use the numbers to work out where the mines are.
— Is it free? Yes, with no sign-up or download.
— How do I flag on a phone? Long-tap a tile.

How to play:
Open all 71 safe tiles on the 9×9 board without hitting any of the 10 mines.
1. Your first click is safe: no mine on that tile or next to it.
2. A number shows how many mines are in the eight surrounding tiles. A tile with no mines around opens together with its empty neighbours.
3. Flag a tile when you are sure it hides a mine.
4. Click an open number to open its closed neighbours when exactly that many flags surround it.
5. Hit a mine and the round is over. Undo takes back a move, and Hint opens a safe tile or flags a mine.

Desktop: left click opens, right click flags, left click on a number opens its neighbours.
Phone: short tap opens, long tap flags; the Reveal / Flag toggle switches what a normal tap does.
