Minesweeper

The board is filled with hidden mines. Your goal is to reveal every cell that isn't a mine without blowing anything up.

Left-click a cell to reveal it. If it's a mine — game over. If it's safe, it shows a number (or blank if no mines are adjacent).

The number on a revealed cell tells you exactly how many mines are touching that cell (including diagonals). Use these numbers to work out where mines must be.

Right-click (or long-press on mobile/iPad) a cell to plant a 🚩 flag. This marks it as a suspected mine so you don't accidentally click it. Right-click again to remove the flag.

Worried about fat-fingering a mine on a touchscreen? Turn on 🚩 Flag Mode in the controls bar — while it's on, a normal tap plants or removes a flag instead of revealing the cell, so you can mark up the whole board safely before switching it back off to dig.

A blank cell (no number) means no adjacent mines — clicking it automatically reveals all neighbouring safe cells, cascading outward.

You win when all non-mine cells are revealed. The mine counter shows how many mines remain unflagged.
