Minesweeper

How to play

Classic Minesweeper. 12×12 grid, 20 mines. The puzzles are designed so no guessing is needed (every move can be deduced).

Left-click any cell to reveal it. If it's a mine, you lose. If it's safe, you'll see a number: that's how many mines are in the 8 cells touching it (including diagonals). A blank cell means zero adjacent mines, so all its neighbors auto-reveal as well. Use the numbers to work out where the mines must be, then right-click (or long-press on mobile) to flag each one. Once a number has the right count of flags around it, left-click that number to "chord", instantly revealing all its remaining safe neighbors. Start with the green X; it's a guaranteed safe cell that opens a large area.

No timer, no scoring. This is just to learn.
