Minesweeper

Minesweeper is a single-player logic puzzle that has been a staple of personal computing since the early 1990s. The goal is straightforward: uncover every safe cell on a grid without detonating a hidden mine. Each revealed cell either shows a number telling you how many of its eight neighbours contain mines, or it is blank — meaning no adjacent mines — which triggers an automatic flood-fill that opens all connected blank cells at once.

This version runs entirely in your browser with no downloads, no accounts, and no ads between games. Choose from three classic difficulties — Easy (9×9 grid, 10 mines), Medium (16×16 grid, 40 mines), or Hard (16×30 grid, 99 mines). Your first click is always safe because mines are placed after you make it. A live mine counter shows remaining unflagged mines, and a timer tracks how quickly you clear the board.
