About Speedrun Minesweeper
Speedrun Minesweeper is the same deduction puzzle that has kept people busy for decades, rebuilt here as a fast, self-contained web game you can start in one click.
Speedrunning rewards muscle memory: recognising a pattern instantly is worth more than clicking fast. You clear the board by revealing every square that does not contain a mine. Numbers do the work for you — each one counts the mines in the eight cells immediately surrounding it.
Controls are deliberately small in number: left-click to reveal, right-click to flag, or use the on-screen mode toggle if you are playing on a touchscreen. The mine counter and timer update live as you play.
Nobody enjoys losing on move one, so the board is not built until you click. The generator then places all 40 mines away from your opening square and the ring around it, guaranteeing a usable cascade to start from. The build is intentionally light. Server-rendered HTML paints instantly, the game logic is a few kilobytes of client-side state, and every sound is generated at runtime by an audio oscillator instead of streamed from a server.
There is no score to chase but your own time, which is exactly why the game has outlived the hardware it was written for. Whether you are here for a quick distraction or a serious attempt at a personal best, the board is ready the moment the page finishes loading, and it costs nothing to try again.
