About Edge Strategy
Welcome to edge strategy — a complete 16x16 Minesweeper board with 40 mines, first-click safety and synthesized retro sound, running natively in your browser tab.
Edge squares have five neighbours instead of eight, which halves the guesswork. The board speaks in numbers. A three means three of the eight touching squares are mined; a satisfied number means every remaining neighbour is provably safe to open.
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.
First-click safety is built in. Mines are placed only after your opening dig and never inside the 3x3 area around it, which means every game starts with real information instead of a coin flip. Technically the whole thing is a small React application styled with Tailwind CSS. The page is server-rendered, so search engines and slow connections both receive readable HTML immediately, and the sound effects are synthesized live with the Web Audio API rather than downloaded as files.
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.
Highlights
