About Math Minesweeper
Welcome to math minesweeper — a complete 16x16 Minesweeper board with 40 mines, first-click safety and synthesized retro sound, running natively in your browser tab.
Each number is a small equation: adjacent mines minus placed flags equals what is still hidden. 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.
Use the left mouse button to open squares and the right button to mark suspected mines. Touch users get a dedicated mode button instead of an awkward long press, which keeps flagging fast under time pressure.
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.
Reset as often as you like — every restart randomises a completely new layout, so no two boards are ever quite the same. 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.
