A faithful trip back to Minesweeper, the way it looked on a Windows 3.11 desktop. Each number tells you how many of the eight surrounding squares hide a mine; from that alone you can reason out where the mines are. Left‑click (or tap) to uncover a square, mark the ones you've deduced with a flag, and clear every safe square to win. Your very first click is always safe.
Click an uncovered number whose mines you've already flagged to chord — it opens all the remaining neighbours at once. Beginner, Intermediate and Expert each keep your best time on this device; or set up a custom field of your own.
Left-click / tap uncovers a square; right-click, long-press, or Flag mode cycles flag → question → clear. Middle-click or clicking a satisfied number chords. Keyboard: arrows or WASD move, Space uncovers, F flags, R new game. A from-scratch recreation of the classic Minesweeper experience.
