How to play
- Left-click a square to open it. The number says how many mines touch it.
- Right-click to plant a flag — on a touchscreen, press and hold instead.
- Click an open number that already has the right count of flags around it to open every other neighbour at once.
- Your first click is always safe, so no game is lost on move one.
- Score is your time, so lower is better. Each board size keeps its own best.
