How to play

Left-click a covered square to reveal it.
Right-click (or long-press on touch) toggles a flag.
Left-click a revealed number whose flags already match it to clear the squares around it.
A number counts the mines in the eight neighbouring squares.
Your first click is always safe — it opens a region.
Reveal every square that is not a mine to win.
