How to play
Find 10 mines on a 9ร9 board. Each number counts the mines in the eight neighbouring cells. Reveal all 71 safe cells to win. The first reveal and its neighbours are safe; the timer starts with that first reveal.
Left-click to reveal and right-click to flag. On a phone, choose Reveal or Flag before tapping a cell. You have 10 flags; flag a marked cell again to remove its flag.
Arrow keys select a cell. Enter or Space applies the selected mode; F toggles a flag. P or Escape pauses and resumes while the board has focus. Clicking outside the game or switching windows pauses automatically.
