This is a copy of the classic game Minesweepers. The object is to locate all the mines in the field. There are 10 mines. Click on a square to uncover it. Press <b> to make your clicks flag the square (mark it as a mine). Press <v> to make it a "maybe" flag. Press <c> to go back to normal uncover mode. A small flag will follow your mouse if you're in flag mode. Don't click on the mines!
