· A secret signal exists that indicates whether a square is safe or mined. This tiny warning pixel sits in the upper left-hand corner of the screen and lights up white only when your cursor is over an unmined square. To turn it on, type “xyzzy”, then press ENTER, then SHIFT. The single pixel is hard to see unless you minimize everything but Minesweeper and use a dark, solid-colored Windows desktop.
