Ok.. Everybody has already played Minesweeper, right?
It's been in Windows since 3.1 and i bet everybody has had a go at it.
It's a very basic game, and sometimes is based in luck. Well... Not anymore!
-After starting the game, type xyzzy and press Shift and Enter at the same time.
-Move the mouse over the playing area and keep your eye on the upper left corner of the Windows desktop.
-A white pixel will appear when the mouse pointer is over a safe square, and turn dark when the mouse is over a mine.
I think that's the weirdest cheats i've ever seen, still, it does work, and i'd love to talk to the man who had the idea of including this on the program!
