It works on minesweeper as long as you don't have a vista wich has the pimped out shiny version of Minesweeper. You bring up the game and type in the xyzzy or what ever I said in the first post. I forget now lol. right after that hold the shift button till a white pixel shows up in the top left hand corner of screen. (Nice to have a dark background) When you move your mouse around the field it will stay white or turn black. If it turns black, it means that square is a bomb. If it stay white, then it means it safe to clear.
