These are really working.
1. Minesweeper
Start it (of course)
the write xyzzy and press shift+enter at the same time
then adjust your screen so that EVERY pixel is watchable, move your cursor over a block in the game and watch the upper left pixel of the whole screen. White= clear Black= Mine
2. Freecell
Press ctrl+shift+F10 and then just read the lines there
