Have you ever played Mastermind? You have four holders for six crystals. Keep in mind that crystals (colors) can be repeated. You have 8 chances to deduce the correct order to place all four crystals. Once you've picked the four you want to try, four quadrants appear below your choices. The quadrants turn white if you have the correct crystal (color), black if it's the right crystal in the right place.

But the quadrants don't line up with the order of the crystals! This is definitely a hard puzzle game to play, but each game should be over quickly.
