Cruel Solitaire is an old solitaire card game who's popularity has waned in the past decade or so. At one point a version of it was distributed with the Microsoft fun pack. It's a pile based game like La Belle Lucie or Shamrocks, that has an interesting 'Shift' feature. This picks up all the cards that haven't been moved to the suit piles and shifts them to the left into piles of 4 cards again. This movement is predicatable and allows you to use it to shift around the cards that you need so you can move them into the suit piles. You can use this as many times as you want in a given game.
