Cruel Solitaire, is a popular solitaire card game where the aces are pulled out of the deck at the beginning of the game and moved to the foundations. The remaining cards are dealt into piles of four cards each. The player can move the top card in each of these piles, and use them to build down the other piles by suit, or to build up the foundations by suit. At any time the player can shift all the cards in the piles back into piles of 4 cards each without reshuffeling them. The player can do this as many times as he likes.
