Infomation: Trefoil Solitaire is a single player card game, where the four aces are removed from the deck and used as the start of the four foundations. The remaining 48 cards are dealt into 16 piles of 3 cards each. Only the top card in each of these piles may be moved. The piles may be built down by suit, and the foundations must be built up by suit. When a player gets stuck, he is allowed to shuffle and redeal all of the cards not currently in the foundations up to three times. When all the cards have been removed from a pile, that space can not be filled with any card. In Trefoil Solitaire, once a pile is gone, it is gone for good. To win, the player must move all 52 cards to the foundations.
