Infomation: Sly Fox Solitaire is played with 2 decks of cards. First, 4 A's and 4 K's are dealt as the start of 8 foundation piles.
The trick of this game is to manage the stacking order of the cards in the tableau piles. Put cards that can only be used late in the game at the bottom of the stacks. If two tableau piles have the same card, then the two piles should be stacked in different orders otherwise the game cannot be won.
