Forty Thieves Solitaire is a challenging, two-deck solitaire game where you move all cards from ten tableau piles (the “thieves”) to eight foundation piles, building up by suit from Ace to King. The tableau piles are built down by suit, and only the top card is available, making it difficult as you can only move single cards, not sequences, and only have one pass through the stock, demanding strategic use of empty tableau spots for reordering.
