Forty Thieves Solitaire
The Forty Thieves is a two-decks patience. The game is begun by dealing 40 cards to the tableau arranged as 10 stacks of four cards each. Eight foundations are above the tableau. The remaining cards form the stock. The waste pile is beside the stock.
The object of the game is to build eight foundation piles up in suit running from Ace to King.
You can build tableau columns down in suit. Only the top card of a pile is available to play. In Figure, you can move A and 2 to the foundations, and place 7 on 8.
Empty spaces in the tableau can be filled with any card. The stock cannot be reused.
Try to create an empty space as soon as possible.
