Forty Thieves Solitaire | Master the Double-Deck Challenge

How to Play

Using two decks (104 cards), 40 cards are dealt face-up into 10 columns of 4 cards each. These are the "forty thieves."

Cards in the tableau must be built down in the same suit (e.g., a 9 of Hearts can only be placed on a 10 of Hearts).

Only the top card of each column is available for play. You cannot move sequences—every card must be moved individually.

The goal is to build 8 foundation piles from Ace to King by suit. The stock pile can be used, but only one card at a time.

An empty column is essential for maneuvering. Any single card can be placed there. Focus on clearing a column as early as possible.

You only get one pass through the stock pile. Don't waste cards on the tableau if they can go straight to the foundations.

With 104 cards, it's easy to bury Aces. Scan the thieves to see which Aces are near the top and prioritize uncovering them.
