Forty Thieves Solitaire

Two decks. Ten tableau columns. Cards build down by suit only, and groups cannot be moved as a unit. Forty Thieves is one of the oldest and most demanding classic solitaires — strong players win around 10% of hands. The name is said to come from the forty face-up cards dealt at the start ("the forty thieves"), each waiting to be stolen back into the foundations.

How to Play Forty Thieves

3 Strategy Tips for Forty Thieves

  1. Empty a column early. An empty column is one of your only real maneuvering tools in this game. Aim to clear a column on the first pass.
  2. Use the waste sparingly. Once a card lands in the waste, it's only accessible when it cycles to the top. Plan tableau moves before flipping more stock.
  3. Hold low cards. Aces and 2s are anchors. Send them up only when the foundation is genuinely ready to keep going.
