Forty Thieves Solitaire

Objective

Move all 104 cards (two decks) onto eight foundations, each built up from Ace to King in a single suit.

The Layout

• Ten tableau piles of four face-up cards each
• Eight foundations across the top — any Ace seeds an empty slot
• Stock at top right; draws one card at a time. No recycle — you only get one pass.

Moving Cards

• Only the top card of a tableau pile can be moved
• Tableau builds descending in the same suit
• Any single card can fill an empty tableau column
• Send Aces and matching ranks to the foundations whenever possible

Tips & Strategy

• Forty Thieves is famously hard — play conservatively
• Hold the stock as long as you can; once it is empty there is no recovery
• Empty columns are powerful temporary storage — guard them
• Use Undo freely to explore branches
