About Forty Thieves Solitaire
Forty Thieves — also called "Napoleon at St Helena" — is a two-deck patience game played with 104 cards. Forty cards are dealt face up into ten columns of four. Your job is to build eight foundations, each running up from Ace to King in a single suit. Send all 104 cards home to win.
How to play
You may move one card at a time. On the tableau, build down in the same suit — a 6♠ goes onto a 7♠. Send any Ace to a foundation, then build it up by suit to the King. The top card of the waste and the bottom card of each column are the cards you can move. An empty column can take any single card.
The stock
Tap the stock to turn cards to the waste, one at a time. The top of the waste is always in play — but there is no redeal: once the stock runs out, you finish with the cards on the table. That single pass is what makes Forty Thieves famously tough.
Is it hard?
Yes — Forty Thieves is one of the hardest popular solitaires, with a low natural win rate. That is exactly why undo here is unlimited: take any move back, explore a different line, and learn the deal. Clear one and your streak grows; your streak is saved on your device, waiting for your next session.
