How to play Forty Thieves

How Forty Thieves starts: stock, waste, eight foundations, and ten columns of four, all face up.

Forty Thieves uses two decks, 104 cards. Forty are dealt face up in ten columns of four; the other 64 are the stock. Build all eight foundations from Ace to King, two for each suit, to win.

Undo has no limit, and it can take back a card turned from the stock too.

Tips

Keyboard

Arrow keys move between cards and places. Enter or Space selects a card and places it. D turns a card from the stock, H shows a hint, Escape cancels a selection, and Ctrl+Z undoes a move.

Questions

How many cards can I move at once?

One at a time, by the rules. When you have empty columns, the game moves a run in one suit for you, one card at a time through the empty columns: 2 cards with one empty column, 4 with two, and so on.

Why is Forty Thieves so hard?

Columns build only in one suit, and the stock goes through once. When we tested 30 random deals with a computer solver that could see every card, it found a win in only 3. Unlimited undo helps you try another way.

Can every daily deal be won?

Yes. The solver checks each daily deal before we publish it. Ordinary deals are random, and most of those can't be won.
