Object of the game
The object of the game of Forty Thieves is to move all the cards from the tableau and discard pile to the foundations.
Forty cards are laid out in 10 tableau piles. There are four cards to each pile and they are placed face up and fanned out. The lingering cards stay in the deck. The eight foundation piles and one discard pile start out empty. Work on these as the game goes on. The top cards of the tableaus and the top card of the discard pile are deemed available.
Build the tableaus down according to suit. Any accessible card may be played to an empty tableau. Move only one card at a time. Multi-card moves are not allowed. (A multi-card move means to take a group of cards from a tableau and move it to the foundation.)
Foundation piles are built up according to suit (starting with the Ace and ending with the King).
Deal a new card any time from the deck to the discard pile. Do this if there are no more moves available from the tableau.
