Object To move all the cards to the foundations. Layout and play This variation of Forty Thieves is played in the same way as the parent game but with a Joker added to the deck. Foundations (8 piles: complete these piles to win the game) Build up in suit from Ace to King (for example, a 2 can be played only on an A ). Tableau (10 columns of 4 cards each) Build down in suit (for example, a 10 can be played only on a J ). The top card of each column is available for play to another tableau column or to the foundations. Only one card at a time can be moved. Spaces may be filled with any available card on the Joker . Whenever the Joker becomes available, it may be played to a foundation as a "wild" card. Additional cards in correct sequence are then built on the Joker. When the natural card (as shown in the label above the foundation) becomes available, it replaces the Joker, which is placed on top of its foundation and then may be built to another foundation pile. If no foundation has been started at the time the Joker first becomes available, it must remain in position until an Ace appears. Stock Turn up one card at a time from the stock to the waste by clicking. There is no redeal. Waste (1 pile) The top card is available for play to the foundations or to the tableau.
