|A Patience game|
Duchess (also Dutchess) is a solitaire card game which uses a deck of 52 playing cards. It has all four typical features, a tableau, a reserve, a stock and a waste pile, and is quite easy to win.
First, four fans of three cards are set up; they form the reserve. Then a space is left for the four foundations, then four cards are placed in a row; they form the bases for the tableau columns.
To start the game, the player will choose among the top cards of the reserve fans which will start the first foundation pile. Once he/she makes that decision and picks a card, the three other cards with the same rank, whenever they become available, will start the other three foundations.
The top cards of the reserve fans and the top cards of the columns in the tableau are available for play onto the foundations or on the tableau. The foundations are built up by suit and ranking is continuous as Aces are placed over Kings. The cards on the tableau are built down in alternating colors. Ranking is also continuous in the tableau as Kings can be placed over Aces. One card can be moved at a time, but sequences can also be moved as one unit. No cards can be built on the reserve.
Spaces that occur on the tableau are filled with any top card in the reserve. If the entire reserve is exhausted however, it is not replenished; spaces that occur after this point have to be filled with cards from the waste pile or, if a wastepile has not been made yet, the stock.
The stock is dealt one card at a time to the wastepile, the top card of which is available for play. There is one redeal allowed. To prepare for the redeal, the remaining cards in the wastepile are collected and turned face down to become the new stock.
The game is won when all cards are built onto the foundations.
