Freecell Duplex

Game rules:

Freecell Duplex is a single player card game that uses the basic concept of Freecell Solitaire, but adds a unique twist: two decks. The object of the game is to move all the cards into eight foundation piles by suit from Ace to King, in 20 minutes.

To start a game of Freecell Duplex, set up a layout that includes eight Free Cells and twelve tableau piles. Each of these piles contains face-up cards. Eight foundation piles are empty. Maneuvers in the game involve moving cards around the board, to Free Cells, or to foundations. Any card can be moved to an empty tableau pile or to an Free Cell. During the game, tableau piles are built in descending order of suit.
