Double Solitaire is a Solitaire game that is played by two people instead of one person playing against the computer. There are two stacks of 52-card decks. There are 28 cards in seven piles for each person, with the top card facing up. Once the game is set up, each player takes turns flipping over cards and playing their own game of Solitaire. Each player can move their cards around in a different formation when it is their turn.
