Solitaire card games are much alike. Different terms are used to indicate the same game: freecell, solitaire, solitaire freecell or even patience. The latter is a game for a single player as well, but it has different rules. The free cell game acquired fame since it became a standard feature in the windows package.
The 52 card deck is shuffled and divided in 8 stacks. The aim of the game is to pile the cards up in sequence on the 4 stacks. The cards on a stack must be of the same color, starting from Ace and counting up through two until the stack is completed by the king. The four open spots can be used to store cards temporarily. The amount of cards you are allowed to move per turn depends, however, upon the number of free cells you have left. Have fun!
