OSX FreeCell is a very addictive solitaire card game. It differs from other solitaire card games in that winning other solitaire card games depends mostly on luck, with FreeCell, winning depends mostly on SKILL. Just about every FreeCell game is potentially winnable. It just may take some studying and thinking to figure out how.
