Dr. FreeCell

Dr. FreeCell is a simple addictive solitaire-based card game.

FreeCell is a solitaire-based card game played with a 52-card standard deck. It is fundamentally different from most solitaire games in that very few hands are unsolvable. Although software implementations vary, most versions label the hands with a number (derived from the random number seed used to generate the hand).
