Sol Free

This is like a regular Solitaire.
The Sol Free has six different games: Baker's Game, Baker's Game Easy, Demon, Klondike Deal 1, Klondike Deal 3 and Spiderette. It won two awards last year: iTunes Best of 2008 (Top Free Games) and 2008 Best App Ever Awards (Nominee and Best Free Game).
It is easy to play with in-game rules, unlimited undo, tap card movement and more.
