Sol Free Solitaire is a classy solitaire app that delivers three games (Klondike Deal 3, Demon, and Baker’s Game), easy-to-read graphics, and enough documentation to make for a fine introduction to the world’s loneliest card game. Taps move your cards, the Auto command gets cards into your foundation piles quickly, and tapping Undo does what you'd expect to your last action. Sol Free Solitaire is great for the price, but we wouldn't mind having options to mix up the game's appearance. We got several low memory warnings from Sol Free Solitaire, but they didn't affect our games.
