If you like Solitaire, this is the one for you! We've got the basic Klondike version (3 cards or one at a time), Spider, and FreeCell. Much of the game is automated, but you can undo the plays (if you need to reach a card that's in the completed pile, for example). Also, you can turn the autoplay feature off if you prefer.
This is similar to the Solitaire game that came bundled with Microsoft Windows, but it's new and improved. You can either click and drag the cards to play, or you can double-click cards that you want to play, and the system will place them in the optimal location.
