From Solitaire Forever:
Klondike is everyone's favorite solitaire game. Enjoy it fast, smooth, and beautiful, for free. Klondike Forever allows to set game rules including option for unlimited undo/redo. It has full screen mode. Highlight playable cards and cards of any rank. You may use single or double click auto move and sticky click options. Peek at hidden cards.
It is very clear, bright and FAST. Also you are not constantly frustrated as with some others (such as Full Deck Solitaire). It is the best ever, the best I've ever seen. On top of all that, it is free. What more can one wish?
Nothing at all.
This is the best solitaire app I've ever seen, all things considered. It is Klondite Forever is easy for the eyes (bright and clear), for the mind (it responds quickly and moves cards through clicks: many apps, e.g. Full Deck Solitaire, are slow and you waste time moving the cards manually, which is frustrating in itself).) and for the heart (you don't always get frustrating hands as with some apps, and you get an applause when you win). I've never seen anything as good, and in fact can't imagine anything better.
