I invite you to check out my brand new app Klondike Solitaire Collection. The app features three different solitaire games (a version of the classic Klondike plus two related games Whitehead and Agnes), all implemented with high-quality retina graphics and in-game instructions and hints. Best of all, the app is free so even if you're not a regular card game fanatic, you have no excuse not to try out the games!
