I am a real solitaire fan and the App Store contains a lot of good solitaire card games. However, when I was younger I played a variation of this wonderful game called 'Russian Bank'. This wasn't available in the App Store at the time and I started my won klondike project called 'Klondike Battle'. This game is now available in the App Store and is unique in its kind. Why? Because you play against an opponent instead of on your own. Using two decks of cards (1 per player) you can use the cards of the other player as well. Until now a few thousand people downloaded this game world-wide and its available for free on the internet at: http://www.nifty-inspirations.com or you can buy it in the App Store at:Klondike Battle There is also a HighScore leaderboard so you can compare yourself with others! I wanted to share this and hope you have as much fun as I have with the game!
