Card Game Idea

Has anyone played the card game in Knights of the Old Republic? Are there any PocketPC games like the card game played in it? (Forget the name of it at the moment)
For those who haven't played it, it's similar to BlackJack. You get to pick 10 cards from your personal deck. In the game, 8 of them are picked randomly for you, two stacked on each other. You then take turns, with other cards being drawn. You can choose to put down one of your cards that range from -5 to +5, with some special cards allowing you to change plus or minus. The object is to add up to 20 without going over.
