imageRocket21 is a WP7 game that’s a mix of Blackjack and Solitaire. You have 4 hands to build upon to try to hit a blackjack. If you bust you lose points and if you hit you get points. You’re also competing against a clock. Add to this, there’s a global leaderboard that’s great to see how good or bad you are – and there are some people that are really good cause I’m not even close to their scores. This game was originally $.99 but is now free (and it appears as though the paid version was pulled). Anyway, it’s a lot of fast card action and if you’re into card games at all you should give this one a try. You can pick it up and play a fast hand in your spare time but it is very addictive so you’ve been warned.
