I love Angry Birds and Words with Friends. I would love new people to play with so feel free to PM me. Last night I downloaded Forever Frisbee. It's pretty good. You have to flick a frisbee and angle it through stars and hoops. The graphics are really cool.
I also played Restaurant Story for a while but when I couldn't leave the house without preparing my food I thought it was time to quit!
There's also a game called Tap Pet Hotel where you run a pet hotel. But, after my Restaurant Story obsession I'm really scared to go there!
