Stand Up! All the Angry Bird fans that is. Just in case you do not know, Amazon is offering Rovio’s Angry Birds Rio today for free in the Amazon AppStore for Android. Additionally, this version will be ad-free. So now there is no excuse for you not completing that one level, where you always say, “that stupid Ad got in my way.” I have been playing Rio for a while now, and it’s probably my favorite Angry Birds edition. Anyway, hit up the link below to grab the application while it’s still free. Btw, what’s your favorite Angry Birds edition?
