DESCRIPTION: The hit game, Angry Birds, has a sequel: Angry Birds Rio. It's played like the original game: pull the sling shot back, and watch the bird fly. Angle it right, and you'll hit the boxes or the cages. Once all the cages have been destroyed and the birds set free, the level is over. Extra points are awarded for the birds you don't use. However, run out of birds before the cages are gone, and you've lost the level. You can replay the levels as much as you like - either to improve your score or to get the hang of the game.
