It's interesting how an app based on math and logic can tempt users to hit the replay button and hunt for new levels and new challenges. With its well-designed, intuitive interface, Angry Birds proves to be a game you'll want to keep playing.
Angry Birds gets off to a good start, with onscreen guidance for each new level and new feature. Even novice users won't need long before they're ready to play. We liked how it introduces the players to the game and explains why the birds are so angry and why they are after those evil pigs: it uses two simple pictures, which is quite enough to get the feel of it.
We also liked how the app entertains and keeps you busy: as you advance and reach new levels, you unlock additional features, and new birds join your team. Diversity is the key. As soon as new birds with new abilities join the fight, you'll be forced to use your math and logic skills to reach the next level. Yes, math can be fun, as Angry Birds clearly demonstrates.
Overall, Angry Birds could easily become your favorite time-killing app, and we recommend it for any user level.
