Every platform needs a breakout game to push it to new heights, and for iOS, that game was Angry Birds.
The simple idea of slingshotting disgruntled avians towards teetering towers of bricks, stones and pigs was the perfect fit for touch controls. It was helped along by challenging yet easy-to-play levels that could be attempted — and re-attempted — in a minute. Adding to the challenge was each level’s star rating, meaning you could still perfect your score and beat your friends.
