The full version is now available free for Android users. Angry Birds is a very simple game, but as with all good games the devil is in the detail. Use a catapult to throw birds with unique powers against a range of egg stealing pigs in a variety of fortresses. Adjust the birds trajectory for maximum impact/damadge. The challenge is to compete the task of ridding the planet of Pigs in as few birds as possible. This challenging physics-based gameplay requires a bit of logic, skill, and luck to crush the enemy. Highly addictive and the No.1 game download in most countries for a very good reason.
