Please note: This version requires Wi-Fi to download.
The pigs are hungry and eggs are on the menu; the survival of a flock of friendly, colorful birds is threatened. When the greedy green swine raid the flock's nest, the unexpected happens: a rage is kindled within the birds that only revenge can quench!
Your job is to help the Angry Birds seek vengeance against the pigs with the help of a finger-powered slingshot, a good dose of strategy, and a bit of luck.
The goal of the game is to catapult each bird toward the pigs, who hide behind a variety of destructible materials. Use each bird's unique skills to break through crates, boards, stone, ice, snow, glass, boulders, and dynamite to vanquish the devious pigs.

This is a fantastic offering for the Amazon Appstore FAOTD. Still, in general we continue to be disappointed with the program. It began promisingly enough, with Angry Birds Rio, but we've gotten tired of the endless games or niche apps, and especially apps which have no uptake in Google Play, and seem to be FAOTD as a desperation move by the developer. We'd like to see free versions of say, Office-compatible software or useful utilities such as CalenGoo instead of niche apps or endless games.
what it means to developers.
Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
