The survival of the Angry Birds is at stake. Dish out revenge on the green pigs who stole the Birds' eggs. Angry Birds features hours of game play, challenging physics-based castle demolition and lots of replay value. Each of the levels requires logic, skill and brute force to crush the enemy.
Angry Birds on Chrome features a new web-exclusive episode called Chrome Dimension, which you can access by hitting the Chrome balls hidden in other levels.
We also have the first three episodes of the award-winning Angry Birds Classic game and the Christmas-themed Seasons Greedings episode from Angry Birds Seasons. Close to 200 free levels and hours of gameplay!
In addition, you can now use Mighty Eagle to power your way through difficult levels! This one-off purchase lets you destroy as many levels as you want, though you can only use it once an hour. The Mighty Eagle also includes all-new game-play goals and achievements! You can try Mighty Eagle for free during the first 21 levels!
