Amazon said the highly anticipated Angry Birds Rio for Android debuts today, exclusively in the Amazon Appstore and customers can even download it for free for a limited time.

In fact, the Amazon Appstore will offer customers a paid app for free every day, Amazon said in a statement.

For the first time ever on the Android platform, ad-free versions of Angry Birds and Angry Birds Seasons will launch today exclusively in the Amazon Appstore.

The Amazon Appstore also features a selection of bestselling and new apps from top developers, including Pac-Man, Doodle Jump Deluxe, Evernote, WeatherBug Elite, Zagat to Go, TweetCaster Pro and more.

The Android platform's openness provides a great opportunity to reach new customers, said Mikael Hed, CEO of Rovio, the maker of Angry Birds. We are thrilled to offer the Angry Birds suite of Android games using the easy and trusted shopping experience that Amazon is known for.

Developed in conjunction with Twentieth Century Fox, Angry Birds Rio features the animated stars of the studio's upcoming motion picture, RIO, debuting in theaters worldwide on April 15. Angry Birds Rio will launch with 60 dedicated levels, with more content to follow via app updates.

In Angry Birds Rio, the original Angry Birds are kidnapped and taken to the magical city of Rio, where they eventually escape their captors and set out to save their friends, Blu and Jewel - two rare macaws and the stars of the upcoming Fox motion picture, RIO. 

Angry Birds is a puzzle video game developed by Finland-based Rovio Mobile in which players use a slingshot to launch birds at pigs stationed on or within various structures, with the intent of destroying all the pigs on the playfield. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apple's iOS in December 2009.

Since that time, over 12 million copies of the game have been purchased from Apple's App Store, which has prompted the company to design versions for other touchscreen-based smartphones, such as those using the Android operating system, among others.

Rovio said that Angry Birds has been downloaded 100 million times, doubling sales numbers from the previous three months.
