Angry Birds

The amazingly popular iOS game earned over two million downloads during its first weekend of availability on Android and despite myriad sequels and spinoffs, it is still a great game to play.
The Android version of Angry Birds is free, unlike the Apple release, with maker Rovio opting to stick a few adverts on it rather than charge an upfront fee. The result is a massive and very challenging physics puzzler that's incredibly polished and professional. For free. It defies all the laws of modern retail.
