You'll have to install the Appstore client on your device since the promotion is only through the Amazon Appstore. But that is no biggy.
To get apps from Amazon, you'll need to enable unknown sources for app installation in the system settings. Don't worry—Amazon's page will walk you through it.
This time you'll get content like Sonic All-Stars Racing, My Alarm Clock, Carcassonne, and Flightradar24 Pro.
All the apps will remain in your cloud library. >>
