The Amazon App Store is an application for Android that works just like the Google Play Store. From your Android phone, simply download the Amazon App Store and get access to many mobile apps and games while logged in to your Amazon account. Among other things, this system allows you to use the Amazon Coins digital currency (100 Amazon Coins = 1 euro). You can thus buy applications and mobile games at reduced prices (because the more you buy Amazon Coins, the more you increase your purchasing power in euros).
Note that this application cannot be installed on iPhone, it is not compatible with iOS, only with Android.
All mobile games that would be available on the Google Play Store are accessible from the Amazon App Store. This allows an extremely complete choice. Which means you can take a look at the list of Android games, you're bound to find it on Amazon. Remember that this won't be the case with iOS games, if the game only exists for the iPhone for example.
So, which Amazon game will you choose?
