The next generation of Amazon Underground
Born in 2015, Amazon Underground provided access to more than 450 free applications. In exchange for your personal data and the creation of an Amazon account, you could play usually paid applications completely free of charge.
In fact, Amazon also financed in-app purchases by paying developers an amount based on the time spent by users on a given application. The service has since closed and Amazon now offers to download apps from the Amazon App Store.
The Amazon App Store and Amazon Coins
The Amazon App Store gives you access to a large number of free or paid games. The main interest of the Amazon App Store is to be able to use Amazon Coins (100 Coins = 1 Euro). This virtual currency can only be used to buy games or make in-app purchases at preferential rates compared to the game downloaded from another store. You can then earn Amazon Coins as you play your favorite games. Amazon regularly offers promotional offers to buy coins at a reduced price, especially during black friday.
