Amazon is able to bring the games and apps, including their in-app purchases to users free under a new business model. The company has worked with developers and will be paying them per minute of play in order to have the developers waive the normal fees. Amazon will be paying these costs, and not passing them onto the user in anyway.
In Amazon Underground, you will find 100% free versions of popular titles like Frozen Free Fall, Star Wars Rebels: Recon Missions, OfficeSuite Professional 8, Goat Simulator, Angry Birds Slingshot Stella and many more.
