GameOn is an Amazon service allowing developers to host in-game events where users can compete for bragging rights and prizes. GameOn allows developers to use RESTful APIs to host single-round, asynchronous competitions in any of the countries where AWS exists, and is platform agnostic allowing competitions on multiple device types. Competitions can be created by developers using the admin console, and/or created in-game by end users if developers allow it. Developers can award in-game prizes to players in all Game On supported countries and real-world prizes, which will be coming soon to US customers only. Developers can also use the matchmaking service to ensure fair and fun play.
