An in-content challenge platform and method for generating single user challenges within multiplayer games (and other media) is disclosed. The in-content challenge platform provides various in-content challenges and prize promotions to users for completing specific win conditions within an instance content (e.g., a video game, a fitness application, a streaming video service, etc.). In some embodiments, the platform can be integrated directly into the game itself. In other embodiments, the platform is seen as an overlay to the game. In still other embodiments, the user can interact with the platform through a separate piece of software that is reached via a client device independent of the content or a third-party system providing the content itself.
