Rewards are prevalent game design elements in gamified environments. Rewards are helpful tools to keep players engaged and encouraged to perform tasks. However, implementing a reward system from scratch in every gamified environment, such as citizen science games or educational applications, can be time-consuming. This article presents FORGE, a Framework for Organizing Rewards in Gamified Environments. FORGE is a free and open-source framework built to be easy to install, easy to integrate, flexible and customizable. It was designed to be used in a variety of different environments and scenarios, such as games, training software and interactive websites. The FORGE framework comes with two sample applications, a simple game concept and an educational web application, to demonstrate its capabilities and serve as an entry point for new adopters.
