Game Off is an annual game jam organized on itch.io that invites participants to create a game inspired by the theme of clichés, such as "a blast from the past" or "skating on thin ice," by the submission deadline of December 1. Participants can use any game engine or programming language to build their games and must store their source code on a public GitHub repository. The event encourages creativity with clichés from various sources, including movies and video games, and offers a platform for newcomers to explore game development with numerous open-source resources available. Once the jam concludes, submissions are rated on categories like Gameplay, Graphics, and Innovation, with standout entries highlighted on the GitHub Blog. The Game Off community on itch.io and a community-run Discord server provide opportunities for collaboration and support, while Git and GitHub resources are available for those unfamiliar with version control or the GitHub platform.
