GitHub organized a game jam called "Game Off" in November, inviting participants to create web-based games inspired by themes such as forking, branching, cloning, pushing, and pulling. Participants, either individuals or teams, could use open-source libraries and frameworks to develop their games, with submissions required to be playable in a browser and hosted on a fork of the github/game-off-2012 repository. The winners would receive iPads or equivalent Apple Store credit, while runners-up would get GitHub swag, and all participants would earn a limited edition Coderwall badge. The judging panel included industry professionals like David Czarnecki and Eric Preisz, and games had to be submitted by December 1st, with winners announced before Christmas. Participants were encouraged to follow GitHub on Twitter for updates and to engage with the community using the hashtag #ggo12.
