The GitHub Game Off, a game development competition themed around concepts like forking and branching, concluded with over 1337 forks and nearly 200 playable games submitted. Expert judges evaluated each entry, culminating in the announcement of five winners, six runners-up, and seven honorable mentions, all of which are free to play with publicly available source code on GitHub. The winning games featured diverse mechanics, from a platformer where an android gains powers by merging enemy code to a minimalist 3D game focused on dodging branches. Participants are encouraged to continue their projects in the Mozilla Game On competition, which offers categories like Hackable Games, Multi-Device Games, and Web-Only Games, with a submission deadline of February 24, 2013. The event, organized by GitHub's Lee Reilly, aims to inspire interest in game development and coding through open-source collaboration.
