Copyleft Games

Tools and engines for making games

Copyleft Games Group is dedicated to helping developers create games without restrictions of proprietary licenses or royalty fees. Our goals for Google Code-In 2019 include:

  • Reworking our engine for better cloud support
  • Integrating VR support
  • Classroom "Learn how to code" material for ages 8-12
  • Migrating our collaboration tools to MIX

We focus heavily on community participation and consider this a major factor in selecting our finalists and grand prize winners. Several of our past Google Code-in grand prize winners have demonstrated strong communication skills but were new to software development.
