The GitHub Game Off, a recurring game jam event organized by GitHub, is set to return next week, inviting participants to submit their creative game projects. The theme and specific details of the event will be announced on the GitHub blog on March 13th at 9 am PDT, and there might be unexpected elements introduced this year. Participants and followers can keep up with the event using the official Twitter hashtag #ggo15. The announcement was made by Lee Reilly, a Senior Program Manager at GitHub Developer Relations, known for his involvement in supporting developer communities and organizing hackathons and game jams.
