Game Off, an annual game jam, invites participants to create games based on a secret theme revealed on November 1, offering the entire month to develop their projects. This event provides an opportunity for both novice and experienced developers to build their first game or explore new technologies and frameworks, with last year's theme, "leaps and bounds," inspiring over 200 diverse game submissions. Participants are encouraged to use free and open-source game engines, such as Phaser, Godot, or libGDX, although it's not mandatory, with past entries utilizing a variety of tools including Unreal Engine, Unity, and even retro platforms like the Commodore 64 and NES. Organized by Lee Reilly, Senior Program Manager at GitHub Developer Relations, the game jam fosters creativity and community engagement among game developers.
