GitHub's annual month-long game jam, Game Off, is returning this November for its 14th year, and the theme for 2026 is SHIFT. The announcement on the GitHub Blog notes that thousands of developers have taken part over the years, producing everything from polished platformers to deliberately strange experiments, and organisers say newcomers working on a first game are as welcome as veterans on their fiftieth.
The theme is deliberately open. GitHub suggests participants could shift gears, perspectives, dimensions or bits, work the night shift, or build a game in which the only usable buttons are the Shift keys. Both strong and loose interpretations of the theme are said to apply.
To help people get started, the announcement lists a set of concept prompts: a one- or two-button game controlled entirely by the Shift keys; a racing game where shifting up does more than change speed, with second gear reversing gravity, third slowing time and fourth removing the brakes; a perspective puzzler where rotating the camera turns walls into floors and shadows into platforms; a puzzle-platformer that jumps between two overlapping realities, where a broken bridge may exist in the other world along with whatever is standing on it; a shapeshifting adventure that inherits the abilities and weaknesses of the creatures and objects you become; a night-shift horror game in a convenience store with increasingly strange customers; a comedy detective game in which the player committed the crime and must shift blame onto unlikely suspects without contradicting the evidence; a programming puzzler that uses bitwise shifts to double or halve objects in size; and an adventure about persuading someone to cover your shift so you can attend a final boss battle. Other suggested directions include shifting tectonic plates, shape-shifting aliens, shifting alliances, shifting sands and an ambitious stick shift. The advice offered is to avoid overthinking it: pick one mechanic and one playable level and get those working before expanding.
Participation requires a free GitHub account and registration on the Game Off 2026 page on itch.io, which can be accessed by signing in with a GitHub account. Developers work alone or in teams, using whatever languages, engines, frameworks, libraries and tools they prefer. The game's source code must be stored in a public GitHub repository and pushed before the deadline, and the entry must also be submitted on itch.io by December 1, 2026 at 13:37 PST. Pushing code to GitHub alone does not count as a submission. Once submissions close, participants can play the other entries and cast votes.
Voting is open until January 1, 2027 at 13:37 PST, and entries are rated across six categories: Overall, Gameplay, Graphics, Audio, Innovation and Theme interpretation. Winners will be announced on the GitHub Blog and GitHub social channels shortly afterwards.
The rules are described as intentionally relaxed. A game must live in a GitHub repository, and while templates and starter projects are welcome, the project should begin during the jam and the vast majority of the work should be done inside the submission period. Licensing is left to the developer, with open source encouraged but not required. Solo and team entries are both accepted, and any tools and assets may be used, whether open source, commercial, commissioned or original. AI-assisted development is permitted; because the subject is sensitive and participants hold differing views, entrants will be asked when submitting about their use of AI so others can understand how a game was made.
No prior experience is necessary, according to the announcement, and many participants make their first game during the jam. Some use established engines and others build their own, targeting conventional platforms, older consoles, unusual hardware, terminals or calculators. Engines and frameworks highlighted as options include Godot, Unity, Unreal Engine, Phaser, Pygame, Bevy, LÖVE, Flame, Ebitengine, Defold, libGDX, HaxeFlixel, raylib, PICO-8 and TIC-80. A Game Off 2026 Community space is available for questions, progress updates and teammate searches, alongside a community-run Discord server, and GitHub points to its Git documentation, GitHub Docs and GitHub Community for those new to version control.
