GitHub Announces SHIFT Theme for Annual Game Off 2026 Jam

Understanding the Theme and Rules

GitHub has announced the theme for its fourteenth annual month-long game development event, known as Game Off 2026. This year, the designated theme is SHIFT. Participants are encouraged to interpret this word in various ways, such as changing perspectives, altering dimensions, shifting bits, or working a night shift. Developers can apply the theme strongly or loosely, depending on their creative vision.

The event is open to anyone, whether they are building their first game or their fiftieth. Developers have the option to work completely alone or form teams. The rules remain intentionally relaxed to keep the environment fair and enjoyable. Participants are expected to begin their projects during the jam, though starter projects and templates are permitted. The vast majority of the work must take place during the official submission period.

Brainstorming and Technical Tools

For participants seeking inspiration, the organizers suggest several concept ideas. These include single-button games using only the Shift keys, racing games where shifting gears alters physics, or puzzle-platformers that involve moving between overlapping realities. Other concepts range from convenience store night-shift horrors to programming puzzles based on bitwise shifts.

Developers can use any programming languages, game engines, frameworks, libraries, and tools that suit their projects. The source text notes several popular engines to explore, such as Godot, Unity, Unreal Engine, Phaser, Pygame, and Bevy. Participants may also use AI-assisted development tools, provided they disclose their use of artificial intelligence upon submission so that others understand how the game was made.

Submission Guidelines and Deadlines

To participate, developers must have a free GitHub account and a public repository where they store their game’s source code. Participants also need to register on the hosting platform itch.io, where they can sign in using their GitHub credentials. The deadline for building, pushing code to GitHub, and submitting entries on itch.io is December 1, 2026, at 13:37 PST. The organizers explicitly note that pushing code to GitHub does not automatically submit the entry to the jam.

Participants are free to choose any license for their work, with open source being encouraged but not strictly required. Developers can also use open source, commercial, commissioned, or original assets. The event emphasizes starting with a single mechanic and a single playable level before expanding the scope.

Community Voting and Evaluation Categories

Once submissions close, the evaluation phase begins, allowing participants to play and rate the games created by their peers. This community-driven voting process helps determine which projects receive bragging rights. Games are evaluated across five distinct categories: overall gameplay, graphics, audio, innovation, and theme interpretation.

Voting concludes on January 1, 2027, at 13:37 PST. Following the conclusion of the voting period, the winners will be announced on the official GitHub Blog and across GitHub social channels. The event provides a collaborative space for both beginners and experienced developers to experiment with unusual hardware, old consoles, or modern frameworks.
