This yearâs Game Off theme is clichĂ©!
Cli-ché
noun
1. a phrase or opinion that is overused and betrays a lack of original thought.
If you’ve heard a phrase a million times, chances are it’s a clichĂ©. For example, âa blast from the past,â âplay your cards right,â âitâs an uphill battle,â âavoid it like the plague,â and âdonât deploy on a Friday.” You catch my drift?
Take one (or more) of your favorite clichés and use them to inspire your game.

Game Off is our annual game jam challenging folks to build a game based on a theme.
Voting will open shortly after the jam ends and is open to everyone whoâs submitted a game.
Entries will be rated on the following categories: Overall, Gameplay, Graphics, Audio, Innovation, and Theme Interpretation. We’ll highlight some of our favorites games on the GitHub Blog, and the world will get to enjoy (and maybe even contribute to or learn from) your creations.

You can use whatever game engine you like (or none at all), whatever language you like, and build for whatever you platform you likeâWeb, Windows, macOS, Linux, and mobile. Heck, weâve even had NES and Commodore 64 submissions in the past.
Looking for a teammate or to offer your skills to an existing team? In need of advice on what language or game engine to use? Ask in the Game Off community on itch.io, or in the community-run Discord server.
Good luck, have fun, and

Open source software is critical infrastructure, but itâs underfunded. With a new feasibility study, GitHubâs developer policy team is building a coalition of policymakers and industry to close the maintenance funding gap.
That idea you’ve been sitting on? The domain you bought at 2AM? A silly or serious side project? This summer, we invite you to build it â for the joy, for the vibes, For the Love of Code đ§Ą
