Game Off is an annual game jam challenging individuals and teams to build a game during the month of November. Use whatever programming languages, game engines, or libraries you like. We'll announce the secret theme on Nov 1st at 13:37 PT.

While you're waiting, you can check out some of the top games from previous years.

  2. Join the jam. Hop onto the itch.io Game Off page. If you don’t already have an itch.io account, you can sign in with your GitHub account.
  3. Create a public repository. Store your source code on GitHub—open-source magic at its finest. Push your game before December 1 at 13:37 PST.
  4. Submit your game on itch.io. Once submitted, you’ll be able to play other entries and cast your votes!
