Update: The 2019 Game Off is over! View all the winning entries and results by category as voted by the developers themselves 💜

Game Off is our annual game jam, where participants spend the month of November creating games based on a secret theme. 

This year’s  theme is LEAPS AND BOUNDS.

You’re welcome to interpret the theme however you wish, but if you need some ideas to kickstart your creativity, maybe your game could:

  • Make your character evolve to overcome challenges
  • Add obstacles to test your hero’s ability to leap into action
  • Deduct points for anything going out of bounds
  • Duck, dip, dive, and dodge an enemy that’s changing or moving rapidly
  • Take place in the year 2020, the next leap year

Maybe the year 2020 will lead you to think about hindsight being 20/20, and that’ll inspire even more ideas around time travel, decision-making, or something else. 

Let your imagination run wild and create a game loosely-based or inspired by that theme using whatever game engines, libraries or languages you prefer before December 1st, 13:37 PT.

Good luck and have fun!

🕹 Help—I’ve never created a game before!

With so many free, open source game engines and tutorials available online, there’s never been an easier (or more exciting!) time to try out game development.

Are you…

  • Into JavaScript? You might be interested in Phaser.
  • Comfortable with  C++ or C#? Look at  GodotUnity and Unreal Engine.
  • Proficient with Python? Check out Pygame or  Godot (Godot uses GDScript, which is similar to Python).
  • Dangerous with Java? Take a look at libGDX.
  • In love with Lua? Check out LÖVE or Defold.  Like retro games too? Drop everything and check out LIKO-12!
  • Experienced with Ruby? You might like DragonRuby Game Tookit - free for all Game Off participants (details).

Do you really like retro games? Maybe you can…
