Theme: The Future


Open Jam is a game jam with đź–¤.  At Open Jam, you build an open-source video game over the weekend, rate other creators’ games, and compete for a chance to have your game featured at All Things Open, a premier open source conference.   We wanted to host a jam that promotes open source games and game creation tools. That's why we're teaming up with to bring you Open Jam, a game jam dedicated to doing just that.

Using open source tools is highly encouraged!

Last year's Open Jam 2018:

How is Open Jam Different?

What we want to do with Open Jam is promote not only open source games, but open source game creation tools as well.  This jam encourages use of open source game engines, authoring tools, and platforms, and Creative Common assets, and to link those tools in your submission.  Anything open source in your game creation process is encouraged! That is why we are hosted by and winners games will be featured All Things Open conference.  Open Jam is all about open games and open game development.

How does it work?

Open Jam will be a 80 hour Jam based on a theme.  It will run September 27-30th

Here are Open Jam’s guidelines:

  • You can use any tools to create your game and it can run on any platform, open source tools and platforms are encouraged.
  •  There is a new voting category for "Open Source Karma" based on open source friendly your game is i.e. how many open tools you used, if your game runs on an open platform,  and a nice github repo.  See table below.
  • It is very important to list all the open source tools you used and link to your git repo in your game entry, so you can get credit for your Open Source Karma
  • Games source should be available and licensed as open source.
  • You can create or use your own assets or use existing, openly licensed assets (e.g., Creative Commons).
  • You can work solo or on a team. 
  • The theme will be announced at 1:00 PM September 27th (US Eastern).
  • Judging will run Sep 30- Oct 8th and will be peer-based.
  • Games require a minimum of 10 ratings to place in the top 3
  • The top three games will be featured and playable at All Things Open.
  • Games must be original for Open Jam, they can't be entries submitted to other game jams or forks of other games.

If you’re looking for open source game creation tools to try, we have a list below.  We encourage any openly licensed game engine, framework, or library, but it is not a strict requirement.  For non-code assets like music and sprites, anything marked with Creative Commons is welcome, or you can create your own! Make the greatest game you can by bringing together the best of the open world.

At the end of the weekend, release your game and code to the world, play other participants' games, and rate them.
