Open Jam is a game jam with 🖤. At Open Jam, you build an open-source video game over the weekend, rate other creators’ games, and compete for delicious open source karma. Open Jam is a game jam that promotes open source games and game creation tools.
Using open source tools is highly encouraged!
Last year's Open Jam 2021: https://itch.io/jam/open-jam-2021
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! Open Jam is all about open games and open game development.
Open Jam will be a 80 hour Jam based on a theme.
Here are Open Jam’s guidelines:
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.
There are too many amazing open source tools to list on this page, but here is a categorized list of many to get you started:

If you want to suggest an open source tool used in game creation email firstname.lastname@example.org and I'll do my best to get it added to the list above.
After judging has completed, the top three games combined score of Overall + Open Source Karma categories will be declared the winners. Your game, your source code, and your contribution to open source are an even bigger prize. There are no monetary or physical rewards in Open Jam.
Open Source Karma
Open Source Karma will be awarded as points on each game by the Jam Hosts based on the following score table.
