Hello, and welcome to the home of the (not really) bimonthly game jam for libre games, LibreJam!

At the beginning of every other month, the jam begins, with a unique theme being released to add extra challenge. Participants have two weeks to develop and publish their game, working solo or in teams. Once time is up, all games are published to the site for others to view, and ratings are opened for seven days, before a winner is announced.

Once your game is finished, submit it using the Jamgaroo page for the relevant jam. Please include a brief description of your game and instructions on how to play it. If you're submitting a Git repository, make sure to create a tag on the commit you're submitting, so newer commits won't be confused as your submission.

Note that all submissions are publicly viewable on the Jamgaroo page, and later on this site. Others will be able to view your submission as well as reply with their own comments and feedback.


Anyone can submit ratings for games, not just jam participants. You can submit ratings on the Jamgaroo page for the submission. Ratings are accepted until the end time given at the top of the page, after which ratings for all games are tallied and winners are announced.


Come and chat with us in the #librejam IRC channel on LOHIRC. Here you can brainstorm, team up and chat about development! If you have a question about the jam, come and chat in the IRC channel.

In addition to the above rules, there are some guidelines that you might want to keep in mind while developing your game. These are not mandatory, but they're generally good advice for helping you create an end product which is fun for everyone:
