The Brno Game Jam is 48-hours hackathon in making games organized by Herní Klastr. It doesn't matter if you are a beginner, professional or hobby game developer, anyone can join and try to create something amazing! You can have your team in advance or team up right on site - game jams connect people of various skills keen on game development. It’s an opportunity to meet new friends, gain new experience, try out your ideas, and especially - be creative!


Vote for one of the following topics in the registration form:

  • Brno legends
  • Brno underground
  • Sound giving direction
  • That one room
  • Shadow Brno

The theme with the most votes will be announced at the start of the jam.


The jam is taking place in KUMST creative hub Brno at Údolní 19. Yes! After a long time, finally a game jam on a dedicated location.

We'll take care of a small refreshment - baguettes, toaster, drinks (soft drinks, energy drinks and water) and of course a lot of coffee. There will be available showers and room for sleepover, so take your mats and sleeping bags if you are planning to dare to sleep.

Even though this is a non-profit event, the entrance is FREE. However the capacity is limited so don't hesitate with the registration.


April 14-16, 2022, Friday to Sunday from 18:00 to 18:00.

Detailed schedule will be available later.

>> WHY

The biggest reward of each game jam is the creation itself. However we also have some physical prizes prepared for the best project. You can win free tickets to the Game Access Conference.

On the site, there will be professionals from the game industry providing feedback and mentorship. Use that in your advantage.


Follow these two simple steps:

  1. Login (or register) to your account and click on 'Join jam' above
  2. Register yourself by filling in the Google form where you can vote for the jam theme

Each attendee registers individually, regardless teams.


Games will be evaluated in two categories:

  • Jury pick: Selected reviewers picking together the winner of the jam
  • User's choice: Contributors reviewing other submissions and rank them in various categories

During the review period, it is not possible to update the submission. However, it's possible to modify the submission's webpage (so don't waste time with that before the deadline).

Results are to be announced on April 22, 2023 online on Discord. Feel free to join us.


  • Max team size: 4 member. Each member needs to be assigned to the project as co-author. Note that members can be added even after the submission, but before the voting ends.
  • The build must run either on Windows 10 based computer, Android 6.0+ mobile device or WebGL. If you're targeting VR, make sure SteamVR or Oculus Quest is supported.

>> Q&A

  • I registered but something came up and I can't go. What should I do?
