[:en]Biggest game jam in central Europe![:]

Slavic Game Jam (SGJ) is an event focused around game development, which at its core has the 48-hour long jam. During the jam, participants cooperate to create games following a common theme.

SGJ aims towards providing a competition-free, friendly environment for jammers. We invite everyone interested in game development to take part. SGJ is a perfect opportunity for the community to improve and expand. Moreover, it stimulates innovation in games, enables knowledge sharing and offers opportunities for experimentation.

For the past five years, we’ve strived to create an engaging, enjoyable event for participants from different countries. Each edition brought new ideas and improvements, but also new challenges. This year we’re all going through an unprecedented change, so SGJ is changing as well: SGJ 2020 will be hosted online for the first time!

We know many of you would love a classic SGJ experience, but for now that has to wait. Fortunately, with the help of our wonderful community, we can still keep the Slavic vibe up. Socially distant but virtually together, we’re gonna create amazing games! Join our ever-growing SGJ family online and let’s make it happen 😉

SGJ 2020

Whether stationary or online, Slavic remains true to its heart. However, the new formula requires some adjustments. The biggests one is: SGJ 2020 is free of charge! Yes, no need to buy tickets and make travel arrangements. You can enjoy the game jam with all the comforts of your home, for free.

We’re gonna do our best to recreate the core jam experience, i.e. keynote, lectures and Hyde Park. Sharing gamedev knowledge and playing together are essential parts of every Slavic Game Jam. And as always, your ideas and creativity will make them even better.

If you’re already a part of our community, you’ll be happy to know that many things stay as they were. SGJ 2020 remains a competition-free, 48 hours long game jam. Teams will create games following a common theme. Anyone can participate, from beginners to professionals.

 We are pleased to announce SideFX is sponsoring Slavic Game Jam 2020 by providing a free 2-month Houdini Indie license to every participant. Houdini Indie’s procedural node-based workflow offers a smarter way to create high quality game art. Houdini technology is used by AAA studios to take their games to the next level and now this procedural power can be yours.

Houdini’s procedural workflow can help you achieve stunning assets without hours of mundane work as well as keep you up as you automate repetitive tasks, making it easier to quickly generate larger amounts of quality content.

Request your license as soon as possible to learn and use Houdini before the SGJ and create amazing art during the jam.

Please note: the two-month period starts upon registration, not after you downloaded the software.


The originator of the Slavic Game Jam is KNTG Polygon, a student scientific association from the Faculty of Electronics and Information Technology at Warsaw University of Technology. Polygon bravely unites university gamedev since 2009, and right now it includes  over 400 registered facebook users and about 100 people regularly attending weekly lectures and workshops. For the last few years the association was responsible for organizing PolyJam – Warsaw edition of Global Game Jam. Polygon is also organizing Game Dev Fest which gathers many gamedev experts to share their knowledge and experience acquired over many years of work.
