Slavic Game Jam (SGJ) is an event focused around game development. It takes place each year in Warsaw, Poland. At its core lies 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. The event comes with many lectures and workshops, a pre-party and other activities.

Each edition is organized and run by volunteers. They strive to create an engaging, enjoyable event for participants from different countries. SGJ is a perfect opportunity for the community to improve and expand. Moreover, it stimulates innovation in games, enable knowledge sharing and experimentation.

The originator of the Slavic Game Jam is KNTG Polygon, a student scientific association from the Faculty of Electronics and Information Technology, which bravely unites university gamedev since 2009. Right now it can be proud of 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.
