The theme is:



Spring Game Jam 2023 is a traditional 48h hackathon in making games organised by Gamedev at Charles University in collaboration with this year's main partner and sponsor Beat Games, who will have members present at the jam, so you can stop by and chat with them!

Anybody can sign up and compete for honor and fun. Game jams are here to bring people of various skills keen on game development together; an opportunity to meet new friends, acquire new skills, try out new ideas, and be creative. Whether you are a beginner or a seasoned game developer, Spring Game Jam 2023 is for you.

Our game jams are open to anyone willing to create a video game. We are glad that the atmosphere at our site is friendly and all participants share their experience and help each other to develop a game.  Furthermore, game development lecturers and industry professionals will be available on-site to help you solve your issues during development.

At the end of the jam, all participants will be able to vote for their favourite game from the jam receiving a PEOPLE’S AWARD of Spring Game Jam 2023!

This year's jam limit is 100 participants, so join quickly! Only the first 100 joined on will be allowed to enter the real-life site, make sure all your team members are here!
