Spring Game Jam @ Matfyz 2024 – Green Edition 🥗

Hosted by ragnor8kpsychedeliaAmanita Design


The art which hides the theme for this year’s game jam was done by the wonderful Veronika Zacharová from Amanita Design.

We will officially reveal the theme at the beginning of the Game Jam.


The Matfyz Spring Game Jam 2024 is a traditional 48h hackathon for making games organised by Gamedev at Charles UniversityThis year’s main partner is Amanita Design, who will have developers and mentors 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 2024 is for you.

This year, we would like to invite our jammers to create games which tell us something about people’s connection with nature.  Video games have great power to help us see the world’s future in various ways, and we can harness it! You are free to interpret the (secret for now!) theme in any way you like, fun, or serious. We are excited to see you imagine our future through games! 

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 2024!

This year’s jam limit is 85 participants, so join quickly! Only the first 85 joined on itch.io will be allowed to enter the real-life site, make sure all your team members are here!


The game jam will be hosted by Gamedev at Charles University at the Malá Strana building on Malostranské náměstí 25, Prague.  We will provide each participant with a comfortable seat for work, internet access, basic kitchen appliances, and some basic refreshments to enjoy the jam.
