Game Jam Stuttgart

​Build a Game in a Day for the Chroma Awards 🎮

​You’ll make a playable game from scratch: your own idea, your own world, your own characters. AI does the heavy lifting, and you bring the idea and mechanics.

​What you’ll do

• ​Come up with a game idea, from a tiny arcade loop to an interactive story

• ​Build it with Rosebud, turning prompts into a playable browser game

• ​Generate characters, props and worlds as 3D models with Meshy

• ​Give it a voice with ElevenLabs: talking characters, sound effects, music

• ​Submit your game to the Chroma Awards Game Division

​Who it’s for
Everyone. You don’t need to be a game dev or a programmer. If you’ve never made a game, this is the perfect first one. Experienced devs will find plenty of room to go deeper.

​What’s provided

• ​Tool credits from ElevenLabs, Rosebud and Meshy

• ​Lunch, drinks and snacks all day

​Just bring a laptop and your ideas.

​How it works
Sign up individually and form teams of up to 4 on the day. Spend the day building, then give a quick teaser of your game. No slides, just play. Afterwards, everyone plays each other’s games while the jury picks the winners.
