The theme for #PROCJAM 2025 is: ❄️ ☃️ COLD PLACES ☃️ ❄️
Let's Make Something!
PROCJAM - the Procedural Generation Jam - is a creative coding jam about making things that make things. This normally means using algorithms for creating things, from art, to music, to writing, to games. That could be a game that uses procedural generation to generate levels or stories, but it might also be an interactive art tool, a cool music maker or something else entirely.
Our jam is laid-back, relaxed and welcoming to newcomers, so whether you're an expert in building generative systems or curious about trying it out for the first time, you'll find yourself very welcome here.
We also have an amazing community-run Discord, if you want help, advice or just to talk to people who like this stuff too!
What could you make? Well, how about some examples:
A playful toy for generating things, like watabou's Mansion Generator! (PROCJAM 2018)
A game with procedural content in it, like Munro’s Aeronaut (PROCJAM 2020)
Algorithmic art, music or writing, like alambik's SLUMS (PROCJAM 2022)
Rules and Guidelines
PROCJAM just has one main rule: make something that makes something. You can use existing code and art, you can work in teams or alone, you can start early or submit late. We highly recommend taking your time and spending the week doing something that's fun for you, and sharing your progress with the community as you do it!
- You can start before the start date, and finish after the end date - contact us on Twitter for a 'late' submission. Don't overwork, and take breaks!
- You can use existing code/art/writing/anything or even continue an existing project. Feel free to add something generative to a game you're making and submit that!
- We welcome all kinds of submissions. No entry is too small or too big for this jam. Whether this is your first generator of your hundredth, we welcome what you've made, and we all want to see it.
- PROCJAM has no winners and no losers. We try to highlight and celebrate all our entries. We're all here to make things!
The use of generative AI (that is, tools such as ChatGPT, Midjourney or Copilot, or tools built on similar models) in entries is not permitted in the jam.
Ultimately we can't know 100% if you're using it, so it's very much an honour system which we hope you'll all respect. There are lots of other communities and events supporting that kind of work if you want them, but PROCJAM isn't.
