This jam is now over. It ran from 2025-08-22 19:00:00 to 2025-08-31 19:00:00. View results


WHY?

It's that time of year again! It's olcCodeJam Time! It doesn't matter what your level of experience is, the CodeJam welcomes all to have a go at a project with a theme and a deadline. This is a CodeJam - which means you don't have to submit only games, but applications, demonstrations and other projects are welcome, as long as they adhere to the theme. The olcCodeJams usually get a wide viewing audience, so it's a great opportunity to take some pride in your work and show your stuff!

WHEN? - Starts 22 August 2025 @ 8pm BST

Why not join our discord server and chat about code with thousands of others: https://discord.com/invite/WhwHUMV

WHAT?

The theme will be announced when the jam starts. Wait for it here, or very likely there will be a theme reveal livestream, link to be posted soon.

HOW?

Its easy! 

  1. Register with itch.io and join the CodeJam. This will allow you to keep up to date with CodeJam activity. 
  2. Wait for the CodeJam to begin, and the theme to be announced.
  3. Start Programming!
  4. Submit your entry before the deadline. Once this passes, your entry is locked and is ready to be judged!
  5. During judging, try as many other entries as you can, stream them, post the ones you like - remember the aim is to encourage people to have fun, and receiving a rating is a great feeling!
  6. Once the judgment period ends, the winner will be announced!

RULES!

  • Keep it clean, safe for work and reasonably family friendly.
  • If you use assets you have not created, please credit them appropriately and in accordance with their license.
  • Your entry should be original for this Jam.
  • Unlike javidx9's YouTube channel, entries can be in any programming language or framework, so you are NOT limited to using olc::PixelGameEngine (though you can, and it compiles for browser now, just saying :P ), so feel free to create your entry however you want. HOWEVER: Past CodeJams have shown that browser based entries on average get more ratings because they are easy to access. This is NOT compulsory.
  • The winner is decided by points awarded by the public and the community.
  • A judges choice award is available. It's worth 891 internet points! Budget cuts this year...
  • Unless otherwise announced, all dates and times, especially the deadline, is final.
