Hey Codeforces!

We've been creating the Cloudflight Coding Contest (CCC) with all love to code for years. Next edition is coming up on October 23rd, 2026!

You are welcome to participate online, or on-site if you are around at one of our 40+ locations across Europe! Participation is free, you just need to register here: https://codingcontest.org/

If you are a beginner — pick the #school track, and if you wanna challenge yourself — pick the #classic. And if you are into training your own AI — pick the #data/ai track!

You can also team up with friends — up to 3/5 members depending on track. You can also find teammates in our Discord Community: https://discord.com/invite/7Sb5RCa6J

To prepare for the competition and have fun, try our games on the platform.

Looking forward to a day of awesome coding!
