Registration for the Cloudflight Coding Contest (CCC), Europe’s largest onsite coding showdown on October 23rd, 2026, is not yet open. However NOW is the right time to discover the contest and dive into the games from the past years. After all, practice makes master. Only then will you be completely ready to join coders from dozens of international locations to tackle epic challenges and connect with others.
New? This is how it works – Each year thousands of coders from all around the world simultaneously compete against each other in level-based coding games. With each level the difficulty increases and the individual contestant (or a team) reaching the most difficult level within the shortest time wins. The actual topic of each game remains secret until the event. Not even Cloudflighters know anything about the games, with the exceptions of a few game engineers, masterminds behind the challenges. However, we might share a few hints and teasers in our newsletter and via our social media channels.
The games are setup in a way that anyone from a student to the top notch expert can get a good challenge and a lot of fun. Pick one of the following paths and register:
- School: Perfect for young coders to shine.
- Classic: Test your wits with mind-bending puzzles.
- Data/AI: Let your model find the perfect algorithms.
Whether you’re a beginner or a pro, go solo or team up (2-5 members), to create innovative solutions using any technology you love or want to try out.
How :
- Register at register.codingcontest.org (available ~3 months before the contest).
- Practice on CatCoder.
- Join our Discord for tips, updates, and community chats.
