We’re excited to launch the first-ever Midnight Code Cup (MCC) — a team competition featuring an online Qualification round and a 24-hour onsite Final. Expect algorithmic challenges, optimization puzzles, cutting-edge computer science, and some just plain weird problems. It’ll be exhausting. And fun.

Who are we?

A team of problem solving geeks veterans enthusiasts, eager for the return of this contest format. The idea of Midnight Code Cup was born at Recraft.AI (AI image generation and graphic design pioneers) with huge support from JetBrains (creator of Kotlin, intelligent IDEs, and AI-driven developer tools) as well as Neon (developer-first open-source database) and Pinely (HFT company powered by competitive programmers).The sponsor list is not final and will be updated.

We are also thankful to have Codeforces as our hosting partner.

Who can participate?

Teams of 3 ready to rock and roll! No programming language, affiliation or problem solving methods restrictions. You only need to be at least 18 years old and have a slightly concerning enthusiasm for coding challenges.
