The Qualification round has started! Cheer for your favourite team: https://ranker.codeforces.com/ranklist/602915
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.

Я в шоке, TOURIST будет задачи составлять. Это будет офигенный контест
посмотри его предыдущие контесты, там есть нехорошие моменты
Thanks for reviving the craziest and the most fun programming competition format!
Thank you! Would be awesome to have you there =)
Could you please provide more details?
Thanks!
Hey — sure!
2 -> So if we pass to the final, trip and hotel are paid by ourselves?
We aim to cover as many of the trip expenses for the finalists as possible — ideally, all of them.
Dumbs like me eligible or not?
Small brain doesn't imply dumbness you know ;-)
As long as you're weird enough...
Is this round rated??
No, it will not affect your CF rating
Hoping for some really interesting problems, especially from the 8th problem setter!
Solo/Individual participation not applicable ?
You can register to participate solo, although we do recommend to find a team. Registration is now open: https://midnightcodecup.com
age limit why
(Not an organizing committee but I've seen many high-school-friendly events running)
It requires considerable additional paperwork/organization effort to make it possible.
Secondly, for this event, 1 kid in the room full of adults on the finals would not be great idea. We don't want you to have a bad time.
Competing for qualifications just for fun should be fine (in my personal view).
How many gets qualified for the finals?
25 top teams will qualify + up to 5 wildcards. If any of the qualifying teams can't come to the finals, we'll invite the 26th-ranking team and so forth.
Registration is now open: https://midnightcodecup.com
By this, do the teams need to have exactly three participants? Would we be able to compete as individuals or teams of two?
You can register solo or in a team of 2. Registration is now open: https://midnightcodecup.com
What is the format of the qualification round? Will it be like an ICPC contest?
Most problems will be not in ICPC-style but in marathon-style instead: you will get a score instead of WA/AC. Also, most of the problems will be in the "local" format as Google Hash Code: you will need to produce an output on your machine and submit it instead of the code.
Looking for team. I'm decent at heuristics and stuff
(Edit) I found one
Looking for a team. Found the team!
When will the registration open?
It's open! https://midnightcodecup.com
What's the deadline for the registration?
It's best to register before April, 5th
will there be some kind of legit certification for competing?
What do you mean by legit certification? CF rating will not be affected
Also will the problems be like the regular CF contests or we should expect something different
Definitely expect something different =)
“ No programming language, affiliation or problem solving methods restrictions.”
Does this allow the use of AI?
Yes!
can you please double confirm this because the registration page asked to follow rules as per Mike's blog on AI usage
A bit unrelated but it's great to see people like Gassa still doing CP related stuff.
Hi, can I check whether it is possible to add teammates? Is it okay if I resubmit the form again with the new teammates? Thanks!
Is it possible to extend registration deadline?
How many problems are there?
The contest is just 2 days left, so please provide more information!
I missed the third update that says the registration closes on April, 9th. So my team and I missed the opportunity to register :( Why close the registration two days before the contest date?
Contact [email protected], might be still possible
Thank you
Is it allowed to use 3 PCs at the same time? If yes, what about cloud computing?
i cant access the contest link page when i login my cf account on link page and it show access denied . It notify me you cant view this page while you are not group member. how i can fix this issue please help me
You need to login with the team credentials that were sent to your email, not with your standard cf account.
Is it possible to add another member in my team as of now?
Do I need to submit a source code and the answer during the contest?
Мы с командой из Sorbonne University получили письмо с подтверждением регистрации, но данные для входа так и не пришли. Уже писали на [email protected], но ответа пока нет.
My team and I from SorbonneUniversity received the registration confirmation, but the login credentials still haven’t arrived. We’ve already written to [email protected], but haven’t heard back yet.
WHERE DO WE GET CONTEST LINK
You should have received the link and the credentials by email.
I am getting access denied when I try to login. It says "You can't view this page, you are not a group member"
Please log out of your regular Codeforces account (press Logout in the top right corner of the page) and try again.
Worked!!!. Thank You so much
AI was able to solve problem C1. I gave the assembly program to Gemini 2.5 Pro Preview 03-25 (you can try this model here) and it found the correct formula.
