Hello everybody!

I hope you have the holiday spirit!

Later I will publish statistics for the year and tell you about our achievements of this year, and for now I will talk about championships and competitions that we made with our partners in 2015. My speech does not include any activities that we have conducted very far from the Codeforces site (e.g., Russian AI Cup).

This year is remembered by many interesting events that we did not by ourselves, but together with partners. I am particularly pleased that all companies who wished to fill the ranks of their employees found worthy candidates among our members. And someone said that the Olympiads are not needed! That is a lie. Here is the list of events:

VK Cup 2015

Team Championship for young participants, was conducted in Russian. 2349 registered teams of two (rarely of 1 participant). The coolest prize money and rich finals in St. Petersburg. Organizer is the VK company.

Rockethon 2015

Open individual competition by the original rules of the Rocket Fuel company. More than 3600 participants and 6565 registrations!

ZeptoLab Code Rush 2015

Individual competition by the classical rules of the ZeptoLab company. 3090 participants and 5504 registrations, excellent presents for the winners! And insanely beautiful drawings from ZeptoLab artists!

Looksery Cup 2015

! Looksery

Individual competition by the classical rules of the Looksery company. This company did not only congratulate us on our 5th anniversary, but conducted such a cool round. And the fund of the company's founder had very cool initiatives supporting the development of sports programming! 3528 participants and 5714 registrations. Yes, the gifts are yet on the way!

AIM Fund Round 2015

Individual competition in two divisions by the classical rules of the AIM Fund company. Prepared in the context of congratulating Codeforces on the 5th anniversary, thank you! 4064 participants and 6721 registrations. I've heard a lot about the after-party in Petrozavodsk. I wish I had been there!

Call To Code 2015

A competition for Irish schoolchildren by unusual rules. It was not conducted on the Codeforces site, but on our platform. Organized by the Google company.
