New Online Judge Platform | Reply
Hello, TopCoder!

We are glad to invite all of you to test out our new Online Judge platform at We're a Romanian based start-up that focuses on online education. Up until this point we've been working on creating a new environment for competitive programming contests.

Our first beta round took place in January and it was an IOI-style contest of medium difficulty. You can have fun solving the problems in our archive. Pay attention though, it is necessary to have an account in order to solve any problems on our website. You can connect via Facebook or Google+, or you can simply create a new account by providing a valid email address. Once you have an account you can choose a username, but all Codeforces handles are already reserved (so no tourist for the locals :D). We have created for you the possibility of connecting your Codeforces user here. Once connected, your Codeforces handle becomes available, otherwise it stays reserved for an indefinite amount of time.

Our second beta round will take place on Friday, Mar/04/2016 17:00 (UTC). If you want to take part in this round you need to register before the contest begins. Just like the previous round, the difficulty will be moderate. You will have to solve 6 problems in 2 hours and 30 minutes. This time around the format of the round will be different:

  • There will be full feedback throughout the entire contest.

  • Tasks will not have partial scoring, so you need to pass all test cases for a solution to count (ACM-ICPC-style).

  • Tasks will have dynamic score. According to the number of users that solve a problem the score will vary between 100 and 1000.

  • Besides the score, each user will also get a penalty that is going to be used as a tiebreaker. The penalty is computed taking into account the minute of the last accepted problem and the number of wrong submissions (only submissions for accepted tasks count).

More about our platform:

  • For the best user experience we recommend using Google Chrome. We are still in beta and we didn't have time to check if everything works on other browsers.

  • We currently support C++14, Java8, Python2 and Python3. We recommend using only C++ and Java for a contest, as the time limits are not calibrated for Python.

  • We have a pretty cool online editor. We use it ourselves, so give it a try ;)

  • If you find any bugs please email us at
