Frequently asked questions

We intend to organize a contest every month, the contest is normally held in the second half of the month, either on Saturday or Sunday. Keep an eye on our website to stay up-to-date.

The competition is open to everyone, and anyone can join and compete for our prizes.

However, due to Russia's unprovoked invasion of Ukraine in 2014/2022, we do not accept participants from Russia or Belarus.

You must have Eolymp Account to participate. If you already have one, just open contest page and click "Join".

You can join any time before contest ends.

In each Weekend Practice, you are given 2 hours to solve 5 problems. Each problem is split into sub-tasks, which represent part of the problem. The points are awarded by sub-task, meaning you have to solve an entire sub-task to get points.

The participants are ranked by the number of points they received and then, if participants have the same number of points, by the time of last productive submission.

We prepare original problems for each contest. The first few problems are normally can be solved even by a beginner, while the last few would require more advanced knowledge. Try to participate in one of the past contests to get a sense of difficulty.

We guarantee that problems are presented in English, Spanish and Ukrainian, but we try to translate problems to as many languages as possible.

Yes, all contests allow upsolve, i.e. you can continue solving problems after the contest is finished.

You can also participate in the contest virtually if you missed it.

Keep in mind, the score you receive during upsolve or virtual participation counts as unofficial and does not affect final standings.

The prizes are given to top 10 participants as well as to 10 participants randomly selected among participants ranked from 11-100.

We use random.org to choose random participants.

Please note, if you already won a T-Shirt in a given year, we will not send you another one, since it will be exactly the same.

  • If a participant from the top 10 already received a T-Shirt, we will send one more T-Shirt randomly
