Participation

Teams of up to five people are allowed to participate.

The qualification stage is fully online. Teams which have members who are not high school students are only allowed to participate in the unofficial standings. However, all scores, both official and unofficial, will be uploaded to CTFtime.

You can sign up until the end of the qualification stage. When you open the challenge board for the first time, you’ll no longer be able to add or remove team members.

Prohibitions

During the game, it is prohibited to:

Attack the infrastucture

Publish or share the challenges

Share flags with other teams

Format

The duration of the competition is 36 hours. We may extend this time to compensate for unexpected circumstances, should they happen.

Participants get the challenges (also called tasks). The final answer for a challenge is called a flag: it is a string that matches the regular expression ugra[A-Za-z0-9_]{2,} — for example, ugra_ex4mpl3.

Challenges are published in the challenge board which can be accessed by logging in as a team.

Submitting a flag increases the team’s score by the cost of the challenge. The team with the biggest score wins. Among the teams that have the same score, the team whose last successful submission happened earlier wins.

After the game

When the game ends, the results will be announced, and the writeups for the challenges will be published. Electronic participation certificates will be available when the scores are finalized.

Members of best teams of the official standings will be invited to participate in the finals on April 12. We intend to conduct the finals on-site in several venues across Russia, but it might change. Follow the announcements.

Participants who score best in the finals will get valuable prizes.
