Round will be rated for participants with rating less than 2100. Participants from the first division are also welcomed to take part out of competition.

You will be given 2 hours to solve 6 problems, each problem has a picture and a story above it. The stories are skippable if you want to focus on the real problems.

We would also like to thank:
