In 2021 (as in 2019 and 2020), with the support of XTX Markets, 6 rounds of the new Codeforces Global Rounds are held: common rounds for both divisions of 7–9 problems each. The duration of the rounds is 2-3 hours, depending on the number and complexity of the problems. All such rounds are rated for all participants. At each such round, 50 brand T-shirts are handed out, and we are happy to give T-shirts to all problem authors.
The prizes for the 6-round series in 2021:
- In each round top-100 participants get points according to the table.
- The final result for each participant is equal to the sum of points he gets in the five rounds he placed the highest.
- The best 20 participants over all series get sweatshirts and place certificates.
Current standings after five rounds (sorted by total points in four best placed rounds):
