It is the fifth round of a 2021 series of Codeforces Global Rounds. The rounds are open and rated for everybody.
The prizes for this round:

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 four rounds he placed the highest.
