Hi Codeforces,

Have you already spotted it in the schedule? Yes, the next Global Round is coming up on Sep/20/2025 17:35 (Moscow time)!

I'm excited to announce a series of three Global Rounds that we'll be holding in 2025. As always, these rounds are kindly supported by XTX Markets. Huge algorithmic thanks to them!

Each Global Round will be a common round for both divisions, featuring 7–9 problems. The contest length will be 2–3 hours, depending on the number and complexity of the problems. All rounds are rated for everyone. At each round, 50 branded T-shirts will be awarded, and of course, all problem authors will receive T-shirts too.

Prizes for this round:

• Top 30 participants will get a T-shirt.
• Another 20 T-shirts will be randomly given out among participants ranked from 31 to 500 (inclusive).

Prizes for the 3-round series in 2025:

• In each round, the top 100 participants will earn points according to the scoring table.
• A participant's final score will be the sum of points from their two best rounds.
• The top 20 overall will receive sweatshirts and certificates.

Wishing you a fun and memorable experience in the Global Rounds!
