Hello, this is 79brue.

I’m excited to announce that BCF 2025—a project I began planning in January 2024—is finally complete.

All of the contest problems were written by me, including a special-format extra problem.

The contest will be held on BOJ (Baekjoon Online Judge). If you are new to this online judge, here's a helpful guide on how to get started.

The contest will take place from August 16, 11:01 to August 17, 11:01 (UTC+9).

We have prepared prizes totaling approximately ₩400,000 (~$290), including rank prizes, special prizes, raffle prizes, and solved.ac badges and backgrounds.

For more details, please refer to the Contest Overview tab.

I hope many of you will join and enjoy the contest. Thank you!
