Hello, Codeforces! We, Algolymp, are a team of competitive programmers from Romania, and we’ve been working on Codeforge, a multiplayer game built around solving algorithmic problems. Special thanks to munteanuvlad98 for coordinating this project.

The idea is simple: take the problem-solving we enjoy and give it more ways to be played together. Challenge a friend, compete as a team, enter a knockout tournament, or work through daily problems on your own.

What can you do in Codeforge?

• Solve daily challenges. Problems range from beginner-friendly exercises to IOI/ICPC-level challenges, whether you’re learning your first algorithms or preparing for your next contest.

• Play individual or team battles. Go head-to-head with another player, or team up with friends and compete against another team.

• Enter knockout tournaments. Compete individually or as a team, with each round deciding who advances.

• Build a community. Bring together your school, programming club, or friends to train and compete.

• Earn Algocoins. Spend them on merchandise, video games, or in-game items that can help you in battles.

• Create your own competitions. Organize an algorithmic contest for your community or challenge a group of friends.

What about cheating? A close battle isn’t much fun if you can’t trust the result. Codeforge includes an AI-powered anti-cheating system designed to detect unfair play and help keep progress and competitions fair.

Help us make it better Whether you’re a beginner or an experienced contestant, we’d love to have you try Codeforge. Tell us which formats you enjoy, what feels off, and what you’d like to see added.
