Hi Folks!
The CF Blitz tournament on Codeforces is usually limited to top coders. I've always found that format insanely exciting — fast problems, pure pressure, and that race-to-AC feeling.
I really wanted to experience that kind of 1v1 intensity more often, not just once in a while. So I built CF Blitz — a simple place where anyone can jump in and feel that same blitz energy anytime.
What is CF Blitz?
A minimalist platform for real-time 1v1 competitive programming using Codeforces problems.
No clutter. Just you, your opponent, and the clock.
Key Features
Seamless Login — Sign in instantly with Google and link your Codeforces handle.
Ranked Matchmaking (Random Game) — Jump into queue and face someone near your skill level. Win matches. Gain CF Blitz Rating.
Challenge a Friend (Custom Game) — Create a private lobby, configure duration and problem difficulty, and share a join code.
Why This Works
Blitzing pushes you into flow state. There's no room for procrastination, no time to overanalyze every edge case for 20 minutes. You trust your first instinct and execute.
Head-to-head competition turns practice into a game — and games are addictive. You get faster. You get sharper. You get more confident.
