About Everybody Codes
The puzzles train algorithmic thinking and careful reading. It suits programmers who already know one language well. There are also smaller "Stories" events, and past events stay open to play.
You need an account to get input notes. There is no penalty for a wrong answer, only a short wait. If you use AI, you are asked to mark your profile so it goes on a separate leaderboard.
