01How it worksSelf-paced · 1 attempt

Code Cracker is a puzzle game built for the short window between meetings. The round is self-paced, with 1 attempt before the score locks. Logic, lattices, the satisfying click of a solve. The team-wide leaderboard rebuilds itself daily, so the only thing carrying from yesterday is bragging rights.

  1. 01
    Goal
    Crack the secret 4-color code in as few guesses as possible.
  2. 02
    How it works
    Pick 4 colours and submit your guess. The clues tell you how many are in the right spot (right colour, right position) and how many are right colours but wrong spots.
  3. 03
    Colors can repeat
    The secret code may contain duplicate colors, making it trickier!
  4. 04
    Fair play
    Everyone gets the same code, so it's a fair contest of deduction.
