Code Cracker.
Crack the 4-color code in as few guesses as possible. Each guess gets clues. Fewest guesses wins.
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.
