Mystery desk

Fictional house files, real public records, and hidden signal trails

The fun track gives the community puzzles to solve together. The civic track keeps real-world cases source-bound, respectful, and no-score.

Why the hidden board exists

The signal-hunter leaderboard is public so new users can see that there are hidden rooms, coded phrases, and agent stories waiting outside the main case feed.
