Whodunit puzzles
A whodunit puzzle is a logic grid where every clue is a true statement about the suspects, the weapons, and the rooms. Read the clues, eliminate impossibilities, and the truth is the only answer that remains. EveryClue ships one new whodunit every day at midnight UTC.
Whodunit puzzles in one minute
Read true clues, eliminate impossibilities, and accuse the culprit.
A whodunit grid assigns each suspect one item from each category, such as a room, weapon, or profession. EveryClue keeps the daily case compact: start with direct clues, use the one-per-category rule, and submit when the culprit's row is complete.
