The case files

Free murder-mystery logic puzzles

Every suspect sits in their own row and their own column. The clues say who was beside the bookcase, who was two squares north, who was alone — and one seat at a time the whole scene falls into place. The last person alone with the victim is your murderer. Every case is checked to be solvable by reasoning alone: no guessing, ever.

How Suspectle works

  • One person per row and one per column — the sudoku half of the puzzle.
  • Suspectle is not a weapon-and-location grid like some other daily murder-mystery puzzles. Every suspect gets a row and a column, and the one left alone with the victim is the killer.
  • Clues place people relative to the furniture, the rooms, each other, and the compass.
  • Whoever ends up alone with the victim is the murderer. Some cases hide a role to name as well.
  • Difficulty runs one to four pips: more suspects, more clue types, and deeper chains of reasoning.
