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 from Starter to Case File (one to four dots): more suspects, more clue types, and deeper chains of reasoning.
