Murder Mystery Puzzles for Adults — Printable Case Files, Picture Puzzles and Daily Games
The best kinds of murder mystery puzzles for grown-ups — elimination case files, picture puzzles, multi-puzzle mysteries and a free daily whodunit — with what each one is like to play and how long it takes.
- Elimination case files: hundreds of records, about a dozen clues, one survivor — 2–4 hours.
- Picture puzzles: the records are drawings you read closely; works in black and white.
- Multi-puzzle mysteries: a main elimination plus a cipher, logic grid or lock — 3–5 hours.
- Daily murder sudoku: a 5–20 minute floor-plan whodunit, free every day.
- Look for checkpoints after every clue and exactly one answer — the signs of a fair puzzle.
Murder mystery puzzles have quietly become one of the most popular "evening in" activities for adults: no party to organise, no roles to read aloud, just a case, a pencil and a satisfying final deduction. They come in a few distinct styles — here's what each one is like, so you can pick the right one for your night.
Elimination case files
The classic format. A story sets up the crime; then you get a big record book — a cloakroom ledger, a carnival's ride log, a visitors' book — with hundreds of entries, and about a dozen clues. Each clue removes some of the records ("the killer's coat had a fur collar", "they arrived after 9 pm") until exactly one is left.
- Time: 2–4 hours
- Best for: a long, quiet evening; people who enjoy spreadsheets and crosswords
- Look for: a checkpoint table ("after clue 3: 412 left") so one slip doesn't ruin the night
The Cloakroom Killer
Christmas Eve 1929: 800 coats, 12 clues and one killer. A logic-elimination puzzle for a cosy evening.

Same elimination idea, but the records are drawings: Polaroids of costumed skaters, pies on a contest table, finish-line photos of skiers. Instead of reading a table you read pictures — the hat, the collar, what someone is carrying. It feels more like real detective work and is lovely to look at.
- Time: 2–4 hours
- Best for: visual thinkers, couples, anyone who finds big tables tiring
- Look for: clues about shapes, not colours, so it prints well in black and white
The Costume Contest Killer
Halloween 1986 at a roller rink: find the killer on a wall of 360 drawn Polaroids.

The main elimination answers who; extra puzzles answer where, when and why. A séance case might add a seating plan, a symbol cipher, a combination lock and a word search; a wedding case a logic grid, a spot-the-difference and a nonogram.
- Time: 3–5 hours, easy to split over two evenings
- Best for: groups where everyone likes a different kind of puzzle
The Midnight Séance Murder

Some cases are built as several connected investigations — security photos, a switchboard log, sealed cabinets and a crossword — each producing one piece of the answer. Great for a team that wants to divide the work.
The Night Ward Killer
A 1981 hospital night shift: security Polaroids, a switchboard log and a crossword, four investigations in one case.
1–4 solvers

What is a murder mystery puzzle for adults?
A self-contained detective puzzle you solve alone or with friends, without a host or actors. You get a story, evidence and clues, and the solution follows by logic — usually one killer among many suspects or records.
Can you play printable murder mystery puzzles alone?
Yes. Case files and murder sudoku puzzles are designed for one to four solvers. Many people play solo over an evening, or split the clues between two people as a date night.
Do printable case files work on a tablet?
Yes. They are PDFs, so you can solve on a tablet with a note-taking app, or print only the pages you want. A black-and-white printer is enough when every clue is a shape rather than a colour.
How do I know a murder mystery puzzle is fair?
Fair puzzles have exactly one answer reachable by logic, say so clearly, and give you a way to check progress — for example the number of suspects that should be left after each clue — plus hints that don't spoil the ending.
