MurderMysteryTime — 25 Cold Case Files

Twenty-five full murder mystery cases. One free, forever.

The site you're on. Twenty-five cold case files, each one inspired by the great detective novels and by the way real unsolved investigations are actually worked: a police report, the crime scene, forensic evidence, recorded suspect interrogations and intercepted calls. Locked rooms, country-house poisonings, a body on a night train — every suspect has a motive and an alibi, and only one of them breaks under the evidence. Start with the free case: no account, no card, the complete investigation.

Mysteryic: Murder Sudoku Game

Murder mystery meets sudoku.

You rebuild the floor plan as it stood at the moment of the murder. You get a grid, a group of suspects and a list of clues. Each suspect occupies exactly one square, and no two share a row or a column. The clues give you positions — “the clerk was not by the window”, “the doctor stood directly left of the gardener”. Mark off the squares you've ruled out, and once everyone has a place only one possibility is left: the square the killer was standing on. 1,000 cases across 40 chapters, 18 languages. Completely free, and it works without an internet connection.

Interrogation Room: Murder

Question the suspects, catch them in a lie, find the culprit.

You sit across from the suspect and, each turn, choose your question from a list. Their answers go into your notebook; come back to the same subject later and say something different, and the contradiction is out in the open. You can build your evidence into the question and corner them with their own statement. But their patience runs out: push with the wrong questions and they shut down, and you start the case over. Free.

Murder OX: Mystery Puzzle Game

True or false? Mark it, and the suspects drop away.

You get a table and a handful of statements. For each one you make a single call: true (O) or false (X). Every mark closes a possibility, and every closed possibility opens the next one on its own. No long text, no files to read — pure logic. A case takes two minutes, so it plays in a queue or one-handed on the way home. Free.

Detective Grid: Clue Puzzle

Flip cards, earn clues, eliminate suspects one at a time.

In front of you is a grid of face-down cards; behind each one is a suspect and a clue about them. You start from the single revealed card and decide, based on its clue, which card to turn next — “the three on the left are innocent”, “the culprit is not in this column”. Every new card sets up your next move, and flipping the wrong one costs you a life. Nothing is told to you outside the grid — not even how many killers there are. The daily case is free in your browser, and the episode mode runs on iPhone.

Why Play These Murder Mystery Puzzle Games?

Every game on this page was built by the same two-person team behind Forgotten Mystery, and they share one rule: you can always reach the answer by reasoning, never by guessing. That makes them logic puzzles as much as murder mysteries — the kind of brain teaser where a single overlooked line in a statement collapses the whole case. If you came looking for free unsolved case files, an online detective puzzle to sharpen your deduction, or just a good true crime game to fill an evening, start with whichever card above sounds like your kind of thinking. New cases and new games get added regularly.
