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 secrets, 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.

Cold Crime: Murder Mystery

Murder mystery game · Detective game · Cold case investigation
A murder mystery game played on the victim's phone.

The victim's phone is unlocked and in your hands. Read the messages, scroll the call log, open the photos and go through the notes, then answer the case file questions to prove who did it and how. Some albums stay locked until you find the passcode hidden in the evidence. A detective game and a cold case investigation in one: nothing gory on screen, just evidence, contradictions and the moment the whole story clicks.

Interrogation Room: Murder app icon
Free · iOS & Android

Interrogation Room: Murder

Detective game · Interrogation game · Murder mystery
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.

Mysteryic: Murder Sudoku Game app icon
Free · iOS, Android & Web

Mysteryic: Murder Sudoku Game

Murder sudoku · Logic puzzle · Deduction 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.

Detective Grid: Clue Puzzle app icon
Free · iOS, Android & Web

Detective Grid: Clue Puzzle

Deduction game · Board-style clue puzzle · Detective game
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.

Murder OX: Mystery Puzzle Game app icon
Free · iOS, Android & Web

Murder OX: Mystery Puzzle Game

Logic puzzle · True or false mystery 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.

Free to start · iPhone & Android

Liary: Party Games & Imposter

Party game · Imposter game · Word game for groups
An imposter party game for friends, played on one phone.

Pass one phone around the table. Everyone sees the secret word except the imposter, who has to bluff their way through. Give a one-word clue, listen to the others and vote out the liar before they work out the word. Liary puts several party games in one app, imposter, charades and other word and drawing games, so game night, a road trip or a family gathering needs nothing but a single phone.

Truth or Dare Party Night app icon
Free to start · iPhone & Android

Truth or Dare Party Night

Party game · Truth or dare · Group game
The classic truth or dare party game, on your phone.

Add the players, pick a deck and let the phone decide who goes next. Answer the truth honestly or take the dare, from light icebreakers for friends and family to bolder rounds for couples and adult party nights. No cards to shuffle and no arguing about whose turn it is. Good for sleepovers, birthdays and any night that needs a warm-up.

Pairo: Questions & Card Games app icon
Free to start · iPhone & Android

Pairo: Questions & Card Games

Couples game · Card game · Deep conversation questions
A couples card game full of questions worth answering.

Pick a category, from first-date icebreakers to deep conversation questions, would you rather and relationship talks, and take turns drawing a card. New couples use it to get to know each other, long-term partners use it for a better date night than scrolling side by side, and it works just as well as a question game for friends.

Braino: Word Board Logic Games

Board games · Word games · Logic puzzles
A hundred puzzles in one app, with no ads and no internet.

Not a murder case this time, just thinking for its own sake.

Everything runs on the device, so it works on a plane or underground with no connection at all, and no advertisement interrupts a puzzle. Pick a game from the shelf, play it as long as you like and move on to the next one.

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.
