Forgotten Mystery: Murder Case
Murder mystery game · Detective game · Cold case files
Solve cold case files on the site you are on right now.
You are handed a cold case file and given everything inside it: the police report, the crime scene examination, forensic results, bank records, camera timestamps and the interrogation transcripts of every suspect. You move between the tabs and hold statements against evidence, because one suspect gets the time wrong and another knows a detail they were never told. When you are ready you name the killer, and the game walks you through the full solution. The first case is free in your browser, no account needed. The app carries two free cases and plays offline.

Cold Case Online
Murder mystery game · Online party game · Cold case files
Open the police file and solve it, alone or with friends.
Every case is a box of original-style police documents: statements, phone records, receipts and scene photos, with nothing highlighted and nothing in order. Read it alone, or create a room and invite friends to work the same file together from their own phones. When the group agrees, you name the killer. The first case is free.

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.
Free · iPhone & 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 the evidence into your question and corner them with their own words. But their patience runs out: push with the wrong questions and they shut down, and you start the case over.

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. A grid, a group of suspects, 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. Cross off what you have ruled out, and when everyone has a place only one square is left, the one the killer was standing on. A thousand cases across forty chapters, eighteen languages, free and fully offline.

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, and 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.

Logic puzzle · True or false mystery game

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.

Questions About Our Free Detective Games
Are these murder mystery games really free?
Yes. Every game on this page is free to start and most are free from beginning to end. Forgotten Mystery gives you the first case free in your browser and two free cases in the app. Mysteryic, Detective Grid, Interrogation Room, Murder OX and Braino are free to play. We never ask for a card before you have played.
Can I play these detective games offline?
The phone versions work without a connection. Forgotten Mystery, Mysteryic and Braino all keep running on a plane or underground, because the cases and puzzles live on the device. The browser versions need an internet connection to load, but nothing is streamed while you play.
Do I need to download anything to play in my browser?
No. Forgotten Mystery, Mysteryic, Detective Grid and Murder OX all run in a normal browser tab with no download and no sign-up. Open the page and the case starts.
Can these be played as party games with friends?
Yes. Liary and Truth or Dare Party Night are made for groups: one phone goes around the table and everyone plays. Pairo is a question card game for couples and friends. The detective games work as a group too: read the case file out loud, let everyone defend a different suspect and accuse together.
Are the puzzles solvable by logic, or do I have to guess?
Every case has one answer you can reach by reasoning alone. The contradiction is always somewhere in the evidence you have been given. If you have to guess, we consider that a mistake in the puzzle, not in the player.
Which game should I start with?
If you want a full case file to read and pick apart, start with Forgotten Mystery. If you would rather have a short logic puzzle, try Murder OX or Mysteryic. Braino is the one to pick when you want a hundred word and board puzzles with no story at all.
