DetectiveOS vs Hunt A Killer: Browser Case or Box in the Mail?
DetectiveOS and Hunt A Killer compared: playing tonight in a browser or a box by mail, price, length, players and what each does best, checked October 2026.
In this article
Hunt A Killer made the at-home murder mystery famous: a box of evidence arrives in the mail and you spread it across the table. DetectiveOS is the same kind of investigation in your browser, with no box and no wait. Which one you'll enjoy more comes down to paper versus screen, and to what you want to do with the suspects.
We make DetectiveOS, so read this with that in mind. Everything about Hunt A Killer below comes from its own website, checked in October 2026, and prices can change. DetectiveOS isn't affiliated with Hunt A Killer; Hunt A Killer is a trademark of its owner.

What Hunt A Killer does well
Hunt A Killer is hard to beat for the feeling of a real file in your hands. Letters, photos and objects arrive in a box, and a group can spread them across a table, pass things around and argue over a physical clue. Its newest case takes 4 to 6 hours for one to six players, which makes it a proper event for a party or a long weekend. Its site offers a 30-day money-back guarantee and free US shipping over $59, with hints and reveals online if you get stuck.
What DetectiveOS does differently
DetectiveOS starts the moment you open a tab, and it holds evidence a box can't: recordings you clean up to hear what was said, phones and inboxes, a suspect's computer, a money trail. Its signature is the interrogation room, where suspects answer your question cards (ask straight, gently, press or bluff) and you catch each lie on the exact line, then prove it with the evidence that breaks it.
Each case is complete in an evening or two, with its own solution, and progress saves. When you're sure, you file charges against the killer; a wrong charge comes back to you. Sealed tip envelopes on every lead go from a gentle nudge to one that spells out the next step. And you can try a whole case free first: Speak Now, a bride stabbed before her midnight toast, with four suspects and two lies to catch.
Price
Hunt A Killer cases start at $29.99, with the newest box at $99.99, plus shipping on smaller orders. A DetectiveOS case is $7.99, or all 8 cost $35.99, and there's nothing to ship. You give up the paper in your hands; you get a case tonight, and an interrogation room a box can't do.
Who should pick which
- Pick Hunt A Killer if paper and objects on the table are the point for you, you're planning a group event of several hours, or you want a gift that arrives in a box.
- Pick DetectiveOS if you want to start tonight, spend less per case, question the suspects yourself, and investigate recordings, phones and inboxes as well as documents.
- Not sure? Play the free DetectiveOS case first. It costs nothing and takes about an hour.
