Your Scenario

Your stories come to life, one choice at a time

A free detective mystery game, played online

Run the case like a real detective: a crime scene, suspects, clues — and a culprit fixed in advance that the AI will not change along the way. You ask the questions, you cross-check the alibis, you make the accusation.

A free online detective game, nothing to install

This is not a fixed text to read: it is an interactive investigation where you decide every step. Question a witness, search a room, confront a suspect — follow one of the suggested leads or type your own move, and the story advances on your decisions.

The culprit never moves. Every case is fully built before your first question — victim, suspects, motives, alibis, clues — and the AI sticks to it to the end. You investigate against a real solution, not against a story improvised as it goes.

Start for free, without signing up, right in your browser, at your own pace.

How it works

1. Pick your case: today's case, or one from the catalogue.

2. Investigate chapter by chapter: interrogate the suspects, examine the scene, cross-check the testimonies. Your case file fills up as you go — suspect sheets, clues, loose ends.

3. Accuse: when you are sure, name the culprit. You only get one accusation — instant verdict, a score out of 100, then the full reveal of what really happened.

A new murder mystery every day

Every day a brand-new case goes live: the daily mystery. A setting, a victim, suspects who all have something to hide — and the pleasure of being among the first to solve it.

Past cases join the catalogue: play them whenever you want, and compare yourself with other players — how many detectives tried the case, how many found the culprit.

The suspect sheet: your key tool

A suspect sheet gathers everything you know about someone involved in the case: their identity, their link to the victim, the motive they could be given, their alibi for the time of the crime, and the grey areas that still do not add up. It is the document every detective keeps at hand — here, your case file keeps those sheets up to date automatically as the interrogations unfold.

One example: the victim's niece, heir to a third of the estate — there is the motive. She claims she stayed in the library from 9 pm to midnight — there is the alibi. But the butler did not see her there before 10:30 pm: there is the grey area.

The sheet is never final. Confront the suspect with that missing hour: she backtracks, invents or breaks — and her sheet changes, often dragging another suspect's sheet with it. One contradiction resolved opens another: that is exactly what drives the investigation to the final accusation.

Three recent cases to play

Straight from the catalogue — a new case is published every day and joins the list.

The Boardroom Buyback

Polished concrete floors mirror the cold, amber glow of expensive whisky decanters, while the air hangs thick with the bitter taste of a shared dream soured by ambition and secret ledgers.

The Chiltern Porcelain Affair

A fog-choked autumn evening at Chiltern Manor. The library and long gallery host the final, tense viewing of the legendary Hartington porcelain collection. Beneath the veneer of sherry and polite murmurs, financial ruin and bitter grudges simmer among the assembled dealers, collectors, and the widowed Lady Hartington.

The Last Pint

A converted mill deep in the Pennine hills, where polished copper vats and oak barrels stand silent witness. The sweet scent of malt hangs in the air, now soured by the acrimony of a shared dream curdling over money and control.

Frequently asked questions

Is the detective game really free?

Yes. You can start a case for free; complimentary credits let you discover the game before any subscription.

Do I need to sign up to play?

No, you can open a case without an account. An account only serves to find your ongoing cases again later.

Can I interrogate the suspects freely?

Yes. You ask your own questions and run the interrogation as you see fit; each suspect has their own personality, answers and grey areas.

Is it always the same mystery?

No. A new case is published every day, then joins the catalogue. Each case has its own solution — culprit, motive, alibis — fixed once and for all when it is created: the AI does not improvise it mid-game.

How does a case end?

With your accusation. You only get one: name a suspect when you are convinced. The verdict is immediate, with a score out of 100, then the reveal shows you what really happened — and what you missed.

Can the AI change the culprit along the way?

No. The entire solution is generated and locked server-side before you play. Whatever you try, the facts of the case stay consistent from the first question to the reveal.
