Detective interrogating a suspect in a dimly lit room

AI-Powered Suspects

Every suspect thinks. Every suspect lies.

Our AI creates unique personalities for each character. They remember what you've asked. They have secrets to hide. The murderer will try to deceive you with carefully crafted alibis.

Ask anything. Watch for inconsistencies. Spot the lies.

Race Against Time

The clock does not stop for you.

The Daily Case gives you 12 minutes and 2 accusations. A full-length investigation gives you 40 minutes and 3. Either way, every conversation costs you time you cannot get back.

Fail to identify the killer before time runs out, and they walk free forever.

Murder evidence including knife and broken watch

Uncover The Truth

Every clue tells a story. Find them all.

Search the manor room by room. The murder weapon is hidden somewhere. A broken watch stopped at the time of death. Footprints lead to the killer's hiding spot.

9 pieces of evidence. Each one brings you closer to the truth.

Call For Backup

Stuck? Call Chief Inspector Morrison.

When the pressure mounts, you can call your boss for guidance. He'll narrow down your suspects to three. But be warned: he's not patient, and you only get one call.

In the Daily Case he is available from the very first minute. Use him wisely.

Two cases. Two worlds. One killer each.

The Daily Case alternates between the two, so the setting changes under you from one day to the next. In a full-length investigation you pick which one you want.

Blackwood Manor

A wealthy benefactor is dead in a house full of people who all had a reason to want him gone. Ten rooms, a storm outside, and nobody telling the whole truth.

Murder on the Titanic

April 14th, 1912. A first-class passenger has been murdered aboard the unsinkable ship. Eleven decks and cabins to search, and the killer cannot leave — but neither can you.

FAQ

Questions? We've got answers.

Do I need an account?
Not for the Daily Case. Today's case is playable straight away with no account, no email address and no card — you open the page and you are already investigating. An account only becomes useful afterwards, if you want your solved cases and streak kept, or if you want the longer 40-minute investigations.
Does the daily case change?
Yes. A new case goes live each day and the previous one is gone. Everyone playing on a given day gets exactly the same murder, the same suspects and the same killer, wherever they are in the world, so you can compare notes with someone else without spoiling different cases. The setting alternates between Blackwood Manor and Murder on the Titanic from one day to the next. If you start a case and have to stop, your progress is kept in your browser until that day is over.
What's the difference between the Daily Case and Premium?
The Daily Case is one short mystery per day: roughly 12 minutes, 2 accusations, no setup and no account. Premium is for people who want more than that — unlimited full-length investigations on a 40 minute clock, with your choice of setting and difficulty, 3 accusations, voice interviews and no ads. Premium does not make the Daily Case better or easier; it simply means you never have to wait until tomorrow.
What kind of game is BACKSTABBERS?
BACKSTABBERS is a text-based AI detective game. You interview suspects, search for clues, and make deductions to solve a murder mystery. Think of it as an interactive novel meets escape room, powered by artificial intelligence.
How long is each game?
The Daily Case runs on a 12 minute clock — short enough for a coffee break. A full-length investigation runs on a 40 minute clock. Either way the clock keeps running once the case begins, so set the time aside before you start.
Which mysteries can I play?
There are two settings. Blackwood Manor is a 1994 country-house murder across ten rooms. Murder on the Titanic puts you aboard the RMS Titanic in 1912, with eleven decks and cabins to search. Both are live. The Daily Case alternates between them automatically; in a full-length investigation you choose which one you want.
Do I need to download anything?
No. BACKSTABBERS runs entirely in your web browser. Works on Chrome, Firefox, Safari, and Edge. Desktop or tablet recommended for best experience.
What do I get if I do create an account?
A free account keeps your record of solved cases, and it unlocks 3 full-length 40-minute investigations where you choose the setting and the difficulty. No credit card needed. The Daily Case stays free either way, and playing it never uses up one of those 3.
Can I cancel anytime?
Yes. Cancel anytime from your account settings. You'll keep access until your billing period ends. No questions asked, no hidden fees.
