The concept

Thriller experience crafted for you

Leave the boxed mystery games on the shelf. This is the first investigation that comes looking for you in your real life, and this time the main character is you. Someone knows your name and your address. For four weeks you run the case, and you try to survive it. Your case is one of a kind, built around your own details: you don’t follow the plot, you are part of it. Our players all say the same thing: at some point, you forget it’s a game.

REAL
not fiction

A true crime series you don’t watch, you live: fake websites, real letters, phone calls, photos, videos. You’ll forget it’s a game.

100%

We create content specific to each player for a fully immersive experience. You are truly part of the story.

4+
weeks

A minimum of four weeks at your own pace: the investigation adapts to your personal life and your job, and comes to you wherever you are.

“It's absolutely amazing. EXTREMELY worth the $60. They set up real social media pages, fake FBI websites, Google Maps, photos, videos and actual snail mail… plus all these puzzles to solve.”

“It feels real. I love it. Once you get involved, you feel like you're in too deep and can't get out, but I never want it to end. Best fun I've had in years. It feels like I'm investigating a real case.”

“I’ve been playing this for about a week now. It took me a minute to understand how to figure out the clues but once I did, it’s been fun. Challenging, but not so challenging that it’s impossible.”

“Incredible game so far. I’m hoping the next will be harder but I’m only a week in, maybe it gets harder. The daily puzzle takes me about 15 minutes, then I’m just waiting for the next one.”

Why it’s like nothing else

Step into a real investigation

You communicate directly with the key figures in the case, through channels that change as the investigation unfolds: calls, messages, letters, documents.

An entire cast of characters comes to life, each with their own personality, secrets and intentions. To make it as realistic as possible we built our own story engine, designed to adapt to your answers and to the way you investigate.

It is up to you to ask the right questions, sometimes adopt a false identity, and choose your words carefully to move the investigation forward.

As you progress the case gets more complex. Certainties fade, tension rises, and every detail can change everything.

The verdict

More case. For less.

More hours, more story, more reality, for a fraction of an escape room or a monthly mystery box.

Good to know

Frequently asked

What exactly is this Experience?

It's the first ultra-realistic investigation experience that takes control of your real life for at least four weeks. Less a game you play, more a case you actually live.

What if I need more than 4 weeks?

Take as long as you want. Four weeks is the pace most players settle into, not a deadline. Nothing in the case runs on a clock: it waits at every step, so you can pause for a week, take a vacation, and pick it back up exactly where you left off.

How much does it cost?

$59, once. No subscription, no add-ons, nothing else to buy. That covers the four weeks, everything that reaches you and lifetime access to your case.

How does it start?

It's simple: you purchase the experience, you fill out a confidential questionnaire (like in the movie The Game), and you choose when to begin the investigation. From there, the story gradually unfolds and becomes part of your real life.

Is this giftable?

Yes, and the gift option is free. Your access code arrives by email with a gift option inside: generate a personalized printable certificate with their name and their code, or let us reach them with an ultra-real first message and photos of their own street, then the reveal. You choose when.

How will I receive clues?

Through text messages and WhatsApp, phone calls, emails, physical mail, documents to analyze, photos, videos and audio files.

Does the story adapt to my choices?

Absolutely! Every decision you make shapes how the story plays out. No two players ever live the same story.

Does the investigation move forward without me?

No! The game never advances without you. It waits for you at every step.

Can I play with a group of friends or family?

The experience is fully personalized for one player: only the registered player receives all messages, emails and clues, and only they can interact with the game characters. Couples sharing one copy works well, but larger groups should each purchase their own.

Is it scary?

It's a realistic thriller, so yes! Some moments can be intense, unsettling, or make you feel uneasy.

But it stays in your mailbox, your phone and your screen. Nobody will ever follow you in the street, ring at your door or show up in person. No actor, no jump scare in real life. You are never in any danger, and you can stop or pause whenever you want.

Can I play from my country?

The experience is currently built for players in the United States: the physical mail, the calls and the timing are all tuned for U.S. addresses and hours. All you need is an address, a phone and internet.

What language is it in?

English. The calls, the messages, the documents and the physical mail are all in English, so you need to be comfortable reading and replying in it.

Do I need any special equipment?

No, just: a mailing address to receive letters, a smartphone, and internet access.

Nothing to buy, nothing to install, no printer needed. Everything reaches you through your usual email, your phone and your letterbox.

Is there an age limit?

Yes, 18 and over. It is horror fiction and it deals with a cult, disappearances and simulated violence.

Do I have to give my real details?

Only your address, so the mail can reach you. For the rest, if you would rather invent something, invent it. Another first name, a job you never had, a memory that never happened: the investigation works with whatever you give it.

What if I would rather not receive mail at home?

Tell us before your case starts and we run it without the physical mail. Everything comes through your phone, your inbox and your screen instead.
