Mystery Nights by Mastermind

Sixty strangers walk in.
One is the killer.

Live social deduction events for bars, restaurants, breweries, and private venues. A trained GM runs the night. Your guests do the rest.

Book a Mystery Night See How It Works

Mystery Nights are fully hosted live-play events — we arrive with everything: props, clues, AI-powered suspects your guests can interrogate from their phones, and a game master who runs the night from start to finish. No trivia nights. No murder mystery dinner theater scripts. It's a rotating line of themed nights — Lovecraft, Sherlock, Prohibition gangsters, a gilded inheritance, and more on the way — so you can pick the one that fits your room and rebook a different mystery next season.

How It Works

01

Book your night

Fill out the inquiry form below. We'll confirm availability, talk through your venue requirements, and lock in a date. Packages start at $200.

02

We show up ready

Our game master arrives 1–2 hours early to set up props, clue sets, and the digital infrastructure. Your staff runs your bar. We run the game.

03

Your guests become suspects

Every guest gets a role. Investigators question AI-powered NPCs from their phones, find physical clues around the room, and race to name the killer before the clock runs out.

Battleship Cove, Fall River MA

Battleship Cove

Fall River, MA

We ran Eldritch Mystery & Madness aboard the USS Massachusetts with over forty players navigating the ship's corridors in search of the cult leader. The venue became part of the game.

We partner with venues that want to offer something their guests have never experienced — and we handle everything so they don't have to.
