The Treacherous

Unite for thrilling missions, banish the treacherous at the relentless round table, and survive the night!

Can you outwit the killers in this ultimate game of deception?

You are invited to a 'The Treacherous' immersive gameplay experience inspired by our historic courthouse. The concept is simple, but the game is dangerous.

The Game

• Your Secret Role: Upon arrival, you will be summoned to the Judge's Chambers for a private interview and assigned a secret role.
• The Challenges: Throughout the evening you will work together (or sabotage each other) in 3 high-energy missions.
• The Banishment: After each mission, the group will gather at the round table to vote. Who is acting suspicious? Who is lying to your face? And who do you want banished?
• The Murder: When the blindfolds are donned, the treacherous awake to choose their victim. But who do they want gone?

Your Evening Includes

• One Unforgettable Setting: Step behind the impressive façade of the historic Sessions House and experience The Courtroom, the stately Magistrate's Room transformed like never before.
• The Full Transformation: Don your own hooded cloak and immerse yourself in the role. We provide all costumes, game props, and mission materials.
• The Jurors’ Bar: Our fully stocked bar will be open throughout the evening. Whether you need a glass of wine to celebrate an exile or liquid courage to hide your guilt, we will keep your glass full.
• The Post-Trial Social: The game doesn't end if you're exiled! Stick around for our social mixer—the perfect chance to debrief, reveal your strategies, and laugh with the friends you just betrayed.

What's a Spectator Ticket:

Want to soak up the atmosphere without the pressure of the gameplay?

If your friend, partner or family are playing, why not join us as a Spectator. You will be welcomed into the fold with your own cloak upon arrival, allowing you to fully immerse yourself in the scene. From the vantage point of the historic Public Gallery, you will have a bird's-eye view of every accusation, every betrayal, and every banishment.

You are free to capture photos of the drama as it unfolds, but remember: you are a silent observer. While you may root for your friends and family from above, you must not influence the game.

Trust no one. Suspect everyone.
