Think you know who to trust?
A room of innocents, a few hidden traitors, and the vote that decides it.
Everyone gets a secret role. Most of the room is loyal; a few are traitors. At night the traitors pick someone off. By day the room argues, accuses and votes. If the traitors are still standing at the end, they win. Treachery! (aka Mafia, if you've played it at a party) is our take on the classic game, adapted to your event and hosted by someone whose job is to keep the drama high and the mood kind.
Treachery! comes to you: any room with chairs, no set, about 50 minutes a session, and it repeats through a day for a bigger group. London-based, we come to your office or venue; travel outside London is extra. It has run at Camp Wildfire every summer since 2024, in festival sessions of up to 200 players.
Treachery! is all about fun, laughter, outrageous accusations and deduction, and getting everyone involved, while making sure everyone's friends at the end.
How it works
Loyal or traitor?
Join the game
Participants are assigned secret identities… some are loyal attendees, while a few are undercover traitors. This creates an engaging dynamic where trust and suspicion can shift rapidly.The drama unfolds
In each round, the traitors secretly "eliminate" loyal players. As the tension rises, the remaining participants engage in heated debates and discussions, attempting to identify the traitors among them.Secret roles for added fun
To enhance the experience, some players receive special abilities. For instance, the Negotiator can save a fellow attendee from elimination, and the Chairperson casts deciding votes, introducing strategic elements that complicate alliances and betrayals.Facilitated action
The game is hosted by an enthusiastic facilitator who ensures a lively atmosphere. With storytelling, upbeat music and interactive moments, participants stay engaged and energised throughout the event.The final showdown
As the player count dwindles, participants must decide whether to trust each other or continue hunting for potential traitors. If the traitors manage to stay hidden until the end, they clinch victory. However, if the loyal attendees successfully expose them, the win is theirs!
What's included
One host, one session, everything to run it.
- A Get Social host who runs the whole session: the rules, the pace and the drama.
- A secret role for every player, with the special roles (the Negotiator, the Chairperson) dealt in.
- The storytelling, the music and the running order, so nobody on your team has to host.
- A session for up to 30 players, about 50 minutes, repeated through the day for a bigger group.
- The reveal at the end: who the traitors were, and who should never have been trusted.
The room you need
Indoors, chairs, and nothing to climb.
- Chairs for everyone, in a circle or a horseshoe: a meeting room, a function room, a conference hall or a marquee.
- Mental, not physical: no running, no tasks on the floor, and every ability plays on equal terms.
- No screen, no set, no rig. A microphone is useful for 30 but isn't essential; we bring the rest.
- A room you can hear each other in: the arguing is the game.
Who it's for
Team building, Christmas parties, conferences and more.
- Team building and away days: a room that has to talk, listen and read each other, with nobody left at the edge.
- Christmas parties: the office party game that puts the whole team in one story, before or after dinner.
- Conferences: an icebreaker for 30, or back-to-back sessions through the day for a hall of 150.
- Festivals: Camp Wildfire has run it every summer since 2024, in sessions of up to 200 players.
- Freshers' Week and student societies: a room of strangers into a room of friends in an hour.
- Charity fundraisers: a game the whole room plays, with the accusations as the entertainment.
Christmas parties
A Traitors-style Christmas party.
The office party with a plot: a session of Treachery! before dinner, or after it, with the whole team in one story and the traitors at your table. From £20 a person with a minimum of £600 a session; a session takes up to 30, so a company of 60 is two sessions back to back. We come to your venue, any room with chairs.
Add-on
Add tasks between rounds.
Want missions as well as murders? Tasks between rounds are an optional add-on to a Treachery! session: short challenges the whole room takes on together, in the Traitors style, between the night and the vote. Tell us your group size and the time you have, and we'll put a price on it.
Case study
Treachery! at Camp Wildfire.
At Camp Wildfire 2024, Treachery! quickly became a standout activity, perfectly complementing the festival's spirit of adventure, creativity and community.
The game's blend of mystery, strategy and fun was the perfect complement to the more physical parts of the festival (quad biking!), turning strangers into friends… and sometimes friends (temporarily!) against each other. The light-hearted gameplay, combined with immersive storytelling, got everyone talking, laughing and forming connections in a way that felt natural and exciting.
Camp Wildfire has brought us back five years running, and the crew we send has grown from one host to four.

Questions
Treachery!, answered.
How many people can play Treachery!?
- 16–30 a session. One host runs a session of up to 30; a bigger group plays in back-to-back sessions, so 150 people is five sessions through a day. At a festival, with more hosts, it has run for up to 200 players at a time.
How long is a session?
- About 50 minutes: a few to hand out the roles and the rules, then the nights and the votes until the traitors are caught or the loyal players run out. It fits a lunch break, a conference slot or the first hour of a party.
Where can you run it?
- Anywhere in the UK with a room: your office, a hired room, a pub function room, a conference hall or a festival field. Most of our bookings are in London; travel outside London is extra.
What do you need from the room?
- Chairs for everyone, ideally in a circle or a horseshoe, and somewhere the host can be heard. No set, no lighting rig, no crew: a microphone helps for 30 but isn't essential. We bring the rest.
Is it physical?
- No. Treachery! is played sitting down, in the open, with words: accusations, defences, alliances and votes. Nothing to climb, carry or run for, so every ability and every dress code plays on equal terms.
What does it cost?
- From £20 a person, with a minimum of £600 a session. No VAT to add: Get Social is not VAT registered, so that is the whole price. Travel outside London and any accommodation are extra; tasks between rounds are an add-on, priced on request.
Is it the TV show?
- No. The Traitors is the show; Treachery! is our own game, built on the classic Mafia rules and hosted so the arguing is the fun and nobody has to run it. If your team loves the show they'll know the shape at once: hidden traitors, a loyal majority, a "murder" every night and a vote every day. Tasks between rounds are an optional add-on.
What about a bigger group, or a whole conference?
- Sessions repeat through the day with the same host, so a conference of 150 is five sessions and a department of 60 is two. From £20 a person, minimum £600 a session. Send us the headcount and the slot and we'll come back with a plan.

What people say
From the room
Treachery was hands-down one of the best parts of Camp Wildfire. It was interactive, super engaging, and the perfect way to connect with other festival-goers. We were all talking about it for days after!
Tom, Camp Wildfire Participant
I went into Treachery not knowing what to expect, and by the end, I had made new friends and laughed harder than I had in ages.
