General information
Deal overview
Traitor Party is the format that turns groups around. You are between 10 and 30 players, we distribute roles in secret, and from there everything becomes suspect. Who is really playing with you, and who has been manipulating you from the start.
Here, you will bluff, accuse, defend, hesitate, then regret. The game alternates collective phases, missions, votes and revelations, with continuous animation by a game master. It keeps the rhythm, it avoids downtime, and it builds in tension without you realizing it.
What you are actually buying is a supervised session for a large group, with game equipment, access to themed areas, souvenir photos, and a free drink at the bar. And yes, the theme bar is there for the logical continuation. Redo history, settle scores, or just laugh at the one who swore he was loyal.
You are looking for an activity that really works for a birthday, a bachelorette party, a bachelorette party, or a team evening. This one is made for that. Reserve, and prepare to doubt everyone, especially those close to you.
