Two and a half hours in Sofia. Four secret locations. Zero experience required. Maybe a teammate you cannot trust. In plain terms: a team spy adventure on foot, with the missions on your phones. The sights are nice. The real entertainment is your team: the debates on street corners, the plans that almost work, and the one person who takes it far too seriously. You will decode messages, photograph evidence, and keep a straight face in public. No experience needed. There may or may not be a double agent on your team. No app, no guide, no headset. About 2.5 hours and 1.7 km, with 4 stops that stay secret until you earn them. And then there is that one teammate who is never living down what happened at the third stop. You will have the photos to prove it. Who it's for: friends, couples and families with teens; and private groups, from bachelor and hen nights to work teams and active over-55s. Book a private game for 1 to 8 players on a date you choose; a team of one works too. Bigger groups play as several private teams.
