Decode the message. Photograph the evidence. Keep a straight face. Try to look like you belong in Fargo. In plain terms: your team explores on foot and takes on spy missions together. The mission is the excuse. The real game is figuring out which of your teammates has been lying since the first stop. Some missions need a sharp eye, some need a little nerve, and some need everyone talking at once. No puzzle skills required, just a sense of humour. There may or may not be a double agent on your team. About 2.5 hours, 4 stops and roughly 3.4 km on foot. There is no guide, so nobody will make you stand still and listen. The photos are a bonus. The real souvenir is the storey your group keeps bringing up long after the mission ends. 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.
