Valparaiso is famous for plenty of things. Your team's poker faces will not be one of them. In plain terms: a 2.5-hour team spy game on foot, played on your phones. 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. Step-free mapped paths all the way: 2 km, 4 stops and about 2.5 hours, at whatever pace your team likes. No guide, nothing to download. You head home with the photos, the in-jokes, and conclusive proof of whose poker face needs work. 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.
