Trust no one in Idaho Falls. Especially not the teammate who keeps volunteering for lookout duty. In plain terms: your team explores on foot and takes on spy missions together. No guide means no one to impress and no one to blame. Just your crew and 2.5 hours of increasingly bold decisions. Puzzle experience is optional. Every mission goes better with a brave volunteer, and somebody will volunteer the wrong person. There may or may not be a double agent on your team. About 2.5 hours and 4 stops over roughly 1.6 km. Your phone is your handler and your only witness, and there is nothing to download. You leave with the photos and some pointed questions for whoever was so very keen to keep watch. 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.
