San Francisco has a reputation to uphold. Your team is about to test it. In plain terms: your team explores on foot and takes on spy missions together. Come for the city. Stay for the moment your most sensible teammate says yes to something bold, and everyone talks about it for the rest of the day. The missions are only half the game. The other half is watching each other, because at the final stop your team votes on who might be a double agent. There may not be one at all. About 2.5 hours, 4 stops and roughly 2.9 km on foot. There is no guide, so nobody will make you stand still and listen. San Francisco will recover by the end of the day. Your group now has at least one storey it will keep retelling. 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.
