Imagine—you're trapped in an abandoned subway station with a dozen strangers, thanks to an unstable conspiracy theorist who's holding you all hostage. It might sound like the premise for a thriller flick, or a suspenseful reality show, but it's actually the setup at Great Room Escape, a game that gives groups one hour to find their way out of a dire situation. By using clues and items left in the space, teammates work together to figure out the best way to escape. Friends can sign up for fun, though Great Room Escape is also a popular corporate team-building activity.
