We're big fans of Seattle-based "escape the room" designers Puzzle Break, so we teamed up with them to run a big, 100+ person party during PAX. The premise is simple: you're locked in a room with a group of other people and given one hour to find the key to escape. Most groups don't finish in time, but it's still the best team-building exercise ever. Turning a puzzle game into a multiplayer experience creates three distinct aspects of play: finding the clues, assembling those clues, and then using them to solve the puzzle. People who normally might not enjoy the solo experience of a traditional puzzle game, such as those who enjoy exploration or communication, will find lots to do here. Even traditional puzzle solvers will need to apply different types of logic to solve the wide variety of challenges in the room. This set-up allows everyone to display their talents, and rewards groups for having a diverse set of skills. It also teaches you a lot about the members of your team!
