There is only one correct path that gets you out of this maze. Only one person knows the answer (at first) and they will 'buzz' you if you make a mistake. As soon as that happens, you're out, and the person behind you starts over and tries to improve upon your success.
This is an excellent challenge for all ages; I remember the pressure of trying to recall the correct moves as my turn approached a few years ago in a team building exercise, and I was so excited when Ms. Newton' invited me to her class to observe her kids doing this very same activity.
Below is a short time lapse video from this 6th grade AVID class today. Awesome stuff!
