How to get started...

Your challenge will begin in a secret location in either Chelsea or Sutton, where you’ll be welcomed by the team and then set off on your mysterious adventure. The challenge will take 2-3 hours to complete, and you can choose to take on rival teams and try to be the first to solve each conundrum, or go at your own pace.

Come on, Mr Marsden is waiting for you!
