We played as a 2, they recommend groups of 4 but if people are familiar with escape rooms you can play as a 2. There is a LOT to get through though and you likely won’t do it all. There were some bits we found very difficult. The aim is to steal as much from the bank as possible and then in the final 10 mins steal the final diamond. So you’ll get the full 60 minutes in the room to try and get the highest score possible
