This escape room is one best designed escape room I've done. It's a bit on the trickier side, being marketed as a difficult room by Riddle Room. It has a large number of puzzles that must be done in parallel to escape in time - large groups are advised. Having a large number of puzzles means that each person gets to solve a number of puzzles on their own or in pairs. All puzzles are unique, challenging but not too tricky. I would highly recommend this room for a larger group of experienced people.
