Houdini's Magic Cell

My husband and I have done almost 30 escape rooms and the thought we could handle what they claim is their most challenging room. The only challenge was trying to understand the clue that was given which we still didn't understand after the game master explained it a few times. Normally we fly through the harder puzzles. Each room at this place is just one tiny room with a bunch of props that don't have to do with anything and a few locks to solve.

Single room. Only locks. 50 mins not 60. No cameras so you press a button to get a hint and have to wait for the game master to walk over into the room .. when they eventually see you are calling them.
