The story
Mr Kettle has gone for a sandwich and left five locks between you and the vault. Our hardest room runs 75 minutes, because you will need every one of them.
Kettle & Sons is our expert room: layered puzzles, two parallel tracks and a final lock that needs the whole team at once.
Best for groups of four to eight who have done a few rooms before. Fewer than one in four teams get out.
