We chose the toughest one, it was a Sherlock Holmes room. The rooms were very funky! We had to escape a train. Below are pictures from in the room. It was basically number related clues that make you unlock a padlock to get the next clue to the next padlock.
It was really tough and we didn't' solve any of the clues. They were pretty abstract and on top of that, one of the locks was broken so we'd never have been able to unlock it. The lady told us after that no one had ever got out that room, which is not really a surprise.
It was good fun and only about a fiver per person. I may go back again and start with the 'Alice in Wonderland' room which is a bit easier.
