Adventure Rooms Cardiff: The Mad Scientist

This one was the first we had tried and worked well with a mixture of puzzles suitable for the various people in the group (1 a child)
Had to be slowed down at one point as were able to solve a puzzle without cracking the lock (so a hint came up on how to do the lock - but as the GM said afterwards he did that because he could see what I was doing)
A good introduction to escape rooms
