We created the game called PuzzLair, which is one of the top attractions on Tripadvisor in the city of Bristol. We made 2 rooms there, but planning to create 2 other games as well. The ones are the John Monroe dectective office, and the other is the Secret Laboratory of Dr. Lev Pasted.
The activity is said to be one of the best attractions in Bristol by the players who had been there and succeded or not succeded. Most of the players who can not make it on time (60 minutes) are still feeling themselves very excited about the game.
Here is the website if you want to book a game at them or just to have some more informations on the game rooms: http://www.puzzlair.co.uk
