Great Day out !Hidden City Moriarty's Game . 100% Reccomend You wont be dissapointed! - We had a great time from start to finish. We split into 2 teams, solved clues and had some great stop offs where we obtained more clues to solve, the people we encountered were very friendly and part of the game. It is very well organised and takes you on an adventure, we went through places we had never seen before, and was able to take everything in while enjoying the game. I would 100% Reccomend! I brought this as a Christmas treat for the family to enjoy together. It was so worth it ! We are now Planning the next !

Superb fun walking around beautiful parts of Marylebone and Mayfair, great clues. - A fantastic day walking around parts of London we had never been to before. Really well organised and executed, everything gets delivered to your phone on WhatsApp. Take a battery pack though as you'll have your phone on all day. Great clues and fun to decode, quite hard in places but very, very enjoyable. We did the Spectre one too which is excellent. Will do one of the other ones as well.

Perfect way to spend a summer day - Super fun experience! We were a team of two and took around 3h and a half to finish it. Got us walking around Marylebone, riddles and puzzles were super fun, real brain-scratchers some of them. We tried to ask for as little hints as possible so it was challenging. It’s really recommended if you want a fun activity with the family/friends while being outside and enjoying some fresh air!

Excellent game - This game was super fun to do with friends!! I would recommend it to groups of any sizes as you can split into separate groups and compete. Lots of twists along the way and took us round some beautiful parts of London that you wouldn’t normally explore!

Become your own detective! - If you want to find hidden treasures of London whilst having a bit of fun solving clues and taking a walk around a great city then this is for you. We enjoyed some great pubs and food. A couple of the clues were a bit tricky but you can ask for help easily. We will definitely be doing another one!

Hidden City Moriarty - Lots of fun exploring a part of London I hadn't before. Just the right amount of helpful clues and stops on the way. Clearly thought and effort has gone into the set up. We will try another soon

Brilliant day had by all. - We completed Moriarty’s Game: The Professor’s Invitation yesterday. We had a blast! The game is very well organised and sends you on quite the adventure around some of the lesser known areas of London if you are a tourist like myself! We visited some lovely places that we never would have dreamt of going to had we not been chasing down clues! Some of the clues were hard! At first we thought we had bitten off more than we could chew but once we got the hang of it it was a brilliant experience! We had to ask for one hint which cost us a 10 minute time penalty and we got lost once, but we completed the final mission after 3 hours and 14 minutes which is a terrible time compared to the super sleuths on the leaderboard!! There must be some real brain boxes out there! However, we enjoyed some drinks and a lovely pub meal along the way. All in all a very enjoyable experience and I would highly recommend. We can’t wait to play the next one!

Great for puzzlers! - A well-designed game, taking us to places that we would not have visited, keeping us puzzled with manageable navigation clues along the way
