Really fun walking escape room game, loved the neighborhood vibes and fun puzzles - We had a super time on this 'outdoor escape room' during our recent holiday in London - it was definitely harder and more involved than we anticipated, but in a good way. I don't want to give away too much, but it was great to walk through London neighborhoods which we would not have discovered otherwise; the stops along the way were perfect and the colleagues were all really kind to us; and the clues were quite challenging but overall do-able. The WhatsApp interface worked well and we only had a couple of small difficulties, one of which unfortunately was that only one of our phones worked with the tech, and we were with our two kids aged 14 and 11, so it was a little hard to involve everyone with the walking clues with only 1 phone to look at. The price/value was fine for paying for 2 of us but it would have felt quite expensive to pay for all 4 of us as a family for what we got, so a suggestion could be to offer some sort of family/bulk pricing. But overall, we really enjoyed this and would definitely do another one of their games if we get back to London again soon.

Great fun and great value - We love walking in London, we love escape rooms. This is the best of both worlds. Four hours of navigating streets using cryptic clues and stopping along the way to answer series of clever questions. It was huge fun and a really lovely way to spend a day in our favourite city. I suspect we took longer than other players but it really didn't matter - for us, it was taking the time to enjoy looking at things in London that we would not have noticed at other times. Brilliant idea and exceedingly well executed. Looking forward to trying one of the other games on offer.

Moriarty’s game - Moriarty’s game was really good, exploring the back streets of Marylebone/Mayfair. The clue were interesting and challenging enough.

Fantastic experience! - Such a fantastic experience. The puzzles were difficult and you had to think outside the box, which we loved. The pubs were nice and always in places we wouldn’t have found otherwise. A fabulous way to spend a day and see the parts of London we wouldn’t have seen otherwise.

A fun afternoon - A really fun afternoon! I was worried you’d have to know lots about Sherlock Holmes but you didn’t at all. It was great. All the pubs were welcoming and it wasn’t intimidating at all! Would 100% recommend and we will get some friends together to do another one now.
