A really fun experience! We played Moriarty's Game and loved it. We played in 2 groups of 4, which allowed us to engage in team building but also be competitive. The clues were clever - not too challenging but not too easy either (though a couple did take quite a bit of discussion to solve!) The landmark-based clues were surprisingly up to date! A nice touch is the inclusion of local shop keepers. I highly recommend Moriarty's Game, whether you're a Sherlock fan or not. I will be doing the other games soon.

Spent the whole day following clues and puzzles around a small area of London. Lots of good spots to stop and have a drink or some food along the way too. Some puzzles we felt confident about but others required a little more thinking but weren't impossible, all the clues were really thought out though and followed a good theme.

It was very enjoyable solving the clues whilst seeing lots of London’s quirky backstreets and sights you wouldn’t normally get to see. It was great to start & end in a pub for food & drink supplies. We thought it was well thought out, hard to begin with but loved the challenges.

I've done a couple of the games with friends, it's a great way to spend time in the Capital. The clues do make you think hard, solving is very satisfying. Interaction online is quick and easy and best of all it gets you off your backside and into little corners of London you'd never stumble upon on your own. Don't hesitate, just sign up and step into the Hidden City, you won't regret it.

I really enjoyed this. The clues made you think but weren't impossible. Got to discover a new area of London and it was really well thought out.

Great evening out around Marylebone to play this game - exploring lots of different places and being challenged by the clues. Will be doing the other ones….

I love getting to know different parts of London while playing a fun game that tests your powers of observation and teamwork! We've done several of the Hidden City games and they are all great!

Fun and enjoyable activity round central london. Clues are challenging and fun to solve, and well linked into the overall story line. Can be competitive with teams or take your time, building stops along the way. Overall a great way to spend the day. Highly recommend

As a family group of 6 all adults we thoroughly enjoyed the challenges, clues and locations undiscovered by us before. It was fun, sufficiently competitive and a really great social activity. A warm welcome from all your location partners added to our day. Thanks

Fantastic experience - very well organised and cleverly done. Super way to see London and found some absolute gems along the way. Can extend the experience as long as you wanted if you're not bothered about beating the clock! Would highly recommend as something fun and different to do, that challenges your brain too!
