Great day out. Clues were suitable for all the family aged 10 and upwards. Saw new parts of London and enjoyed the pubs too. Would definitely recommend. I would suggest it’s a dry day activity as lots of time outdoors. The booking is flexible and we changed our date as it was forecast to rain on our original date.

This was the best. We had so much fun chasing the clues around London - they kept us engaged and it was funny bumping into other people who we spotted playing the game with us and trying to beat them to the finish line. We’re Londoners and still happened across so many nice spots we wouldn’t have found otherwise. We’ll definitely do it again! It would be great to get more themed challenges to do as well.

Wow! This highly entertaining & clever game, kept us engaged for hours! We did it as a family & the kids loved it too, as it enabled us to explore parts of London we had never experienced or seen. It was exceptional, up to date, with seasonal references and great interaction. It was good to know that their was help at hand if we got lost, but we did our best not to ask for help. ;) We will endeavor to retrace our steps one day, to enjoy some of the lovely watering holes we discovered on route too.
