We didn't enjoy this much. A lot of the riddles were quite frustrating as there were no instructions of what was expected and there was a lack of interactivity (e.g. for one of the riddles a picture was sliced up and scrambled and you had to move it back into the right order, but you couldn't just slide the images into the correct position. We had to find somewhere to sit and make notes on a second phone to then type in the number order.) The biggest shame of it all was that you spend the entire time looking at your phone to read out the information or to solve the riddles, instead of looking around you and enjoying a tour through the town. We recently did a different tour from voicemaps where you put your phone in your pocket for the whole tour and it uses your GPS location to play audio information as you walk past certain spots. That was a lot nicer as you get to look at everything around you and hear the information instead of having to look at your phone all the time.
