It's super fun to do. As soon as you get the email with the info (a few days before the start date) you can just start. So you go to the starting location whenever you want. You don't have to report anywhere or anything, so that's nice. You can walk quite a few meters but also see a lot of places of the city that you normally wouldn't see so quickly. Just outside the center. Very nice to see those places. We also stopped twice for a drink and toilet visit. You can do that just fine. The game itself is also very fun. The questions are not easy but certainly not too difficult. Thinking a little logically and you'll be fine. There were four of us and I understood that you could get the game on four phones. That was only not possible because it is not possible to get together in the team over the phone. However, a question to Tripadvisor was not answered. It wasn't supposed to kill the fun

We're a big fan of self-guided mystery tours. This was a good one, not a great one. Too bad that at the end the scoring didn't work. But we got a good discovery walk through the city, which was our goal

Was a cool trip... very well done...you can certainly do it in a larger group...you can only recommend... 👍🏻
