Hoi, I am Frans. I was born and raised in a small village close to Amsterdam. I studies physics in Amsterdam and ended up in Maastricht working for a medical device company. Around 2000 I decided to change my careerd and started an event agency TreaT, catering for business events in Maastricht. In 2013 I created CityGoose citygames in the Netherlands; self-guided city discovery games with a physical game. In 2022 we acquired Secret City Trails, which is like the next logical step to expand my discovery ambitions. I love board games, puzzles and good food and hope you enjoy the different discovery walks I made.

Hi riddlers. We are Seraphin and Stefanie. While both of us were studying in Zürich we became close friends and started to discover mysterious sites around the city. Travelling the world we enjoy to dive into cultures that are new to us and their myths. With our city game through Zürich we love to show you some of the city’s best kept secrets.

Hi there fellow adventurer, I’m Neil! I’m a playful London resident with a comprehensive knowledge of its neighbourhoods, cultures and quirks, and an enthusiasm for discovering and sharing the hidden gems beyond the guidebooks! You get to know a city in a completely different light when exploring on foot, and there’s no better way than seeing it through the eyes of a local! I’m so excited to introduce you to the vast urban playground of London, to tell you tales of its colourful history, show you the REAL hotspots, and most of all to put some fun into your visit! My South Bank game, Peckham walk, Surrey Quays route, Rotherhithe Riverside trail and Hampstead experience are ready and waiting for you!

Hi there! We are Dora and Adam, two Budapest enthusiasts, born and raised in Buda (he) and Pest (she)! We also love games, puzzles and any kind of brain-teasers, whether a cryptic ad in the metro, the latest season of Lupin or board games such as the Gaia Project. We hope that our Budapest’s Castle Hill trail will be a nice addition to this trend!
