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! I’m Heenah, a freelance graphic designer and artist. I’m originally from the UK, but I’ve lived in the Netherlands since 2018 and have absolutely fallen in love with the city of Leiden, where I live! I get endless inspiration just walking through the charming streets here. If you love history, art and architecture then definitely try out my Secret City Trail!

Hey, I’m Greg, a playful learning fanatic and big city enthusiast. I love showing things from a different perspective to create AHA-moments in the players. That’s what I strive for here with my games, and I hope you’ll find them both fun and interesting! I lived in Belgium and Ireland, and am a big fan of Dan Brown whose books give me inspiration for my stories and riddles over and over again. Play my games and let the questions guide you! Enjoy my gamified route in Budapest!

Salut! We are Deana and Pascal, both artists in love with all things to do with art in public space. We’re from Slovakia (Deana) and England (Pascal), working in music and visual art. Enjoy our discovery walk in Prague’s art district!
