The experience

Can you stop a Mondriaan maniac from flooding Amersfoort? That's the premise you're working with: a gamified story that unfolds as you walk the city center and solve puzzles tied to real landmarks and hidden spots. You'll pass the Mondriaan museum (his birthplace), the Muurhuizen (houses built into the old city walls), the Kamperbinnenpoort gate, and the Koppelpoort, a rare combination land-and-water gate whose double treadmill still works. The Sint-Joriskerk sits on the Hof square, where you'll also find bars and restaurants around an old historic well. Each stop has a riddle to solve. The app gives you hints if you get stuck.

You need only a smartphone with a mobile data plan: no guide, no fixed departure time, no tickets to book separately. Start in the morning or afternoon. The route is roughly 2.5 kilometers and takes around two hours. Teams work best with two to six people aged 15 and older (younger players need supervision). The walking is flat and all areas are wheelchair accessible, so the physical demand is low. You move at your own speed, pause where you want, and come back to it later if you need to.

The story pulls you past the city hall (which has Mondriaan references in its art and square) and the Onze Lieve Vrouwetoren: the 98-meter Gothic tower nicknamed "Lange Jan" that rises above everything else and is the third-highest church tower in the Netherlands. You'll also spot the main shopping street with views of the monumental canal arches below the bridge. The riddles are designed to make you look closer at the architecture and history. Most of what you discover, locals walk past every day.
