Secrets of Amersfoort Self-Guided Scavenger Hunt & Walking Tour

Step into the story

Find the squares. Beat him to the box.

When I was eight, my family left Amersfoort. I left something behind: a tin box with my first drawing, and a trail of eleven paper squares to find it.

1.5–2 hours
1–4 players per team

Start the mission

It begins
Born in this town, on the Kortegracht, on 7 March 1872. You know me by black lines and squares of red, yellow and blue.
It goes wrong
Tonight a forger, the Copyist, is on that trail. His buyer pays at midnight. If he wins, my first drawing is his, and his fakes become my story.
Your move
My first square waits round the corner, on the line of the old wall. The Copyist was here at dawn: turpentine, a flat portfolio, a roll of blue tape round his wrist.

An outdoor scavenger hunt through Amersfoort, run from your own phone and finished whenever you decide you are finished. Secrets of Amersfoort turns the streets themselves into the game.

Because it is GPS-based, the game always knows which corner you are on and gives you that corner's riddle, puzzle or photograph. The answers are never on the phone; they are out in Amersfoort, in front of anyone who bothers to look. What sticks afterwards is the part nobody tells you on a tour.

Among the stops: Mondriaanhuis (Mondriaan House), Varkensmarkt and Amersfoortse Kei. What you are hunting for is rarely at the stop itself but somewhere on the way, in something you would have walked straight past.

Mariënhof and Muurhuizen are on the route as well, and the group stops walking past things somewhere along the way and starts reading them.

The Walking Tour of Amersfoort Where Nobody Talks at You

It delivers what a walking tour delivers, a proper route through Amersfoort, and the story behind the thing in front of you, and removes the two parts people put up with: the commentary and the waiting. Here you walk, you look, you work it out. At intermediate difficulty most groups get most of it and disagree happily about the remainder. There are riddles, there is code-breaking, and there are photographs you would never have thought to take.

Had great fun playing secrets of Haarlem!

Planning a Fun Scavenger Hunt in Amersfoort?

You have found one. It takes a minute: pick a date, open the play link from your email, start when you want. No printing, no hiding things in advance, no list to compile, the route, the riddles and the photo tasks are already laid out across Amersfoort, roughly two hours and 3 to 4 km of walking. A single ticket at €19.95 covers four people sharing one phone.

An Outdoor Scavenger Hunt That Works for Any Group in Amersfoort

Adults. A scavenger hunt for adults in the sense that the puzzles actually resist you. Intermediate difficulty, riddles built on detail you have to go and look at, and two hours that hold a group that came out to enjoy itself.

Families. The distance bothers no child, and the photo tasks are where the youngest players get ahead of everyone. The riddles end up being a joint effort, which is exactly why a group of mixed ages works here.

Teams. Nothing to facilitate, nowhere to book, no start time to enforce. One ticket per four colleagues, every group loose in Amersfoort on the same route, and a comparison at the end. Several teams at once is what makes it a team scavenger hunt rather than a walk.

Couples and friends. No umbrella to follow, no group to stay with, no fixed pace. Stop where you like, take as long as you like, and finish knowing things about Amersfoort that most residents never learned.

Frequently Asked Questions

How does the Secrets exploration game work?

You book a date, get a link by email and open the play link from your email. At the starting point in Amersfoort you open the game on your phone. It is GPS-based: it knows where you are, and each location holds a riddle, a puzzle or a photo task. Solve one and the next location unlocks.

Is this a walking tour or a game?

It is both at once. The route through Amersfoort is the route a self guided tour would take and you learn the same things, except nothing is narrated, you get riddles instead of commentary, and there is no one at the front with a raised umbrella.

What do we need to bring?

A charged phone and shoes you can walk 3 to 4 km in. You get a link when you book and open the play link at the starting point, there is nothing to print, nothing to hide in advance and no equipment to collect.

How long does it take?

Two hours is typical, over a 3 to 4 km route. There is no clock and no scheduled departure, you fix the day when you book and start whenever you want on it.

How many people can play on one ticket?

€19.95 buys one ticket, one phone and one to four people around it. Larger groups split across two tickets and end up competing, which most of them prefer.

Is it hard?

Intermediate. Observation and sideways thinking do the work; you do not need to know the city, and nothing on the route is built to stop you permanently.

Is it suitable for children?

Yes. Children manage the 3 to 4 km easily and are usually the quickest at the photo tasks. The riddles are intermediate, so most families work through them together, which is how the game is meant to be played anyway.

Do we need to book a specific time?

No. You choose a date when booking, then start at whatever time you like on that date. There is no meeting point, no guide and no group to join.

What happens if it rains?

Rain is a pause, not a problem. Duck inside, let it pass, and carry on from the stop you were at, nothing is counting down.

Will we actually learn something about Amersfoort?

It is the whole design. Every riddle sits on something real, the history of Amersfoort, the people in it, the details nobody points out, so you come away with more than a visitor normally does. If a plot appeals more than a route, the other city games in Amersfoort have one.

Wir (Mein Mann, unsere 9-jährige Tochter und ich) haben heute ganz spontan das Spiel "Moordmysterie Düsseldorf" gebucht und gespielt. Die Buchung verlief schnell und reibungslos. Es hat super viel Spaß gemacht! Die Story, die Rätsel, das Konzept, die Route, die Gestaltung der App... richtig gut!!! Das Spiel würde ich vor allem Familien mit Kindern empfehlen. Für Erwachsene waren die Rätsel (meiner Meinung nach) zu einfach. Aber trotzdem wegen der schönen Route durch Düsseldorf, der Story, den lustigen Anweisungen zwischendurch eine schöne Aktion, die man zusammen machen kann.

I had a fantastic experience with CityGame! The concept is creative, engaging, and a great way to explore a city in a completely new way. The games are well-designed, combining puzzles, storytelling, and adventure so you’re constantly discovering something interesting around every corner. What I especially love is how CityGame turns a normal walk through the city into an interactive experience. It’s perfect for friends, families, or team outings, and it makes sightseeing much more exciting than the usual tours. Everything was easy to use, the challenges were fun and clever, and it really encouraged us to look closer at the city and its hidden details. Highly recommended if you’re looking for a unique and memorable way to explore!

This is an interesting way to conduct a self-guided Amsterdam city tour. It used the GPS on your phone to guide you to stops on a route. There are mini quizzes once you arrive at the stops on the path. The quizzes draw your attention to features in front of you or to a brief history of the place. In many cases, we visited a spot that would not have been obvious as a regular passer by. The tour as a whole was interesting to us as newcomers, but I would have liked more information on many locations we visited - a few links outside of the app for each place would have been helpful. Beyond that, the interface was a bit clunky and sometimes awkward to navigate. We definitely don't regret trying this out and feel like we got our money's worth on the experience.
