Secrets of Heusden Self-Guided Scavenger Hunt & Walking TourStep into the story

Find the theses. Reach the chest first.

When I left for Utrecht in 1634, I left a chest behind in Heusden. The way to it hides behind eleven theses: numbered slips, the way I set out every argument.

  1. Secrets of Heusden Self-Guided Scavenger Hunt & Walking Tour – It beginsIt begins

    Gijsbert Voet, if you are from here. I was born in this fortress while they were still building its walls.

  2. Secrets of Heusden Self-Guided Scavenger Hunt & Walking Tour – It goes wrongIt goes wrong

    Tonight a dealer in old papers, the Collector, is on the trail. At midnight she auctions whatever she finds. If she wins, the chest leaves Heusden for good.

  3. Secrets of Heusden Self-Guided Scavenger Hunt & Walking Tour – Your moveYour move

    My first thesis waits at the harbour, just north, where old guns still watch the water. The Collector passed here an hour ago: white gloves, a silver gavel swinging on a chain.

Secrets of Heusden hands you the streets themselves as a puzzle. It is a self-guided scavenger hunt on your own phone, no guide, no group, no departure time.

It works off GPS, so the game knows where you are and hands over that location's riddle, puzzle or photograph. All of it points outward, at Heusden rather than at the phone. The history arrives sideways, through the puzzles, which is why it stays with you.

Oude Herptse Poort, Grote of Sint-Catharinakerk and Wijkse Poort are among the places you reach. The finding mostly happens in between, and none of it can be answered without actually standing there.

Het Gouverneurshuis and Vestingwerken Heusden 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 Heusden Where Nobody Talks at You

It delivers what a walking tour delivers, a proper route through Heusden, 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!

Looking for a Scavenger Hunt to Do in Heusden?

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 Heusden, roughly two hours and 3 to 4 km of walking. A single ticket at €19.95 covers four people sharing one phone. Anyone who has tried to build one of these knows how long that takes.

A Scavenger Hunt for Adults, Teams and Families in Heusden

Teams. Nothing to facilitate, nowhere to book, no start time to enforce. One ticket per four colleagues, every group loose in Heusden 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.

Adults. As a scavenger hunt for adults it has real bite, this is not a printable list of things to spot. The difficulty is intermediate, the riddles reward looking at what is in front of you, and the two hours hold up for a group that came to be entertained.

Families. Children walk it without trouble and are usually the fastest at the photo tasks. The riddles are the part you solve together, which is what makes it work for a group with a wide spread of ages.

Couples and friends. A self-guided walking tour that does not involve following an umbrella. You set the pace, stop where you want, and end up knowing things about Heusden that most people who live there do not.

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 Heusden 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?

Both, and that is the point. It follows a walking route through Heusden the way a self-guided walking tour does, and you pick up the history as you go, but instead of a commentary in your ear you get riddles to solve. Nobody walks in front of you holding a sign.

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, the 3 to 4 km is no obstacle and the photo tasks are where younger players get ahead. The riddles sit at intermediate, so families tend to solve them as a group, which is the intended way round.

Do we need to book a time slot?

No, only a date. The hour you actually begin is yours, and there is nobody waiting: no meeting point, no guide, no group.

What happens if it rains?

You play when it suits you and stop when it suits you, so a shower just means a coffee. No timer is running, and the route is exactly where you left it.

Will we actually learn something about Heusden?

That is the point of this one. The riddles are built on the history, the characters and the odd details of Heusden, so you finish knowing things most visitors never find out. Everything practical, starting point included, is on the Heusden page.

    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.
