Secrets of Brussels 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.
Everything runs off your location. Stand somewhere that matters in Brussels and the game opens that spot's riddle, puzzle or photo task, and the only way through is to look up. Nothing is solvable from the screen. Two hours later you are the one in the group explaining the place to everyone else.
The route takes in Palace of Karel van Lotharingen, Queen Elisabeth statue and Brussels Parliament, and the walking between them is where most of the finding happens, what you need is out there in front of you, never on the screen.
You also reach Manneken Pis and Brussels Stock Exchange (Bourse). Everyone works out soon enough that the useful detail is never the obvious one.
The Walking Tour of Brussels Where Nobody Talks at You
A self-guided tour with the guide replaced by riddles. The route through Brussels is real, the history is real, and the difference is that you dig it out instead of being handed it, no commentary, no umbrella to follow, nobody held up at the back. Intermediate difficulty: most groups solve most of it, and the rest is a good argument. Riddles, code-breaking, and photographs you would otherwise never have taken.
Had great fun playing secrets of Haarlem!

Looking for a Scavenger Hunt to Do in Brussels?
This is one, already built. Setting it up is a ticket and a link: book, open the link in your phone's browser, begin whenever you feel like it. Nothing gets printed, nothing gets hidden beforehand and no list gets written, because the route through Brussels, the riddles and the photo tasks all exist, about two hours over 3 to 4 km on foot. One ticket is €19.95 and covers up to four people on one phone. It is the same evening you were going to spend writing clues, spent walking instead.
An Outdoor Scavenger Hunt That Works for Any Group in Brussels
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. A corporate scavenger hunt that needs no facilitator, no room booking and no scheduled start. Buy one ticket per four people, send the teams into Brussels on the same route, and compare who found what. Running several groups at once is what turns it into a competition.
Couples and friends. A self guided tour with nobody to follow and nothing to keep up with. You choose the pace and the stops, and you come away with facts about Brussels that would surprise a local.
Frequently Asked Questions
How does the Secrets exploration game work?
It runs in your phone's browser, no app to download. After booking you get a link, walk to the starting point in Brussels and begin. The game reads your location, gives you that spot's riddle, puzzle or photo task, and unlocks the next one when you have it.
Is this a walking tour or a game?
Both, and that is the point. It follows a walking route through Brussels 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 phone with battery and shoes that handle 3 to 4 km. You get a link when you book and open the game in your phone's browser when you get there, no printing, no hiding things in advance, no kit to collect from anyone.
How long does it take?
About two hours, covering 3 to 4 km on foot. There is no time limit and no fixed start, you pick no date when booking, your ticket is valid for 12 months and you begin on whatever day and at whatever time suits you, so a slow group simply takes longer.
How many people can play on one ticket?
Between one and four people share a single phone on one €19.95 ticket. Beyond four, take a second ticket, two groups on the same route can race each other, which is the better way to do it anyway.
Is it hard?
It sits at intermediate. What it asks for is attention and lateral thinking rather than local knowledge, and no riddle is obscure enough to end the afternoon.
Is it suitable for children?
Yes. The distance is ordinary walking for them and they are normally first through the photo tasks. Intermediate riddles mean the family works them out together, which is how it is designed.
Do we need to book a time slot?
No. You choose no date and no time when booking: your ticket is valid for 12 months, so you start on whatever day and at whatever time you like. There is no meeting point, no guide and no group to join.
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 Brussels?
That is the point of this one. The riddles are built on the history, the characters and the odd details of Brussels, so you finish knowing things most visitors never find out. If you would rather have a story than a tour, look at the other city games in Brussels instead.

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.
