Somebody killed Balthasar in Brussels. The evidence never left the neighbourhood, which is where you come in.
This is a self-guided murder mystery game you play outdoors, at your own pace, with Brussels for a board. Your phone carries the case file and the city carries the evidence. Clues to gather, digital characters to question, codes to break and a name to give at the end - a detective game with no host at a meeting point, no timetable and no group to keep up with.
The file sends you to Musée des Instruments de Musique, Musée Magritte Museum and Parc de Bruxelles.
The Route Through Brussels
Musée de la Ville de Bruxelles and Galeries Royales Saint Hubert belong to the same case. You cover 3 to 4 km in all, and there is nothing stopping you sitting down halfway.
Had great fun playing secrets of Haarlem!

Playing the Detective Game in Brussels
The story arrives as you move. Every location holds something to work out, and the digital characters you meet each know one piece of what happened to Balthasar. Reckon on 1.5 to 2 hours and 3 to 4 km, but there is no clock: break for lunch and pick it up afterwards. It asks the sort of attention Sherlock Holmes made his name on - the detail other people step over.
Who Plays This in Brussels
With friends. A better answer to "what shall we do today" than another cafe. It works as a pair and it works as a four, and it gives you something to disagree about over dinner.
With your team. Two teams on one case turns it competitive, which is the whole point. No booking a room, no briefing, no waiting for stragglers: a team outing in Brussels that starts when the last person shows up.
With kids. Eight years old is about the floor. The distance is not the problem it sounds like, the photo tasks are where children beat adults outright, and the codes end up being solved by the whole family at once.
Frequently Asked Questions
How does the murder mystery game work?
You play it through a direct link in the browser on your own phone. It opens in Brussels, the story moves with you, and every stop holds a puzzle, a code or a photo task standing between you and the next piece.
How long does it take?
Set aside an afternoon. The case itself takes 1.5 to 2 hours across 3 to 4 km, but nothing counts down and nothing shuts, so the breaks are free.
How many people can play on one ticket?
One €19.95 ticket covers four players on a single phone. Past four, take a second ticket: two teams chasing the same killer beats six people squinting at one screen.
Do we need to book a time?
Just a date. The hour is yours to choose, because nobody is standing anywhere in Brussels expecting you - no meeting point, no guide, no group.
Is it suitable for children?
Eight and up handle it well. Nothing along the way is beyond them, and more often than you would expect it is the youngest player who notices the detail that decides the case.
What happens if it rains?
Rain is an interruption, not a problem: you choose the moment to start and you can stop as long as you like. Plenty of groups split the case over a morning and an afternoon.
Is this a detective game or a walking tour of Brussels?
Both, in practice. You cover Brussels on foot and you notice far more than you would on a normal walk, because the case gives you a reason to look closely at things you would otherwise pass.
What else is there to do in Brussels?
There are other city games in Brussels built on the same idea and a different story, and Belgium has plenty more where this came from.

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.
