Detective Murder Mystery Game Maastricht

Step into the story

A murder in the city

You are Sherlock Holmes, and Watson is at your side. Balthazar has been found dead, four people had a reason, and only one of them did it.

1.5–2 hours
1–4 players per team

Start the mission

It begins
And we need you to find out who killed Balthazar.
It goes wrong
You ring the bell. Nobody opens the door but you catch a shadow moving through the house! Somebody is home!
Your move
Walk the city, question the witnesses, gather the evidence and name the killer. Good luck, and have fun.

Every player takes on one of these roles.

The Reasoner
The Lookout
The Photographer
The Casebook

Balthasar died in Maastricht and the file lands on your phone. Everything you need to close it is out there on the street.

A self-guided murder mystery game for people who would rather walk than sit. Maastricht holds the evidence, the app holds the file, and the puzzles, codes and photo tasks in between are what narrow a long suspect list down to one name.

The file sends you to Bonnefanten museum, Vrijthof and Sint Pieter Fort.

Where the Case Takes You in Maastricht

Add City Hall and Natuurhistorisch Museum Maastricht to that. The whole thing measures 3 to 4 km, which is a comfortable afternoon rather than a hike.

Had great fun playing secrets of Haarlem!

How the Murder Mystery Game Works in Maastricht

Nothing happens until you walk. The evidence is at the locations, the witnesses are on the phone, and every puzzle, code and photo task you get through hands you another piece of Balthasar's last day. 1.5 to 2 hours, 3 to 4 km, no time limit of any kind. It asks the sort of attention Sherlock Holmes made his name on - the detail other people step over.

Who Plays This in Maastricht

With friends. Four of you on one phone and everybody gets a say. Somebody always commits to a theory early, loudly, and wrongly - that is half of what you will talk about afterwards.

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 Maastricht that starts when the last person shows up.

With kids. The puzzles work from about eight years old. Younger ones walk along and help, older ones take over the phone, and the whole thing survives being interrupted by ice cream.

Before You Book

How does the murder mystery game work?

Everything opens from the play link in your email. Start it wherever you like in Maastricht, follow what the case tells you, solve what each location puts in front of you, and hand in a name when you are sure.

How long does it take?

Between one and a half and two hours for most groups, across 3 to 4 km. Slower is free: nothing is timed and nothing expires while you are having lunch.

How many people can play on one ticket?

One ticket covers one to four players on a single device, €19.95 in total. Bigger groups buy one ticket per four and race each other through the same murder.

Do we need to book a time?

You pick a date. Start at nine or start at four; nothing in Maastricht is waiting on you and no guide is standing anywhere.

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?

Nothing forces you to keep walking. Duck into a cafe, let it pass and carry on when you feel like it - there is no time limit on any part of this.

Is this a detective game or a walking tour of Maastricht?

Both, in practice. You cover Maastricht 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 Maastricht?

There are other city games in Maastricht built on the same idea and a different story, and the Netherlands 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.
