Follow a detective murder case through Nantes on foot, from the Basilique Saint Nicolas to the Château des ducs de Bretagne.

There is a body in Nantes. Balthasar is the name, and nobody is coming to work out who did it except you.

A self-guided detective game, played on foot in Nantes rather than around a table. The app keeps the case file, the streets keep the proof, and the murder mystery only moves when you do. There is no guide, no start time and no group - which is exactly the appeal.

Names that turn up in the case notes: Cathédrale Saint-Pierre-et-Saint-Paul de Nantes, Les Machines de l'Île and Tour Bretagne.

The Route Through Nantes

Add Place Graslin and Place Royale to that. The whole thing measures 3 to 4 km, which is a comfortable afternoon rather than a hike.

How Your Case in Nantes Plays Out

Walking is the mechanism. Between locations the witnesses come to you, each with a puzzle, a code or a photo task standing between you and what they know. Most groups need 1.5 to 2 hours for the 3 to 4 km, and a long pause costs nothing at all. The reasoning runs the way it does in a Sherlock Holmes story: small observations first, the accusation last.

Friends, Families and Colleagues in Nantes

With friends. Four people, one phone, one case. Somebody will back the wrong suspect early and refuse to let it go, and that is the part everyone remembers.

With your team. Buy a ticket per four, put every team on the same murder, compare the answers over lunch. Nothing to hire and nobody to brief, so a company outing in Nantes survives people turning up late.

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.

Questions People Ask First

How does the murder mystery game work?

It runs in the Loquiz app on your own phone. Open it at the starting point in Nantes, and from there the case comes to you: someone to question at each location, something to solve before they talk, and a name to hand in at the end.

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?

Four people per ticket, one phone between them, €19.95. A group of ten takes three tickets and turns into three teams, which is more fun than crowding one screen.

Do we need to book a time?

A date is all we need. The team starts when they like within 12 months of booking, because there is no host, no departure and nobody else's schedule involved.

Is it suitable for children?

Yes, from about eight. The difficulty is easy, the walking is gentle, and children tend to be the fastest in the group at the photo tasks.

What happens if it rains?

You decide when to play and you can pause whenever you want. Step inside, wait the shower out and pick the case up again - no clock is running and nothing closes.

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

It is a detective game first. But you see Nantes properly while you play it, and people tend to remember a street they searched better than one they were shown.

What else is there to do in Nantes?

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