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 was murdered in Nice. No incident room, no colleagues, no forensics - just you, a phone and the streets he was last seen in.

This is a self-guided murder mystery game you play outdoors, at your own pace, with Nice 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 case takes you past Marc Chagall National Museum, Colline du Château and Cathédrale Sainte-Réparate de Nice.

The Route Through Nice

Add Monastère de Cimiez and Marine Penthouse - Heart of the Old Town 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 Your Case in Nice 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.

Who Plays This in Nice

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. Split into fours, buy a ticket each, and send them off on the same murder. Team building without a facilitator, a venue or a start time - and in Nice that means nobody has to be anywhere by nine.

With kids. Eight and up manage it comfortably. Children are usually quickest on the photo tasks, and teenagers who have stopped being impressed by old buildings get competitive about the puzzles instead.

Frequently Asked Questions

How does the murder mystery game work?

It runs in the browser on your own phone, no app download needed. Open it at the starting point in Nice, 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?

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 book a date, not a time slot. Start whenever you like on that day, because there is no host, no departure and nobody else's schedule involved.

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?

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 Nice?

Both, in practice. You cover Nice 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 Nice?

You can play more than one: other city games in Nice use the same streets for another case, and the rest of France is one list away.

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.
