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

A murder in Frankfurt, one victim called Balthasar, and a suspect list that only gets shorter if you go and look.

This is what a murder mystery looks like once you take it outside. Frankfurt is the crime scene, your phone is the case file, and the two hours in between are yours to spend how you like - a self-guided detective game with nobody standing over it.

Part of what the route covers: Historical Museum Frankfurt, Stoltze-Museum and Römerberg.

The Route Through Frankfurt

New Old Town and Eiserner Steg are on the route as well. Anyone keeping decent notes will find they only have to confirm there what they already suspect.

Had great fun playing secrets of Haarlem!

How the Murder Mystery Game Works in Frankfurt

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 habit is the one the Sherlock Holmes stories are built on: notice the thing nobody else bothered to look at, then say out loud what it means.

For Families, Friends and Teams in Frankfurt

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 Frankfurt 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?

You play it through a direct link in the browser on your own phone. It opens in Frankfurt, 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 Frankfurt 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 Frankfurt?

It is a detective game first. But you see Frankfurt 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 Frankfurt?

You can play more than one: other city games in Frankfurt use the same streets for another case, and the rest of Germany 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.
