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
It beginsAnd we need you to find out who killed Balthazar.
It goes wrongYou ring the bell. Nobody opens the door but you catch a shadow moving through the house! Somebody is home!
Your moveWalk 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 is dead in Trier, and whoever closes the case is going to have to walk it.
A detective game that uses Trier as its playing field. The investigation lives on your own phone, the witnesses are digital, and the answers are out there in front of you rather than on the screen. No host, no fixed departure, no waiting for anyone.
The file sends you to Judengasse, Liebfrauenkirche and Steipe.
The Route Through Trier
Add Dreikönigenhaus and Frankenturm Trier (Historisches Gebäude) 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 Trier
You walk and the case reaches you in pieces. Digital characters wait along the way, each with part of the truth and each wanting something first: a puzzle, a code, a photograph. Whatever you solve crosses a name off the list. Allow 1.5 to 2 hours over 3 to 4 km, though nobody is timing you - stop for an hour and the case waits. 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.
Who Plays This in Trier
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 Trier 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.
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 Trier, 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?
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?
You pick a date, not a slot. Start at nine or start at four; nothing in Trier 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?
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 Trier?
You get the walk either way. The difference is that you arrive at each place with a question, and a question makes people look at a building far harder than a plaque ever does.
What else is there to do in Trier?
There are other city games in Trier built on the same idea and a different story, and Germany 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.
