Solve a murder mystery on foot in Duisburg, from the Rathaus down to the Innenhafen and back, playing at your own pace.
There is a body in Duisburg. Balthasar is the name, and nobody is coming to work out who did it except you.
This is a self-guided murder mystery game you play outdoors, at your own pace, with Duisburg 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 investigation puts Church of Our Saviour, Innenhafen Duisburg and Kultur- und Stadthistorisches Museum on your list.
Where the Case Takes You in Duisburg
Lehmbruck Museum and Philharmonie Mercatorhalle Duisburg are on the route as well. Anyone keeping decent notes will find they only have to confirm there what they already suspect.
Playing the Detective Game in Duisburg
The story arrives as you move. Every location holds something to work out, and the digital characters you meet each know one piece of what happened to Balthasar. Reckon on 1.5 to 2 hours and 3 to 4 km, but there is no clock: break for lunch and pick it up afterwards. It asks the sort of attention Sherlock Holmes made his name on - the detail other people step over.
For Families, Friends and Teams in Duisburg
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 Duisburg that means nobody has to be anywhere by nine.
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.
Frequently Asked Questions
How does the murder mystery game work?
It runs in the Loquiz app on your own phone. Open it at the starting point in Duisburg, 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?
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?
Just a date. The hour is yours to choose, because nobody is standing anywhere in Duisburg expecting you - no meeting point, no guide, no group.
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?
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 Duisburg?
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 Duisburg?
You can play more than one: other city games in Duisburg use the same streets for another case, and the rest of Germany is one list away.

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.

This was a fun game! It had a few challenges which was good and surprises. It got me to go around and explore Queenstown, New Zealand. I got to places in Queenstown, New Zealand I hadn’t been to before while on holiday here. Thank you for that and it gave a feel what it would be like to be the actual Sherlock Holmes!
