Follow a detective murder mystery on foot through central Bonn, from Münsterplatz past the Altes Rathaus to Kaiserplatz, at your own pace.
A murder in Bonn, one victim called Balthasar, and a suspect list that only gets shorter if you go and look.
This is a self-guided murder mystery game you play outdoors, at your own pace, with Bonn 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.
Names that turn up in the case notes: Remigiusplatz, Münsterplatz and Beethoven-Denkmal.
Where the Case Takes You in Bonn
Sterntor Bonn Innenstadt and Altes Rathaus come into it too. Expect 3 to 4 km on foot, at whatever speed suits the slowest member of the group.
How Your Case in Bonn 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 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.
Friends, Families and Colleagues in Bonn
With friends. A better answer to "what shall we do today" than another cafe. It works as a pair and it works as a four, and it gives you something to disagree about over dinner.
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 Bonn survives people turning up late.
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.
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 Bonn, 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 Bonn 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?
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 Bonn?
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 Bonn?
There are other city games in Bonn built on the same idea and a different story, and Germany has plenty more where this came from.

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!
