Play a detective murder mystery on foot in Heidelberg, from the Heiliggeistkirche over the Alte Brücke to the castle, at your own pace.
Somebody killed Balthasar in Heidelberg. The evidence never left the neighbourhood, which is where you come in.
A self-guided murder mystery game for people who would rather walk than sit. Heidelberg holds the evidence, the app holds the file, and the puzzles, codes and photo tasks in between are what narrow a long suspect list down to one name.
You will be standing at Alte Brücke, Marktplatz and Heiliggeistkirche, among other places.
Where the Case Takes You in Heidelberg
So do Jesuitenkirche and Universitätsplatz. The route runs 3 to 4 km and rewards the people who look up rather than the people who walk fast.
How Your Case in Heidelberg Plays Out
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. 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 Heidelberg
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. 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 Heidelberg 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?
Everything sits in the Loquiz app. Start it wherever you like in Heidelberg, 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?
About two hours of playing and 3 to 4 km of walking. How long the whole outing takes is up to you, because you can stop for as long as you like and carry on after.
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 Heidelberg 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?
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 Heidelberg?
Both, in practice. You cover Heidelberg 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 Heidelberg?
There are other city games in Heidelberg 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!
