Explore Duisburg on a self-guided exploration game that starts on the Alter Markt and leads you through the old centre with puzzles to solve.
A scavenger hunt that uses the streets themselves as its board: Secrets of Duisburg runs on your own phone, starts when you say so, and takes exactly as long as you let it.
Your position drives the whole thing: each location unlocks a riddle, a puzzle or a photo task as you reach it. To solve them you have to read Duisburg itself rather than a screen, and that is why you walk away knowing things the average local does not.
Among the stops: Skulpturenpark Lehmbruck Museum, Church of Our Saviour and Historische Stadtmauer. What you are hunting for is rarely at the stop itself but somewhere on the way, in something you would have walked straight past.
Rathaus Duisburg and Mercatorbrunnen are on the route as well, and the group stops walking past things somewhere along the way and starts reading them.
A Self-Guided Walking Tour of Duisburg, With Riddles Instead of a Guide
It delivers what a walking tour delivers — a proper route through Duisburg, and the story behind the thing in front of you — and removes the two parts people put up with: the commentary and the waiting. Here you walk, you look, you work it out. At intermediate difficulty most groups get most of it and disagree happily about the remainder. There are riddles, there is code-breaking, and there are photographs you would never have thought to take.
Planning a Fun Scavenger Hunt in Duisburg?
You have found one. It takes a minute: pick a date, download the Loquiz app, start when you want. No printing, no hiding things in advance, no list to compile — the route, the riddles and the photo tasks are already laid out across Duisburg, roughly two hours and 3 to 4 km of walking. A single ticket at €19.95 covers four people sharing one phone. Anyone who has tried to build one of these knows how long that takes.
A Scavenger Hunt for Adults, Teams and Families in Duisburg
Adults. A scavenger hunt for adults in the sense that the puzzles actually resist you. Intermediate difficulty, riddles built on detail you have to go and look at, and two hours that hold a group that came out to enjoy itself.
Couples and friends. A self guided tour with nobody to follow and nothing to keep up with. You choose the pace and the stops, and you come away with facts about Duisburg that would surprise a local.
Teams. One ticket covers four people, so a department divides straight into groups running the identical route through Duisburg. No host to hire, no venue to reserve, no departure time. Put three or four teams on it together and the competition takes care of itself.
Families. The distance bothers no child, and the photo tasks are where the youngest players get ahead of everyone. The riddles end up being a joint effort, which is exactly why a group of mixed ages works here.
Frequently Asked Questions
How does the Secrets exploration game work?
Book a date and a link arrives by email. The Loquiz app does the rest. You start it at the first location in Duisburg, and from there your position drives everything — each stop brings a riddle, a puzzle or a photograph to take, and answering it opens the next stop.
Is this a walking tour or a game?
It is both at once. The route through Duisburg is the route a self guided tour would take and you learn the same things, except nothing is narrated — you get riddles instead of commentary, and there is no one at the front with a raised umbrella.
What do we need to bring?
Just a charged phone and comfortable shoes for 3 to 4 km. You get a link when you book and open the game in the Loquiz app at the first stop; nothing to print, nothing to plant beforehand, nothing to pick up anywhere.
How long does it take?
About two hours, covering 3 to 4 km on foot. There is no time limit and no fixed start — you pick a date when booking and then begin whenever suits you on that date, so a slow group simply takes longer.
How many people can play on one ticket?
One ticket covers a group of 1 to 4 people playing on one device, at €19.95 in total. Groups larger than four buy a second ticket, which also lets them play against each other.
Is it hard?
The difficulty is intermediate. The riddles need looking and lateral thinking rather than local knowledge, and nothing is so obscure that a group gets stuck for good.
Is it suitable for children?
Yes. The distance is ordinary walking for them and they are normally first through the photo tasks. Intermediate riddles mean the family works them out together, which is how it is designed.
Do we need to book a date?
No — only a date. The hour you actually begin is yours, and there is nobody waiting: no meeting point, no guide, no group.
What happens if it rains?
You decide when to play and you can pause whenever you like. If a shower comes over, step inside somewhere, wait it out and pick up where you left off — you pause whenever you like and there is no clock running.
Will we actually learn something about Duisburg?
It is the whole design. Every riddle sits on something real — the history of Duisburg, the people in it, the details nobody points out — so you come away with more than a visitor normally does. If a plot appeals more than a route, the other city games in Duisburg have one.

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!
