Explore Mannheim on a self-guided walking tour with puzzles, photo tasks and stories about the Paradeplatz, the palace and the old churches.
You and a phone against Mannheim. Secrets of Mannheim is a self-guided scavenger hunt played on the spot itself, with nobody setting the pace but you.
The game reads your position, so each location arrives with its own riddle, puzzle or photograph to take. None of it can be answered from a screen — what you need is in front of you in Mannheim, in whatever happens to be standing there. You finish knowing a set of things most residents never picked up.
Among the stops: Paradeplatz, Denkmal Karl Ludwig von der Pfalz and Sint-Sebastiaankerk (St. Sebastian's Church). What you are hunting for is rarely at the stop itself but somewhere on the way, in something you would have walked straight past.
Other stops include Jesuitenkerk (Jesuit Church) and Mannheim Palace — enough of them that the group ends up arguing about answers rather than asking what to do next.
A Self-Guided Walking Tour of Mannheim, With Riddles Instead of a Guide
A self-guided tour with the guide replaced by riddles. The route through Mannheim is real, the history is real, and the difference is that you dig it out instead of being handed it — no commentary, no umbrella to follow, nobody held up at the back. Intermediate difficulty: most groups solve most of it, and the rest is a good argument. Riddles, code-breaking, and photographs you would otherwise never have taken.
Planning a Fun Scavenger Hunt in Mannheim?
This is one, and it takes about a minute to set up: book a date, download the Loquiz app and start whenever you are ready. There is nothing to print, nothing to hide in advance and no list to write — the route, the riddles and the photo tasks are already built around Mannheim — 3 to 4 km on foot, about two hours — and one ticket covers a group of up to four on a single phone for €19.95. If you were about to spend an evening making one yourself, this is the version where somebody else did the work.
Who It Suits: Adults, Teams and Families in Mannheim
Adults. Nothing about this resembles a printable list of things to find. It runs at intermediate difficulty, the riddles want things read properly rather than glanced at, and two hours passes without anyone checking their phone for other reasons.
Teams. Nothing to facilitate, nowhere to book, no start time to enforce. One ticket per four colleagues, every group loose in Mannheim on the same route, and a comparison at the end. Several teams at once is what makes it a team scavenger hunt rather than a walk.
Couples and friends. No umbrella to follow, no group to stay with, no fixed pace. Stop where you like, take as long as you like, and finish knowing things about Mannheim that most residents never learned.
Families. Children manage the walking easily and tend to win the photo tasks outright. Because the riddles get solved together, a group spanning three generations still functions as one team.
Frequently Asked Questions
How does the Secrets exploration game work?
It runs in the Loquiz app. After booking you get a link, walk to the starting point in Mannheim and begin. The game reads your location, gives you that spot's riddle, puzzle or photo task, and unlocks the next one when you have it.
Is this a walking tour or a game?
Both, and that is the point. It follows a walking route through Mannheim the way a self-guided walking tour does, and you pick up the history as you go — but instead of a commentary in your ear you get riddles to solve. Nobody walks in front of you holding a sign.
What do we need to bring?
A phone with battery and shoes that handle 3 to 4 km. You get a link when you book and open the game in the Loquiz app when you get there — no printing, no hiding things in advance, no kit to collect from anyone.
How long does it take?
Two hours is typical, over a 3 to 4 km route. There is no clock and no scheduled departure — you fix the day when you book and start whenever you want on it.
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?
It sits at intermediate. What it asks for is attention and lateral thinking rather than local knowledge, and no riddle is obscure enough to end the afternoon.
Is it suitable for children?
Yes. Children manage the 3 to 4 km easily and are usually the quickest at the photo tasks. The riddles are intermediate, so most families work through them together — which is how the game is meant to be played anyway.
Do we need to book a time slot?
No. You choose a date when booking, then start at whatever time you like on that date. There is no meeting point, no guide and no group to join.
What happens if it rains?
Rain is a pause, not a problem. Duck inside, let it pass, and carry on from the stop you were at — nothing is counting down.
Will we actually learn something about Mannheim?
Yes, and not as a side effect. The riddles are made from the history and the characters of Mannheim and from details most people never notice, so the learning is the solving. Anyone who would rather follow a story can take one of the other city games in Mannheim.

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!
