Explore Mainz on a self-guided walking tour with puzzles, photo tasks and stories about the Markt, the cathedral and the Gutenberg Museum.
An outdoor scavenger hunt through Mainz, run from your own phone and finished whenever you decide you are finished. Secrets of Mainz turns the streets themselves into the game.
It works off GPS, so the game knows where you are and hands over that location's riddle, puzzle or photograph. All of it points outward, at Mainz rather than at the phone. The history arrives sideways, through the puzzles, which is why it stays with you.
Mainz Cathedral (Mainzer Dom), Eisenturm and "Gardetrommler" der Mainzer Prinzengarde are on the route, and the stretches between them matter just as much: everything you are looking for is in plain sight and ignored by everyone else.
Marktbrunnen and Römerschiff-Nachbildung are on the list too, and the habit of looking up sets in on its own.
A Self-Guided Tour of Mainz That Asks the Questions
The shape of a walking tour, the mechanics of a puzzle. You cover a genuine route through Mainz and pick up what happened there, except nothing is narrated at you and nobody is waiting for stragglers. Walk, look, work it out. It sits at intermediate, which means a normal group gets through most of it and argues about what is left. Riddles, code-breaking, and a camera roll you did not expect.
Looking for a Scavenger Hunt to Do in Mainz?
This is one, already built. Setting it up is a date and a link: book, download the Loquiz app, begin when you feel like it. Nothing gets printed, nothing gets hidden beforehand and no list gets written, because the route through Mainz, the riddles and the photo tasks all exist — about two hours over 3 to 4 km on foot. One ticket is €19.95 and covers up to four people on one phone. It is the same evening you were going to spend writing clues, spent walking instead.
An Outdoor Scavenger Hunt That Works for Any Group in Mainz
Adults. As a scavenger hunt for adults it has real bite — this is not a printable list of things to spot. The difficulty is intermediate, the riddles reward looking at what is in front of you, and the two hours hold up for a group that came to be entertained.
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 Mainz that would surprise a local.
Teams. One ticket covers four people, so a department divides straight into groups running the identical route through Mainz. 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 Mainz, 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?
Both, deliberately. On distance and route it is a walking tour of Mainz; on content it is a puzzle. The history arrives through the riddles rather than through a guide, and there is nobody to follow.
What do we need to bring?
A charged phone and shoes you can walk 3 to 4 km in. You get a link when you book and open the game in the Loquiz app at the starting point — there is nothing to print, nothing to hide in advance and no equipment to collect.
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?
Between one and four people share a single phone on one €19.95 ticket. Beyond four, take a second ticket — two groups on the same route can race each other, which is the better way to do it anyway.
Is it hard?
Intermediate. Observation and sideways thinking do the work; you do not need to know the city, and nothing on the route is built to stop you permanently.
Is it suitable for children?
Yes — the 3 to 4 km is no obstacle and the photo tasks are where younger players get ahead. The riddles sit at intermediate, so families tend to solve them as a group, which is the intended way round.
Do we need to book a time slot?
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 Mainz?
That is the point of this one. The riddles are built on the history, the characters and the odd details of Mainz, so you finish knowing things most visitors never find out. If you would rather have a story than a tour, look at the other city games in Mainz instead.

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!
