Explore Trier on a self-guided city tour from the Kornmarkt past the market square, old palaces and Roman remains.
A scavenger hunt that uses the streets themselves as its board: Secrets of Trier runs on your own phone, starts when you say so, and takes exactly as long as you let it.
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 Trier, in whatever happens to be standing there. You finish knowing a set of things most residents never picked up.
Karl Marx House, Saint George's Fountain and Nachlassgericht Trier come up along the way. The stretches between the stops are where most of the looking gets done, at things that are hidden only by being ordinary.
Red House and Dreikönigenhaus are on the list too, and the habit of looking up sets in on its own.
The Walking Tour of Trier Where Nobody Talks at You
A self-guided tour with the guide replaced by riddles. The route through Trier 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.
Want to Plan a Fun Scavenger Hunt in Trier?
Right here. Organising it means booking a date, download the Loquiz app and then starting when it suits you. Nothing to print, nothing to plant beforehand, no clues to invent: the route through Trier and everything on it is already built, about two hours across 3 to 4 km. One ticket covers up to four people on one phone for €19.95. The evening you were going to spend writing riddles is now free.
Who It Suits: Adults, Teams and Families in Trier
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 Trier 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.
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.
Couples and friends. A self-guided walking tour that does not involve following an umbrella. You set the pace, stop where you want, and end up knowing things about Trier that most people who live there do not.
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 Trier, 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, and that is the point. It follows a walking route through Trier 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?
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?
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?
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?
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 don't book a time. You can start whenever you like within 12 months of purchase. There is no meeting point, no guide and no group to join.
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 Trier?
Yes, and not as a side effect. The riddles are made from the history and the characters of Trier 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 Trier.

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!
