Secrets of Basel hands you the streets themselves as a puzzle. It is a self-guided scavenger hunt on your own phone, no guide, no group, no departure time.
The game follows your position around Basel and each stop brings its own riddle, puzzle or photo task. You cannot look any of it up: what is standing in front of you is the source. By the last stop you have picked up more about the place than a guided tour would have told you.
The route takes in Basel Marktplatz, Peterskirche Square and University of Basel Entrance, and the walking between them is where most of the finding happens, what you need is out there in front of you, never on the screen.
Other stops include Heuberg Street and Spalenberg Alley, enough of them that the group ends up arguing about answers rather than asking what to do next.
The Walking Tour of Basel Where Nobody Talks at You
A self-guided tour with the guide replaced by riddles. The route through Basel 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.
Had great fun playing secrets of Haarlem!

Looking for a Scavenger Hunt to Do in Basel?
Right here. Organising it means booking, opening the link in your phone's browser and then starting when it suits you. Nothing to print, nothing to plant beforehand, no clues to invent: the route through Basel 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.
An Outdoor Scavenger Hunt That Works for Any Group in Basel
Teams. One ticket covers four people, so a department divides straight into groups running the identical route through Basel. 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.
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.
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 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 Basel that would surprise a local.
Frequently Asked Questions
How does the Secrets exploration game work?
You book, get a link by email and need no app. At the starting point in Basel you open the game in your phone's browser. It is GPS-based: it knows where you are, and each location holds a riddle, a puzzle or a photo task. Solve one and the next location unlocks.
Is this a walking tour or a game?
Both, and that is the point. It follows a walking route through Basel 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 your phone's browser 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?
€19.95 buys one ticket, one phone and one to four people around it. Larger groups split across two tickets and end up competing, which most of them prefer.
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. You choose no date or time when booking: the ticket is valid for 12 months and you start whenever you like. 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 Basel?
It is the whole design. Every riddle sits on something real, the history of Basel, 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 Basel have one.

Wir (Mein Mann, unsere 9-jährige Tochter und ich) haben heute ganz spontan das Spiel "Moordmysterie Düsseldorf" gebucht und gespielt. Die Buchung verlief schnell und reibungslos.
Es hat super viel Spaß gemacht! Die Story, die Rätsel, das Konzept, die Route, die Gestaltung der App... richtig gut!!!
Das Spiel würde ich vor allem Familien mit Kindern empfehlen.
Für Erwachsene waren die Rätsel (meiner Meinung nach) zu einfach. Aber trotzdem wegen der schönen Route durch Düsseldorf, der Story, den lustigen Anweisungen zwischendurch eine schöne Aktion, die man zusammen machen kann.

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.
