Frequently asked questions
Where does the quest start and finish?
It starts at Kornmarkt in Heidelberg's old town and finishes at Karlsplatz. In between you pass stops such as the Heiliggeistkirche, the Jesuitenkirche, the University Library, the Brückenaffe, the Alte Brücke, a castle viewpoint and the Karlstor.
Does the quest cover Heidelberg's old town and university?
Yes. The story casts you as a newly accepted student at Germany's oldest university, and the route runs through the old town via the Universitätsbibliothek, the Jesuitenkirche, the Marstallhof and quiet courtyards, with puzzles set in the places in front of you.
How long does it take and how far is the walk?
Most players take a little over two hours, puzzles and walking included, and cover about 2.9 km. You can pause at any point and continue later, so there is no need to finish in one go.
Can we play as a group, and do we need to book a time?
Yes, one ticket covers the whole group playing together on a phone. There is no set start time and no guide to meet, so you can begin whenever you arrive at Kornmarkt. No attraction tickets are needed for the stops on the route.
So what’s the deal with this game?
You’re on a hunt to uncover a secret student society hidden in Heidelberg’s old town. Each clue pulls you through narrow streets, old university spots, and quiet courtyards until you figure out the mystery.
Who’s this good for?
Pretty much anyone who likes a fun challenge: friends out for something different, couples on a date, or travelers who’d rather explore on their own instead of joining a big tour group.
How long does it take?
About an hour to an hour and a half. You’ll walk roughly 3 km (around 2 miles)—just enough to feel like you’ve really explored without getting tired.
Does Heidelberg Secrets include a university tour?
It is an outdoor, app-guided puzzle route inspired by Heidelberg’s old town and university setting. It is not an official university tour or admission ticket.
