Frequently asked questions
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.
Could this work as a date?
Absolutely. You can wander old streets together, solve puzzles side by side, and maybe grab a drink near the river when you’re done.
What cool spots will we see?
Expect pretty squares, hidden corners of the university, church courtyards, and great castle views you might miss on a regular walk.
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.
Is this experience self-guided?
Yes. The Questo app guides you from clue to clue, with no guide or fixed start time. You can begin when it suits you and pause along the way.
How many accesses does our group need?
Classic quests sell access per device and player. Each person who wants to solve clues on their own phone needs their own access.
