Start investigating your case on the Kornmarkt, with a route that runs through Germany's oldest city to the Porta Nigra.

This is a detective game on foot, played at whatever pace suits your group: crack codes, take photographs, and question digital characters whose statements do not always align. Every puzzle you get right cuts the suspect list down again.

You'll share one phone per group, with larger groups splitting into more teams.

Play the Sherlock Holmes City Game, a self-guided tour of the city. Navigate the city to unlock tasks. Meet characters who will help you, but only if you solve their puzzles. Enjoy funny photo challenges, track down culprits, and work towards solving the murder of Balthasar.

Explore the city at your own pace with this flexible game. Play anytime, anywhere, and with anyone you choose.
