The Story:

The secretive Order of the Rosy Cross is looking for new members. In order to prove your worth, you must solve their ancient mystery and uncover the identity of one of their historic members, known to you only as A Secret Sender. In this outdoor escape game, explore Golden Age Amsterdam and search the history and architecture for clues to the cryptic puzzles. Only the best can solve the mystery in time. Do you have what it takes?

What happens if it rains?

Teambuilding continues! We will provide umbrellas and ponchos in case of rain. Hot chocolate stops on route are absolutely allowed, but many teambuilding groups tend to be too competitive for that!

Where is it?

The game starts and ends at Mystery City HQ, Zwanenburgwal 178, just next to the Waterlooplein. The route covers approximately 3km and passes by five key sites in the city.
