Solve a murder in Leiden on this self-guided murder mystery game, a detective trail that turns the historic centre into your crime scene. Following in the footsteps of Sherlock Holmes, you gather evidence at real locations: a coded message near Burcht van Leiden, a photo task at Leiden American Pilgrim Museum, a witness statement that does not match what you saw at Stadhuis Leiden. Every puzzle you solve takes another name off the list of suspects. The game takes about 2 hours and you play at your own pace. One ticket covers a team of 1 to 4 people sharing one phone; larger groups buy extra tickets and can race each other. Choose a start date and time when booking, then begin whenever it suits you - there is no guide to meet and no fixed departure. Stop for lunch, leave the case where it stands and pick it up later. A smartphone with an internet connection is required. Your investigation starts at Stadhuisplein. After booking, you receive an email with your instructions and game link.
