Starting at Drapers House, 10 York Pl, Leeds LS1 2DS, UK, open the Explorial app and enter the 6-digit game code that you received by text and Viator chat message. The riddles take you through a city centre packed with Victorian ambition and contemporary energy. The first clue leads to the Grand Theatre & Opera House Leeds, a magnificent 1878 Victorian auditorium whose ornate facade and gilded interior have hosted opera, ballet, and theatre for nearly 150 years and remain at the heart of the city's cultural life. From there the app guides you to Leeds Cathedral — St Anne's — a Gothic Revival Catholic cathedral that sits quietly amid the city centre's commercial bustle, its carved stonework and soaring interior offering a moment of calm amid the city's pace. The route then takes you to Winifred, a public sculpture that has become one of Leeds' most talked-about additions — art in the streets of a city that takes its creative reputation seriously. Around 2 hours on foot through the compact city centre. Leeds is a very walkable city with good cafes for a mid-game break.
