What to expect
Delft becomes an interactive treasure hunt. Follow a walking route past famous landmarks and hidden gems, and at every stop solve a puzzle you find in the surroundings — the clue is around you, not on a screen. Sightseeing, a continuous story and a light brain-teaser rolled into one, played at your own pace straight from your phone's browser. No app, no account, no live guide: just open the link and start exploring.
