You set off from a square where the cobblestones keep secrets and the Loire watches, patient and wide. A notification pings, the Loquiz app opens, and the city becomes a story: shopfronts slide into clues, statues deliver lines, and narrow alleys tuck away riddles. The plot pulls you through Nantes’ changing neighborhoods—old merchant quarters, modern riverside blocks, and the odd industrial relic that remembers the city’s shipbuilding days.

You set off from a square where the cobblestones keep secrets and the Loire watches, patient and wide. A notification pings, the Loquiz app opens, and the city becomes a story: shopfronts slide into clues, statues deliver lines, and narrow alleys tuck away riddles. The plot pulls you through Nantes’ changing neighborhoods—old merchant quarters, modern riverside blocks, and the odd industrial relic that remembers the city’s shipbuilding days.
Nantes grew as a river port and industrial hub; its streets are carved by commerce and reinvention. This self-guided Sherlock Holmes game layers fiction on top of real streets, using local architecture and public squares as puzzle stages. Expect to read plaques, pore over façades and follow directions that make you look twice at familiar corners. Culture here leans playful: street art on Île de Nantes and hidden arcades nod to a city that likes to surprise.
Practically, the game is low-impact and accessible—aim for about two hours of walking across mostly flat, paved streets. You’ll need a charged smartphone, a steady internet connection or local data, and comfortable shoes. Watch traffic when solving clues at intersections and respect private property while hunting for answers. The experience is social: teams of up to four per device work well, and you can stop and restart where you like.
Treat it like a walking scavenger hunt that teaches local history while testing your observation skills. Time your play for morning light to read inscriptions easily, or after lunch when cafés nearby offer a quick break between clues.
