Ninefold Sudoku: Story Quest

A parcel arrives four days after Nora's mentor disappears. Inside is an atlas with a route that should not exist.

Welcome to Lumen: a city of lantern markets, glasshouse trams and river walks hidden between the pages of its official maps. Join map conservator Nora Vale and a little brass moth named Pip as each Sudoku reveals another clue. Find the missing cartographer, discover who changed the records, and help the city find its way again.
