According to Reuters, “inspired by the success of Pokemon Go, a Belgian primary school headmaster has developed an online game for people to search for books instead of cartoon monsters, attracting tens of thousands of players in weeks.

While with Pokemon Go, players use a mobile device’s GPS and camera to track virtual creatures around town, Aveline Gregoire’s version is played through a Facebook group called “Chasseurs de livres” (“Book hunters”).

Players post pictures and hints about where they have hidden a book and others go to hunt them down. Once someone has finished reading a book, they “release” it back into the wild.
