Hunt for "Leibniz's legacy" at the Herrenhausen Gardens with Actionbound.

Rainer Künnecke plays Gottfried Wilhelm Leibniz

To commemorate the 375th birthday of Gottfried Wilhelm Leibniz (*July 1, 1646), an interactive Leibniz Actionbound tour entitled "In Search of Leibniz's Legacy" was developed. As of summer 2022, the Leibniz tour will also be available in English.

Discover Leibniz's legacy

Follow in the footsteps of the polymath by completing thirteen tasks at thirteen locations in the “Grosser Garten“. Playfully explore the various mathematical, technical, philosophical, and cultural aspects of Leibniz’s work and life at the Hannoverian court. Finally, discover "Leibniz's legacy" and download instructions for a surprising experiment.

Riddles and quizzes

The interactive tour features three Leibniz films in which Gottfried Wilhelm Leibniz speaks at historical locations, as well as four audio narrations on Guelph history, metaphysics, justice, and philosophy. It also offers additional information, solution pages, exciting puzzles and quizzes, and directions to the respective location.

Digital treasure hunt

The game is suitable for inquisitive players (14 years and older), school classes or families with children aged 14 years and older. It takes about an hour to complete the digital treasure hunt through the “Grosser Garten“. The game is free of charge (plus admission to the Herrenhausen Gardens).

What is Actionbound?

Actionbound is a simple digital app that engages people in a playful way, gets them moving, and helps them discover and learn new things in a fun way. While the tour is similar to a classic scavenger hunt or geocaching, the experience is enhanced by additional media such as video and audio clips, quiz questions, and the players' own creative contributions.
