The game "Monsters in the City" is a treasure hunt through Rapperswil. It was developed for kids who are guided by Professor Proof and his crow via tablet.
They'll be led from stage to stage with the help of GPS. Their task is to find cute monsters in Rapperswil and solve puzzles. In the end, the kids rescue the professor from a tight spot.
Two to seven kids can play on one tablet. As a companion, you can join for free.
