Conexão Férias (or Vacation Connection in English) was a project developed for the city of São Caetano do Sul. It was an activity suggested by the major, to motivate their students to do a scavenger hunt game with important spots in the city. The students received a little book with information about the spots and they scanned a marker that gave them hints about the place to be found. Arriving at the place, they could learn about it and receive the next hint.
The project was made using Zapworks and stayed live during the summer vacation (Dec. 2019 to Feb 2020). In this video you can see a little bit of the gameplay (from 0:45 to 2:38).
