City tour through a treasure hunt

We decided to make the usual city tour as a treasure hunt in order to involve also the local community in the activity. Teams were formed by Erasmus students, Italian students, and also local inhabitants. Each team had to find the quickest way to visit most of the interest points in the city and collect the highest score to win the prize (a mobile phone offered by the university). The activity involved also some computer science students, who provided QR codes for the quizzes.
