To achieve this, we designed 2 customized technological gymkhanas through geolocated iPads, one through the Gothic Quarter of Barcelona and the other through the center of Sabadell, with more than 300 participants.The challenge consisted of overcoming the greatest number of challenges and missions of all kinds, exploring the most authentic corners of both cities. From photographic missions where they had to show their most creative side, questions and enigmas about the history and culture of the city or fun interactive mini-games such as digital puzzles, videos or memory games. At the end of the game we were able to take a nice “big family photo” gathering the hundreds of participants.
