The Catalan Energy Institute of the Generalitat de Catalunya programmed different online activities. One of them was the Hello Watty game, a didactic proposal that was already used at schools and children, and which had to be turned into a video game. We take care of “saving Wattys” from home, distinguishing efficient actions from non-efficient ones. An example of the use of gamification for learning and outreach.
