Our task was to promote the VELUX Indoor Generation advertising campaign. The concept phase included the development of several gamification ideas, which were later presented to VELUX. The quiz game was chosen. The user gets interesting questions about indoor generation. After selecting the correct answer, the interface showed feedback and the space on the screen became brighter, thus bringing light through knowledge into the house. As far as the user answers everything correctly, he gets a chance to win the main prize from VELUX.
