Cevko (Tubey) opens the door to children into a water world of adventures: quite literally, because it replaces the classical structure of a website with the exploration of mysterious houses as a part of the urban infrastructure which invites them to explore. Each of thehouses hides interesting content enriched with videos, animations, audio and games. When a child enters the room he or she intuitively slides through educational sets and interactively, from different perspectives, learns about the story of water and how to protect water sources with Cevko.

With its website, Cevko responds to children as they can choose a topic in a user-friendly and simple way by entering a mysterious house in the city and, in it, explore the rich multimedia content on the importance of drinking water and its preservation. ENKI d.o.o., the communication agency that developed the website, integrates children into the water story intuitively; everything uses responsive design adapted to different displays. The user experience is optimised on a computer screen, however, due to the video and animations.

Among others, Cevko.si won the Netko Award for the best children's online content in 2015.
