The award ceremony was attended by Croatia's President Kolinda Grabar-Kitarovic and Education Minister Blazenka Divjak, British Ambassador Andrew Dalgleish, and the head of the Institute for Youth Development and Innovativity (IRIM), Nenad Bakic.
Grabar-Kitarovic, the Croatian Makers League sponsor, said Croatia needed a new elementary school education and that IRIM's League project showed that unity concerning education and children's future was possible in Croatia. She said the League was a unique philanthropic project that had expanded to Bosnia and Herzegovina and Serbia.
Divjak said there was a strong need to come out of political trenches and put education before ideology.
Bakic said his project was a symbol of technological development and inclusion which showed that education was the future.
Two competitions were held this year, one physical and one online, with 1,500 pupils participating.
