When and where?
Saturday, 20 December 2025, in Zagreb.
Who can apply?
All pupils and students aged 15 to 19!
Applications open on 28 October!
Teams participating in the competition will have the following task:
Develop an innovative technical solution that addresses an important social or environmental problem of your choice, highlighting how your solution can contribute to the community and create a lasting, meaningful impact.
Teams choose the problem they will tackle before the competition and develop their idea/solution.
On the competition day, each team will work together on the solution and prepare a 5 minute presentation. All team members must take part in developing the idea and creating the presentation, and each member will have their own role.
In their presentation, teams will explain the social or environmental problem they chose, present their solution, and demonstrate how it can be used and applied in the real world.
Teams will then pitch their idea before the judging panel in a 5 minute pitch, followed by questions from the judges.
