The HacKIDhon (open source children’s marathon) tournaments, a registered trademark of the BG, is a “clever innovation” event involving hundreds of primary, secondary and high school students throughout the country. The competitions are held every year on 3rd or 4th of May. The aim of the competition is to solve a problem with the knowledge and skills acquired throughout the education of coding, three-dimensional design, Smart device design / coding and entrepreneurship trainings. The collaborated schools participate in a team of three people in primary, secondary and high school categories. Students develop a product that will be a solution to a specific problem by using software, hardware and design skills. The problems are delivered in the morning time, and students are given a time until the afternoon. The biggest goal of the HacKIDhon tournaments and the other informatics festivals is to improve and demonstrate the acquired skills about “production with informatics” of the students to gain self-confidence.
