The event was held at Johannes Kepler University Linz for the first time since 2019. A total of 47 teams, each consisting of four to five students from secondary level 2 (in two different age categories of junior and senior) had two hours to try and solve as many tricky mathematical problems as possible. In order to master the tasks, teams had to work together, resulting often in heads spinning and lively heated discussions.

At the end of the two hours, the team from the Gymnasium und Realgymnasium Kollegium Aloisianum Linz emerged as the winners in the junior category. They also took the nationwide victory having solved 28 tasks. The team from the Realgymnasium Benediktinerstift Lambach won the senior category. During the awards ceremony, all of participating teams were warmly applauded and presented with a certificate in recognition of their outstanding efforts over the past few hours. The top three teams in each category were singled out in recognition and rewarded with attractive prizes. The JKU would like to congratulate all of the winning teams and participants in the 2023 Náboj competition!

We would also like to especially thank all of the sponsors and volunteers who helped to organize and make this unforgettable event happen for over 200 students. The next competition is scheduled for April 2024 and we hope to once again experience a memorable turnout.
