From the 24-th to the 29-th of April 2025, the Baltic Olympiad in Informatics (BOI 2025) was held in Toruń, Poland. The competition brought together 78 participants from 12 countries.

The Baltic Olympiad in Informatics (BOI) is an annual informatics competition for countries bordering the Baltic Sea: Denmark, Estonia, Finland, Germany, Iceland, Latvia, Lithuania, Norway, Poland, and Sweden. This year, two guest countries—Ukraine and Israel—also took part. Unlike other international olympiads in informatics, each participating country in the BOI is represented by six high school students.
