Baltic Olympiad in Informatics

The Baltic Olympiad in Informatics (BOI) is an annual informatics olympiad for the countries of Northern Europe: Denmark, Estonia, Finland, Germany, Iceland, Latvia, Lithuania, Norway, Poland and Sweden.

The first edition was held in Tartu, Estonia, in 1995; it has run every spring since, hosted in turn by the participating countries — in 2026 in Espoo, Finland.

Unlike every other international olympiad, each country fields six contestants rather than four. Ukraine takes part as a guest country: the six best contestants of the final stage of the Ukrainian Olympiad in Informatics are invited.

To qualify to the Olympiad, you need to participate in the Ukrainian Olympiad in Informatics.
