We are extremely sorry that the Náboj competition could not take place on Friday 13th March 2020 due to the COVID-19 outbreak. The international team has, therefore, made the decision to hold it online on 11th December instead. We hope to have Náboj 2021 in person again.

If you have any questions, please contact us via the email address info-gb@math.naboj.org.

The Competition

See current information for details about Náboj Online!

Náboj is a competition designed for teams of five high school students that represent their schools. The whole competition takes 120 minutes during which the teams are trying to solve as many given problems as possible.

Náboj is not just a direct application of the knowledge the students already have. The tasks require a certain amount of inventiveness and ingenuity.
