The Brainfinity competition has 3 stages

Brainfinity problems

Each 25th of the month

Brainfinity problems are posted on the platform on the 25th of each month. By successfully solving the problems, the teams qualify for the following stage – the challenge. Each problem is solved online and the deadline for sending answers is the 15th of the following month.

Brainfinity challenge

In late March

Three tasks are published on the homepage for the teams to solve online from any location they choose: from home, at school, in a café, etc. They have 2 hours to solve these 3 tasks, after which they send their answers here.


After the challenge

In the finals, the teams have 2 hours and 30 minutes to solve 2 tasks, submit the answers and the presentation for the jury, and prepare for the presentation which is scored. The teams will solve the problems in separate rooms using computers and tablets.

Team registration

Each team has 4 members. The members are elementary school students attending years 5 through 8 and high school students, and the team enters the category of the oldest team member. Once you have formed a team, you have to find a teacher who will support and mentor it.

Then, think of a team name, email and logo, make a team photo, and REGISTER.

Try to be as original as possible, as it will affect the jury’s perception of your team. If you register a team name that already exists, you will be assigned a number, as well. The teams are officially registered once they are on this platform.

Brainfinity problems – rules:

In the first stage of the competition, the teams have to solve the Brainfinity problem online.
To do this, they need to register first.

Afterwards, on the 25th of each month until February, a Brainfinity problem is posted on this platform for the teams to solve by the 15th of the following month. Expired Brainfinity problems cannot be solved subsequently.

Therefore, the sooner the teams register, the better chances they have to qualify for the next round, as they have more problems to solve.

Brainfinity challenge – rules:

In order to take part in this challenge, you will need a computer with an internet connection and a room where your team can work without being disturbed. You can use multiple computers, tablets, mobile phones and other devices – any technology you have at your disposal.

Stay alert, as we will post the Brainfinity 2020 tasks in late March on our homepage. From that moment on, you will have 2 hours to solve the tasks and send the answers to the jury.

Solving tasks online and submitting answers

Together with your teammates, choose a location where you will do the tasks. But remember:

If you fail to complete the tasks within this time frame, you will have an opportunity to take part in the Brainfinity competition the following year.

Once you have solved the problem, you need to prepare your answers before sending them to the jury. Bear in mind that the jury also evaluates the form in which you submit the answers. All the answers combined must not exceed 5 MB.

Once you have prepared your answers, go to the portal page and upload your files.

Publishing challenge results and qualifying for the finals

The answers are reviewed by the jury members who mark them from 0 to 20.

The teams are ranked for each class based on the sum of all marks. The top five teams in each class qualify for the finals, and the list of finalists is published within two days following the challenge.

Brainfinity finals – rules:

The finalists have more than a month to prepare for the finals.

On the day of finals, the teams arrive with their mentors an hour before the start and are presented with all the necessary details.

The teams have separate rooms, computers and tablets necessary to solve the 2 final Brainfinity tasks that are published at a particular time on the website homepage.

Final contest in Belgrade

All the teams are presented with the same two tasks, but in different rooms. Their mentors cannot keep them company, however, they, and anyone else who wishes to, can follow their team via live stream. The finals are a bit more demanding, so step up your organizational skills.

After the two and a half hours, the teams are required to present their solutions.

The teams are joined by their teachers and can use a projection screen for their presentation. After the presentations, the jury withdraws, marks each team and decides on the winners.

Winner announcement and award ceremony

At the end of the competition, the jury announces the winner and provides a detailed explanation of their decision. This is followed by the official award ceremony.

The best team receives tablets, medals and trophies, as well as numerous other benefits, while the teachers get a free one-year membership at the Institute for Contemporary Education, where they can gain skills and experience regarding problem solving.
