After a year of pandemic breaks, it was time again.

Fourteen competitors have for two days tried to break each other in ten different branches of memory.

The one who collects the most points in the decathlon can call himself "Sweden's best memory 2021".

- In the last branch, you should remember a deck of cards as soon as possible, says Idriz Zogaj, who works as a civil engineer on a daily basis.

In the other branches, participants must memorize numbers, pictures, faces, names and binary numbers.

- Everyone basically uses the same technology, which is based on turning abstract information into images.

Then you place the pictures in a memorial palace, says Idriz Zogaj.

High school teacher Martin Nilsson also defended his Swedish Championship gold this championship, but Idriz Zogaj won the silver medal.
