The competition in solving the cubic puzzle, invented 50 years ago by Hungarian sculptor and professor of architecture, Ernő Rubik, was organised by the Speedcubing Croatia association, and it brought together competitors from Croatia, Bosnia and Herzegovina, Slovenia, Serbia, Hungary, Ukraine, Poland, Germany and the Netherlands.
The winner Berčič solved the cube in the finals with an average time of 8.68 seconds.
David Vujasić, a 25-year-old psychologist, holds the national record in speedcubing, his fastest single solve taking 5.55 seconds. Most of the competitors at the Ogulin event were school-goers, the youngest competitor was 7 and the oldest 65.
