Australian Feliks Zemdegs took his second win at the Rubik´s Cube World Championship held in Sao Paulo.

Zemdegs completed the traditional 3x3x3 Rubik´s Cube in a staggering 5.695 seconds, narrowly missing world record holder Collin Burns, an American, who completed it in 5.25.

“The competition was really, really awesome, well-run, the venue was really nice, all the people were really nice. The win was also really nice as well,” Zemdegs told Reuters after collecting his prizes. “Because I won last time, I was sort of less nervous this time because I had already won one so that sort of helped a bit.”

The championship has a total of 17 different Rubik’s Cube competitions. Players are timed to see who can complete the puzzle the fastest.

Most people are familiar with the standard 3x3x3 Rubik’s cube, but they might be surprised to know in the world of competitive speedcubing, cubers compete with cubes sized 2x2x2 all the way up to 7x7x7.

But the main event is the standard 3x3x3 Rubik’s Cube, a popular toy that was first invented 41 years ago by Hungarian professor Erno Rubik as a way to challenge his architecture students.

And while most people have fiddled with the toy, few have probably ever been able to complete it — without removing the coloured stickers, of course.

The 3x3x3 With Feet competition might be one of the most interesting, but even more impressive is the blindfolded competitors who must memorize the cubes before solving them with their eyes covered.

Contenders in the 3x3x3 Multiple Blindfolded challenge complete a series of puzzles one after the other without ever removing their blindfolds – a remarkable feat by any standard.

According to the official rules, the competitors must declare how many cubes they intend to complete within the first 15 minutes of time allotted.

According to Brazil’s best, Gabriel Dechichi, who completed the 3x3x3 cube in 10.050 seconds, the host nation is growing in the sedentary sport with some super-speedy cubers.

Prize money goes to the winners of each of the 17 events with 20 percent of the pool going to the winner of the 3x3x3 Cube event — the main event in the cubing world.

The 2015 Cube World Championship reunited the world’s meanest “speedcubers” in São Paulo, Brazil, on July 17-19, 2015. It was the 8th World Championship, and the first in South America.
