'The Cube has his own voice'

I arrive at the Szepilona Bisztro, on a leafy road on the "Buda" side of Budapest, holding a Rubik's Cube and searching for the man who had created it almost 50 years ago. I feel unworthy to have lunch with Emo Rubik, not the least reason of which is because the Cube I am holding has never been solved.

Rubik arrives punctually. He's been coming to this restaurant since the late 1960s, when he was a graduate student, before he had invented one of the world's most successful puzzles-a cube with 43 quintillion combinations, only one of which is correct.

At that time, Rubik was living in his family's apartment on a grand avenue on the "Pest" side of the city. He was a professor of architecture, but his room was "like a child's pocket, full of marbles and treasures".

In an attempt to help students understand three-dimensional problems, he tried to build a set of cubes that stayed together but could also move independently. He painted each side a different colour. But after he had twisted it, he realised that he could not easily return it to its original state.

"It was a more difficult task to find a system to solve it than it had been to create the thing itself/' he says. In the end, it took him a month. And solving it gave him a "happy feeling of freedom'', he said at the time. The Rubik's Cube was born, and to date more than 450 million have been sold, the craze reaching its peak in the early 1980s.

Rubik was 29 when he "discovered" the Cube in 1974. By 1979, Rubik had sold 300,000. From there, it spread across the world, with some 100 Rubik's Cubes being sold in only three years.

"I can't imagine there being a higher type for it than there had been in the '80s," he says. He motions to my Cube. Rubik comforts me with a Japanese slogan from the 1980s, coined for a game: "a minute to learn and a lifetime to master".
