At first glance, the cube seems deceptively simple, featuring nine colored squares on each side. In its starting state, each side has a uniform color — red, green, yellow, orange, blue, or white. To solve the puzzle, you must twist the cubes so that eventually each side returns to its original color: The challenge is the astounding number of potential variations — more than 43 quintillion of them. To master the cube, you must learn a sequence of movements that can be performed in successive order — the subject of several best-selling books as well as online tutorials.
And the evolution of the cube — from a three-by-three-by-three shape to larger four-by-four-by-four and five-by-five-by-five ones — offers different complicated mathematical principles of group theory. Sitting on the patio of his home in the hills of Budapest, Rubik, now 76, fiddled with a cube as he recalled its "discovery" and accidental success. After creating the cube, he explained, he was faced with a second challenge: how to solve it. At the time, he had no idea if his cube could even be put back into place, let alone how fast — and it took him a full month to solve his own puzzle.
It was fiendishly difficult "to find your way back, or to find your target — just to solve it as a combinatorical problem,'' he said. His resume includes stints as a professor, architect, designer, editor and, now, writer. It took several years before the cube was actually released worldwide, a total of 4 between patent receipt and release.
It had to be changed slightly as the West had different regulations in regards to packaging and safety specifications. In the same year, David Singmaster published the first layer-by-layer method, a method which is still used by many puzzlers and beginner speedcubers even today. The cube today has sold over 3 times that figure, making it the best-selling toy of all time.
The victor was Minh Thai , an American teenager, who solved the cube in It still remained on the shelves and still sold incredibly well, but the hype that originated back in its starting years had pretty much died off.
The cube did make occasional appearances in the news, however, such as the Masterpiece Cube that was created in by Diamond Cutters Int. The Fridrich method also known as CFOP , an acronym for the stages of the puzzle is regarded today as the best speedcubing method, and the world record single and average times have been held by Fridrich solvers for many years, despite Fridrich herself estimating that the method would not be efficient for consistent times under 13 seconds. This was the first official organisation that would be responsible for the running of official speedcubing competitions and monitoring of national and international achievements.
The WCA has helped grow speedcubing and has taken the hobby to many new countries. The WCA is today recognised as the official speedcubing association and any potential World Records must be set under WCA regulations and delegation before they are recognised.
In this year, the second World Championship took place. Dan Knight was the victor this time, winning with a time of
