Rubik’s Cube – The Rubik’s Cube was invented by Hungarian architect Ern ̋o Rubik in 1974). His original motivation for developing the cube was actually a curiosity about architectural configurations in space.
- The Cube is an imitation of life itself –or even an improvement on life. The problems of puzzles are very near the problems of life, our whole life is solving puzzles. If you are hungry, you have to find something to eat. But everyday problems are very mixed–they’re not clear. The Cube’s problem depends just on you. You can solve it independently. But to find happiness in life, you’re not independent. That’s the only big difference. –Ern ̋o Rubik
A Rubik’s Cube starts off scrambled and is solved when all of the squares on each face are of the same color. Since its international launch in 1980 there have been approximately 350 million Rubik’s Cubes sold. Today, about one out of every seven people alive have used a Rubik’s Cube.
There are more than 43 quintillion possible scrambles and only one solution for the cube! Actually, there are 43,252,003,274,489,856,000 possibilities.
Any scramble can be solved in 20 moves or less. This is called “God’s Number”.
