Scientists says there are more than 43 quadrillion combination in Rubik's Cube, but it can actually be solved in less than 20 moves.

To be more precise, the scientists says there are 43,252,003,274,489,856,000 combination in Rubik's Cube. This is 43 quadrillion 252 quintillion 3 trillion 274 billion 489 million 856 thousand combination.

Researchers solve Rubik's Cube in 20 moves

A group of international scientists were trying to find how many moves will it take to solve the Rubik's Cube. The goal was to find the minimum number of moves needed to solve the three-dimensional geometric puzzle. The finding says it needs either 20 or less moves to solve Rubik's Cube. It took the researchers 30 years to find the answer.

"Every cubic puzzle can be solved in 20 moves or less," say the mathematicians, including Morley Davidson who was one of the leading participant in the investigation that deciphered the code. Davidson is from the Kent University, located in Ohio State.

In fact, the majority of "minimum combinations" took between 15-19 moves. The researchers used Google Supercomputers to find the answer. In only few weeks the computers provided the answer that it takes between 15-19 moves to solve Rubik's Cube.

Every Rubik's Cube has 26 small cubes. This puzzle, which has become one of the most famous puzzles of the world, has been invented by a Hungarian inventor Erno Rubik in 1974.
