History of the Rubik's Cube
The Rubik's Cube was invented in 1974 by Ernő Rubik, a Hungarian sculptor and professor of architecture. He wanted to create a 3-D model that could demonstrate three-dimensional movement to his students. He used wooden blocks, paper clips, rubber bands, and glue to make his first prototype. He called it the "Magic Cube".
He soon realized that his invention was not only a teaching tool but also a puzzle. He spent weeks trying to solve it himself before he succeeded. He applied for a patent in Hungary in 1975 and later licensed his puzzle to be sold by various companies around the world. The puzzle was renamed "Rubik's Cube" in 1980 by Ideal Toy Corp., one of its distributors.
The Rubik's Cube became an instant hit and a cultural icon. It won several awards for best toy and best puzzle. It inspired books, movies, art works, competitions, and research. It sold over 450 million units worldwide as of 2021, making it the best-selling toy of all time. It also holds several Guinness World Records for fastest solves by humans and machines. The Rubik's Cube is still widely popular today among people of all ages and backgrounds.

Methods for Solving the Rubik's Cube
There are many methods for solving the Rubik's Cube, each with its own steps, algorithms, and notation. Some methods are easier to learn but slower to execute, while others are harder to learn but faster to execute. Some methods are more suitable for beginners, while others are more suitable for experts. Here are some of the most common methods for solving the Rubik's Cube:
The Beginner's Method: This is the simplest and most widely used method for solving the Rubik's Cube. It involves solving the cube layer by layer, starting from the bottom (white) layer, then the middle layer, and finally the top (yellow) layer. It requires memorizing only a few algorithms and can be learned in less than an hour. However, it is not very efficient and can take up to two minutes to solve the cube.
The CFOP Method: This is the most popular and fastest method for solving the Rubik's Cube among speedcubers (people who compete to solve the cube as fast as possible). It stands for Cross, First Two Layers (F2L), Orientation of Last Layer (OLL), and Permutation of Last Layer (PLL). It involves solving the cross on the bottom layer first, then inserting four pairs of edge and corner pieces to complete the first two layers, then orienting all the pieces on the last layer so that they have the same color on top, and finally permuting them so that they are in their correct positions. It requires memorizing about 80 algorithms and can take less than 10 seconds to solve the cube.
The Roux Method: This is an alternative method for solving the Rubik's Cube that is based on block building rather than layer by layer. It involves solving two opposite corners and their adjacent edges on the bottom layer first, then solving two large blocks on either side of the cube, then orienting and permuting the remaining four edges on the top layer. It requires memorizing about 40 algorithms and can take less than 15 seconds to solve the cube.
The Petrus Method: This is another alternative method for solving the Rubik's Cube that is based on block building rather than layer by layer. It involves solving a 2x2x2 block on the bottom layer first, then expanding it to a 2x2x3 block, then solving the remaining four edges on the top layer, then orienting and permuting the last layer. It requires memorizing about 20 algorithms and can take less than 20 seconds to solve the cube.
The ZZ Method: This is a method for solving the Rubik's Cube that is based on edge orientation rather than block building or layer by layer. It involves orienting all the edges on the cube so that they have the same color on the front or back face, then solving the cross and the first two layers simultaneously, then solving the last layer using only two algorithms. It requires memorizing about 10 algorithms and can take less than 25 seconds to solve the cube.
These are just some of the many methods for solving the Rubik's Cube that exist. You can find more online or in books or videos. You can also try to invent your own method or combine different methods to suit your style and preference.

The current world record for solving the 3x3x3 Rubik's Cube with feet is 16.96 seconds, set by Daniel Rose-Levine from the USA in 2019.
How many moves does it take to solve the Rubik's Cube?
The minimum number of moves required to solve any scrambled 3x3x3 Rubik's Cube is called God's number. It has been proven that God's number is 20, meaning that any cube can be solved in 20 moves or less. However, this does not mean that it is easy to find these moves. The average number of moves required to solve the cube using a human method is around 50 to 60.
How many combinations does the Rubik's Cube have?
The total number of possible combinations or permutations of the 3x3x3 Rubik's Cube is 43,252,003,274,489,856,000. This is a very large number that is hard to imagine. To put it in perspective, if you had one cube for every permutation and stacked them on top of each other, they would reach about 261 light years high. That is more than twice the distance from the Sun to the nearest star (Proxima Centauri).
Is it possible to solve the Rubik's Cube without looking?
Yes, it is possible to solve the Rubik's Cube without looking at it. This is called blindfolded solving or blindsolving. It involves memorizing the state of the cube using a system of letters or images, then executing a series of moves based on that memory. Blindfolded solving is a popular category in cubing competitions and requires a lot of practice and skill.
Is it possible to solve the Rubik's Cube by luck?
No, it is not possible to solve the Rubik's Cube by luck or by randomly twisting and turning it. The probability of solving the cube by chance is extremely low: about one in 43 quintillion. That means that if you tried one move per second, it would take you more than a trillion years to solve the cube by luck. Therefore, it is much better to learn a method and use your brain than to rely on luck.
