Rubiks Cube - A mind twisting puzzle

“Come on Let’s Twist Again” – Rubiks Cube
Got bored? Want some mind twisting puzzle? Why not try some Rubiks Cube. Well, it may look very simple, this colored square thing that has many face but do you know that it is considered as the world's best-selling toy and it's known as an International game. A standard ‘3x3x3’ Rubik’s Cube has 6 colored sides, 21 pieces and 54 outer surfaces. This means there are more than 43 quintillion possible configurations, or 43,252,003,274,489,856,000 to be exact. But there is only one solution. The World Cube Association has organized many competitions and kept the official world record since 2003. But more than that, Rubiks cube was first used as a teaching tool to help students understand 3D Objects way back in the mid 1970's. Ernő Rubik who is a Hungarian architect, inventor and professor invented the cube to show his classes how 3D objects move and to teach structural design problems like "How could the blocks move independently without falling apart?" Back then he didn't realize he had just created the bestselling puzzle game in history. The first time he twisted the cube for a few times he notice that it is even harder to twist the blocks back in order and it took him a whole month to figure out a right solution. Originally, it is called "Magic Cube" in 1975 but then it was renamed after its inventor "Rubiks Cube" in 1980. But nowadays, people (including me) see the Rubiks Cube as a game, pastime. Many variations of the original cube were created, for example the V-Cube 7 or the "Pocket Cube". Different competitions are held worldwide and the world record was set by an Australian , who was able to solve the cube in 5.66 seconds. Other alternative challenges these days have been held including blind-folded solving, underwater solving, solving the cube with the feet, solving the cube using just one hand and the fewest moves solving.
At first, it was really difficult for me to solve it, most people solve the cube layer by layer. This is a simple way for the human mind to approach the problem, but it is useless for speed cubing. No matter how good you are, you will use more than 100 moves. Solving it does not require any attention to orienting those faces correctly. Normally, I focus on the center faces of each color and follow some patterns. In Rubik's cubers' parlance, a memorised sequence of moves which has a desired effect on the cube is called an algorithm that means a list of well-defined instructions for performing a task from a given initial state, through well-defined successive states, to a desired end-state. Each method of solving the Rubik's Cube employs its own set of algorithms, together with descriptions of what effect the algorithm has, and when it can be used to bring the cube closer to being solved. The basic problem with the layer method is a big one, and it's obvious once you realize it. When you have completed the first layer, you can donothing without breaking it up. So you break it, do something useful, and then restore it. Break it, do something, restore it. Again and again. But the good thing is you will do something useful all the time which will make you busy.
