What I am giving here won't be the fastest way to solve a Rubik's cube, you won't need to understand the whole mechanics but neither will you have to refer to anything or need external help after this help of mine of course! This is for those who can solve a bit of the cube, not whole or those who can do it by following a lot of algorithms from somewhere. With this, you will be able to solve the whole cube and only remembering a few easy algorithms.
Rubik's cube remains one of the most interesting and yet simple puzzles ever made. It caught the imagination of the world and still remains one of the elusive ones. Dealing with a Rubik's cube can be very frustrating and so a majority of people don't even try it.
A little more about it- The Rubik's Cube is a 3-D mechanical puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the "Magic Cube", the puzzle was licensed by Rubik to be sold by Ideal Toys in 1980 and won the German Game of the Year special award for Best Puzzle that year. As of January 2009, 350 million cubes have sold worldwide making it the world's top-selling puzzle game. It is widely considered to be the world's best-selling toy.
In a classic Rubik's Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally white, red, blue, orange, green, and yellow). A pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be a solid colour. Similar puzzles have now been produced with various numbers of stickers, not all of them by Rubik. The original 3×3×3 version celebrates its thirtieth anniversary in 2010.
It was also shown in one of the most popular movies- The Pursuit of Happyness. In the 2006 movie The Pursuit of Happyness, Chris Gardner (character played by Will Smith) impresses his future employer by solving a Rubik's Cube. Will Smith accomplished the same trick thirteen years prior in an episode of The Fresh Prince of Bel-Air to impress a college recruiter. And apparently Will Smith can solve it in real life too and there is also a video showing him do that in 55 seconds.
In Bollywood movies too, it has been shown-
- In the 2010 Bollywood movie My Name is Khan, Rizwan Khan played by Bollywood legend shahrukh khan is seen solving Rubik's Cube.
- In the 2010 Bollywood movie 3 Idiots, Rancho (character played by Aamir Khan) is seen roaming around in the College holding a Rubik's cube.
- In the 2010 Bollywood movie Karthik Calling Karthik, Karthik (character played by Farhan Akhtar) is seen solving the Rubik's Cube by his split personality.
As you might have seen, generally anywhere in the movies or ads or Tv shows, whenever they want to show someone as intelligent, they show him solving the Rubik's cube. But it is not so much about intelligence as it is about simple algorithms. Now onto the actual, main part. What I am going to tell you is how to solve a Rubik's cube without any external help. As it is, it is difficult to solve even after getting all the help. Most people would be happy if they can just solve the Rubik's cube without doing things like changing the stickers or dismantling it, and then there are others who are into speedcubing with the world record for solving the fastest being 7.08 seconds!
So what I am giving here is something in between. It won't be the fastest way, you won't need to understand the whole mechanics but neither will you have to refer to anything or need external help after this help of mine of course! This is for those who can solve a bit of the cube, not whole or those who can do it by following a lot of algorithms from somewhere. With this, you will be able to solve the whole cube and only remembering a few easy algorithms.
Here is how to do it -
Here you can see that each side of the cube has a different name:
Front (F), Back (B), Right (R), Left (L), Up (U), Down (D).
These sides are named because of their orientation to you, not because of their color. If you turn the cube upside down, the UP becomes DOWN, and the DOWN becomes UP, so the sides don't retain their names. DOWN is whatever side is pointing to your feet, and UP is always pointing up.
There are only 3 types of turns that are useful: clockwise, counterclockwise ( ' ) and half turn ( 2) . The symbols in parenthesis will be what I use to differentiate between different types of turns.
( & F would mean to make a CLOCKWISE quarter turn of the FRONT face,
L would mean to make a CLOCKWISE quarter turn of the LEFT face & so on)
(& U' would mean to make a COUNTERCLOCKWISE quarter turn of the UPPER face,
L' would mean to make a COUNTERCLOCKWISE quarter turn of the LEFT face & so on)
U2 would mean turning the upper face twice (half turn) ( clockwise or counterclockwise doesn't matter because the end result will be the same- turning 180 degrees)
Step 4 - Getting the 4 corners of the last layer in right place -
This step is to get the 4 last corners in the right place, but not necessarily rotated correctly. For example:
