Intimidating for many, but exciting for others, the Rubik's cube is a great way to work your grey matter. Below are the steps to solve a Rubiks cube-Step 1: First choose a centerpiece of any color (say white) and then make a white cross by bringing all the four edge pieces adjacent to the white center. The majority of these will be CFOP algorithms, and some will be used in other methods such as Petrus, ZZ and Roux. Simply hold your cube so that both blue pieces are in the exact same position as shown in the image and perform the algorithm. Step 1: Make a White Cross. This is called the "reduction method" and requires us to effectively convert the 4 by 4 into a slightly distorted 3 by 3 cube. They are used when all the corners are permuted and there are 3 edges to permute in a triangular fashion. The notation of the Rubiks Cube applies other twisty cubes but there are additional notations because of the deep turns and inner slice turns. Is there a way to explain why such algorithms work? Find the four pieces that make up the center and start by matching two of them to make a bar. What is a Rubik's Cube algorithm? A special notation is used to describe which face needs to be rotated in which direction. The most common way to express a Rubiks Cube algorithm is using Basic Notation, which is depicted below. Note-Centerpieces are always at their original position only. A single clockwise face rotation of 90 degrees will be referred to by its letter. The only potential hangup is that there are no "fixed" centers to guide you for each face. After matching all the layers, the cube will look like this-, Step 3: Set corners of the bottom layer by first matching the correct corner matching its desired color. Luckily one of the edge pieces (the red-white piece) is already in place and just needs to be turned to the left. However, this innocuous looking puzzle is not as simple as it seems.
