Get to know the cube
A standard Rubik’s cube is made of 6 sides or faces. (Up, Front, Right, Left, Down, Back) Each face is a different solid color when the Rubik’s cube is solved. Each face has 3 vertical layer and 3 horizontal columns. Each layer and column can be turned independently.
Each face is represented by a letter. For example, U represents the face on top of the cube.
The Rubik’s cube is made up of 26 smaller pieces. 6 center pieces, 8 corner pieces, and 12 edge pieces. The cube is solved when each of the smaller cubes is in the correct spot.
A turn is made by rotating one of the faces of the Rubik’s cube. Turning the face 90° is called a quarter turn. A 180° turn is a half turn. A turn can either be done clockwise or counterclockwise.
Clockwise turns are designated by the face letter. (Ex. F means rotate the front face clockwise 90°) Counter clockwise turns are represented by adding an apostrophe next to the letter. (Ex. F’ means rotate the front face counter clockwise 90°) Half turns are represented by the number 2 next to the face letter. (Ex. F2 means rotate the front face 180°)
Two Layer Turns
Turning two layers at once is designated by a lowercase letter. (Ex. f means rotate the front face and the layer underneath clockwise simultaneously)
Middle turns are made when only the middle slice is moved. There are three middle slices.
Multiple turns made together in order is called an algorithm. Algorithms are used to move the pieces of the Rubik’s cubes. Algorithms are described by a list of Turns. R U R’ U’ is an example of a simple algorithm. Many algorithms are used throughout these tutorials
Holding the Cube
Holding the cube properly before performing an algorithm is important for the algorithm to work. You hold the cube with your right hand on the right face, and you left hand on the left face. You look down on the cube at a slight angle so you should see the front and top face at the same time.
At times during this tutorial you will be instructed to hold the cube with a particular center piece on the top and in the front. There are two different types of visuals used to help portray what the cube should look like.
