A 3×3 Rubik’s cube is a three-dimensional object with 6 faces, 12 edges, and 8 corners. The cube has three types of pieces on each face.
Pieces labeled 1- These are corner pieces. They have three colours on them. They move during the course of a solve.
Pieces labeled 2- These are edge pieces. They have two colours on them. They move during the course of a solve.
Piece labeled 3- This is a centre piece. This has only one colour on it. This does not move during the course of a solve.
IMPORTANT- An edge piece can only go to the spot of an edge piece and not a corner or centre. The same applies for corners and centres.
(in the illustrations, gray squares don’t matter)
In algorithms, we use letters to denote faces and which way they should turn. Each face can be turned clockwise or counterclockwise.
Front face= F/Fi
If there is an i next to the letter, the face is turned counterclockwise, and if there is no i, the face is turned clockwise.
We are assuming the standard colour scheme, which means that white is opposite yellow, blue is opposite green, and red is opposite orange. If white is on the front face, then yellow is on the back face, green is on the top face, blue is on the bottom face, red is on the left face and orange is on the right face
Now let’s hurry up and get solving!
Step 0: scramble your cube
Step 1: solve the white cross
Hold the cube with the white centre piece on the top face.
Find an edge piece with white and some other colour on it. I’ll take the white/red piece. Align the piece directly under its desired spot. Once you have done that, you can have one of two cases.
If you have the case above, execute the algorithm Di, Li, F, L to put the edge piece into its desired spot. If you have the case below, where the red side of the edge piece lines up with the red centre, do F, F.
After solving the edge piece, make sure that both colours of the edge piece match up with the adjacent centres.
Repeat with all 4 edges of the white cross.
Step 2 : solve the white corners
After solving the cross, hold the cube with the cross on the top face and look for a white corner on the bottom layer. Once you find it, align it under its spot. Your cube should look like this –
Now that you are all set, execute the algorithm the algorithm Ri, Di, R, D as many times as needed to solve the corner.
If your corner is in the top face but in the wrong spot, execute the algorithm Ri, Di, R, D to get it into the bottom layer.
Repeat with all the white corners.
Step 3: solve the middle layer
Turn the cube over so that white is on the bottom face and then look for an edge piece that belongs in the middle layer that is in the top layer. Once you have found it, turn the top layer until that edge piece forms an upside down T shape. Once you have that, you can have one of two cases. I’ll use the red/green edge piece. In the figures below the green line on the top indicates that the other side of the edge piece is green. The green line on the side indicates that thet side has the green centre.
If you have the case above, execute the algorithm U, R, Ui, Ri, Ui, Fi, U, F
If you have the case below, execute the algorithm Ui, Li, U, L, U, F, Ui, F
If you have an edge piece that is in the middle layer and you want to take it out put it on the left side then execute the second algorithm.
Step 4 : Orient the yellow layer
Part one: get the yellow cross
At this point, you should have the white layer on the bottom, and the yellow face should be in one of these four states –
If you have case 1 or case 2, execute the algorithm F, U, R, Ui, Ri, Fi in the position shown with white on the bottom face. For case 1 you have to execute the algorithm twice.
For case 3 execute the algorithm F, R, U, Ri, Ui, Fi in the position shown with white on the bottom face.
For case 4, move on to part 2.
Part 2: get all the yellow on top
Now you can have one of these cases
1 :one corner
2 :2 corners
3 :no corners4 :all corners
For cases 1 and 2 execute the algorithm R, U, Ri, U, R, U, U, Ri in the position shown with white on the bottom.
For case 3 execute the algorithm mentioned above with red on the front face, yellow on the top face, and white on the bottom face.
For case 4, move on to step 5.
Step 5: permute the yellow layer
Now, you can either have the yellow layer solved, or it can be unsolved. If it is solved, turn the yellow layer until the whole cube is solved. If it is not solved, then you need to permute the last layer, or put all the pieces in their designated spot.
Part one: permute the corners
For this part, look at the corners of the last layer. You can have one of three cases.
For case 1, hold the solved corners in the back and yellow on the top and execute the algorithm Ri, F, Ri, B, B, R, Fi, Ri, B, B, R, R, Ui.
For case 2, hold it with yellow on the top and do the algorithm above twice.
For case 3, move on to part two.
Part 2: permute the edges
Now you can have one of two cases –
For case 1, execute the algorithm F, F, U, Ri, L, F, F, Li, R, Ui, F, F to get case 2.
If you have case 2, there two possibilities you can have.
If you have case 1, execute the algorithm F, F, U, Ri, L, F, F, Li, R, Ui, F, F with the solved edge in the back and yellow on top.
If you have case 2, execute the algorithm F, F, Ui, Ri, L, F, F, Li, R, U, F, F with the solved edge in the back and yellow on top.
If your cube is not solved then turn the top layer until the cube is solved.
