So, you don't know how to solve a Rubik's Cube? Learn how to solve a Rubik's Cube easily and quickly with these steps.



First of all, why is solving all sides of this little twisty cube almost impossible? Because the Rubik's Cube can be twisted and turned into 43 quintillion possible positions. Among all of them is one special position that is solved.



Get to Know your CubeEdit

The PiecesEdit

  • Pieces with 2 stickers are referred to as edge pieces. There are 12 of them.
  • Pieces with 3 stickers are referred to as corner pieces. There are 8 of them.
  • Pieces with only 1 sticker are referred to as center pieces. There are 6 of them. Center pieces can only be turned, not moved and represent the color of their side when the side, layer or cube is solved. Center pieces cannot be swapped: white will always be opposite yellow, orange will always be opposite red, and green will always be opposite blue.

NotationEdit

Notate



Each side of the cube is represented by a letter. The side that faces you is the F side (F meaning front), the side that faces across from you is the B side (B meaning back), and the U, L, D, and R sides are pretty much self-explanatory: U=up, L=left, D=down, R=right.

The moves of the cube are also represented by letters. A capital letter (e.g: R) would mean to turn that face 1/4 clockwise as though you're facing it. A capital letter with an i after it (e.g: Ri). That 'i" just means inverse. So it would mean to turn that face 1/4 counterclockwise as though you're facing it. This is pretty much the same for F Fi U Ui L Li D Di B Bi R Ri. A "2" after a letter mean to turn that face 180º. Because it's a 180º turn, it doesn't matter where to go clockwise or counterclockwise (anti-clockwise).

First LayerEdit

The Daisy CrossEdit

Daisycross



Your current goal is to put 4 white edges around the yellow center (or whichever center is opposite white), which looks like a daisy. The non-white colors of the daisy edges are also lined up with their centers.



Find an edge piece with white in it. Now twist the cube so that the piece is in the bottom layer if not already:

Ri-daisy



turning Ri will bring the piece to the bottom layer

F-daisy



turning F will bring it to the bottom layer.



If the piece is already in the bottom layer, you can skip that last step. If it is oriented or positioned incorrectly in the top layer however, hold the cube so that it is in the right face, and do Ri to reduce this to one of the above cases.



D-daisy

Now look at the non-white portion of the edge piece you located and turn the down face until the non-white color is matched up with its center, like so:


F2-daisy



When you get this, hold the cube so that it is in the F face and do F2, bring it to the top layer. 



When you have solved 1 daisy "petal", choose another white edge and repeat the process. When done, you will have your daisy.



The White CrossEdit

Once you have a daisy, it is very simple to get your edges to the bottom layer without swapping them.

1-daisy-edge



Choose a daisy "petal" to start with. A daisy petal is any edge piece with white in it. Hold the cube so that the piece in the front face and then do F2. Now choose another petal and repeat. When done for a total of 4 times, you will have a white cross:

The-cross

The White SideEdit

To begin, find a corner piece with a white side.



If the corner is in the bottom layer, you'll have 3 possible corner orientations:



Corner-whiteCorner-2Corner-3



Hold the cube so that the corner is in the bottom right of the front face and do the algorithm Ri Di R D. Repeat it until the corner is in the correct place and is oriented correctly.



If the corner is in the top layer but in the wrong position or orientation, hold the cube so that the unsolved corner is in the top right of the front face, and do Ri Di R D. The corner will then move itself to the bottom layer. Do this with all remaining corners and you should be done with the first layer:

The-first-layer

Middle LayerEdit

Hold the cube so that the solved white side is on the bottom. Now find a middle layer edge piece (an edge piece without yellow on it).

A middle layer edge in the top layer will have 2 colors: 1 face color, which is facing you, and 1 crown color, which is facing the sky. 


Middle-layer-lined-up



Line up a middle layer edge's face with its center using U moves.



Looking at the right and left faces of the cube, 1 of them is the same color as the middle layer edge's crown.



Middle-layer-lined-up-1



If this is the right face, preform the algorithm U R Ui Ri Ui Fi U F.



Middle-layer-lined-up-2



If this is the left face, preform the algorithm Ui Li U L U F Ui Fi.



If the middle layer edge piece is in the middle layer but in the wrong position or flipped the wrong way, replace it with different edge from the top layer. To do that, hold the cube so that the unsolved middle layer edge piece is in the center right of the front face and then preform the algorithm that we use to bring a middle layer edge piece to the middle layer: U R Ui Ri Ui Fi U F. The unsolved middle layer edge will then move to the top layer and it can be done the normal way.



First2layers



Once you have done this with all 4 middle layer edges, you should be done with the first 2 layers.



Last LayerEdit

When you go to the last layer, keep in mind that it uses very complicated algorithms, because you do not want to mess up your first two layers. Also, for this layer the pictures will be only of the top view of the cube:

You will also be able to tell if your cube is unsolvable. White means that the last layer color does not matter. A yellow line means that yellow is not facing up. Hold the cube so that the yellow center is on the top (U) face.



Yellow CrossEdit

After you have completed your first 2 layers, you will have 4 possible edge orientations. We are ignoring the orientations of the corners now. If 1 or 3 edges face up, your cube is unsolvable, which can happen if you peel off stickers or take apart your cube, then reassemble the cube randomly or glue the stickers back in a random order. If you see this, take apart your cube and then reassemble it solved.



Yellowcenter



If you see an isolated yellow center piece (no edge pieces on the same side that face up), hold the cube with the yellow center on top and do the algorithm F U R Ui Ri Fi.



Yellowline



If you see a line (two facing-up yellows that are across from each other) hold the cube so that the line is horizontal and on the top layer and do the same algorithm as for the other cases but with one change: F R U Ri Ui Fi. This change is to avoid breaking the line on the very first turn.



Yellowl



If you see a "J" (two facing-up yellows that are adjacent to each other) hold the cube so that the J is on the top left corner of the U face and do F U R Ui Ri Fi.



Yellowcross



If you see a cross (4 yellow edges facing up), you can proceed to orienting the corners.



Orientation of the Last Layer CornersEdit

You will have either 0, 1, 2, or 4 correctly oriented corners. When you look at the last layer, look at the corners: asign each correctly oriented corner a value of 0, a corner that needs to be rotated clockwise 1 and a corner that needs to be rotated anti-clockwise -1. They should all add up to 3, 0 or -3, if it is anything else your cube is unsolvable.



0corners

  • No correctly oriented corner (Cross): Have a yellow left corner facing left. Do R U Ri U R U2 Ri.

1corner

  • 1 correctly oriented corner (Fish): Position the cube so that the fish's "head" (the correctly oriented corner) is on the bottom left corner. Do R U Ri U R U2 Ri.

2corners

  • 2 correctly oriented corners (Spaceship): Don't worry about the position of the 2 corners. Have a yellow left corner with yellow facing you. Do R U Ri U R U2 Ri.

4corners

  • 4 correctly oriented corners (Yellow Side): Skip this step and move on to permutation. 



Permutation of the Last LayerEdit

Turn the U face until 2 corners are in the correct place. If no adjacent corners match, 2 corners that are across from each other will be on BC or on AD as shown below. If 2 corners match that are adjacent to each other. they need to be on the B face, or AB.

Lastlayerabcd



It doesn't matter where to start when no adjacent corners match, since 2 matching corners will already be diagonal AD or BC. Do the algorithm Ri F Ri B2 R Fi Ri B2 R2 Ui. When 2 adjacent corners match, put them in the B face and do the algorithm again. Now all 4 corners will be in the correct place.



Once you have 4 solved corners, you will have either 3 or 4 unsolved edges. 



Efg



If you have 3 unsolved edges, hold the cube so that the solved edge is on the back. 



Efgh



If all 4 edges are incorrect, do either algorithm below once.



Now determine which direction the 3 pieces need to move and do the correct algorithm below:



  • Cycle EFG/EFGH Clockwise: F2 U L Ri F2 Li R U F2
  • Cycle EFG/EFGH Anti-Clockwise: F2 Ui L Ri F2 Li R Ui F2



Unsolve-1Unsolve-2



If you've gotten through all of this and still 1 corner or 1 edge is oriented incorrectly, or 2 edges or 2 corners need to be swapped, and everything else is correct, it means your cube is unsolvable.



Solved
