Rubik cube solution guide

  1. 1. mStep 1: Step 1 of this method is entirely intuitive. I dont want to burden you with algorithms for thisstep. All you want to do is go from an entirely scrambled cube to selecting a top face, and solving the 4edges of the chosen top face (the edge pieces of a cube have two colors on them). Play around with thecube until you can do this without any problems from any start point. Notice that each edge piece isaligned such that the top face is of the chosen top face color, and the color on the side corresponds tothe color of the center tile on that face. This is called solving the top cross. Step 1 Before Step 1 AfterStep 2: The second step is also intuitive, and just involves solving the 4 corners of the top face.The corner pieces of a cube are the pieces with 3 colors on them. In this second step, you aregoing to intuitively get the corner pieces involving blue into the correct corners (make sure thecolors on these pieces apart from blue line up with the center pieces of the same colors). Thissolves the top face, and forms short Ts down the four sides of the cube. I refer to thecombination of steps 1 and 2 as solving one face to a T. With practice, you should be able to dothis in about a minute or so starting from scratch (dont worry if it initially takes you severalminutes. The important thing is to get familiar with how different cubes move in relation to eachother).
  2. 2. Step 2 AfterStep 3: At this point, turn the cube over, so that your solved side is on the bottom. Thus, bluebecomes the down side of the cube (D). Your aim in this step is to complete solving the secondlayer of the cube by getting the edgepieces of the colors around blue in their right places andorientations. Thus, after the end of step 3, you will have two layers of yellow, orange, white andred (your colors may be different depending on how your cube is colored. I am referring to thecolor scheme on my cube in which green is the color opposite the solved blue side).Now, if any of the second layer edge pieces are already in the correct position and orientation,you dont have to worry about them. But many times, you will find edge pieces that are supposedto go into the second layer in the third layer.In one configuration (option 1), you will find second layer edge pieces that need to be rotatedfrom the right face to the corner of the front and right faces. That is, the piece needs to be rotatedinto place anticlockwise. Step 3 Before, Option 1Notice how, in the picture above, the white and red piece in the middle top of the right faceneeds to be moved anticlockwise to the middle of the edge between the front and right faces. Inthis case, the following sequence of steps will accomplish this: U F U F U R U R.
  3. 3. Step 3 After, Option 1Notice how the white and red face has been moved anticlockwise to its correct location andorientation.In the other configuration (option 2), the edge piece needs to be moved from the top of the frontface to the corner of the front and right faces (so, it requires a clockwise rotation). Notice the redand yellow corner piece in the picture below. Step 3 Before, Option 2Notice how, in the picture above, the yellow and red piece in the middle top of the front faceneeds to be moved clockwise to the middle of the edge between the front and right faces. In thiscase, the following sequence of steps will accomplish this: U R U R U F U F. If you areastute, you will realize that this is essentially the same set of moves as in option 1, just that youstart from move 5 of option 1, and cycle around to move 4 after the end. So, you only have toactually memorize one algorithm for step 3.
  4. 4. Step 3 After, Option 2Notice how the yellow and red face has been moved clockwise to its correct location andorientation.Now, one complication that you might encounter when you are solving this second layer is thatthe edge piece you want in a particular position may be in that position, but may be in the wrongorientation. In other words, for example, the yellow and red edge piece may be at the corner ofthe yellow and red faces, but may be placed such that the yellow side of that edge piece is on thered face and the red side of it is on the yellow face. In that case, there is no simple algorithm toreorient the piece in place. You have to push some other edge piece into its position using one ofthe algorithms above, and this will pop that edge piece to the upper layer, from where it can bemoved down to its correct position and orientation using one of the algorithms above.At the end of step 3, you will have a cube that has one side fully solved (blue in my case), and 4sides solved two-thirds of the way (two layers each of red, yellow, orange and white in my case).Your cube will look like the picture below, assuming you have the same color scheme as me.You dont see the orange and yellow sides, but they are also solved two-thirds of the way justlike the white and red sides in the picture below. The green side is still a mess while the blue side(which is at the bottom) is fully solved (make sure you have not made any mistakes in applyingthe step 3 algorithms by turning the cube over and making sure that the blue side is indeedsolved. If it is not, re-solve it, and then apply the step 3 algorithms more carefully). Step 3 AfterStep 4: In this step, your aim is to solve the upper face (the green face in my case) to a cross.That is, I want to align the edges that involve green such that the green side is on the upper face
  5. 5. of the cube. At the end of this step, you may not have those edge pieces placed correctly, but atleast all their green faces will be on the green side of the cube. If you already have the 4 edgepieces involving green placed in such a way that their green sides are on the upper face, skip step4 and proceed directly to step 5.At the end of step 3, you may find yourself in one of three situations as far as the upper face isconcerned. Step 4 Before, Option 1 Step 4 Before Option 2 Step 4 Before Option 3Ignore the corner pieces and concentrate only on the edge pieces involving green. You mightfind that none of the green sides are on the top face (option 1), or you might find two of them onthe top face on adjacent sides of the cube (option 2), or you might find two of them on the top on
  6. 6. opposite sides of the cube (option 3).If you find yourself facing option 1, it does not matter how you hold the cube. If you face option2, make sure that the two adjacent sides on which the green edges are on the top face are on theback and left. If you face option 3, make sure the green pieces form a bar parallel to the frontface of the cube.From all three options, you can execute the following algorithm to get to the point where all theedge pieces are placed such that their green sides are on the upper face: F R U R U F. Whenyou do this, you will notice that if you start from option 1, you will end up in either option 2 oroption 3 when you execute this algorithm once. If you start from option 2, you will end up inoption 3 after one execution of this algorithm. If you start from option 3, after one execution, youwill be ready to move to step 5. If you want to cut down on one application of the algorithm, youcan apply a modified algorithm from option 2 to skip option 3 and end up with a green cross ontop. That modified algorithm is F U R U R F.Either way, you should now have the following configuration in front of you at the end of step 4(ignore the green corners. You may or may not have them as shown below. All you need is agreen cross on the upper face). Step 4 AfterThe edge pieces involving green may or may not be in the correct positions. We will deal withthat in step 5. If you have blue solved fully, four sides solved two-thirds of the way, and theedges involving green positioned with the green sides on the green face, you are done with step4.Step 5: In step 5, we are going to align the edges of the green face so that they line up with thecolors on the sides of the faces. You may have 1, 2 or 4 of the top edges aligned correctly withcolors on the sides (if you look at the picture above, you can rotate the upper face clockwise by90 degrees to align the green and yellow face). If all 4 edge pieces are aligned correctly, skip step5 and go directly to step 6.If you find only one top edge aligned correctly, make that part of the front face, as shown in thepicture below. You are now going to apply the algorithm below that will move the edge piecefrom the left face to the right face, the one on the right face to the back face, and the one on the
  7. 7. back face to the left face. The piece on the front face does not move. So, it is an anticlockwiserotation ofthe edge pieces skipping the edge on the front face. Step 5 BeforeThe algorithm is: R U R U R U U R. Step 5 AfterSince three of the edge pieces move when this algorithm is applied, if your cube already has twotop edges aligned correctly, you may have to apply the algorithm multiple times to get all theedges aligned correctly. In the first application, you will end up destroying one or both of theoriginal alignments, and then you can rebuild all of them by applying the algorithms a couplemore times. Make sure you understand what changes the algorithm makes (anticlockwiserotation of the edges, skipping the front face), and you will have no trouble figuring out how bestto use it.Step 6: Step 6 is used to position the top corner pieces correctly. At this point, you only have 4unsolved pieces in the cube (at most). These 4 pieces could be at the correct places, but wronglyoriented (in which case, skip to step 7). None of them may be in the right place (note that at thisstage, you can not rotate the upper face because that will causethe edge pieces to get out ofposition), or 1 of them could be in the right place, but the other three are in the wrong corners.If none of them are in their correct corners, you can apply the algorithm holding the cube withany of the sides (that is the faces other than blue and green in my case) as the front face. If one ofthe corner pieces is in the correct corner (dont worry about its orientation), make sure you holdthe cube such that you place that piece in the front upper right corner of the cube (this is the only
  8. 8. corner that is not going to move when youapply this algorithm).The algorithm below causes the front upper left corner piece to move to the back upper rightcorner, the back upper right corner piece to move to the back upper left corner and the backupper left corner piece to move to the front upper left corner. It is an anticlockwise rotation ofthe corner pieces skipping the front upper right corner. You might haveto apply it more thanonce to position all the corners correctly. Once again, understand what the algorithm does, andyou will have no problem figuring out how to use it.The algorithm is: U R U L U R U L.Step 7: Now you have a cube in which all the top corners are positioned correctly, but one ormore of them may be oriented wrongly. If you find that the cube is fully solved at the end of step6 (that is, all the corners oriented themselves correctly while being placed in their correct spots),you are done. Congratulations! Otherwise, you will have to orient the corner pieces.Now, step 7 is a little confusing. Not because the algorithm for it is complicated. Quite on thecontrary: it is a very short algorithm. But throughout step 7, your front face is never changed. So,pick a front face right now. I have picked red in the pictures below. You can pick any, but it isnot going to change as you progress through step 7.Once you have picked a front face, bring a mis-oriented corner piece to the upper front rightposition by rotating the upper face of the cube. The mis-orientation may look like the picturebelow, in which the top color (green) is on the right face. Step 7 Before, Option 1In this case, apply the algorithm below twice to get the green side on the upper face: R D R D.After you do this, you may notice that your cube may look very scrambled. You may find bluepieces floating around, away from the bottom face where they belong. DO NOT PANIC.Between when you begin step 7 and when you complete step 7, you will find all kinds of weirdchanges in the cube that you just have to ignore.Just make sure you get the green side of the corner cube to the upper face, and then rotate theupper face (only the upper face) of the cube to get the next mis-oriented corner piece in the frontupper right corner of the cube. Make sure you continue to keep red (or whatever face you chose
  9. 9. at the beginning of step 7) as the front face. You may then be faced with the following situationpictured below where the green is on the front face. Step 7 Before, Option 2Notice how the cube looks very scrambled. That is because we are in the middle of step 7. Dont worry.Just apply the same algorithm as before (R D R D), but 4 times to get the green side on the upper face.Continue turning the upper face and orienting each top corner piece so that the green is on the upperface. Do not worry about how bad the cube looks in the interim.Once you are done with all four corners, and all of them are oriented properly, you may find that yourcube looks as below: Almost done!Now, all you have to do is rotate the upper and down faces of the cube a couple of times to lineup all the colors, and you will have yourself a fully solved cube, as shown below:
  10. 10. Fully done!That is all there is to it! Two algorithms in step 3 (one of which is actually a variation of theother), and one algorithm each in steps 4 (two if you want to use a shortcut), 5, 6 and 7. A totalof 6 or 7 algorithms, none of which are longer than 8 steps. That is all it takes to solve the cube! Itold you it was easy. Try it and let me know how it works out. Good luck!
