How can you finish a rubix cube




















The Easiest Method We will learn this step by step:. Keep scrolling down! Discover the Rubik's Cube Spend some time playing with the puzzle to familiarize with it before you read this solution tutorial and see how far you can get without help. Fixed Center Pieces Notice that no matter what kind of face rotation you do, the center pieces always stay in the same position.

Edges And Corners Beside the fixed center pieces the cube is composed of 8 corner pieces with 3 stickers and 12 edge pieces with two stickers. Too Many Cases There are so many possible configurations over 43 quintillion that it would be impossible to solve it by randomly turning the faces until it's all done.

The Strategy It's hard not to break the solved pieces while fixing new ones. The Letters In The Algorithms We've marked the six faces of the cube with the initials of their names. F' Front face counterclockwise turn. R2 Double rotation on the Right face. Click the buttons to see the animated rotations in action. And now we're prepared to learn the solution!

Solve the white edges We start by solving the white edge pieces. Here are a few examples that require a few extra moves. Press the Play button to animate the rotations. Solve the white corners The white edges are solved and we have to fix the white corners to complete the first face. If you have difficulties solving the white corners, here's an easy trick you can always apply, you just have to memorize a short algorithm and repeat it until the piece is solved: R' D' R D Bring the corner below the spot where it belongs Front-Right-Down position highlighted with grey and repeat the algorithm above until the white corner pops into its place oriented correctly.

At the end of this step your cube should have a solid white face. Second Layer F2L Now that we've finished the white face , let's turn the cube upside down because we don't need to see the solved side anymore. Wrong orientation When there's no edge piece to insert into the middle layer you will have to execute the algorithm twice to pop the piece out in the first step.

For example, when the edge is on its place but turned incorrectly:. The Top Cross In the fourth step we want to form a yellow cross on the top of the cube. Make sure you reorient the cube in your hands after the first stage because the "L"-shape will be upside down. Make sure the yellow edges are located on the left and back positions as illustrated. Line — Perform the algorithm once, holding the line horizontally and you're done.

Cross — The cross is complete, you can go to the next level! Swap Last Layer Edges We have the cross on the top but the sides of the yellow edges don't match the side colors yet. Orient last layer corners In the last step every piece is where it's supposed to be, but the yellow corners are oriented wrong. Watch the video or the animation below that demonstrates examples of how to use this move.

Summary Here are all moves together to help you practice. White Face Cross, then corners. In such cases, displace them is-matched middle-layer edge piece by performing the left or right trigger. There should now be an edge piece in the top layer without a yellow sticker. Solve for it as described above. The goal of this step is to create a yellow cross on the upward-pointing face of the cube. This entire step hinges on the following algorithm:. At this point, the top face of your cube should resemble a yellow cross.

For this step, you will use the following algorithm:. Begin by inspecting the top face of your cube. How many corners have yellow stickers on top? If you have zero or two, hold the cube so a yellow sticker is in the upper right hand corner of the face in your left hand, i. Rotate that face until the fish is pointing down and to the left, like so:. You might have to orient the fish and perform the algorithm one last time. Once you have, the yellow face will be entirely solved.

The above algorithm swaps corners A and B. Note that the eighth step of the algorithm undoes the seventh. Now that the first two layers are done, we need to do the top layer. The first step of the two-look OLL, which is the easier but slower method , is to orient the last layer edge pieces.

To do this, there are three algorithms. You might recognize these from the beginner-method stage in which you create the white cross. This one has seven different algorithms depending on the configuration of your top face. These algorithms are organized by the shape they make on the upper face , so practice this stage until each algorithm feels natural when you see the corresponding cube arrangement. There are 21 potential arrangements of your cube at this stage , which means that you have 21 different algorithms to learn.

Once again, there are two different methods: two-look and one-look PLL. Two-Look PLL. This version is great for beginners, but those who want to be competitive will need to work on mastering one-look PLL. Next, permute the edges. Practice these algorithms a lot so they become second nature to you. By the end of this step, the edges of the back, down, and front faces, as well as the corners of the down, back, and left faces and the left and right centers, will be solved.

How you approach this step will depend on the configuration of your cube. The creator of this method suggests focusing first on solving a 1x2x2 block by putting together a corner-edge pair and then adding in the missing edge before solving for the last corner and edge. This lets you focus on just two elements rather than all of them at once. Algorithms depend on your unique configuration, so practice matching the configuration with the correct algorithm until it comes naturally to you.

This stage is one of the most difficult in the Roux Method. There are 48 potential ways your cube could be arranged here. How you solve the cube will depend on the arrangement, so work through this collection of algorithms with lots of different variations to get the hang of them all.

With so much of the cube finished, on average, most people need fewer than 15 moves to solve the cube from here. The first step of this stage is to orient the edges. You do this only by moving the middle and up faces , saving valuable movement since the other faces are already oriented correctly. Finally, solve the center and edges of the middle face.

There are only three possible cases for this stage , which eliminates some of the necessary memorization, though there is potential for optimization.

If solved in this way, you can finish the cube by rotating only the L, R, and U faces rather than all of them. To accomplish this, build two 1x2x3 blocks on either side of the line you made in the EOLine stage. Again, now that the edges are oriented, you only need to rotate the L, R, and U faces to complete the cube.

As you might have guessed, the final step is to solve the last layer. The two-look system has 20 potential algorithms to be learned, while the one-look system has a whopping potential algorithms. The only way to get better is to practice , so keep working at it until you can feel your speed increasing as you go.

If you have all four already facing upwards, you don't need this step. When you eventually get the desired position, there are two slightly different variations of it. For this, we need to look at the front of the cube. The yellow corner facing the front can be in two positions: Either facing the front, or facing the right.

In the first image, it is facing the front. This shows you have Sune. To solve it, just do the above algorithm one more time, and you should have oriented all of the top layer. Sune and antisune. Here, we're looking at the colours that aren't solved. There are 21 different cases for the top layer, but we only need a couple of algorithms to solve them all. The first thing we want to find is headlights.

Only 2 of the cases don't have any headlights one of them is if you skip this step, and the cube is already solved. For the one case without headlights, just perform the algorithm below from any angle. This is a better case because when you do the next step, the cube will be solved already. Headlights are fairly simple to spot.

Looking at the image, we can see on the right hand side that the orange edge has a green corner on either side of it. That is a set of headlights. The left hand side has two different colours on either side, so that is not a set of headlights. It is very important to note that a full bar a blue edge has a blue corner on either side of it, so all three pieces are blue is also seen as a set of headlights. This is only seen in one case of the 21 though, so you won't see it often.

Headlights : two corners having the same colour on one side. You want to hold the cube so that the set of headlights is facing away from you do the required number of U moves so that the headlights aren't on the front, left or right. Then, do the following algorithm:. There are 5 different positions your cube can be in now, one of which could be solved.

The rest of them have all four corners solved, so do the required amount of U moves so that every corner is in its right place. If you don't have a solved bar, do the same algorithm from any angle. This will leave you with a solved bar, so you can do the above.

How to Solve The Rubik's Cube If you're reading this, you're probably holding a cube in your hand and already feeling bad about yourself for needing to look up the solution.

Notation If you're still reading, congratulations on not being put off by the time requirements! These are: U — Refers to a clockwise quarter turn of the upper face. Step 1: The Cross The cross is the first step in the actual solution of the puzzle.

If they are adjacent, hold the cube so that the two solved pieces are facing the front and left of the cube shown in the left picture , then perform: R' U R U' R' If the two matching edges are opposite one another, hold the cube so that they are on the left and right faces shown in the right picture and perform the following algorithm to swap the one in the back and in the front: R2 L2 U2 R2 L2 Your cross is now solved!
