![]() Once all of the corner pieces are placed, simply shift the yellow-facing layer 1-2 times, as needed, until the cube is fully solved. Once you have found it, turn the cube around so that the corner piece has its white face facing either right or left. If the yellow side contains half of a cross, rotate the cube around such that the cross is pointed to the right, facing you. Goals Edge Orientation Making the cross on the bottom layer. In our case, flip the cube so that the yellow center is on the top face. Flip over the cube (white is now at the bottom and yellow at the top) You should find there are 0, 2, or 4 pieces (of the white cross) facing up. Solving Rubik The Last Layer The last layer is solved on the top face. This algorithm will flip the edge so that the white part is facing up repeat this for each edge until you have a white cross on top. In doing this, we also need to ensure the other colors of the four white edge pieces line up with the right centerpieces in the rest of the Cube. This is your guide to solving a Rubik’s cube (Graphic: NationalWorld/Kim Mogg) Hold your cube so that one of the edges to flip is facing you, then apply this algorithm: F, R’, D’, R, F2. Once you have made the yellow cross, you will need to put yellow border pieces in their final position, in order to match the colors of the side center pieces. Our next objective is to reach what is called a yellow cross in the upper part of the upper part, without breaking any of the work that we did in the lower two layers. So once you start rotating, you have to rotate it 180 degrees to get back to. ![]() ![]() (Note: If you are having problems disassembling your cube by popping an edge piece then here is a video that will help.To solve the next step, you need to perform a few algorithms, or spin patterns, which lead to the specific cube position. Instead of rotating around the faces or corners, this one rotates around the edges. Their yellow stickers show to the sides, but not to the top. Let's get started.įor an anatomy lesson of the cube, and an overview of the 5-step solution have a look at this introductory video. 3.3 Turn Yellow Corners (make the whole upper side yellow) Now there are presumably 2 or 3 or 4 corners not in right orientation. Sequences listed above, understanding how they work, and how to use them to solve the cube. The focus here will be on learning these four types of move However, in this basic solution I do hope to give you a feel for why commutators are useful, so in steps 4 and 5 I will discuss how these four move sequences were built. This lecture gives you the necessary foundations to build your own move sequences for a variety of other puzzles. Step 1: Solving the white cross If a white sticker is flipped, hold the yellow center on the U face and the flipped edge on the F face To move a white sticker. I won't go into any more details on commutators in this section, but if you want to learn more about commutators see Lecture 13 of the course notes. Each of the corners can also be rotated into one of 3 orientations, so there are 38 possible orientations for each positional arrangement. The main point here is that the four move sequences had to be created, and commutators were a natural form to make them since a lot is known about commutators. If each of the 8 corners could be put in any of the 8 corner locations there would be 87654321 8 possible ways to arrange them. Such as cycling three corners in the opposite direction. The use of brackets above is to draw your attention to the structure of the sequence, all these move sequences have the same form: $\alpha \beta \alpha^ = $, which helps when you want to apply the inverse of one of the sequences above. However, some will benefit from a walk-through, so over the next few pages we'll go through the solution and I'll show you how and when to use these sequences. ![]() In which case, a video like this one would suffice to demonstrate how to solve the cube. For most puzzles on this site I would list basic move sequences like the ones below and stop there, leaving it to reader to use them to solve the puzzle. Move sequences you'll be able to build your own move sequences and solve a variety of other puzzles.įor reference, below are the four types of move sequences we'll use to solve the cube ( pdf). If you learn these four types of move sequences you'll be able to solve the cube from any configuration. flipping a pair of edge pieces (for orienting edges).cycling 3 edge pieces (for permuting edges).twisting a pair of corner pieces in opposite directions (for orienting corners).cycling 3 corner pieces (for permuting corners).It can be solved using only four types of move sequences: It may be surprising to learn that very little memorization is required to solve Rubik's Cube.
