EXAMPLE: If you want the insert the green-orange edge, and the green is facing upwards, while the orange is on the front, line up the orange on the edge with the orange center, and do the correct algorithm to insert it. If you look on the cube, each color has SEVEN pieces of its own. As in, the the color on the edge that's above the center piece should matches the center piece's color. Step 1: Spotting the Centers An important part of the solving of any hard twisty puzzle, is spotting the center. If they are switched (The edge piece on the dslice is on the right and the piece in the uslice is on the left) then just turn the dslice until your cube looks like the diagrams. If the middle layer edge is on the top layer, rotate U until it's matched with an adjacent center sticker. two adjacent edges in the position in the diagrams. An easy way to identify a middle layer edge is to look for edge pieces that have no yellow stickers on it. How Do I Prevent This Mistake From Happening Again? Make the sure edge you're trying to insert lines up correctly. Part 3: Middle Layer Edges Notice that the middle layer consists of just four edge pieces that need to be solved. Now What? You inserted the edge correctly this time, because you positioned it correctly, and did the right algorithm. So doing the algorithm again took the piece back out. Ive noticed that the most commonly given algorithm for flipping the UF and UB edge is this: M U M U M U2 M U M U M U2. I've noticed that the most commonly given algorithm for flipping the UF and UB edge is this: M' U M' U M' U2 M U M U M U2 But I was fooling around and found this one: M' U M' U M' U M' U2 M' U M' U M' U M' I think it might be faster because there are no M moves, which are awkward for me to perform. Why? Remember, it takes out the piece already in position, and that piece was your flipped edge. How Do You Take It Back Out To Try Again?: You did this by repeating the algorithm on an incorrect edge. Position the yellow corners of the Rubiks Cube. Scribd is the worlds largest social reading and publishing site. You should have positioned it the other way, and done the other algorithm. Position the yellow corners of the Rubiks Cube - Read online for free. What Should Have Been Done: There are 2 algorithms for inserting edges during this step. Your Mistake: You positioned the edge piece incorrectly before performing the algorithms, and it remained incorrectly positioned. The Top Cross In the fourth step we want to form a yellow cross on the top of the cube. Flip edges (if necessary) Our goal in this step When we have finished the second layers, the yellow edges can be in three different states (do not look at. It takes out the edge piece that's already there, and put it in the top layer. We solve the yellow edges on the top of the Rubik's Cube in two steps: First we orient them to form a yellow cross on the top (4.), then we swap the pieces to match them with the side colors (5.). Where y and z indicate rotations of the entire cube (and thus do not count as moves).What The Algorithm Does: It inserts an edge piece into the wanted position (while keeping the first layer done). U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2 This is one possible sequence of moves to generate the Superflip (starting from a solved Rubik's cube), recorded in Singmaster notation It consists of the minimal 20 moves under HTM, though it requires 28 quarter-turns: Instead, when Superflip is composed with the "four-dot" or "four-spot" position, in which four faces have their centers exchanged with the centers on the opposite face, the resulting position may be unique in requiring 26 moves under QTM. Under the more restrictive quarter-turn metric (QTM), the Superflip requires 24 moves, and is not maximally distant from the solved state. It has been shown that the shortest path between a solved cube and the Superflip position requires 20 moves under the usual half-turn metric (HTM), and that no position requires more moves (although, contrary to popular belief, there are many other positions that also require 20 moves). The superflip or 12-flip is a Rubik's Cube configuration in which all 20 of the movable subcubes (or "cubies") are in the correct permutation, and the eight corners are correctly oriented, but all twelve of the edges are oriented incorrectly ("flipped").
