I have a rubik cube, which always have two swapped edges in the last layer. Solving it, however, is not very different to any highorder rubiks cube with the reduction method. Each side is made up of 16 centers, 16 edges, and 4 corners.

We have taken the algorithms from many different sites online and spoke to many of the fastest 5x5 cubers in the u. In the previous step we created a yellow cross on the top of the rubiks cube but probably the yellow edges are not all fitting to the colors of the side center pieces. Just a tutorial on how to solve edge parities on a 7x7x7. I just got a vcube 7 for christmas, been an avid 2x2x2, 3x3x3 and 4x4x4 player and i wanted to try my hand at the 7x7x7. A good systematic approach to the last two centers is to create a 2x3 block on one of the centers, then finish off the last 1x3 block the first 18 cases below will cover this. The six sides of the cube are coloured, so every corner piece shows three colours, every edge piece shows 2 colours, and every face centre only one. No matter which color i start with, there are always two edges in the last layer which remained swapped with each other. In order for you to be able to finish the cube, you will need to be able to solve a 3x3 cube, but being able to solve a 4x4 cube would also enhance your abilities for it, since the algorithms can be used. Each center is alone, each edge is paired with 1 other edge, and each corner is paired with 2 other corners. I usually do my last two edges intuitively, using the edge flipping algorithm a lot.

First, rotate the top 2 layers of the cube in a counterclockwise direction. Lion algorithm ll u2 ll u2 f2 ll f2 rr u2 rr u2 ll 2. Bring an edge piece into the working area move 1 bring an edge piece into the working area move 2 solve the first 2 of 4 unsolved working edges. The algorithms depicted in this section doesnt cover every scenario. You should then apply the edge mover formula with the lefternmost 2 layers as one. Solve 1 of 3 unsolved working edges move 1 solve 1 of 3 unsolved working edges move 2 solve the last two working edges move 1 solve the last two working edges move 2. This cube is exactly like solving the regular 3x3x3, but with an additional algorithm possibly needed because of the lack of centers. Notice that these first two algs are basically the same, just different setup moves the third algs is for when you get a case where the last groups two outside wings need. Next is the alg needed to pair up the final 2 groups of outside edges with their inner edge groups. Once youve assembled most of the edges together, use a sliceflipslice technique to complete the last few edges without messing up the center colors. This tutorial video will show you how to solve the last two centers on the vcube 7, the rubiks cube style puzzle.

The first is for even cubes with two inside edges needing to be swapped. I highly recommend learning them because not only can they be used on 5x5 they can be used on bigger cubes and cuboids making them very useful to learn. Simply take your time and learn the following 12 algorithms for the 5x5 l2e. One of the hardest parts for a beginner when solving the 5x5 is fixing the last 2 edges l2e before we get to the 3x3 stage. Reducing the last 5 edges is a matter of matching up, holding the lower layer steady and moving the top layer. How to solve a 5x5 rubiks professor cube i got a 5x5 cube recently, and learned how to do it by only learning a few algorithms. This is a case you more than likely already know but i felt it only made sense to include it anyways.

What i like to do is in your case match the greenyellow edge piece with the rest of the greenyellow chunk but backwards so you have parity on one half as you match it up just like you would with any edge, and it doesnt matter if you mess up a done edge because you will fix it later.

I do not recommend memorizing any algorithms for this, but rather develop a good visual on how the pieces are being manipulated to solve each case.
