8x8 edge parity

Rubik's cube solving This page explains how to solve a 6x6x6 cube. Every cube of higher order than 3x3x3 involves reducing the cube to a 3x3x3 cube, and then solving for that. The even cubes are initially easy to solve, but you'll potentially encounter parity problems you'll have to fix.

For the 6x6x6 there are 6 possible parity problem states. Fortunately, you only need to remember 3 series of moves, where 2 of them resemble each other closely.

Each side is made up of 16 centers, 16 edges, and 4 corners. With 6 sides this makes for 96 centers, 96 edges, and 24 corners, for a grand total of faces. Each center is alone, each edge is paired with 1 other edge, and each corner is paired with 2 other corners. The pictures show you how to go about solving the cube. The solution assumes you have at least some basic knowledge of how to handle the cube, so not all of the basic steps are shown. Make sure you always have the exact correct orientation or the supplied moves will not work properly.

Remember to first check the general instructions page if you're new to my solutions.

Steps to solve the 6x6x6 cube Do the top center and the bottom center. Only do the following parity fix if your cube has exactly 2 unsolved wings left Then swap 3 outer wings. Only do the following parity fix if your cube looks like this Then solve the cube as a 3x3x3.Want to ask a question? Please check our wiki to see if your question already has an answer.

The original puzzle has been expanded outwards to create bigger and more challenging alternatives: the 4x45x56x6 and 7x7. These puzzles may appear fairly complex and increasingly difficult as the number of layers increases, however their solutions remain relatively similar. Once you know the reduction method for the 4x4 and 5x5, you are technically able to solve any NxN puzzle given enough time. If you can solve the 4x4x4 and the 5x5x5 cubes then you can complete any size, even the 22x22x22 cube or the record-breaking 33x33x33!

For each step a walkthrough will be provided for the 4x4 and 5x5 cubes, as most even-layered and odd layered puzzles share the same properties 4x4 and 6x6, 5x5 and 7x7 etc. The first step involves building two opposite centres; these are normally white and yellow as these are the top and bottom faces for most people who know how to solve a 3x3. Try finding one if not, simply build it by doing at most 2 movesand then find another to insert next to it.

Next, you can put your now solved centres on the left and right of the puzzle and solve two more adjacent centres. Even though odd layered cubes have many centres, there is always one that is directly in the middle of them all. For 4x4 and above, this is not the case. This means that when building your centres on even layered cubes, you must build the centres according to the colour scheme i. You should be able to apply your knowledge from the first two centres to build two adjacent centres without disturbing your original two.

You should now be left with two unsolved adjacent centres. Every other centre should be solved.

Gigaminx (5x5x5)

There are only a few different combinations for the last two centres. Two of which are shown here. According to the notation of big cubesthe Rw refers to the wide rotation of the two right layers.

To build your first centre, construct a bar by attaching two of the inner centres to the defined centre piece. Next, construct another bar of the same colour, but make sure that this one has two corner centres and one inner centre.

Finally, build a third bar with the remaining 3 centres and insert it next to the first two. The second centre will be opposite the first, so the only difference in solving is that you have to undo certain moves to preserve the first centre.

In the same way to the 4x4, you can solve two adjacent edges fairly intuitively whilst preserving your white and yellow centres that are on the left and right. The only difference here is that the defined centre piece shows which colour you must build. Just build the centre bar for one colour and a second bar and insert them. The result of this combination of moves is shown in Figure 2 below.

Simply repeat this process until you have four solved edges in the top layer see Figure 4. As long as you only perform slice moves when the centres are as shown in the two images i. Always make sure to keep the centres horizontal. Everything is exactly the same as the previous 4, just construct each edge and push it into the top layer.

After this you should now have 8 total solved edges on the top and bottom. For the last four edges on 4x4, all you have to look for is pairs of adjacent edges.

In Figure 6, the two white pieces can match up to make an edge. This algorithm flips an edge in the middle layer. This algorithm is extremely useful for edge pairing in big cubes. But for our purposes, we just need an algorithm that will efficiently solve simple edge pairs. Take Figure 6 as our example, the following moves would solve the green-white edge, but try and visualise how it happens:.

This means that the location of the piece is above the piece on the same edge. The Uw simply fixes the centres and pairs up the edge pieces. This is one of the simplest stages due to the low number of combinations, hence the necessity for only one algorithm this algorithm can also be utilized throughout the first 8 edges stage to correctly position an edge piece.Forums New posts Search forums.

I have a question and my own suggestion to cubers, who likes big cubes. How are you solving Parities of last two Edges on big cudes, like 6x6, 7x7 etc? Clearly, that: - using formulas of 5x5x5; - thats formulas can be corrected by moving not only two sides together like Rwbut three also; - too many cases, when you have to use several formulas one by one; - so too much time spends for these operations.

So, I have my invention for these situations. During, I looking for such edge - solution of the one will be easy to do, using one formula alone Or make such edge by myself.

And put this "unsolve" edge to the up side, remember it as like not completly solved. And now come in handy my "unsolved" edge - I get it into working space. I conclude three edges, with not breaking a main part of "unsolved" edge in current example: it is black-blue block of the one. Eventually I get harvested parity of last two edges, for using known simple formula!

That is my idea. Last edited: Oct 11, Novriil Member. Muesli Premium Member. I use the Parity algorithm but only moving the slices that are flipped.

It's probably stupidly inefficient. Novriil said:.New customer? Create your account. Lost password? Recover password. Remembered your password? Back to login. Already have an account? Login here. Parity is a speedsolvers nightmare, but what actually is it and why does it occur? Parity only occurs on 4x4 cubes and up. You cannot get parity on a 2x2 or 3x3 cube due to the nature of the puzzle itself. A 4x4 however, is different, as you have floating centers apposed to fixed centers.

Parity can occur if you put the wrong center piece in the wrong slot. It's hard to describle but on every face on a 4x4 you have 4 center pieces that each have a specific slot they must go in. If you put a center piece in. This is when 2 pieces of the last layer are orientated incorrectly. These are when the last layer is orientated correctly but they are in the incorrect position to solve using the regular 3x3 method.

Need help solving my Shenshou 8x8x8. Thread starter sainclair Start date Aug 20, Tags 8x8 help needed shenshou. Joined Aug 20, Messages 4. Hello, I recently got an 8x8x8 Shenshou cube and I've managed to solve all the centers but the last two, and I'm having a hard time understanding how to solve these last two centers.

Unless someone has solved an 8x8x8 and can tell me that it's markedly different from solving the 7x7x7's edges I don't think I'll need it. I've searched far and wide and cannot find a guide to solve an 8x8x8, in fact most places don't even have discussions for it. So can anyone give me some pointers on how to solve the last two centers on an 8x8x8, and maybe the edges too? Form lines.
