7x7x7

The 7x7x7 V-Cube is the next step up from the 6x6x6 V-Cube. The basic idea is to reduce the cube so it's essentially the same as a 3x3x3 cube. Once that's done, it behaves like a 3x3x3 cube. To buy this cube, click here.

The Basic Plot
  1. Reduce centers
  2. Reduce edges
  3. Position edge quintets
  4. Solve corners
Step 1: Reduce Centers

This is similar to the Professor Cube, in that there is a fixed center piece. Although you can solve any colour in any order, I'll begin by solving the white center. I assume that you can solve a 5x5x5. In this video, I'll show how to reduce the 1st face of centers.


Solving the remaining centers is similar to the 5x5x5. When we get to the last two centers, things become a little more interesting. We use the corner piece series on different slices to place all the individual pieces.



Step 2: Redue Edges

All centers are now in place and it's time to match edge pieces to create edge quintets. You'll notice that instead of there being 1 edge piece joining two faces, there are 5. The goal is to first match 11 of the edge quintets. Once that's done, the last edge quintet will either be correctly matched automatically, or else will need further dealings. Use the edge piece series as follows
  1. Find five edge pieces needing to be matched
  2. Bring them together (centers will be disturbed)
  3. Use an edge piece series to move the matched edge quintets onto a different face. Make sure that the replacement piece is not already a matched quintet.
  4. Return the centers
This video will show a variety of techniques which will get you to the final center.


Help! I Only Have One Edge Quintet Left To Make.

Alright. There are three separate situations you'll encounter where you have one edge quintet left to make. Each of these situations has a different pattern of individual edges pieces, and each has its own method of solution.

CASE 1: Pattern YNYNY

In this case,
  1. Turn the second slice one turn
  2. Re-solve the centers
  3. Re-reduce the edge quintets

CASE 2: Pattern NNYNN

In this case,
  1. Turn the bottom three slices one turn
  2. Re-solve the centers
  3. Re-reduce the edge quintets


CASE 3: Pattern NYYYN

In this case,
  1. Turn the bottom two slices one turn
  2. Re-solve the centers
  3. Re-reduce the broken edge quintets


Step 3: Solve Reduced Cube

Now treat each edge quintet as a single edge piece. Turn only the outer layers. Position the edges exactly as you would for the 3x3x3 Rubik's cube. Then solve corners as well using the corner piece series.




And that's it. Your 7x7x7 V-Cube is now solved. I trust this site has been helpful. If you have any questions or want some clarifications, please use the comments to do so.  To buy this cube, click here.

  2. No offense but you need to be more clear on the moves you are doing, using notation is very good and its not at all hard for your viewers to learn!

    1. @Ben,

      No offence taken! The reason I haven't used notation is simply because Marshall doesn't use any notation on his original site, and this site is supposed to be simply an extension of his site. I could quite easily put notation (there are 1 or 2 places on the site where this is notation) but for the most part I'm going to leave things as they are.

      If there's something specific which you're not understanding, let me know.

      Delete
    2. can you write the notation for NYYYN, NNYNN AND YNYNYN

      Delete
    3. Gamer Guy, it's not notation for an algoruthm, it's just my attempt to show which pieces in the edge quintets are correctly oriented. Eg. on NYYYN, I'm saying that three pieces in the middle of the edge quintet are facing the same way, while the two outer pieces are opposite.

    1. Can you tell me exactly what isn't clear? Are you having trouble seeing where you need to place the pieces? What moves to do? If you can be clear, here, I can make a new video. It will probably be a couple of days, though.

    1. @Anonymous,
      You are showing yourself to be - how shall I put it - somewhat of a tool.

      You don't have the decency to leave your name (wonder why?), you apparently can't compose complete sentences, and your rude attitude is about what I'd expect from a leech.

      You clearly haven't worked your way through the Ultimate Solution method. If you had, you'd realise the method is about not having to learn algorithms. It's about solving and understanding the puzzles. I've put many many hours into this site, and into making the original ultimate solution method understandable. The least you could do is act civilised.

      This reply is probably way over your head...

  7. Thank you for putting so much effort into this site :)

    I just got my v cube

    Looked for a few tutorials on YouTube but I could not understand them that well then I came across this site and after looking at all the videos on the v cube 7 I solved it :) everything you said was very clear and the way you showed everything was flawless :)

    And again thank you so much for showing clueless people like me to solve this monster of a cube :)

  8. Thank you very much for this site!
    I did not watch every single move, because i was interested in the last 2 edges and the parity move. Now i understand the last 2 edges, the parity -to be honest- i dont't understand. But now i'm able to solve even parity without having learned the complicated algorithm...

    and special thanks for your proper videos, one really understands what you mean, you don't move on too fast and you move slow enough, that one can see what you're doing.

    perfect! Thank you very much!

  9. Oh man, you legend!

    Coming up from the 5x5x5, the algorithms are highly identical but for the beginning: the last two centers... I've been struggeling by myself for weeks; I couldn't find a consistent algorithm myself.

    So I started looking online for a good sequence and you sir, are the King of Cube Solving Tutors.

    Where most give you the notation sequence and leave you to struggle, you took the time to make a really good video to help others out. The video is very clear, not too fast, not too slow... going into the underlying mechanisms and through it all, telling me not to worry. :)

    "V-Cube 7x7x7 Pt 6 - Centers" really helped me with solving my 7x7x7, thanks a bunch!

  11. Hello Chareaves, could you please help me out. In your video "V-Cube 7x7x7 Pt 10 - Making Edges - Three Left To Make" at 0:58 I am unable to make "this" as my phase 3, because I have an orange-green on all three rows. Am I completely missing a step? or did you just get lucky and not have this problem while filming? Please help me out, it would be much appreciated.

    1. Hi K-Ned,

      Glad to help. I would have just filmed whatever arose, but all situations can be dealt with. So I'm assuming you have three edge quintets left to make. Is it possible to post me a pic showing all 3 unmade edge quintets, or else a video, or else fully describe them for me? If you can, I'll make a new video showing how to deal with it.

      Delete
    2. Thank you for such a quick reply, and being willing to help. I was actually trying to problem solve my own problem and actually came across a solution. I can still describe it for you, so you can make a video for anyone else who comes across this problem, if you would like of coarse. Unfortunately I recently moved out, so I do not have any camera of any sort, so I will do my best to describe the problem. I have 9 edges all matched up and paired ready for the next step. (mine was with black-green, but I will stick with orange-green for convenience of video reference) I am trying set up one of my edges for a phase 3. this is the side without any orange-green that will swap places with the full edge of orange-green once I turn them into place. You point to it in the video I referenced last post at 0:58. That side does not have any orange-green, so you are able to use it as your phase 3. I had orange-green on all of my 3 available sides. So unless I could use the one already matched up edges as my phase 3, then I did not know this. As I was problem solving, I realized I had to do this step twice. Once to get 4 orange-greens on one of the same edges, this way I was left with a "blank" edge I could use for a phase 3. I don't know if this is the best way to solve it, but it worked for me. I hope I described it well enough for you.

    3. No problems. To quote George Constanza "that's what I do". (If you've seen the episode - The Seven - you'll get why that's funny).

      I think what you've done is what I'd do. It's the same kind of thing as making edges in a 7x7x5. Basically, we're looking for a way to bring pieces together, even if it's only one at a time. In my video, I happened to have a few together already, but if I didn't, I'd just try and get two together, using the same technique, and then get three together, then four, and then 5. Generally this will work for the edge-making process.

  12. Are there algorithms for how to solve the last 2 edge quintets?

    Do you recommend a particular source for them?

    I just watched the appropriate video above and am unable to follow the moves. I've solved the 4x4x4 and 5x5x5. Perhaps I can use a similar algorithm.

    Thank you!!

  13. Hi. I am a huge fan of your site. I came across the Ultimate Solution when I was looking for a method of solving the cube that was more than just mindlessly memorizing algorithms. I had a hard time following Philipp Marshall's website, but your site was exactly what I needed. This method makes solving the cubes so much fun. Thanks for all your work.

    I was wondering if you could explain the logic of how to approach the three possible scenarios when there is only one edge quintet left to solve. Rather than just memorizing how many slices to turn in each scenario, I would like to understand how to determine the number of slices to turn prior to resolving the centers in each scenario. Thanks.

    2. Thanks so much for explaining that. It makes perfect sense, although I never would have figured that out on my own. I guess it just goes to show how much I have yet to learn about how the cubes work...

      I'll look forward to seeing your 11x11 review. I'm only up to the 7x7 so far, but I'm looking forward to working up to the 11x11. Thanks again.

    3. It's the exact same way I'd place edges on a 3x3x3. Are you aware of the method I use for that? If not, have a look here: https://www.youtube.com/watch?v=daDS4GlO8BE

  19. Okay. So I completely understand everything about the 7x7x7 except for the last two edges. And Once I get them I can solve it easily enough but they can stump me long enough I get crabby and have to put it down haha.
    I have been searching for someone else's way to solve it and I came across yours. It seems simple enough...I like how you think your way around the cube instead of using algorithms, there is just something not clicking for me when it comes to understanding your 'flipping' for the last two edges.
    Could you help somehow? And if you have answered this question before feel free to just direct me to that comment instead of re explaining it all. Thanks for your time :)

  20. Awesome work! I've been on many sites, and I like your style best. I'm working on my 7x7x7 and do fine until the last two quintets. When you say in a video "I like to think my moves out first" but don't say what you are thinking, it can be difficult to follow. My biggest problem, is in the last quintet. When I move a 2nd piece down, then chase the centers around as you do, I frequently wreck many other edges. I think I am doing what you show, but obviously not. Eventually, when I resolve those, sometimes my last quintet is right, but many other times it is not. It feels like rolling dice until I finally get a 6. Also, I can't figure out how to link my profile, so I'll just tag it here. --cdeerinck
