This thread will teach you how to solve a 7x7 cube. You must know how to solve a 3x3, and knowledge with previous big cubes such as the 4x4 and 5x5 will come in handy. This is the method i use and i average about 6.20 minutes with a PB single of 6.01. Have fun!

Step 1: Centers


Step 2: Edges


I hope i helped you to solve your 7x7 with decent speed. Check out this link for more info: http://www.aus-speedcubing.110mb.com/index.php?p=1_34_7x7-Speedcubing

Have fun!

Don't mean to be rude or annoying, but I think you mean 3x3.

Anyway, excellent tutorial! I'm sure a lot of people will find this handy. I had some trouble figuring out how to solve a 7x7 myself, when I first tried. (Kinda obvious, but I'm just saying for the sake of it. ;))

My nets too slow at the moment >.<

So I'll just ask...

Is this how you do Centers?
- Solve 3x3 centers
- Solve 1x3 inner-tredges
- Solve the rest like a 5x5

And edges?
- Slice around M or E to create the first 8 edges
- Freestyle the last 4 edges?

First 4 Centers
-Solve inner 3x3 block
-Expand with two 1x3 blocks opposite eachother
-Add two 1x5 bars to finish off the center.

Last 2 Centers (Like Dan Cohen's way)
-Make a middle 1x5 bar on either side
-Make another 1x5 bar next to the middle bar
-Make another 1x5 bar next to the bar which is next to the middle bar.
-Make sure their is only two 1x3 that arn't solved, if theirs three do a Rw Lw' U2 Rw' Lw
-Solve it like 5x5 centers.
-Do a commutator too change those two unsolved pieces in the 1x3's.

Edges
-Solve first eight freestyle by making big edges of 5 identical pieces and store 4 in U face and 4 in D face.
-Fix up centers
-Make 3 inner edges (Like a 5x5) of the 7x7 edges for the last 4 whole edges.
-Finish off the last 4 edges by solving them like reduced 5x5 edges.

funny, I've never posted on a cubing forum.. but I got my V7 a month or so ago and the technique I use is almost identical to the tutorial listed here... but i figured it out all on my own! w00t.

the only exception is that I just freestyle the last 2 faces. I'm getting better at it but the last two faces definitely take me the longest out of any other step.

Hey,

I just solved my 7x7, but I use a different edge pairing method: At first I pair up 2 pieces, then 3 pieces (like you would do on a 5x5) then I extend these 3x1 blocks to 4x1 and finally to 5x1. But there's one problem: if you get parity on the last step, it doesn't matter, you can use the 5x5 algorithms, but, if you get parity at lining up 3x1 bars, you can't use it (I tried to, changed the alg. so that i turned 3 sides on 7x7 instead of 2 sides on 5x5 etc.) - you will mix up the centers ....


Any suggestions?

I think the problem is, that when solving the 5x5 and using the algorithm ( (Ll)', U2,(Ll)',U2,F2,(Ll)',F2,(Rr),U2,(Rr)', U2,(Ll)2 ) you involve the other edges, but it doesn't matter, because they aren't assembled yet. But if you do the same (3x1 edges) for the 7x7, you involve some pieces of the already solved 5x5 center, so you mess up your cube.

Do you have any adwise for me??

when using triple layer turns for edge algs, you don't use double layer turns for turns that are usually single layer turns, you still use single layer turns. the only thing that changes is double layer turns (r becomes r3, U stays U)

I have almost solved my 7x7 centers. I am only missing the center parts of the outer 1x5 sections. He shows how to solve the last two pieces if they are the second from the edges of those 1x5 sections, but how do you get the centers? o_O

I was interested in the last two centers, but I cant see the difference between green and red in your video!
