7x7 Help !

Im stuck on solving the last 2 sides when your forming the 5's on each side. One side has 4 pieces right with one on the bottom that needs to go on the other side, And the other side has 4 pieces that are flipped each one (Ex. Orange-White, White-Orange, Orange-White, White-Orange) And the bottom piece just needs to switch sides as well :confused:

I don't think someone with a sup 3 minute 3x3x3 average should attempt to solve a 7x7x7.

Why not?

I'm not 100% sure what you mean, but I reccomend this video

That was months ago , I just haven't been on here since then. I've successfully been able to solve a 2x2, 3x3, 4x4, 5x5, megaminx, and pyraminx with ease so I feel i can do a 7x7 with a little bit of work.

 

[MostEd]

actually, use comutators

i make a line of 5 in the M slice, then i make as much or each on its side, then lastly, i use commutators on the go to solve the last pieces...

its not that you need to find them, or memorise them, just to know how it works, i could make a video for it

oh, its dedges,

....
well then you can use parity algs if its fliped wings on 1 dedge

 

[hydrotonics]

I'll try to explain this better. o=orange, w=white, g=green, y=yellow. So i have 2 sides that are left . oneside the colors go from top to bottom = y/g, y/g, y/g, y/g, w/o. And on the other they go w/o, o/w, w/o, o/w, y/g. Thats if im looking at it straight on and how the colors are.

make a picture using a camera

 

[uberCuber]

If I am understanding your explanation correctly: Have the edge that is mostly y/g in the FL position, with the w/o piece on top, and the edge that is mostly w/o the FR position, with the y/g piece on the bottom. Do 2u' R F' U R' F 2u (where 2u is a 2-layer turn), and then the y/g edge will be solved. Then all you have to do is apply your 5x5 parity alg to the w/o edge.

 

[yockee]

A good you tube channel to check out for things like this is Yu Nakajima's old tutorial channel CUTEXcuber. He shows you how to do everything.

 

[hydrotonics]

Ubercuber, is 2u' just the top 2 layers counter clockwise once or do i do a full 180 turn ?

 

[uberCuber]

Yes, 2u' is a 90-degree counter-clockwise turn of the top 2 layers. (If it was a 180-degree turn, it would say 2u2.)

 

[hydrotonics]

Thanks ! Now all i have to do is flip one piece over and i can finish it !

7x7 help

Does anybody know a good video showing how to swap 2 Center pieces on a 7x7? or can you give me a alg?

Also need help with last 2 edge pairing..

 

[Pandadudex96]

can't help for the center piece cause there's a bunch but for the last 2 edges, you could check out some 5x5 vids where you move a layer and swap the edge with R U R' F R' F' R and move it back to pair some up.

hope I helped.

Thanks, but i know how to solve 5x5 easy, just not 7x7 :S

It's basically the same concept but 7x7 is more fun because there's more work to do

Yea but the last 2 centers on 7x7 is not the same, maybe the edge pairing, but I don't wanna scramble it again until i figure out how to do the last 2 centers, cause i hate having unsolved cubes

MeMyselfandPi has a video explaining it.

 

[knuckles4204204]

MeMyselfandPi has a video explaining it.

I tried his, but he doesn't go into depth about it, just shows you, if he showed the algs it would be easier, I was just never able to understand MMAP's methods because the way he explains it is confusing. Monkeydude1313 is good at explaining his tuts good, as well as pestvic and redkb

 

[thackernerd]

esquimalt1 also has a centers video that's very helpful.
