Easy guide picture 5x5 cube

Postby wmchooi » Mon Jan 17, 2011 7:28 am

I have modified my own solution for a picture cube 5x5. :lol:

I cant find a proper website specific for this. I am using the original RUBIK'S cube iphone game. Finally found a method myself for arranging center pieces.

So I want to share it here... it is the official website for your game & you dont have solution for it here.

My method use least memorization... and now horrendously long formula... lot of pictures & how to swipe on ur iphone


Any comment pls. http://www.picture5x5rubik.blogspot.com/

btw, I don't know why my post wont appear? when I click view my post nothing appears

Hi guys, there any expert out there on 5x5?

[/b]Can you share any good solution to re-arrange order of center pieces? I tried google but not much info.

ELLABORATION:- For standard 5x5 its easy, but with picture you need to solve in certain order to make it like a picture. IF you dun get what I mean. Look at cube below... pic of the lady (Nami) is all out of orientation & order?

I only have 1 method which I figured myself... very long & tedious.. especially if I end up with this. 2 piece of the lady (Nami) in the "middle lot" center piece is out of order.

I used 3 exchange method.. kinda of dumb :roll: actually but works for me so far. Matter of time... that is..
http://picture5x5rubik.blogspot.com/p/step-3.html

PROBLEM STATEMENT:- cant solve if I am left with 2 "corner lot" center piece out of order. I can only solve if 2 "middle lot" center piece out of order. For 2 "corner lot" center piece, I re-arrange in a "zip & switch" (sorry for the vague explanation but detailed here http://picture5x5rubik.blogspot.com/p/step-2.html ) It takes time, try & error, and not systematic.... until I get it into a 2 "middle lot" center piece out of order. Like pic above Is there a parity here?

This is my first topic. Excuse me if I am not posting this right.


P.S. to borginator2;- Thanks for kindly explaining about the post moderation process.

I am not a 5x5 expert, but I found this video - http://www.youtube.com/watch?v=ImyYA-IOAes&NR=1&feature=fvwp. This is part two. In the first part, he solved the center edge pieces; in this part, he solves corners in the centers. At 4:18, he uses r U' l' U r' U' l, which was explained earlier in the video, to cycle three corners in the centers. So, maybe you have three inner corners not solved instead of two. Of course, the video could be wrong.

Hi there Zeator,

Thank so much. It is real effort finding the video. Really hard I know.. been trying as well.

I have used that algorithm. It's a bit like modification of the standard Corner Piece movement form lar petrus I think. It works only for "corner lot" center pieces... which is y he solves "middle lot" center piece.

left with 3 pcs in order is not a problem for me in particular.

PROBLEM:- Parity issue.. you are left with 2 pcs out of order in the "corner lot". I found my way to solve Parity, took me days for this idea... left with 2 pcs in "middle lot" like step 4 here http://picture5x5rubik.blogspot.com/p/step-4.html

Actually, my current triple exchanges method can solve both "middle lot" & "corner lot" center piece. Doesn't matter which way u attempt first.... as long you are left with 3 pcs in order, you can solve. BUT If you got PARITY... I can only solve Parity on "middle lot" center pcs.. that's why I solve corner first!

IF it is on "Corner Lot" center pieces.. like this picture here below. KO.. dead.. try & error... sometime I scramble 3 pictures to get out of this. I got no systematic approach.

ANYONE? CUBE EXPERTS? or not.. doesn't matter.

Oh ya..

Any ideas from you Zeator? would be great for me to try. I exhausted the different move I adapted from other 5x5 websites I know.

Key Problem with lots of the common moves for 5x5 is that it screws up orders of other plane pictures. There are made in way... not meant for picture 5x5 cube which order is as important to maintain on all sides completed.. not matter of j placing the colour center pieces in the center. That's a challenge!

I am not much into speed really... more of wanting to solve every possible & hardest combination of cubes... those parity are of interest. Parity on edge pieces on 4x4 & 5x5 is interesting, but with 5x5 picture.. there are parity on center pieces! May b I am wrong??

Do not know where else to find cube experts advise.

If you only care about what happens to the inner 3x3, you can use r U2 r U2 r U2 r U2 r to switch two inner edge pieces in the U layer. The only other pieces affected are some in the outer layers.

r' U r' d2 r U' r' d2 r2 cycles three inner corners in the B layer. r2 d2 r U r' d2 r U' r does as well.

I found these algorithms here - http://michael-gottlieb.blogspot.com/2008/05/solving-4x4x4-and-5x5x5-supercubes.html.

Thanks again Zeator.

... but unfortunately the algorithm r U2 r U2 r U2 r U2 r did not work for two edge pieces as I hoped for.

That website wasn't clear in his explanation, his choice of words rather confusing. Lot of other useful tips tough, but not specific about all the different parity solutions.

r U2 r U2 r U2 r U2 r It actually exchanges 2 rows of edges, not two edge pieces... I took snapshot of it step by step & purposely created a page for you so that you could verify I did this correctly.
http://picture5x5rubik.blogspot.com/p/discussion.html

Summary:- r U2 r U2 r U2 r U2 r is to switch 2 rows of edges pieces, not only two edge pieces.

p/s;- I am able to cycling between 3 pieces. Lot of ways as you pointed out. But 2 is the problem. I can solve 2 piece parity on "t" cross like this

Still stuck with systematic solutions for two on center piece on corners.. like this..

You are right. When I did that algorithm before, I looked at its effect incorrectly.

As for your issue with the two inner corners, in the last image on this page, http://picture5x5rubik.blogspot.com/p/discussion.html, if you look closely at the face with Tony Tony Chopper on it and compare it to the one on this page, http://picture5x5rubik.blogspot.com/, you can see that the center piece needs to be rotated 90 degrees counterclockwise.

So, I think what you need to do is put the Tony Tony Chopper face on the left and the Luffy face on top, rotating the U (Luffy) layer so that the two unsolved corners are in the front. Then, do what is on this page, http://twistypuzzles.com/forum/viewtopic.php?f=8&t=20118, followed by what is in the video description of this video - http://il.youtube.com/watch?v=DqxwW-C4tts. This gives you the following algorithm (which should solve the cube you linked to earlier):

r2 U r' U r' U' r U r U2 r U2 r U r2 U r U' r' U' r2 U r M E M' U' M E' M.

you are right!

My chopper center piece was wrong. When I re-arranged I could solve. Means I did not have that problem parity that I was looking for.

I gonna re-play this 5x5 a couple of times again to see if such parity exist...

what do you think? Does parity of 2 pieces left only happens to the "t" crosses of the center pieces? or they could happen on "corner lot" piece.

Based on what I've seen elsewhere on the Internet, I don't think it's possible to have just two inner corners switched. The closest you could get would be to have them switched and have the center on that face rotated too. r2 U r' U r' U' r U r U2 r U2 r U r2 U r U' r' U' r2 U r can do this.
