What's wrong with my cube??????

[martian]

When I solve the cube to the last bit, it just happens like this.................

What's wrong?????

Hi martian, its easy, have a look at this:
If your cube still does not solve then another position it can be in is to have the whole cube solved except for one edge is flipped like this,

Now hold your cube as in the diagram and do the move
r ² B ² U ² l U ² r ' U ² r U ² F ² r F ² l ' B ² r ²

What are the notation for 4x4


Are mine correct?

R= Right
R* = right and right Inner right
r = inner slice only

~~~~

Also when you get that and dont have a 3x3 PLL algorithm/OLL

It is called a Parity. Which only the 4x4 can have. (unless Blindsolving)

 

[DANrulz81]

Yes, r is only the inner slice, you can watch the whole Notation here:

Thanks a lot!!!!!!!!

By the way, can I find this algorithm on the Internet?

I think http://bigcubes.com is easy enough to remember.

He has everything you need

Or you could go to my video: www.youtube.com/desicuber

Look under my videos, and you'll find Rubik's Revenge Edge Parity 2,

I highly suggest NOT learning from Dan Brown's tutorial unless you wish to learn way more than you need to.

 

[Blueside]

Well it's good enough.

There's nothing wrong with learning more than you need to. In fact, I think Dan Brown's videos are a great start. He is well-spoken, and he goes through each step slowly enough for a beginner to follow along and understand.

I learned the parity from cubestation.com

r2 B2 r' U2 r' U2 x' U2 r' U2 r U2 r' U2 R2 U2

r is the slice and outer layer

I know! I can solve a 4x4x4!

if you have any future parity alogorithms you can type 4x4 parity algorithms you can type it into google and steven pochmans (sorry for any misspelling of the name =] ) website should come up
