Some promotional or novelty cubes contain patterns on the
stickers. Using the method above you can solve all of the cube as normal, except
you may end up with the center pieces incorrectly oriented. If this is the case
you can use one or more of these three processes to correctly orient them.
- Rotate the U center 180 degrees: U R L U2 R' L'
U R L U2 R' L'
- Rotate the U center clockwise 90 degrees and the F center
anti-clockwise 90 degrees: F B' L R' U D' F' U' D L' R F' B U
- Rotate the U center clockwise 90 degrees and the D center
anti-clockwise 90 degrees: R L' F2 B2 R L' U R L' F2
B2 R L' D'
The codes used can be read off his web site at: http://www.jeays.net/rubiks.htm
Or below, but his web site has much more and info on other
things like juggling, very cool. Unfortunately his email has changed so I
could not get hold of him.
Before we get started, we must work out a method for
describing the various moves that will be made. There are six faces, with the
following notations:
- Upper, or top face = U
- Down, or bottom face = D
- Left face = L
- Right face = R
- Front face = F
- Back face = B
We can turn each face either clockwise or counter-clockwise,
with respect to the center (i.e. a move that may be clockwise to you, when
looking at the cube, may not be clockwise for that face, in relation to the
middle of the cube). The names for the different kind of moves (I'll use the U
face as an example) are:
- A 90-degree turn clockwise on a face, is denoted by U.
- A 90-degree turn counter-clockwise on a face is denoted by
U' ("U prime") (Also note this is the same as U, done three
times).
- A 180-degree turn either clockwise or counter-clockwise on
a face, is denoted by U2 ("U squared") and is the same
as two clockwise turns, or two counter-clockwise turns.
