How to dismantle my cube?
Twist the upper layer of half a quarter of tour (or of an eighth of tour if you prefer).
Now the 4 edge cubes (cubbies with 2 colors) are exactly above the edge cubes of the second layer. All you need
to do is to slide a flat screwdriver or a knife between the first layer edge cube and the one of the second
layer and to lever it up : the edge cube of the upper layer jumps and its easy to dismantle the rest of the cube.|
BE CAREFUL: this is valid only for the real Rubik's Cube, the one which have the Rubik's Cube logo (and I'm not sure its
valid for the Rubik's Cube of the 80's). For the others, the mechanism isn't the same and you mustn't lever it up! There's a
screw in the central cubes which can only be accessed by removing the stickers.
My cube's stickers are already gone!
That's not surprising! The original stickers on a Rubik's cube don't last long. There are composed of 2 elements :
a very thin plastic protecting film which goes off rapidly, and a colored paper directly stuck on the cube,
but its colors goes off quickly when the protecting film is gone. Here some solutions :
- Ways to make the stickers last longer :
- Here is an interesting method that Brian Johnston e-mailed me :
he uses clear flat (non-shiny) nail polish around the edges of all the stickers to keep them in place. It works like a charm
and best of all prevents others from peeling and replacing the stickers.
- some people use some transparent adhesive paper (available in hypermarket) more thick and more resistant than adhesive tape. You mustn't wait stickers to
be totally destroyed : when the protecting film of the stickers starts to go off, all you need to do is to
put this transparent adhesive paper : cut it smaller than the stickers so that it doesn't go off when you
play with the cube (even if the edge of the stickers gets a little damaged).
- Replacing some old stickers :
- some other people use some colored adhesive tape. You can find some various colors almost matching with the
cube colors. Rather choose a smooth tape in order to avoid degradation.
- personally, I rebuild new facelets : I cut some colored square which approach the original colors in magazines or something
else. Then I coat with plastic with some adhesive tape that I curve behind the colored squares. Then I stick the squares on the Rubik's Cube facelets
with neoprene glue (since it is a plastic-plastic contact since the adhesive tape is curved behind the squares.
The result is a cube that last one year ore more. But you must count half a dozen of hours to do a perfect
work which will last long... (choosing and finding the colors isn't the fastest thing).
Advantage: the facelets last a long time.
Inconveniences: very long to do; hard to clean the cube when you must renew it (neoprene glue persistent).
Where can I buy a Rubik's cube?
You can find it in hypermarkets and toy stores about 10$ and you can buy one on the internet
(look at the online stores in the page of links) (column "Miscellaneous")
I have a Rubik's Cube with pictures on it, how do I orient the center pieces?
If you are already familiar with a normal Rubik's Cube (without pictures), you should be able to solve it
without problem, at least for the first two layers if you take care to the orientation of the center pieces
while you solve the cube. Indeed, for the first layer, all you have to do is to put the back edge cube
behind the center piece, the front edge cube ahead, ...
For the second layer it is completely possible
to do the same thing. For the last layer, it can be harder depending on your solving method for the last layer.
With the method I present on my site for solving a normal cube, there's no problem since the main algorithms
preserve the central pieces orientation.
However if don't manage to do it, here are some algorithms that may help you:
To understand how it works : all you have to do is to review the movements for each face:
- U R L U2 R' L' U R L U2 R' L' : rotate the upper face center 180 degrees
- F B' L R' U D' F' U' D L' R F' B U : rotate the upper face center clockwise 90 degrees and the front face
center anti-clockwise 90 degrees
- R L' F2 B2 R L' U R L' F2 B2 R L' D' : rotate the upper face center clockwise 90 degrees and the down face
center anti-clockwise 90 degrees
example for the first algorithm (U R L U2 R' L' U R L U2 R' L'):
U: U,UČ,U,UČ : U6 = U4 + UČ, so the U face center will turn 360 degrees
and then rotate 180 degrees
R: R,R',R,R' : R0, so the R face center will not move
L: L,L',L,L' : L0, so the L face center will not move
