Hey all-
I have a solving question about the megaminx. I can solve one
unassisted pretty easily, but there's one setup that I can't fix.
Any help would be appreciated.

This happens when I have most of the minx already solved. When I am
orienting the last 5 edges, it sometimes ends up that two of the
edges are switched(e.g. the top face is blue, the left face is
yellow and the right one is dark orange. The yellow/orange edge is
oriented correctly. The blue/yellow edge is where the blue/orange
edge should be, and the blue/orange edge is where the blue/yellow
edge should be. Both are oriented correctly otherwise. All other
edges are correctly placed). I've tried everything that I can think
of but I can't get these two switched back around without remixing
the minx and restarting from an earlier stage.

It sounds like you have a 6 color megaminx! This is the parity
problem. Essentially what you have to do to fix it is "swap" on of
the last face edges with it's duplicate. Actually what you're doing
is rotating 2 LL edges and one on the oppositite face, which fixes

I supplied an 18 move algorithm to fix this very problem a while
ago. I'll refer you to message 1707 at
http://groups.yahoo.com/group/speedsolvingrubikscube/message/1707 .
I hope that helps.

I just was given a Megaminx for Christmas. After not messing it up
for some time for fear of never solving it I finally gave it a spin.
I was very excited to be able to solve almost the entire puzzle using
a layer-by-layer method. Then, because I solve corners first for the
3x3 I didn't know any last layer algs for the 3x3 to use on the
megaminx. I could however come up with an alg to place the corners
in the right spot, and another to twist them. So now all that are
left are the edges. So I was wondering if anyone has any algs that
moves the last layer edges and another that flips them, without
messing with the corners. If not I was wondering if anyone had some
algs that did the edges and then some that do the corners.

Message 5 of 15 , Jan 6, 2003

I personally would recommend doing edges (orient then permute) and
then corners (orient then permute), but there are algs to do what
you're looking for. For example, I found these at
http://web.idirect.com/~cubeman/megaminx.txt :

3 cycle of edges (uf, lf, rf)
R+ F+ U+ F- U- R- L- U- F- U+ F+ L+

2 edge flip
L-- R++ F+ U- R+ U+ L++ R++ U+
R-- L-- U- R- U+ F- R-- L++ U-

2 edge flip
R- F- U+ L- U- L+ F+ R+
L+ F+ U- R+ U+ R- F- L-

+ is one "click" clockwise
- is one counterclockwise
++ and -- are two clicks, in their respective directions.

I do the LL in order of OE, PE, OC, PC, so I don't actually use the
algs above. For the two edge flip algs above, I don't actually know
which edges it flips.
For OE, I use (with the LL on U):
F+ U+ R+ U- R- F- (flips adjacent edges UF and UR)
F+ R+ U+ R- U- F- (flips opposite edges UF and UB - with B
L+ F+ R+ U+ R- U+ F- U-- L- (flips all but UB, with B adjacent to L)

For PE, I use:
R+ U+ R- U+ R+ U-- R- (3 edge cycle counter clockwise)
R+ U++ R- U- R+ U- R- (3 edge cycle clockwise)
R+ U+ R- U+ R+ U- R- U+ R+ U++ R- (swaps two pairs)

I'm not even going to go into the corner algs I use... There are two
many, and I don't know of a good way to put them into notation. Some
cube algs can be applied for the OC and PC steps, as long as they
don't affect edges at all. Some day, I'll come up with some
notation, and put a section on my website... Hope this helps. Also,
if you look back for it, I did post some PC algs a while ago in this
group.

Here is a question for the Megaminx masters out there:

My Megaminx has 6 colors. Two of my edge pieces are missing
stickers; one orange, and one yellow. So if I always started solving
the same color (say yellow) and made sure that I always started on
the same yellow . . .could I avoid the parity problem, because I have
two of the edges marked?

Thanks,

I'm sure this depends on how much your puzzle has been used (and
therefore how loose it is), but I can perform triggers on my megaminx
after having lubed it. It's definately not as quick as a cube,
though. My megaminx is a couple years old now, and "well-loved" -
it's the old 12-color, tiled Mefferts version.

Thanks- I've had it since christmas and it's pretty used, but not
really loose. It moved really quick after lubing- almost faster than
the cube I have that I just lubed on the same day. :)

What was the color scheme on the 12 color tiled megaminx? I just
ordered a megaminx and a set of tiles, and am wondering if there is
an official color scheme.

I don't know about it being an official color scheme, but it's like
this:
Northern hemisphere = dark colors
- dark green (U face)
clockwise around U face:
- dark blue
- red
- brown
- dark pink
- purple

Southern hemisphere = light colors
- light green (D face - opposite dark green)
clockwise around D face
- light blue (opposite dark blue)
- white
- yellow
- orange
- light pink
