Hello, people from Crazy Village,

I don't kow how I can solve my tet jupiter.

Pairing edges with circle edges was ok.
Pairing corners with circle corners was accidentaly.
The rest was random.
Randomly I get this situation:

Two paired edges are flipped. Only the white bottom face is unbandaged.
The easy sequence from Pyraminx to flip 2 edges doesn't work because the circles would destroyed.

Does someone know a sequence ?

Cheers,
Andrea

Hi Andrea,

have you checked Burgo's method?

This is how I do it:
Spoiler ahead, please highlight
[1. reduce edges and corners
2. place all edges and orientate them correctly
If a flip of two edges is required, I do this:
I hold the white 0 (unbandaged) face as U, one tip is pointing at me. The left face turn is L, the right face turn is R. The back face is B
R L' R' L y L' R L R' y' (y is a clockwise turn of the whole puzzle by 60 degrees)
Edges RL and BL are flipped, two pairs of corners are swapped
3. place all four corners. I use a [[1,1],1] commutator R' L R L' B L R' L' R B'
4. Orientate the corners
all four by a 16 move sequence
three or two as in Burgo's method, please, have a look at my diagram above.
My diagram is for a Mercury. Hold the white face as B instead of orange in the Mercury case.

Feel free to comment on that post too Andrea, I was hoping it would spark some discussion, I see it as a work in progress. Maybe a little discussion would enable me to edit it where it is confusing and make it easier to understand?
Cheers,
Burgo.

Hello Friends,

I can solve the Crazy Tet Jupiter. But if I get the situation posted Tue Oct 25, 2011 2:21 pm I must solve this with intuition.

I put the white fave into the back and use (R L' R' L') x 3. The orientation I solve similat to the skewb corner orientation.

For the Crazy Tet Mars I don't dare to scramble it. I have no idea to solve it. Burgo, I read your posting from Thu Oct 06, 2011 11:48 pm. Perhaps my english is to bad, that it helps me only a little.

Cheers,
Andrea

For the 2 edges flipped on the Jupiter Tet, I think you might be stuck on the difference between face turning and corner turning. The circles will be destroyed if you are doing corner turning Pyraminx /Jing's Pyraminx sequences. You need to do face turning sequences. 2 edges flipped can be removed by applying EPS on 3 bandaged faces (maybe a setup might be needed, but I solve the 3 edges on the bandaged faces last so no setup is needed for the last 3 edges), then reorientating the cube correctly and then placing them with EPS.


Mars Tet: Well.. you can't solve it if it's solved, go ahead and scramble it, are you a chicken :P :lol: ?

Cheers,
Burgo.

Did you try the method in my reply? Do you not like it, or was it not clear enough?
I forget about hidden spoiler. (Turns are face turns!)

If I interpret this sequence correctly, it is a 2-2 swap of corners, right? Burgo is using this as well.

Hi Puzzlers,

I hope not, you put me in frying pan ?

Back to Puzzles. I found:

On Tet Jupiter : flipped 2 edges is equivalent to cyclic permutation of 3 corners.
In other words: permuting 3 Corners or fliping 2 Edges is not solveable without turning the white face.

My solution:
Orient the corners that one face is complete white, than make a 60 degrees turn with white face.
Now its solveable.

(edit) I only use face turning, no vertex turning !!!!!

Cheers,
Andrea

This is not true, as shown by my sequence in the picture above. The 8 moves do a swap of two pairs of corners, which is an even permutation of the corners.
Have you not seen my flipping method in my original response to your question and picture, because it was a hidden spoiler?
When I had seen this kind of hiding a spoiler in the first place I did not understand it as well :)
(My understand was "spoiler" is something on a car :lol: )

The idea is that you have to highlight the text if you really want to read it, but you can abstain from reading if you do not want to spoil the challenge.
As many are reading a post, hidden spoilers are sometimes used.
As we are so few here in Crazy village, we can possibly forget it. :)

Hello Konrad,
I read your text in the spoiler. Ok that works fine.
I see, my posting was wrong. I thought wrong. Thank you for correcting.

Ok swaping 2 eges is solveable without turning the white unbadaged face.

Cheers,
Andrea

Hello Crazy Friends,
Yeah, I solved the mars. For turning 2 corners I found an easy sequence U=unbandaged R and L bandaged.

( R L' R' L ) x 3 (R' L R L' ) x 3 turns the right back corner clockwise
( R' L R L' ) x 3 (R L' R' L ) x 3 turns " " " " anticlockwise.

Longer as the sequences here from the experts but easier to memorize.
The direction of first move is the direction of cornerturning !

I'm searching for a sequence to make a clean 3 cycle of corners.

(U R U' R ) x 2 is a 3 cycle, but the pieces change the orientation.
I found no easy sequencs that makes a clean 3 cycle without changing orientation.

Cheers,
Andrea

Hi Andrea,
Experts :lol:
I just place them and then orientate them after.
If you want to only orientate 1 corner in U, then orientate it along with the one in D.
Don't forget to also use the useful (R'LRL')x3 (with R & L as bandaged) to effectively switch out only 1 corner. I think about it like: what corner do I want to drop out of U, for example if it is LB do a setup move of R' [(R'LRL')x3] R and LB will go to D and then orientate as needed. Remember, you will only need to be `real specific` like this in the last few CCs. The earlier ones you can just bang a few in and hit a few easy ones.
Cheers,
Burgo.

Hi crazy puzzlers

Just wanted to post a mercury tetrahedron corner circle 3-cycle for the 6 or so of you that are still on this thread. :lol:

robertpauljr came up with it and is happy for me to share it. (Actually, there are quite a few variations; I'll post my variation, which I like most)

Hold with the 1 face on down and faces at front, left and right.

(L' R L R') D' (R L' R' L) D (L' R L R') D (R L' R' L) D'

It cycles circle corners FU->DR->DL (along with outer corners).

I love this sequence because, despite being 20 moves long, it's a simple extension of the EPS from ultimate solution and it's super-easy to remember.

[The mercury tet has been my hardest tet challenge, and this 3-cycle made it nice to solve instead of a dread.]

My Neptune Tetrahedron solution

[Spoiler ahead...]

0. This is actually difficult to really scramble properly because once you do a turn or two, you're restricted to turning two faces only. My solution seems a bit silly to me, but it works! I'm interested in better ones. The explanation is a bit cumbersome because this puzzle is a bit cumbersome.

1. Solve inner edges. Use EPS (U'RUR' and variants).

a. Either yellow or white first, then the other of these, and finally the orange and blue.

b. When I can't turn a face during the EPS I re-orient one or more of the offending corners on the face by holding blue/orange as left/right and doing L [(LRLR') x 2] L' [(L'R'L'R) x 2] . This orients UBR corner clockwise and D corner anticlockwise. This is a different view of Konrad's/Burgo's R [(RURU')x2] R' Y [(L'U'L'U)x2] Y' mentioned earlier in this thread.

c. Because of the faces, sometimes you might have placed all white/yellow inner edges and find you only need to do a single 3-cycle of outer edges to complete all edges. If so, see number 2.

2. Solve outer edges. Every solve I've found there's only one 3-cycle of outer edges remaining. I don't know if this must be the case or not. Cycle these edges using EPS the same as above.

3. Reduce corners. Same as for Mars. Hold yellow/white as up and blue/orange as left/right. Position corners (R'LRL') x3 and orient corners L [(LRLR') x 2] L' [(L'R'L'R) x 2)] and turn up face to attach CCs to outer corners. If up face needs a turn to re-solve upper layer inner edges, place 3 corners with same colour CCs on up face and then turn.

4. Solve corners. Use same positioning and orienting methods as above.

~~~~~~~~~~~~~~~~~~~~

Also,

My Unnamed (0012) Tetrahedron solution

Pretty much the same as above.

Only differences are

* it actually scrambles better, due to having an extra 1 face.
* It was harder to get the inner [and therefore all the] edges done (but not much)

On a subsequent solve of the unnamed 0012 tet (I switched the center piece on the blue face of uranus to make it), I tried it a different way and got to this situation:

Everything else is solved. I've found this situation on a few puzzles like this. Does anyone know of a way to flip both these edges? It doesn't matter if corners are put out of place. However, I'm restricted to only turning the orange (2) and blue (1) faces, since any turns of other faces will break up the edges/corners. Any algs or pointers appreciated.

Thanks to robertpauljr & rline for this tip. I used it and it is super slick. At first it looks complicated but when you break it down it is very simple and easy to remember especially if you are familiar with rline's ultimate solution presentation. Check out his website, it's very good. I'm now studying his crazy 2x3x3 series of tutorials.

Burgo helped me through my first solve of the Mercury tet. Thanks again Burgo!

Next up for me are the Standard Tet and the crazy 3x3x5.

Hi!
I´ve got Saturn and Uranus tetrahedron and by combine these pieces I can build them all except Earth.
I have solved Earth (for that one I use the simulator by Bo HU), Saturn, Jupiter, Mars , Mercury and Neptune.
I think that Earth is the easiest. Then Saturn And Jupiter wich is pretty the same and not much harder. The real fun begin with Mercury and Mars. I realy enjoy them. Neptun is even a bit harder and is a marathon in cornerorientation.
The situation rline show above with 0012 is familiar for me when I solve Neptune and it´s realy difficult to sort out. I would appreciate if someone could share an solution on that. I will try 0012 soon.

Hi Crazies...
Just to say that around lots of long hours at work, I have finally attempted all crazy 3x3's!
Yes, you remember? Three whole sub-species ago, before bermudas, tetras and dodecas?
Anyway, as Burgo said, they all have different flavours, some of which I liked and some I did not.
I found Mars and Saturn way to restrictive - the solve would always be the same trail from start to finish.
The best combination of difficulty too pleasure ratio are Earth and Neptune/Uranus I think, so I will be leaving my crazies in those configurations. Now to do Earth by the different methods (as I promised!)

Question: If I were to buy a Bermuda - (I find myself totally disinterested in the Tetras. Don't know why) - which would be the "best" one. i.e. the one that best fits my criteria above.
Thanks in advance.

Hi "crazy" Puzzlers,

My Posting from Mon Oct 24, 2011 1:45 pm. The replacement center piece for crazy megaminx earth arrived.

Thank you Calvin Fan. Good service.

It was difficult to assemble. At the inner centerpiece was a bulge. So i must separate the outer piece from inner piece with power. After that I rasped the bulge a little. But put togeter with the new center outer piece I must do a little power. I must assemble the megaminx in that configuration.
To transform is now badly possible.
But it works.
The earth ist the most difficult crazy megaminx. I enjoy that it works again.

Cheers,
Andrea

Hi Konrad, Burgo and all other "crazy" Cubers,

I cannot buy all puzzles, but I would get one more with circles. Cubes with circles are more difficult than Bermudas, I think.
What about series from Witeden?

Konrad, you wrote that the roadblock puzzle are easy. Ok it's a interesting way to orientate centers.
I own no witeden super 3x3x5 cube. Perhaps the Witeden 3x3x8 type I is a good choice ?
I own no puzzle with only one circle.

The advantage from 3x3x8 to 3x3x5 is that the faces are able to turn 90 degrees.
There exist many types of puzzles. 3x3x7 (I) 3x3x7 (II) 3x3x9, 3x3x8 etc. I own a Witeden super 3x3
The witeden super 3x3x3 is difficult. I think the super 3x3x7 must be difficult, too.
It's difficult to decide which is interesting and difficult enough.
What do you think ?

Cheers,
Andrea

Oh my goodness, Bermudas easier than Circle Cubes? :wink: At least I would not say this about my `cuboids`. I have some without circles (C4U 3x3x4, C4U 3x3x5, C4U 3x3x7, Witeden 3x3x6, Witeden 3x3x9, Witeden 3x3x7 Roadblock, Witeden 3x3x9 Roadblock) and the Witeden Super 3x3x3, 3x3x4, 3x3x5.
Too many puzzles :roll: I have not yet decided if I would go for a Super 3x3x7 or 3x3x8.

Easy does not mean uninteresting or boring. Sometimes I like a puzzle which is not so hard.
It is always dependent which similar puzzles you have solved.
I assume that the Super 3x3x7 and 3x3x8 type 01 (one circle bandaged one not) provide some challenge.

Too many new puzzles to select from :roll:
Why not go for something different like the face turning Starminx? (I have a Mini from TomZ and have ordered the mas-produced version Starminx II = Starminx V1 in TP terminology)

Good luck with your decisions!

Hi Konrad,

Quote:

Yes, I agree. By example the master- skewb is not to hard but a very interesting puzzle.
The aesthetics of puzzle is important, too.

Much fun with the Starminx II. I think it's very hard to solve. there are many pieces in a rotation and in the subgroup crossection of two different rotation possibilities. This puzzle is perhaps to expensive for me. There is no yet mass production ?

Cheers,
Andrea

You can order a mass-produced already. I have preordered a black one for $42 (free shipping) from hknowstore. (The ice purple looks great, but given my experience with a transparent Dayan Gem II I fear that it turns inferior to the black plastic.)

Please, have a look at this thread
viewtopic.php?f=4&t=22574
The name Starminx II is misleading for the experts at TP. The original name is Starminx V1. Gelatinbrain 1.1.5

Somebody with your solving capabilities will find it very interesting, but not too hard :)
There are three piece types only! So, essentially you need to find three move sequences.

I can highly recommend it as a solving experience.
Have you seen TomZ's Multidodecahedron? This is on my wishlist and it includes all dodecahedra at once :)

Back to circle cubes: A real 5x5x5 would be great. (A 1x1x1 core inside a 3x3x3 inside a 5x5x5 and all pieces visible at once.)
It would be incredible indeed!!!! Carl Hoff has described it and Burgo pointed out that Bo Hu's Double Circle 5x5x5 IV is the one.
This puzzle in a physical form would be a dream!!!

Morning All,

I've had a bit of time on my hands over Christmas so I thought I'd break out a puzzle that's been on my `to solve list`.. I solved the Uranus Tetrahedron yesterday :D . The method I came up with is really ugly, but it is repeatable, oh well, gotta start somewhere. I think I am only the second one here, after Schuma to solve it?

Cheers,
Burgo.

Congratulation Burgo,

I own only Jupiter and Mars. One face without circle, the other unbandaged? Is the feeling like Witeden super 3x3x3 ?

Cheers
Andrea

Umm, now that you mention it.. a bit, yes. The one non-circle face blocks like that, but it's much more invasive, blocking up all of the other faces. It was possibly one of the hardest cubes I've `solved`. I had to start from scratch, `no other standard algos were useful`. If you want a solving challenge.. it was difficult for sure.

I have now made a method and have it on a word document with diagrams.. if anyone is anxious to see it just send me a PM and I'll send you a link (I don't think it will be many).. otherwise, give me a few days and I'll check and refine it a bit and post it.

Cheers,
Burgo.

Hi Crazy Puzzlers,

I have the Method for the Uranus Tetrahedron and some sequences for the Neptune and 0012 Tets that ought to help you complete them. I am happy enough with them to post them, but they are a work in progress that I hope will be a bit of a conversation starter. The methods are a bit cumbersome, but that is mostly due to the bandaging of the corners.

Uranus Tetrahedron Method:
https://skydrive.live.com/redir.aspx?ci ... parid=root

Neptune & 0012 Sequences:
https://skydrive.live.com/redir.aspx?ci ... parid=root

If anyone has trouble with the links or format, just send me a PM and I will make a post with it, but it will be without some diagrams.
Cheers,
Burgo.

Now I have solved the Uranus Tetrahedron too. Am I the third? It tooks me many, many hours and now my left hand aches. This is definitely the hardest puzzle I have solved. I will now take a look at your solution Burgo.

Hi Andreas,
Congratulations :D , it’s a good feeling of success to solve it yourself, and it is much better to do that and then compare, so that we can develop something. I solved it a few different ways.. you might notice that my pictures and my final method are slightly different. I have more sequences too, but I had to cull for the sake of a method. I think that we will find better sequences. Thanks for taking the time to solve it, I’m looking forward to your comparison.

Cheers,
Burgo.

Hi,

I have a problem solving my full circle crazy megaminx. I initially tought my solve will be fingers in the nose !
But, close to the end, I have seen 2 inner edges swaped (green and pink)... I have tried to figure out how it is possible ? For me, this cannot happen, but obviously, I am wrong...
Could someone has an explanation of how this swap is possible ?

You mean by full circle crazy megaminx a regular Circle Megaminx, all faces "0" restriction like here, right? The situation on your picture can never be reached by legal moves, because you show two green circle edges in a single orbit. Either somebody has made a bad joke with you or you have swapped them unconciously while turning. My two Crazy Megaminx are so tight that I cannot imagine this on mine.

Hi Konrad,

That's what I tought too ! This is impossible and my puzzle is very tight too.
I don't understand : I was just finishing to rotate the 2 last corners (and everything was ok). After the move, corners were rotated correctly and this swap appeared ! I tried to inverse my moves, but I destroyed everything!! It could not be a joke (I don't think my wife would do this and my child is too young...)
That's a big mystery for me, maybe a 0 face becomes 1 during few moves ?
I have check all faces : they are all 0!
Maybe, I will ask Calvin on how has been done this puzzle.

Hi alacoume,

You are not the first one to have this situation. Back on page 4 Dr Who had the same thing. When the Megaminx puzzles are new and unlubed they are pretty difficult to twist. To the point where some of us have reported broken centre shafts. It is likely your situation has occurred because of a catch and a skip between orbits.

Lube your puzzle well (I use Lubix).
You actually have to keep it fairly firmly tensioned (otherwise the 0 inner circle pieces will begin to rotate with the outer parts).
But the puzzle needs breaking in, careful aligned twisting is recommended during this time to reduce strain on the centre shafts.

All mine are quite nice to twist now, even the 0 faces. My Earth (which I have used the most- it was my first one) is quite noticably better than the others.. it is extremely easy to twist (and the others are getting there with more use). Moral of the story: they take a long time to break in, but when they are, they are truely incredible. I think you just have to watch some of my Earth Megaminx tutorial to see how well it turns.

Cheers,
Burgo.

If anyone can cast their minds back to the crazy planet cubes...

I've been revisiting the circle cubes. I'd like to ask about the need to flip edges on saturn. Reading back through the thread, I think (maybe) Julian posted a way to flip them, Termite said he could do it and Burgo had a method on his video using sune and (I think) the same sequence Termite used. Saturn is the only one of these where I'm stuck. (I'm trying to do them all by reduction). What I'd like to know is:

What is it about saturn that causes this problem requiring the edge flipping? Does anyone else have different ways of dealing with it? Is there a way of setting things up early on so as to avoid the need to flip the two edges? I can now reduce the edges no problem, but I've only been able to solve it when I haven't needed to flip the edges. I'd like to understand what causes it, so I can have a go at coming up with a fix for it myself.

Hi rline,

it's very interesting to solve the crazy cubes after a long time. I remember that flipping edges was a problem. It's not easy. So I separate it to different steps.

(edit) for pairing edges ( layer by layer) the up and bottom faces are unbandaged.


I solve the saturn with reduction method ( I solve all crazy cubes/megaminx with reduction method)
Saturn I solve layer by layer. Pairing one edge with the edge-centers. Then place it.
The down layer and middle layer is easy to solve.

For the last layer I use a "keyhole technique". e.G destroying one complete edge in middle layer.

with F U R U' R' F ' and the reverse I flip edges. 1. flips front and back. The reverse flips front and right.

With the "catch" movings R U' R' U (and mirror F' U F U' ) I pair a edge with the center piece.
It's always possible pair all pieces in this way.

Its possible to do inverted sunes to change front and right paired edges (exclude upper center)
inverted sune R U'2 R' U' R U' R'

Its possible to exchange u/r edge f/r edge with sune( turn cube). This exchanges the complete paired edge.

The 3 cycle F R' F' R is very usefull to place the edge in the hole from middle layer.
If all edges on top have the same color its possible to complete the edges.

After that, I pair Corners with triangle. You can orientate corners with sunes. #
If front and back are unbandaged and last layer is up , it's possible to orientate corners with sunes.
To make a 3 cycle of corners you can use your modiefied CPS. ( E F2 E' CPS E F2 E' )
To permute clean edges you can use sequences that use only 2 adjacent faces.

I hope this helps a little.

Cheers,
Andrea

PS:
All crazy cube planets are solveable in this way.
Only for mercury and venus its necessary to pair edges with triangles.

Hi Andrea

Thanks for your reply.

Quote:

Agreed. It's (relatively) straightforward to actually get the outside edges matched with each of their circle edges.

Quote:
with F U R U' R' F ' and the reverse I flip edges. 1. flips front and back. The reverse flips front and right.

Maybe I've missed something. I was wondering about flipping complete paired edges. But this sequence breaks up my completed edges. I also don't know which faces you have for up front etc., although I assumed up was "0".

Once I have edges placed (after flipping if necessary) I can continue and do the corners no problem. But the big issue for me (and from others earlier), was what to do if you have, say, the UF edge completed but inverted, and the FR edge completed but inverted, with all other edges completed and placed.

On a normal rubik's cube if I encountered this, I would simply do something like R' F R F', which would take the edges out of position, and then put them back doing R U' R' U. But of course on saturn I can't turn the U face without breaking the completed edge.

I have answered one of my own earlier questions, which was "What is it about saturn that causes this problem requiring the edge flipping?" and I realise it's nothing special, it can happen on other planet cubes, it's just that we can easily get around it.

I guess now I'd still have two questions

1) Is there a way of setting things up early on so as to avoid the need to flip the two edges?

2) With the scenario above with my two flipped edges in UF and FR, what would you (Andrea) or others do to deal with that.

Any and all comments are welcome.

I had found a pretty complex method for solving the last 1 layer myself.
Since I read Julian's post on page 2 (Mar 14, 2011)of this thread http://twistypuzzles.com/forum/viewtopi ... 80#p251280 I prefer his method
Quote:
I think it is easier to finish the Saturn edges with a 1 face last layer. I solve a cross of circle edges, then the other circle edges using Fused Cube algos where R is a 1 face, leaving the 4 outer edges to last. Where R is a 0 face, I permute 3 outer edges with R2 U R2 U2 R2 U R2, and swap 2 outer edges with R2 U R U R' U' R' U' R' U R' U'. The outer edges at UL and UR can be flipped with (B' R B) then the edge swap then (B' R' B).

Hi Konrad

Yes I saw this also. I read the first 3 pages of that thread just the other day. Perhaps that is the only way to do it (not being able to move around the completed edges successfully). Perhaps it's best to break the edges and move around outer edges. I don't know. I just figure that since you found a (complex) way to move them without breaking them, as did some others, there must be other ways also. I suppose if we break them, then it's not truly a reduction solve, is it?

It is one of the critical problems of the puzzle, no matter `when` you tackle it in the solve you will have to overcome it (or `how` you tackle it- you might choose to make inner edge 3cycles instead, for example). You will always have to deal with it in one way or another.

rline wrote:

You need to reduce it to a solvable state: With Saturn it is not possible to flip a reduced edge later without breaking a relationship, so you need to do more than `just reduce it`. You need 3 adjacent turnable faces (around a corner) to flip a reduced edge.

The general consensus so far has been to place these pieces in a `last layer` approach because that groups them together into the most condensed patterns (or state), making it easier to manage visually. You must know you can’t flip them without breaking them, or you wouldn’t be asking the question.

ANOTHER EDGE STRATEGY for Saturn:

You can solve the outer edges first. (Outer edges by themselves are simple, inner edges by themselves are simple, together is the issue).

You can then use standard edge reduction with one constraint: only 180* turns of yellow or white faces are permitted: this won’t change the orientation of any edges. (Edge placement is not necessary).

You will begin to encounter problems where you need to do 90* twists: to overcome this you can use any `inner edge 3cycle`: [white or yellow as U] [(M’U)X3 U (MU)X3 U]X2 for example moves FU > UF > BU. This will break your deadlock without flipping any of your edges. You can then continue with simple reduction or the `inner edge 3cycle` until the edges are reduced and they will be solvable.

There is no need for `setups and undos` with this method, which was the issue with how I presented it earlier.

Cheers,
Burgo.

Ah right. This is very helpful to know. I asked initially because there are some puzzles (eg. rex or master skewb) where if you setup the corners at the start and then do only even-numbered sequences you can avoid dealing with "parity" things later. I thought the saturn might have been like that. Apparently not...

Quote:
ANOTHER EDGE STRATEGY for Saturn:

And this is the thing that interests me with saturn now. I already have a CCL strategy where this edge flipping issue didn't arise, or at least was dealt with in a different way. I've been trying to solve saturn by reduction. What has helped is to be reminded that reduction means reducing to a solvable state. So even though I've matched the edges, I haven't yet "reduced" the edges because it's not solvable.

This seems quite an interesting approach. I've had a look at this and from memory tried something like it myself a while back but didn't think it'd take. So an approach like this: can it still be called a reduction method?

Alright. So would the general consensus also be that the easiest way to deal with this approach is to use what Konrad quoted above from Julian?

I've just solved neptune by reducing to a standard cube and also by reducing to a circle cube. These cubes are amazing value for money. :D

I think you are perhaps being a bit pedantic with the term `reduction`. It `essentially`means to make the puzzle into a simpler puzzle, and then `solve that simpler puzzle`, rather than to solve it by layers or piece type. The method I've outlined above is reducing it. I hope you can see that I am only using the inner edge 3cycle minimal times, to fix the orbits created by making only 180* twists of the 0 faces.

In fact it's so easy that way that I think it's got to become my standard method.. Shame, I liked the other method.

rline wrote:

Yeah, I think it would be the `easiest` form of that LL edges method. It's the same as my LL edges method but with one more step that breaks `one thing I am doing into 2 steps` that makes it a bit easier to understand and perform (I orientate the top layer in one go, whereas he orientates the inner, and then outer edges seperately). I think it's really going to be up to individual preference though.

In Julian's method you use [R as 0] FURU'R'F' to orientate inner edges (it 3cycles FU>UB>UR). And then (as Konrad said) I would use [R as 0] (BL'B') RU' RU RU RU' R'U' R2 U (BLB') flipping UL & UR, and [R as 0]Sune to cycle outer edges into position, but the key is the 3 move setup, and this allows the seperation of inner and then outer edges in the solve. You still need to use all of the other edge cycling with Sune [R as 1 and 0] after LL orientation.

Cheers,
Burgo.

I had founded a little trick.

1) assume that the upper layer is red and unbandaged.
2) the upper right and front right pieces are flipped. right face is yellow.

3 bring the correct edge piece to the front. This is always possible with sunes.

It doesn't matter which colors. Important is, that the upper face is unbandaged and the 3 pieces must have the colors around the front right up corner.



do ( F R' F' R) x 2

after that the 2 inner edges of upper face have the same color.

make a inverted sune. R U2 R' U' R U' R' U'

do ( F R' F' R) x 2

after that , all pieces had the correct color on upper face. To exchange u/f with u/r do

R U2 R' U' R U' R' U'.


This trick is always possible.


Explanation: The easy edge 3 cycle changes the position and orientation of 3 complete edges around a corner. Perhaps for the mirrored case you must repeat the 3 cycle.

The case that two equal colors are in upper face is always included. The permutation of 2 edges is equivalent to the flipping of 2 edges.

Andrea

Hi Andrea,
Could it be that there is somewhere a typo in your sequences?
I just performed your sequences on a normal 3x3x3

1. ( F R' F' R) x 2
2. R U2 R' U' R U' R' U'
3. ( F R' F' R) x 2
4. R U2 R' U' R U' R' U'.
This changes five of twelve edges (which are outer edges on the Saturn) and the 3x3x3 looks so much scrambled that I could not see where this would help solving the Saturn.

Hi All,

I have made a quick Youtube video to demonstrate my new edge reduction that I talked about ^^. Just to make clear what I am doing:
Saturn Edge Reduction (new version)
http://youtu.be/QEqLphIZnHE

Hi Konrad and Andrea,

I didn’t try Andrea's algos because I couldn’t tell how she was arranging her edges around a corner: a diagram or photo would be good Andrea. But.. I could tell what she was doing:

She is using a Sune to move edges on a 0 face. Where the three edges in the cycle have the same colour on U: the 3cycle will move 2 at 90* and 1 at 180*, so the 2 that travelled 90* will effectively be flipped. This is useful but I expect it would be difficult to set up for (assuming you have just done a Jupiter style edge reduction where any number of edge pairs might need flipping). And it needs to be done in an order that meets the requirements of: 2 edges with the same colour that need flipping plus a dormant edge of the same colour. It’s a clever idea, thanks for sharing it Andrea.

Cheers,
Burgo.

I made a little bit work. I use screenshot, windows paint and gimp and my simulator. ( I have not enough praxis with gimp)

Solving Crazy Cube Saturn

In this example white and yellow are unbandaged, all other are bandaged.
Upper face yellow right face red , front face blue.

To the right up front face belongs yellow red and blue.
So the front up edge must have yellow and blue.
In easier words. The upper front edge must be solved.

the f/r and u/r edges are flipped. Marked with the number "2" and "1"


The corner with the number "3" belongs to the yellow/red/blue corner, too.
In the simulator you can see the last done sequence.

Now do the edge 3 cycle around a corner (r/u/f corner) : ( F R' F' R ) x 2

Now the upper faces of edges are equal. Marked with X !

do the sune. ( exchanging the 2 edges marked with arrow)

Redo the 3 cycle ( F R' F' R ) x2

Last step: exchange the two eges ( marked with arrows) with a last sune.

And ready !

Sorry, I 'am not able to describe it better. I f this is not understandable , perhaps I must give up.


Cheers,
Andrea

This trick is easy. It works always with every crazy cube ( exclude mercury, venus).

Perhaps you must do the 3 cycle two times.
The arrange of edges dosn't matter because there are always 2 possible equal colors.

Restriction: you must solve the first two edges with a different method. ( by example with a combination of catch moves e. G. R U' R' U and variants and sunes.

Disadvantage:

This is difficult on Crazy Megaminx because there it is not possible a sequence that only exchanges 2 edges.
On Megaminxes I use this technique, too. Because I know nothing other. Most difficult is the crazy megaminx earth.
