Hi Burgo!
I solved Uranus 2 layers. Top layer is blue.
What is your corner orientation method for top layer?
At me an inconvenient method..

I will use a hidden spoiler that you have to highlight with your mouse (because I think some people will not want to know this yet):

Hidden spoiler:
[ There must be a Y pattern of corners and edges, so let's use Blue U, Yellow F.
Let (R'FRF')x3 = v
Let (RU'R'U)x3 = >
Let (F'UFU')x3 = <
Some orientating sequences are:
v > < = 3
v > v > = 4
v > v < v = 3
v > < v < > v = 2 (this was the situation I had at the end)
]

Just try them out on a 3x3x3 to see the patterns, like I said I haven't spent much time on making them perfect, it's just my notes, nothing comprehensive (I see this as just a conversation with friends towards similar goals). Once you see the method, you can make up some more too :D .

Cheers,
Burgo.

PS I am wondering what the colour scheme is on the white cubes (the same as the black cubes, but with black instead of white stickers?). I say this because the planet stickers are on the green face, and there was some confusion about not being able to do sequences?

Hi Burgo and all together,

congratulations to solve uranus and saturn. You solved all 8 cubes ?

I am not so fast. I will try to make a video for neptune. Then I will take mars. I'm slowly. I want no battle. ( then I would be a speedcuber) I want fun with puzzles. So I analyse a cube and then go to the next.
To analyse and share know how is my intention here. I want not brag.

Some sequences I found for Neptune:
I post only 3 of it.

R, U , B are trianglefaces.

(R' U R U' z x') x 6 turns CLEAN 3 corners in the right face.
Turns each corner counterclockwise.

(R' U R U' z x') x 9 flipp CLEAN 2 edges in the right face.

Turn 2 Corners clean. R, F and D are trianglefaces.
Turns the f d r corner counterclockwise and the
b r d corner clockwise.

R F' Sune R U R' U R U2 R'
U' Sune R U R' U R U2 R'
U2 Sune R U R' U R U2 R'
Left Sune F' U' F U' F' U2 F
Sune R U R' U R U2 R'
U F R'


This is a mistake, sorry
Corner 3 cycle ( from posting befor)
R L' (setup)
U' ( R' L R L') x3
U ( R' L R L') x3
U ( R' L R L') x3U'
This sequence is useful.

(edit) an error occurs
Correction:
Corner 3 cycle ( from posting befor)
R F' (setup)
U' ( R' F R F') x3
U ( R' F R F') x3
U ( R' F R F') x3U'
This sequence is useful.

replace L with F



Last but not least:
F R D = triangles

(R L' R' L) x 3 ( CPS)
exchanges r u f <=> r d f
and f l d <=> r b d

Perhaps this sequences are needed to solve the neptune with a sure concept.


It' difficult to choose sequences for teaching this cube.

Cheers,
Andrea

Hi Andrea,

I have not solved all 8 yet, I am solving Saturn still. I am on the LL which I am using as the red face. I think it will be difficult because the white/blue edge is the non-scrambled edge on this one (and it's in between the `2 cubic faces`), so there is no LL that I can use as a `cubic face`. I have a few things that I am trying, but.. I'm not sure yet.

I'm not trying to race either, I don't think there is credit for that. I just like to get a general idea for all the types of puzzles in the series before I commit to a `method`. So I don't want to dedicate too much effort to specifics too early, I will instead come back and solve them all again with a clearer idea of the big picture. (I also get a bit addicted to see what the next one is like :wink: ).

I will also go back and have a closer look at everyone's methods then too.

Did you notice my modded fisher cube on the previous page? It's my only mod I've ever done, I know it's not much but no-one noticed it :( ?

Cheers,
Burgo.

Hi Burgo!
Thanks for your corner-orientation method. It is very useful knowledge.
I at first have chosen other way of solving, but now I see that your way is more convenient.
But this way I will use only for Uranus and Saturn because I solve other cubes absolutely in another way.
And I want to ask as you premutate corners?

Oh, sorry. I read that posting directly after you posted it.
Your posting from Thu Nov 10, 2011 1:48 am ?
I'm afraid to disassemble my puzzles.
One difference between the fisher-cube with triangles and bermuda cube is, that the centerpieces have 2 faces and the edges have one face.
I cannot modify cubes in that way that the core-axis connect edge pieces as centerpieces. So I don't answer to this posting, but I read it.

Win discusses only with you. I have no reply to my sequences. Perhaps they are to difficult or awkward. So I get no reply how usefull this sequences are.
Thanks for your answer.

Cheers,
Andrea

Hi Andrea,

This is how I modified it, it's just one small cut and some glue for 4 pieces. It made a very interesting little cube because it adds orentation to the Fisher E-layer edges too. For your sequences, I will try them all on the weekend.

I just found the way to solve the Saturn also :D . I ended up using the green face as the U layer, it was better.
When you say premutate: I think I know what you mean, here is the order:
When 4 corners & 3 edges are remaining in the Y pattern.
1) EPS (R'FRF') sequences to place and orientate edges.
2) EPSx3 sequences to place corners
3) Then my corner orientation sequences^^
Correct?

Cheers,
Burgo.

Hi Burgo,

Your modified Venus.
Great work !

Turns it well? Is it hard to solve? You must find sequences to orientate centers , now edges.

Cheers,
Andrea

No, it's not a modified Venus Bermuda: it's only a [Fisher cube + 3x3x3-E layer], I made it a few months ago.. It's only `like` Eitan's unusual version of the Venus Bermuda (the same thing was done to that Bermuda). But thanks for liking it :D .

Hi Bermuda Cubers,

I made a Neptune Video.

http://www.youtube.com/watch?v=epyHqVaFFOM

I tried to use easy sequences. Perhaps the video helps someone.

I solved all planets bermuda cubes!!!
Thanks to Burgo for corners orientation method. I used this method for ending of solving Uranus and Saturn.
In my opinion Uranus and Saturn - the most difficult planets.
But they solving absolutely equally, though Saturn it is more interesting.
I can publish a principle of my decisions if it is interesting.

I used my Mars method to solve Neptune.

I do it vice versa.
The mars:
After building blocks I solve the green/red piece with intuition.
Then the red/green/black corner. For the green/black ( or white) I bring the slot to U and use a sune/mirrorsune combination like in neptune method.
I prefer the sune+mirror-sune method to make a clean 3 cycle now.
Now only the orange layer is unsolved. First i flip the edges.
The corners I permute with the same sequence from neptune. The permuting of edges is like neptune solution. Orient the corners with simple sunes.
One difference is flipping the edges.
This sequence does it:
( front blue up = orange) L F U F' U' L'

Mars is a little bit easier than neptune, I think.
I must now solve the jupiter, saturn and uranus.
Saturn and uranus are the hardest, I think.

Cheers,
Andrea

Hi Andrea,

Did you see my Sune & Mirror-Sune method for orientating 2 corners too?
You have to do a U' turn in between to do it with the R&F faces.

Cheers,
Burgo.

Hi Bermuda solvers,

I forgot that I hadn't placed any sequences for Saturn because it was the same as Uranus, so I will put down the method:

Uranus is: Blue as U, Yellow as F.
Saturn is: Green as U, Yellow as F.

To turn Saturn into Uranus perform (RR+) (U'U-) on the standard shape.
So according to this I solve the yellow and orange blocks, then the Green/Red/Yellow/White (3 piece block), then the Red/Yellow/Blue (3 piece triangle). This leaves the same Y pattern as Uranus when the cube is converted.

Saturn and Uranus method for last part:

1) EPS (R'FRF') sequences to place and orientate edges.

2) EPSx3 sequences to place corners
*Converting a 3+1 corner swap to a 2+2 corner swap requires including another corner.
Let (R'FRF')x3 = v
Let (RU'R'U)x3 = >
Let (F'UFU')x3 = <
And I will call:
(FF+) U (F'F-) U' = get
U (FF+) U' (F'F-) = replace
Corner 3 cycle for 3+1 > 2+2: [get > replace > get v > replace]

3) Some orientating sequences are:
v > < = 3
v > v > = 4
v > v < v = 3
v > < v < > v = 2
Combinations of these will be all you will need.
(Just try them out on a normal 3x3 to see the patterns).

Hope that is clear enouugh.
Cheers,
Burgo.

I am very confused right now. I ordered a Venus Bermuda Cube, but what I got is not the same as the puzzle in Andrea's video. Her cube has a middle layer that is like a 3x3. Mine has a middle layer like a Fisher Cube! The parts attached to the core (the centers) look like 3x3 edges on the outside, and vice versa. I have attached pictures.

Has anyone else seen this happen?

Thanks Vladimir Yaroslavskiy letting me know about the discussion here about the Venus mechanism, 3x3x3 cubic style and fisher style.
I had checked with Mr. Dayan about it. He told me that only the 1st batch of Venus and Mercury are 3x3x3 cubic style, 20 pcs each types, the rest are fisher style.

There are 2 ways to assemble the Venus and Mercury, 3x3x3 cubic style and fisher style. Due to lack of Rubik's center parts, the factory changed the Venus and Mercury into fisher style.
The latter ones actually is more challenged as there are center orientation issues when solving.

PS: those who bought Venus and Mercury in 3x3x3 cubic styles ( only 20 each ) in the 1st batch order are lucky, these are the most unique !
Cheers. ^^

Hi again,
I am the only one working tonight I think? Just a quick note:
I solved Neptune again, but I used the Method for Uranus, it suits the cube much better to solve it like this.

After building the 3 blocks:
1) Red Front, Green U (and set the cube up with B R2).
2) Place red yellow edge, pace on top of yellow centre and perform R2 B2 D (L) D' B2 R2
3) Build the rest of the Red/Yellow/Green [corner+ 3 edges] however you like, I used sune & EPSx3.
4) Return the cube (R2 B') and reorientate the cube so that the triangles are on UFR (I used Blue U, Orange F).
5) Solve the remaining Y pattern as for the Uranus & Saturn mathod.

Cheers,
Burgo.

So cubes in the solved kind will look

Solving Mercury, Venus, Earth, Mars, Neptune, Jupiter

1. Solving f2l

At this stage cunning will help, which consists in at first to solve packs from 3 parts which are necessary for putting on the long party of the triangular center. It becomes on the top layer and then is put on the place.

2. Permutation corners on the top layer

For clockwise permutation 3 corners (ULB-UBR-URF) use F (R U’ R’ U’ R U R’) F’

3. Orientation edges on the top layer

For a turn of a forward and right edges use F (R U R’ U’)*2 F’
For counter-clockwise permutation left, right and back edges use R U R’ U R U2 R’

4. Orientation corners on the top layer

For clockwise rotation 3 corners use R U R’ U R U2 R’

5. Permutation edges on the top layer (a, b, c, d)

For clockwise permutation 3 edges (UF-UL-UR) use (R U R’ U R U2 R’) y (L’ U’ L U L’ U2 L) y’

5. Permutation edges on the top layer (e, f)

For clockwise permutation 3 edges (UF-UL-UB) use (F (R U R’ U’) F’ U)*8 U’ y’ (R U R’ U R U2 R’) y U’

Solving Uranus, Saturn

1. Solving f2l (except corner FRD) + the triangular block consisting of 3 pieces of the top layer

Solving edge DL
Solving back triangular block
Solving right triangular block
Solving front triangular block
Solving top triangular block

2. Solving edges FR, UF, UR

Use move like R’ F R F’ for permutation and orientation edges

3. Permutation corners FRD, URF, UFL, UBR

A) For change FRD-URF and UFL-UBR use (R’ F R F’)*3
B) For change FRD-UFL and URF-UBR use (R U’ R’ U)*3
C) For change FRD-UBR and URF-UFL use (F’ U F U’)*3

4. Orientation corners

For clockwise rotation corners FRD, URF, UFL use A+B+C
For clockwise rotation corners FRD, UFL, UBR use A+B+A+C+A
For clockwise rotation corner UBR and anti-clockwise rotation corner UFL use A+B+C+A+C+B
For clockwise rotation corners URF, UFL and anti-clockwise rotation corners FRD, UBR use A+B+A+B


After complete solving necessary to make upside-down the setup moves

p.s. Thanks to Burgo for help in p.3, p.4 of Uranus and Saturn solving!

Thanks for your post Win712,

It is funny to see some of the setups from different angles :D .
I see what you have been trying to do.
I have been working on taking some of the `visual awkwardness` out of my methods. I am getting happy with them now.

For example on Neptune I was approaching it with a setup similar to yours, but I didn't like it much. You should look at my newer way for doing it^^. It suits the cube much nicer.

Quote:
(F (R U R’ U’) F’ U)*8 U’ y’ (R U R’ U R U2 R’) y U’
You don't need to do this, I would do almost anything to avoid using this. Why do you need it? I think I was using Andrea's (R U2 R' U2)x6 in this situation and including the front right edge, it is very fast to perform. Just do 2 opposite edges in the U layer first, by inserting the wrong one first and then pushing it through for 2 opposites correct, the last 3 will then go in.
Quote:
F (R U R’ U’)*2 F’
At first I didn't understand the purpose of this? Why not just use FRUR'U'F'? But now I see you have done corner permutation first and are tying to preserve it. A nice work around.

Quote:
F (R U’ R’ U’ R U R’) F’
I think this one needs a U' at the end?
Is it OK to ask those questions?

Cheers,
Burgo.

Thanks for comments.
At the solving of cubes I tried to use the most known methods. In spite of the fact that after my setup moves the cube looks inconveniently, but it gives the maximum freedom of movements at the cube solving.

VENUS

I will elaborate on and clarify my Venus method:
It is an edges first method.

1) Orange block - Red block (intuitively).

2) With Yellow as F, blue as U: you can place all edges easily with L F L' or L (R'FRF') L' turns or M U M' etc and sune for the U layer.
To flip 2 edges, in UF & UR: RUR'U' L R'FRF' L'

3) Place corners with (EPS)X3 variants:

(U'RUR')x3 = FUL<>FDR + UFR<>UBR
L (R'FRF')x3 L' = UFR<>DFR + UBL<>UBR
[y2 (L’L-) U (L’L-)] (UL’U’L)x3 [(LL+) U’ (LL+) y2] = UFR<>DFR + UFL<>UBR

And a corner 3 cycle (U'RUR')x3 U’ (U'RUR')x3 U [y2 (L’L-) U (L’L-)] (UL’U’L)x3 [(LL+) U’ (LL+) y2] = URF > ULF > ULB

Another handy sequence is a U layer X-pattern 2+2 swap (U'RUR')x3 [L (R'FRF')x3 L'] (U'RUR')x3 = UFL<>UBR +UFR<>UBL

4) (CHANGE CUBE POSITION) Change cube position to: Red as F, Blue as U.

Orientate 2 corners (orientates BL & BR) so a setup may be needed.
(F’F-) U' Sune U2 y2 Sune-mirror U2 y2 U (FF+)
where (sune=RU R'U R U2 R') and (sune mirror=L'U' LU' L U2 L')

I hope that is more usable than the notes I made before.

Hi Vladimir,

In spite of the fact that after my setup moves the cube looks inconveniently, but it gives the maximum freedom of movements at the cube solving.
Yes, for sure, that’s what I meant when I said `I see what you are trying to do (or what your goal is)`. I think my approach might appear cumbersome, but for me it is a variant of what I already like to do. It’s nice to have a conversation and compare our approaches. Don’t worry, I don’t intend to criticise anyone’s preferences or methods, diversity is excellence.

Thanks to a suggestion from Andrea, I decided to solve Jupiter in a Neptune format (by using the setup moves Blue F, Red U: [R2 (U'U-)])

1) Solve the White and Blue blocks.
2) Solve the White, Orange, blue&Green 3 piece cubic block.
3) Align them all and orientate cube with [Yellow F, Green U].
4) Solve the Orange, Yellow edge. The following positions and orientations are acceptable for the edge, (the orange sticker is in the brackets):
U(L), (U)B, (F/D)R, [U/F(R)+extra D turn] Setup for one of these with sequences from vv (step 5).
Sequence= B2 (R'R-) B' D (L turn/s) undo.
5) Build Orange, Yellow, Green (corner & 2 edges):
Setup= B2 (R'R-) B R2
Sune
2 edge flip= y FURU'R'F' y' (Use Red F, Green U).
EPS & (EPS)x3
6) Restore the cube, reorientate with [Blue F, Red U], and apply the setup [R2 (U'U-)].
7) Finish Y (Solve relative to Neptune and Uranus):
EPS to place edges. (I haven't got an edge parity yet but I see one is possible. If you get it you will need to go back and Re-Solve step 5 with the Green centre 1 turn around).
(EPS)x3 for a 2+2 corner swap.
[get > replace > get v> replace] for a corner 3cycle. Complete sequences and explanation ^^ above.
Corner Orientation = (EPS)x3 sequences like: [v > <] Again, complete sequences and explanation ^^ above.

I think I like doing it like this better, it is at least more visually acceptable to me.

Cheers,
Burgo.

Hi People from Bermuda Island,

my experience with Uranus.

The green face is never turnable.
The red face, too.

=> so the red/green edge never leaves his place.

Ok no problem. I think its not possible with easy sequences do a corner 3 cycle. ( CPS ).
This needs a face without triangles. But the faces without triangles are not turnable.
So I tried to solve the Uranus, but the nightmare comes.
The corner 3 cylce parity nightmare. :( :( :(

May someone of the experts help me with a little sequence ?
please! :) :D

Hi Bermuda Cubers,

Solution as accident !

It's possible to destroy / resolve 2 triangle blocks. Then the probability is 50% this situation is away. I solved the Uranus in this way. :( :oops:
But it is not a solution for me.

Cheers,
Andrea

Hi Cubers,

No one founds the solution, so I must self search for it.
I found a therapy against the parity nightmare solution for Uranus !

The sequence : ( it's long)

3 cycle for Uranus
F= yellow
U=blue

U' R'R- U RR+ (R' F R F') x 3
R'R- U' RR+ U R U' R' U
F R' F' R'R- F'F- RR+
FF+ R F R' FF+
R'R- F'F- R'R- F'

(EDIT) and (UF'U'F) to restore edges and corners , thanks Burgo.

Ohh, it looks harder than it is.

The idea is:
1) Bring one little corner to the cps position.
2) make cps. ( Corner Piece Series exchanges f l u <=> r b u
and f u r <=> f d r )
3) bring it back with a different way.
Thats all.

If after this 3 cycle the corners are wrong you must repeat it.


Additional sequences:

Turning corners ( same as Neptune)

F= yellow
U= blue
Orientate the corners:
(R' U R U' z x') x 6 turns CLEAN 3 corners in the right face.

Orientate the outer 3 corners:
((R' U R U')x2 z x') x 3


Much fun with Uranus.

Cheers,

Andrea

Hi Andrea,

I have posted my method for a corner 3cycle on Saturn or Uranus, thankyou for posting your method, I am interested in what others are doing too.

You might want to put (UF'U'F) at the end of your sequence to return the edges.

Burgo wrote:
Uranus is: Blue as U, Yellow as F.
Saturn is: Green as U, Yellow as F.
To turn Saturn into Uranus perform (RR+) (U'U-) on the standard shape.

*Converting a 3+1 corner swap to a 2+2 corner swap requires including another corner.
Let (R'FRF')x3 = v
Let (RU'R'U)x3 = >
Let (F'UFU')x3 = <
And I will call:
(FF+) U (F'F-) U' = get
U (FF+) U' (F'F-) = replace
Corner 3 cycle for 3+1 > 2+2: [get > replace > get v > replace]

I am also interested in what others have done for a pure 3cycle of corners in Saturn and Uranus. I have posted my method^^.

Cheers,
Burgo.

Yes, thanks.

I looked at your method after I found my own. The method of changing 1 piece in the CPS is brilliant. I used it to generate the 3 cycle for Neptune and Jupiter, but in the way on no shape shifting.

On Uranus it's not possible to make a 3 cycle without shapeshifting. So I called it parity ( like square-1), although the numbers of permutations is even.

Your solution for 3 cycle is more systematically and shorter than mine.
The choice of your symbols v < > is good.
Congratulation. Great work. I will try to use it.
Thank you for your posted solution !

I suggested that Jupiter can transformed in a Neptune, but I said that I don't use this technique. It's difficult to build visuality 'wrong blocks'.

So I must try to find a new solution for Saturn. My intuitive building blocks method perhaps is to hard for solving 'wrong' blocks.

Cheers,
Andrea

I think the Jupiter /Saturn conversion is the most visually acceptable of all of the Bermuda `conversions` that I have tried. I have found alternatives for all of the other bermuda cubes, to solve them in the normal configuration. But I think I am happy enough with this one solving it edges first you can easily see where the corners belong:

Hi Burgo,

for Jupiter I use a directly cube solving system. For Saturn this is perhaps to difficult. So I will try to solve a transformed Uranus.

Your right picture. If you add R'R- UU+ RR+ U'U- ,
then you get a symmetric cube. This is easier to memorize. You can build the triangle blocks of thinkig you have an Uranus.

Today, I have received my Bermuda set :)
I solved Mercury so far and found it pretty challenging. Due to the Fisher style (Calvin explained that only the first 20 were made with cube centres) it seems a bit harder than the first version. It exposes orientation of four centres as on the ordinary Fisher Cube. Seems that there is no equivalent on Bo Hu's simulator

Hi Konrad,

I enjoy with you that your Bermudas arrived.

The long waiting time has the advantage, that you get the very interesting fisher-style Mercury and venus. I ordered to early, so that I got the old versions :( :(

Pleas, tell us your experience with your Bermudas.

Cheers,
Andrea

Today I solved Venus. I have to say that I found it really challenging and the Fisher style adds two things
: orientation of the four "Fisher centres"
: considerable `dazzling` factor (OK, this will improve after a few more solvings)

As I have not yet looked at any details of other solutions, I'll just outline briefly my way (I think Andrea and Burgo have posted a lot about the more difficult planets, maybe some details about Mercury and Venus, too. Aaah, I recollect that Andrea has made videos about Mercury and Venus.)
1. solve the two blocks around the orange and red triangles
2. sole edges taking care of the centre orientation as well
3. solve corners with 3-cycles of the three ordinary corners on the orange face

OK, I ended up with this orientation problem of two corners

Image

I have not yet found a way to orientate those two adjacent corners in a pure way.
Now, I changed my plan and orientated the two by breaking some edges and centre orientations.
So, my first solution would be better described as
2. corners with 3-cycles and orientate them by combining Sune and Antisune
3. edges and centre orientation

My verdict about Mercury and Venus Fisher style: In my view, quite a bit harder than the first version with Cube centres. I would have liked the training with the Cube style puzzles better, before I go to the harder planets. :wink:
Andrea and Burgo, you might want to consider buying at least Venus in Fisher style :wink: :)

BTW, it will take me a while before I go the next, because I have cut down my puzzle time considerably. (I have a house and a family, too. :roll: )

I had a first look unto Earth today and I checked Bo Hu's simulator.
As alaskajoe has mentioned Earth is solvingwise identical to "two triangles on adjacent faces #2"
The colour scheme and the missing Fisher face (orange on the physical puzzle) let the simulated Bermuda look quite differently from the physical Earth.
Is there a programmer out there who could fix the applet? :)
I had intended using the simulator for diagrams, because it is easier than taking photos all the time.
And it is less dangerous if I screw the puzzle up while searching for new move sequences :wink:

It has already been done one month ago in Bo Hu's simulator ;)

http://twistypuzzles.com/forum/viewtopi ... =1&t=20285


With the page I posted it's easy to change the colors editing the html as I said.

But I should have said "all bermuda cubes possible with Bo Hu simulator".

And actually two cubes were missing, here is the page with them too.

Thanks bish and marcom for trying to help. :)
I'm not the big expert in Java, but as far as I understand the problem is a bit more subtle.
I have a version of Bo Hu's Simulator back from August 2011.
It offers 28 types of Bermuda Cubes but as far as I can see, none of them is identical to the physical Earth Cube.
This is the net of Earth.
Image
If I choose "two adjacent triangles #2" and do a setup turn of the red face I get:
Image
Now, I need two more things:
U has to be in Fisher style and the colour scheme (after the setup) has to be changed.
Image

As far as I can see, the bermuda.htm (the original and the one from marcom) allows to choose one of the 28 types and I could change the colour scheme of these. But I need a different type to have one identical to the physical Earth. The 28 types are programmed in the Java applet itself (things like Fisher Faces, setup of triangle faces), right?

Or what am I missing?

BTW, Earth is the third Bermuda I'm going to try. The physical Mercury and Venus seem to have no exact correspondence in Bo Hu's simulator, as well.
If it is not too much work, I would really appreciate, if all specified Dayan Bermuda planets would be supported by the simulator.

I know this probably only means something to a limited amount of people, but I recieved my new Fisher style Venus today and scrambled it..
It was actually tough to scramble compared to the first type, because I was not used to the format. I am finding it completely different.
I actually wish now that I had the foresight to order the new ones in white so they would look different.
And this photo is for those who have the old version to consider..
I have also ordered the Mercury, Column and Star. Mainly because I was interested in the way centres are used in this deceptive way.
Reminds me of the mixup cube, and it must introduce an edge flipping parity problem :D like the Fisher's cube.
Cheers,
Burgo.

I had started investigating Earth when Ayi's 5x5x4 arrived. That distracted me for a while. :)

I am bit intimidated by earlier comments about the `beast` Earth, so I have not yet scrambled the physical puzzle. Instead, I searched for some sequences using Bo Hu's simulator.

I found it confusing that the simulated puzzle (two adjacent triangles #2) does not correspond to the physical puzzle (as I mentioned in my last post above). I would not need this additional confusing factor on top of confusing Earth :lol:
The big advantage when searching sequences using a simulator is the Reset button :lol:

Anyway, I have documented for myself the corner and edges sequences I came up with so far (Some are obvious, but the pure 3-cycles corner in 12 moves occupied me a while. I could not find anything close to the usual CPS commutator for a 3x3x3 - e.g. U R U' L' U R' U' L)
I want to share the diagrams with my fellow travellers to the Bermuda triangle :lol:
The results of the sequences are achieved starting with the start configuration configuration in the first diagram.

I have not yet looked at other solutions in detail, but I have seen different notations for the 45 degree turns. I decided to use Anrea's + -
The move sequences use 90 degree turns anyway.

Hi Konrad,
Thanks for your post.
I was also distracted by Ayi's 5x5x4 :lol: (it was nice, but I used the same method as the 4x4x5).
I didn't like the simulator with these puzzles, I don't like when you click and nothing happens, it's distracting, I prefer the resistance of the blocked physical puzzle. I also didn't like how it made a 1/2 turn all the time, that was frustrating.
You should scramble it and make a start, it's fun that way :) .
I just sat down and solved my `new` Venus Bermuda, it is a lot harder than the other version I think, with the confusing factor.
I put on a photo of an interesting looking part of the solve (maybe it will show how much fun these Bermudas are) :D .
Cheers,
Burgo.

OK, I have scrambled and solved Earth. I'm proud but a bit exhausted. My move sequences above were sufficient, though. The main problem was the `dazzling` factor.
I need a more relaxing puzzle now before I try the next. A Starminx would be nice :lol: (My Mini catches a lot and that isn't really relaxing. :roll: )
BTW, what do you recommend next? (Not much harder than Earth, please! :wink: )

EDIT: I scrambled and solved Earth once more. That was much less confusing.

Hi Konrad,

Quote:

I'm not Burgo , but I want to answer.

You solved Mercury,Venus,Earth. Good sequence.
Earth, Neptune, Mars,Jupiter are the hardest cubes.
Uranus and Saturn are easier if you had understand how it works.

But a usefull sequence for you is the Neptune as next cube.
Neptune is the interesting way to solve a cube from one corner to the diagonal corner.
Very interesting. You lern sequences to orientate and permute corners. This sequences are usefull for all other cubes.
I am considering to order the two variants Bermuda fisher.

Cheers,
Andrea

Hi Konrad & Andrea,

I solved them in the order Mercury (cubic), Venus (cubic), Earth, Mars, Neptune, Jupiter, Uranus, Saturn. I was happy with the order that I solved them in. But in hindsight I see opportunities to build on methods more easily. People have also asked which ones are nice if you don't want the entire series.

I would say there are a few Key puzzles, but it depends if you want `the hardest` or the `least visually confusing` etc. so I will try to explain:
The Key puzzles would be:
Venus (cubic)
Earth
Mars
Uranus
(for a good `standard range` without as many `added difficulties`).
The others build on methods derived from those but have `visually confusing`attributes or `added difficulties`, but generally work off the format of those 3 or 4.

I would say that a good solving order would be:
Mercury, Mercury (Fisher's)
Venus (cubic)
Earth
Mars
Venus (Fisher's) This is a nice format and an interesting puzzle, but it is unfortunate to loose the original one.
Uranus Andrea is right to bring this up a bit in your solving order, it will affect your solving choices for the following puzzles.
Saturn
Neptune
Jupiter

If you like more visually confusing or harder puzzles, you might choose Earth, Venus (fisher's) and Neptune perhaps?
I hope that gives some people some options. This might be different if your methods are different though.

Cheers,
Burgo.

Hi All,

I solved my new mini Evil twins 3x3x3 tonight. I put it here because it is a lot like the Bermudas, maybe people who like them will also like this? It was harder than I thought :D .

Cheers,
Burgo.
