Solve error.

I'm trying to solve my square-2. I thought I'd got all the corners paired up correctly (after accidentally pairing up orange / orange etc :oops: ), but it seems I was one pair out. Is there an alg to fix this without having to scramble it completely? I can fix the edges, but it's the corners I'm annoyed at.

I'm indicating the two swapped corners here:

Anyone help?

you'll find many algorithms to solve the square 1

http://www.jaapsch.net/puzzles/square1.htm

and you can use them for the SQ2.

a great part to solve it is without algorithm learned by heart, only intuition.
I only need 3 of them for both of those cubes.

method 2 phase 1
e.
1. Swap DFR-DBR: (1,0)/(0,-3)/(3,0)/(-3,0)/(-3,3)/(-3,0)/(2,0)
method 2 phase 2.
9. Swap DR-UR, UF-UB (1,0)/(0,-3)/(-1,-4)/(1,1)/(0,3)/(0,3)/(-1,0)
method 2 phase 3. b.
5. Swap UF-UR (0,3)/(-3,0)/(0,3)/(0,-3)/(0,3)/(2,0)/(0,2)/(-2,0)/(4,0)/(0,-2)/(0,2)/(-1,4)/(0,-3)/


with the second one you can swap a piece on a bad place from top to bottom, then turn top to put good place right and then swap piece back to the right place on top.

I've managed to solve the Square-2 entirely with algorithms I also use for Rubik's UFO and the cheese. They may be a little easier to remember.

Just repair the corners, whilst making sure you don't scramble the rest. I got two of them yesterday, and I've solved them about six times or so. Just work it out like that, it makes it more fun!

The question should be: Is there a method for the square-2, without passing by the square-1?

That would be great for solving!!

I've fixed the edges, but I'm not sure what WilliamF means with his method.

What I'm hoping for is a simple alg that will switch those pieces (with notes on which way to hold the cube to use the alg - I don't want to end up switching the wrong pair :oops: ).


Cheers.

Off course, it should be, just need someone to seek.

Maybe there is the exact algo for your case but what I explain is my method for solving this cube : few algo to solve all possibilities.

Image
Swap DR-UR, UF-UB means : edge Down-Right swap with edge Up-Right and edge Up-Front swap with edge Up-Bottom
the algo is (1,0)/(0,-3)/(-1,-4)/(1,1)/(0,3)/(0,3)/(-1,0)
for notation, see http://www.jaapsch.net/puzzles/square1.htm#s2

What I want to say is that when first face is done ( for you down face) you can use one piece in this face ( down) as pivot. You swap a piece from Up-face to down-face , then you turn up-face in order to put the right place for the piece you swapped down.
Then with the same algo, you put this piece up.

Maybe I can add pics if you need.

here you can see that I swap any piece (corner or edge) from Down face to Up face then turn Down face and then swap back this piece in right place.

I didn't use your exact method, but it did make me realise that I could swap half corners using my normal edge swapper alg:

Swap UR with UB and Swap DR with DB alg - (0,2) / (0,-3) / (1,1) / (-1,2)

I repositioned one corner piece in the DR slot and swapped the edge with the back. This left me with 3 to swap. I then swapped the same corner piece (now 90 degrees closer to the place I wanted it) with the other one where I wanted it.

This left me with 2 corners to swap 90 degrees apart. I repeated and it put them right. Just left me with a standard square-1 parity case, which was no problem.

Thanks.

Obviously, there are many possibilities to solve the SQ 2.
Another method is viewing it as a Masterball variant.
Jaap has described an easy method for "any masterball" on his webpage.

I believe, if you have neither seen the Square-1 or the SQ-2 before, the SQ-2 is the much easier puzzle, because it is very regular.
Any opinions?

try treating the corner halves like edges
you should be able to use an edge switching algorithm to solve that

The only problem with that is that you have to be able to recognise the pieces and their permutations, and that's quite a skill. What you can do however, is quite literally put the two halves next to each other of the corner, and then solve it like a Square-1.

My Square-2 solve: http://www.youtube.com/watch?v=8cKsDr1JfbQ

You can sort of see my method in it.

i just got mine yesterday and i found it to be a really easy solve
yes it would be easier if there was a square-2 method but it's just as easy to pair up the corners (FIRST)
then solve it like a normal square-1
that's what i will continue to do until someone comes out with a method (because im LAZY)
