    Oooh, sorry I didn't know you were on a void cube, and also I thought you meant the edges were seperately flipped, so the alg I gave you won't work.

    Since I haven't really solved on the void cube I'm not 100% sure what you should do to fix it, I think it has something to do with the colour scheme, so made sure the sides you build on are all correctly matching to a normal cube
     
  2. You have Void Cube parity, which occurs when the centers have not been properly placed while solving the rest of the cube.
    This thread has some algorithms for solving those cases.

    Also, a better flipping alg (I think) is: Rw U R' U' Rw' U2 R U R U' R2 U2 R

    Thank you anyway! I now have that Alg. Memorized in cases where the need it!

    My average is currently just below 20 seconds. I currently use cross on top, know some f2l algorithms, know about 40 OLL algorithms, and know all the PLL algorithms except the Gperms. My cross takes around 3 seconds, I can finish f2l in around 10 seconds, OLL in around 3 seconds and same with PLL. What should be my next area of focus? Thanks

    I'm currently learning 2 look pll and have run into a bit of a problem. I thought that the idea of 2 look pll was that you are guaranteed to solve the last layer permutation in two algorithms / looks. For the case with the headlights this is always the case. But when there are no headlights and you have to do a Yperm or Eperm I sometimes then get the headlight case which means I then do the three corner rotation which then presents one of the last four edge rotations. This means that actually it's 3 algorithms.. am I doing something wrong?

    The case with no headlights involves swapping two corners diagonally, which the Y-perm should do from every angle. That automatically will give you an edge permutation, so maybe you're doing your diag-swap algorithm incorrectly?

    In addition to what DGCubes said, you might also be recognising the case wrong; maybe you didn't notice headlights on the left or back faces? In that case, applying a diagonal swap would still leave you with an adjacent-swap case, which would explain why you sometimes need 3 looks.

    I was mainly using this Eperm if I didn't see headlights... Should this work...



    Thanks for your help!

    There's a stickied thread called how to be sub 20. Also, Cyoubix has a YouTube video called "why you're not sub 20 with the Fridrich Method".

    I suggest you search for more algs for these cases (different people like different algs), but this is Badmephisto's sheet of cases for 2-look OLL.
    You might as well learn full OLL, since you probably will eventually, but if you really don't care about being competitive, then it's not really necessary.

    Have you learned full PLL yet? If not you might want to check out some other methods which don't use full PLL or OLL

    All but 3 OLLs have a 1/54 chance of occurring. You should learn all but these cases.

    Isn't it all but 7?
    (including skip. All but 6 excluding skip)

    I was being facetious. Probably.

    Actually, the spread is like this:
    1/216: 2
    1/108: 5
    1/54: 51

    I'm currently doing cross on bottom, intuitive F2L, 4LLL. My solves are around 1:10 on average over the last 50.

    My F2L can take around 40-45 seconds which I think is my biggest area of improvement. I have been slowing it down to practice lookahead since it takes me a little bit to recognize pairs. I'm also *always* rotating the cube to do the inserts.

    My question is should I immediately start learning to do my inserts from all sides? Obviously this is going to slow me down at first but I am trying to figure out if I should add learning this on top of pair recognition or practice 1 at a time.
