    I didn't disassemble my 3by3 or anything but now I'm getting a wrong OLL again and again even when F2L is in correct order. Currently dealing with the picture attached. What's going on? IMG_20180701_222309-compressed.jpg

    If you have that and the first two layers are solved, it most likely means you twisted a corner somehow. You'll have to twist it back. It's not possible for only one corner to be misoriented if the first two layers are solved.

    With some cubes it's not that hard to just twist a corner in place. See if you can do that so that you have an OLL that you recognize.

    Yeah, I've had this before when I've unknowingly twisted a corner. Twist it back clockwise and do sexy,sledge,sexy,sledge

    @ZF slow I don't really know what sexy, sledge is. Can you please post the algorithm?

    Here
    Twist a corner to get a normal OLL.

    @Duncan Bannon Ok thanks. But how do I do this? What is the algorithm?

    No algorithm to twist a corner. Just use your fingers to grab the corner and twist. The corner will rotate 1/3 of the way around. I would twist the bottom left corner (in the picture) and twist it so that the yellow faces you. Then solve like normal.

    @Duncan Bannon Well twisted it, then got an Aa perm. Now solved. Thanks everyone!

  9. That would be a terrible algorithm, but what he meant was:
    Sexy move=R U R' U'
    Sledgehammer=R' F R F'
    Also,
    Inverse Sexy=U R U' R'
    Inverse Sledgehammer (Hedgeslammer)=F R' F' R
    so
    R U R' U' R' F R F' R U R' U' R' F R F'

    The algorithm that I would use would be twisting the top right corner clockwise and then doing
    M' [sexy] M [inverse sexy]=Rw U R' U' M U R U' R'

    @GenTheThief Oh okay, got it now. That seems long, manual seems much easier. Thanks!

    Just for reference, that algorithm was referring to the OLL case you'd get after twisting a corner. It's impossible to twist a single corner with an algorithm; it happens because a corner was accidentally twisted at some point earlier in the solve, so it needs to be twisted back manually (mathematically, it doesn't matter which corner you twist, as long as you twist it in the opposite direction of the initial twist). This does not mean you should twist corners in other situations, and you'll only ever need to twist a single one (competitors have gotten in trouble for twisting more than one corner per solve in competitions, and for twisting corners when their cube was solvable without it).

  12. Man, you seem so smart with the math-side of cubes :)

    Probably just a corner twist

    Shoutout to everyone who's had a non-cuber twist like 7 corners one way and 1 corner the other way, thinking they're making it SUPER IMPOSSIBLE

  15. My algorithm for that OLL is M' U M U2 M' U M.
