    I’m a CFOP man but Roux interests me, I just can’t seem to wrap my head around the last algs yet.

    I guess I’m a speed solver, just a slow one. I’m nearly 40 and just wanted something to occupy my mind rather than Reddit (social media in general) and it’s certainly done that. Currently I’m working through learning OLL, then it’s PLL which is apparently easier.

    I like being able to stand at a bar 6 beers in and solve a cube in a minute or two with one eye shut, and I like that I had no clue how to do this 3 months ago and now I’m faster than the majority of people at it

      Huh, I’ve always seen people recommend learning PLL before OLL. Hope that’s going well for you, anyway. I’d recommend you learn algs that work well for you rather than whatever your source suggests (check some algs out over on algdb.net).

      Also, you may want to check out the Speedsolving Forums. I’ve used them and here to supplement my lack of visiting the cubing subreddit.

        Thanks for the algdb.net link, looks like a good site. I’m using https://www.speedcubedb.com/a/3x3/OLL atm because I like that it tells you how to set the alg up too, but I’ve bookmarked your link.

        There’s this https://www.reddit.com/r/Cubers/comments/tygask/learn_oll_the_easy_way/?share_id=d53oqI0G9XwOvG9JN9kXi&utm_content=1&utm_medium=android_app&utm_name=androidcss&utm_source=share&utm_term=1&rdt=32907

        Which is a great little resource, just a pity it’s on Reddit.

        OLL seemed to make more sense to me because I already know some of them, and the rest seem to be variations of them, so I just need to remember that THIS case does this, but if it looks like THAT then I vary it like THIS.

        PLL just makes my brain hurt, hopefully OLL will help with that.

            Hey thanks that’s great, I’ve just gone and saved that to my home screen on my phone.

            Also it may not be as active in here but my original intention was to stir up some activity and it seems to have worked. I’ve talked more about Cubing this week than ever before and that is good enough for me.

          I’m using https://www.speedcubedb.com/a/3x3/OLL atm

          I didn’t know about this site and, just from skimming it a bit, I’m impressed. I’ve just come back to cubing after a 3-year long pause and didn’t catch up with the times, so thanks for the link, I’ve bookmarked it also.

          Which is a great little resource, just a pity it’s on Reddit.

          Yeah, sucks to be a cuber and wanting to be away from Reddit, because the r/cubers sub was actually one of my favorites.

          PLL just makes my brain hurt, hopefully OLL will help with that.

          It definitely will. Some PLLs are just combinations of shorter OLLs (take the T perm, which is a sequence of a T OLL and a fish-shape OLL), so it’ll definitely help you out. Also, the fact that there’re way fewer algs in the PLL set will make it a breeze (hopefully) after you grind through OLL, so maybe that’ll help out your motivation. Still, I think it’s a bit odd to learn OLL first, but it seems fine and even good now that I think about it.

            Yeah the speedcube db is great because it’s all in sections so you can pick say Fish Shapes and just concentrate on them.

            As for PLL or OLL first debate, I’m already doing 2 look so the idea is to get down slowly to 1 look. I keep going back to Guitar analogies and it doesn’t really matter the order on Guitar that you learn once you have a solid foundation. I really am treating Cubing the same way.

            When I get bored of OLL I’ll go to PLL and switch back again. It’s a way of staving off the boredom while teaching my muscle memory.

            I’m already at a point where I’m getting a little frustrated at forgetting some OLLs so it won’t be long. Thanks to you I’m learning T perm first

      I guess I’m a speed solver, just a slow one. I’m nearly 40 and just wanted something to occupy my mind rather than Reddit (social media in general) and it’s certainly done that. Currently I’m working through learning OLL, then it’s PLL which is apparently easier.

      In my opinion, if you time yourself, you’re a speedsolver. I’m older than you (43), but I know that I won’t reach sub-15 since I can train “properly”. I’ll be happy to be sub-20 !

      Learning 78 algs (even though I knew more than half of the PLL) was definitively a deal-breaker for me. Even with CMLL I struggle to reco the pattern and then reco the alg associated… I know that I lack practice, but I’m glad other methods exist  ! (I looked at Petrus and Heise before Roux).

      I’m a CFOP man but Roux interests me, I just can’t seem to wrap my head around the last algs yet.

      The LSE stage? At first, you can go without algs. Here how I process it:

      After CMLL, the last step is divided into 3 parts:

      • 4a: edge orientation (EO)
      • 4b: finish L and R sides (if done with EO: EOLR, but don’t learn that yet. I still don’t know it :þ)
      • 4c: permut M edges

      4a: If you take the time to analyse EO, you’ll see it’s really simple. Let’s say that top/bottom is yellow and white:

      • The goal is to have only yellow/white on top and yellow/white on bottom.
      • in order to achieve that, you “reduce” all your cases to the “arrow case”.

      If you don’t know yet, arrow case is 3 non-white/yellow on top, and 1 non-white/yellow on bottom. Once you have an arrow, you do M’U*M*, with *=’ or *=nothing (or MU*M* depending on the arrow facing you or not)

      Except for the 6 flipped-edges, there are 3 cases that are not solved/arrow cases:

      • 2 adjacent flipped on top, 2 on bottom : M2 and you have the arrow example
      • 4 flipped with 0 adjacent (4 on top, or 2 on top opposite, and 2 on bottom) : the goal is to swap UF and DF (or UB and DB): M’ U2 M can achieve that (in fact, I think that M* U2 M* are ok) example (4 on top), ex2(2 on top, 2 on bottom)
      • only 2 flipped : M* U* M* will do the trick (they can’t be on the same face). I put the one on the M slice on D with M or M’, then I put the one on r/L on top of the other one with u/U’ and I bring the first one on top again with M/M’ :

      ex1 both on top

      ex2, symmetrical to ex1

      ex3 both on top again

      ex4 1top, 1 bottom

      ex5 1 top, 1 bottom, diag case

      ex6 1 top, 1 bottom, same face

      ex7 1 top, 1 bottom, same face2

      ex8 2 bottom

      You can see that in a lot of cases, the last M can be M’. But I like to keep it simple ;)

      For the 6 flipped edges, either you learn an alg, or you M*U*M* to reduce to only 2 flipped: example

      See also the flow chart in https://rouxl.es/lse.html


      4b: in this step, your U and D faces should have yellow/white stickers only.

      The goal is to finish the left and right sides (that is, put UL and UR). In order to do that, the easiest way, is to put UL/UL both in D, adjust the U face, do M2, and put U correctly.

      In all other case, we first bring them diagonally of each other on the M slice.

      • if one on U, one on D, AUF
      • if they are on U, but adjacent, M2 to bring one on U, one on D. Then, AUF.

      And then M* U2 M* to bring them both on D:

      ex1

      ex2

      ex3

      And then you finish with AUF,M2,AUF

      Sometimes, you can merge the two steps:

      ex4

      That can happen when one of UL/UR are between L/R corners. I’ll let you experiment with it.


      4c: L and R are solved now. You just have to permut M edges now.

      There is really only 3 cases: bars, dots, and cycles.

      • for bars, it’s just U2 M2 U2 (with M* setup)
      • for dots, E2 M E2 M’, or (U2 M’ U2 M2 )2, or (U2 M2 U2 M’)2, or any other alg
      • for 3 cycles, on the M slice, you will have 4 “blocks”: 1x2, 1x2, 2x2 and 1x1:

      ex 2x2 is yellow-blue, 1x2 are green-white, and yellow-green, and then 1x1 is white-blue.

      You’ll have to do U2 with the 1x1 without breaking the 2x2.

      In the example, if you do U2, you’ll break the blue line of the 2x2, so you first have to do M

      Doing so, you will have a 1x3 line (here white line) and a 2x3 block (here with yellow line).

      Then you bring the 1x3 on top, U2 ( and sometimes M*)

      Hope it helps

        This is the first comment I’ve bookmarked on Lemmy. There’s a lot here, thanks. I’ll defo be coming back to it
