    I can't tell from the images on:
    http://grrroux.free.fr/method/Step_4.html

    if the edge you can't see matters for step 4a.

    I also find this step to be tedious and frustrating most of the time, does anyone have any tips?

    Thanks :D

    roux present diferents cases and simple algs to solve it.

    The method is iterative : when you appli an alg, you just obtain a different case presented by roux.

    The solution is always very simple.

    ok, you say it is, what helped you get good at it?

    Well, I just spent 30 minutes to find out how to orient all the cases, and then it's just a matter of practice.

    Again, sorry for a bump, but the question still remains about the webpage, does the "hidden" edge (back down edge) in the diagrams for the orientation cases matter?

    yes.
    But if you know the orientation of every edge but that one you will know what orientation it is..

    really? how? and does it change the algorithm used in the case if the back one is right or wrong?

    Well you will always have an even number of edges oriented correctly. thus if you see an even number of oriented edges you know the one in the back is mis-oriented and if you see an odd number of oriented edges then you know the one in the back is good.

    Ok, but how does having the one in the back wrong or right change what you do to "fix" them?

    Just match your cube to the diagram and perform the moves. Remember that it is an iterative process. As Lofty said, there will always be an even number of unoriented and oriented edges of any cube. So if three of the five edges you can easily see are unoriented, then the BD edge is unoriented. This shouldn't matter to you now since you are just matching to the diagrams, but you can easily tell if you are done if the visible five edges are oriented.

    thank you for being patient with this, I feel my attempts at roux really have helped my CFOP style solve, and now I feel my advancements at CFOP will be helping me with roux. I'm thinking of going to roux for my 3x3x3 and CFOP after reduction for my larger cubes.

    I had a bit of trouble understanding this step but then I realised that

    MU'M swaps two pairs of edges in such a way that it reverses the orientation.

    Drawing a diagram to see which step leads to which step helped too.

    Yes, I can see how that would help a lot... I could then string together the simple moves into a longer move for each starting case, and have a better idea what to "look" for after finishing.

    Help with roux method

    I'm new to cubing. I started about a month ago. I first discovered Dan Brown's vid on Youtube, which helped me get my first solve. I soon learned that that was NOT the way to go so I started intuitive F2L. Then 2-look OLL and 2-look PLL. My best single is 1.10.xx and my best average is around 1.15.xx. Anyway the full oll and pll seemed a little daunting so I thought I'd give petrus and roux a try. I really like roux and understand all the steps except for the orientation of the six edges.

    Could anyone help me/give some advice? I saw that in the thread further down by Smartyy, ooveehoo said that was his favorite step (unless it was ironic :p).

    All help is appreciated

    Welcome to the forum.
    The orienting edges step seems pretty self explanatory to me what dont you get?
    Can you identify which ones are not oriented correctly? If so then you simply recognize the case and apply one of the simple algs.

    Thanks, Yeah I can easily tell if an edge is oriented correctly or not but I have a hard time recognizing which case I have so I can apply an algorithm. And if I understood correctly, once I find the right algorithm to apply, will I have to apply it several times to work through a sequence before getting the final result?

    Once you apply the algorithm you will have either all your edges oriented or you will have a different case (or the same one) so dont just keep doing the same one over and over.

    Ok, thanks. I finally got it. It was pretty dumb actually. Anyway, my times shot way up but that was to be expected.

    best time so far : 2.15.77 but I guess that's still pretty good for a beginner.
