Those are the different cases. Some people use letters, I prefer terms, because they are easier to remember:

Headlights
Blinkers
Double Headlights
Bowtie
Chameleon
Sune
AntiSune

is how I remember them.





That site will be really confusing right now, because it has all the 43 cases. You only need to learn 9 algorithms right now.

Let me explain the difference between 2 Look and 1 Look:

There's eight different ways the corners can be oriented (meaning the ways they are twisted). Those are how I described above, along with an already solved one (where they are already all facing up).

There's six different ways the corners can be permuted (meaning where they are located in relation to each other). These are various swaps, swap top two corners, bottom two corners, left two corners, right two corners, diagonal swap, and finally already permuted correctly.

So, in order to do all of the corners with one algorithm (one look). You need an algorithm for each permutation case (6) within each orientation (8), so 48 algorithms. There are some that reflect symmetrically, which reduces the 48 down to 43.

However, we can do what's called "Two Look" CMLL. This means you will use one algorithm for orientation (twisting) and one algorithm for permuting (swapping). This means you only need to learn one alg for each of the 8 orientation cases (minus one, because it's already solved), and one alg for each of the 6 permutation cases (minus one, because it's already solved). However, for permutation, symmetry means you only need to learn two algorithms.

This reduces the amount of algorithms you need to learn from 43 down to 9. This is nice, but it also means you will have to apply two algorithms for each solve rather than one. Everyone learns 2-look CMLL first, and then expand into 1-Look when they are ready.

Ahh, thanks for explaining. So where can I get like some printable sheet with the tutorial on Roux and all the algorithms with images?
 
Three roux beginner questions.

I just started to learn roux to try it out, because I was a bit frustrated at CFOP that I have a very hard time learning full PLL (just for background I'm sub-30 at CFOP).
I have three questions:

1)
When I do the bad edges,I all cycle them until I get the arrow as on step 4a here.
 Is it better to do it that way or learn it intuitive. If intuitive can someone give me a hint on how to do it that way,I can only find it's intuitive or a list of algorithms. How to figure intuitive out,or is it just trial and error and cube knowledge?

2)
I always combine the first and second 1x2x3 blocks. Why is it that you first should do the first and after finishing do the second.

3)
I read that roux is rotationless ,but inserting a pair (1x2x2) takes sometimes rotations,how can you avoid this (I don't want to learn it whit bad habits).

So,that's almost a list of questions *sorry*.

Thanks for taking the time to help this beginner in roux,with answering my questions.

1) This step should be quite intuitive, and with time, you'll easily memorize each case, but you can look at some good algorithms for cycling here.

2) You should be attempting to memorize as much of your first block as you can during inspection. The idea of the first block is to assemble it with very few move restrictions to allow for very low movecounts. If you start working on the right side, you begin to limit your moves, which raises your movecount. So basically, better utilization of inspection and better movecount if you do the left block first (generally).

3) I need an example to see where you would need to rotate, because I never need.

Thanks for your help.

I did a few slow solves and found that I could do it rotationless.
It only feels awkward,so I think that's why I thought it was impossible (for example setup:B'U'B).

yeah, the B moves are weird.. Honestly, for first block, x rotations are fine if they help with F or B moves. y rotations should be very rare though.

For 3), use M/r moves to switch the orientation of the edge to avoid rotations. EG r U R'/r' to insert a pair.

Thanks for your answer.
I now found a better solution for the my setup (B' U' B) that I used as example.
U l U l'

Never thought of that before your hint!

I wouldn't use that, I'd just use U B (assuming this is the first block - do you make your first block on the right?). You don't need to use wide turn for your first block, I would aim to just keep the move count as low as possible with rotations or B moves in this case. However the opposite (r' U' r) is a good insert for the 2nd block on the right.

I do think there's a lot of good reasons to use wide r/r' on the first block. I never use l/l' though.

That would be the case for a second block though.
I make my second block on the left (first on the right).
I know realise,I do this opposite than the "normal" roux solver,maybe I should change that habbit.

Umm... unless you're left-handed, you should do the left block first, because your moves should be restricted to URM on the second block, meaning a lot of right hand turning.

I'm right handed,so I'll switch to a first block on the left.

I tried it and it feels better with al the R instead of L turns.
I have no clue why I previously started with R.

Thanks again guys!

No problem. If I were you, I'd check out some walkthrough solves. I have a few on my youtube page (link under my user name).
