# The Roux "Example Solve" Game!

#### Renslay

##### Member
This thread is similar to The "Example Solve" Game! thread, but focusing only on Roux solves. We previously talked about this in the Roux Help and Discussion thread. That thread remains for detailed discussions and ideas, this thread is focusing on the solves and solutions. The main purpose is to help each other and to learn from the solves of others.

So, I give a scramble, and write down your own Roux solution. The solution can either be a "first try solution", which means you would do that during a regular speedsolve (or you can even do an actual speedsolve and reconstruct your solution); or you can do a Roux style FMC (e.g., searching for the best second block, experimenting with LSE around, and so on). But please note what type of solution you found.

Unlike in the Example Solve Game thread, please write down a new scramble only after a few days after the previous one; so many people can write down their solutions for the same scramble.

Note that this is not an FMC contest (although you can try ). There is no shame in a long solution, especially when you are a beginner. Moreover, the others can help you to cut down those long moves! Also, feel free to suggest other alternatives to others!

And most of all, have fun!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Scramble of the week:
(Yeah, yeah, I know it's sunday... Nevermind. )

B R2 F' R' D' R D F L U' F D2 B D2 B L2 U2 R2 L2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Okay, here is my first try solution, 45 STM. Block colors: red bottom, yellow left.

y z
F' r' F // 1x2x2 (3)
R U' r2 B // FB (4)
M' U M r' U' // 1x2x2 (5)
R U' M U r U' r' // SB (7)
U R2' U' R F R' U R2 U' R' F' R // CMLL (12)
U' M U2 M' U2 M' U M' U // EO + UL/UR in one step (9)
M U2 M' U2 M2 // M-perm (5)
alg.cubing.net

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

With a 10 minutes playing and searching, here is a 36 STM solution, with the same colors:

z2 x
B r b' // 1x2x2 (3)
U2 B' U B' // FB (4). U2 B2 is shorter, but with this I get a corner-edge pair for SB
U2 R U' F R' F' // 1x2x2 (6). Also pairing the last corner and edge
U2 R // SB (2)
U2 R2' U' R F R' U R2 U' R' F' r // CMLL (12). In the end, r = R M' (starting the EO)
U M // EO (2)
U M2 U' // UL/UR (3)
x M2 U2 M2 U2 // M-perm (4). Normally do M' U2 M2 U2 M', but this is shorter
alg.cubing.net

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Also another 35 STM solution, still the same colors:

z2 x
B r b' // 1x2x2 (3)
U2 B' U B' // FB (4)
U2 R U' r U // 1x2x2 (5)
r2 U r U2 r' U' M' // SB (7). M' = r R' (starting the CMLL)
U' R U' R' U2 R // CMLL with preserving EO (6)
U' M' U2 M U M2 U// UL/UR (7). U' U2 merged into U
M U2 M' // M-perm (3)

Here's my first try, maybe I'll play around more later:

Ill see how this goes and maybe make a ZZ Example solve thread

Also, weekly new scramble now? or daily when you have a lot of people posting solutions every day? or just "every once in a while", when it feels necessary, new scramble to be posted by whoever wants to?

my attempt:

x2 y'
U2 L' U' Lw2 U F' R U2 B //FB (9/9)
U' R2 U Rw U R' U' R' U2 M Rw' U' Rw //SB (13/22)
U' R U' L' U R' U L U L' U L //CMLL (12/34)
U' M' U M' U M U M U M2 U2 M2 U M U2 M //LSE (16/50)

I actually found a decent solution for once. I'm usually very inefficient, as my second block showed. I wouldn't have done this in a speedsolve and it was quite lucky, but I'll take it I think it would be 50 HTM?

Not sure how often should we deal with a new scramble. One week is definitely too much, I think 2-3 days is enough (or even change it daily). And anyone can post a scramble at any time; I just want to avoid the "new scramble after every single post" (like in the Example solve game thread), because I think it is better if you see numerous solutions to the same scramble.

BTW, Renslay/GuRoux/anyone else, is there a better L6E than this? I'm starting to wonder how I can improve that portion.

That seems normal. LSE is usually between 12 and 18 moves for speedsolves with an average around 15 moves, at least for me.

One note:
Most of the time I personally like to orient the center right after the second block by choosing R or Rw. All my CMLL algorithms preserves the centers.
If I did not orient the centers somhow, then I finish my CMLL with an Rw move instead of R (vice versa). For example, in your solution, you ended up the CMLL with R, and you had to start LSE with an M move. Instead, you could end up the CMLL with an Rw in this case.

As for that particular LSE, I would do this:

Scramble: the inverse of M U M' U M U' M' U' M' U2 M U2 M U' M2 U2.

My first try speedsolution:
M' U M' U' M U M' U M' / U M' U2 M' U M2 U' / M2 (17)
Seems quite average.

Instead of M', you can also orient your edges without orienting the centers first. So in the beginning only UR and DF edges are misoriented, and a solution could be:
U' M' U M U M' U' M' / U2 M2 U / M2 U2 M (14)

I don't think there are much better solutions without making some serious optimization effort.
For example, using the Misoriented Centers Table, you get
U' M' U M U M' U' M' / U2 M2 U / M2 U2 M (14)
which is the exact solution as above!

Or using Josef Jelinek's 2.5 look LSE method:
U' M' U' M U' M' U M' / M2 U' M' U2 M U2 M' (15)
or:
U' M' U' M U' M' U M' / M2 U' F2 M F2 M2 (14)

So, overall, your solution seems pretty good; and instead of the movements you have to focus on transitions and lookahead. You have to see your UL/UR case while you are in the middle of the edge orientation.

Edit: your solution is 16 moves, not 15, just saying. But that is negligible.

You should work on your FB: e.g instead of building your pair like R U Rw' U2 M' L' U L (FB in first try) you better do this: F U' R2 F

LSE looks OK for me, in your first try i would do this: U' M U' M' U M2 U M2 U' M U2 M'

You need to work more in the blocks, especially on your first block. For example, you use M' L' U L in the end. Why not R' F?
For the first block with the same colors, I would do:
x2 z'
B' u' R b' / R' U M R B' (9)
The second block is not bad, however... R M R'? Get rid of that.

And here is a shorter LSE with 10 moves:
U' M' // EO with misoriented centers (2)
U M2 U // UL/UR (3)
M' U2 M' U2 M // M-perm (5)

Second try:
//Inspection
R2 Uw M' U2 L' U L B Rw' U2 L U' L' // FB (13)
U' R' U2 R Rw U' Rw U' R U' R' M' U2 M' Rw' U' Rw U Rw' U' Rw // SB (21)

60 STM

Yes, your blocks seems your weakest point (no wonder, those are the hardest parts of Roux).
Again, you are using L' U L instead of r' F, and L U' L' instead of r B'.
A better first block with the same colors:
y
L2 D U2 B2 / F2 R2 U' M r' F (10)
or:
x y
B2 D M' r b' / U r U2 M' B' (10)

For the second block in your case, I would do:
M R U' R' U' M' U' R U / R U M U2 r U R' (16)
or:
M U2 R2 U' r U R U2 / R2 U' R' U' R (13)

Try to minimize your number of moves. First block should always be less than 12 (less than 10 later), second block should always be less than 20 (less than 17 later).

And your LSE is not working.
As for LSE, I would do:
U M' U M U M' U M / U' M' U2 M U M2 U / M' U2 M' U2 M2 (20)
Yeah... long. It seems the worst case scenario for me; each part so long, no shortcuts...
Using misoriented centers it becomes a bit better:
M U' M U M' / U2 M U2 M' U' / M' U2 M U2 M (15)

Thanks a lot for all the help. Blocks are definitely where I am weakest (although everything else could use some work). I'm still working on the whole blockbuilding mindset and getting used to being able to use the whole cube.

#### Renslay

Yeah, that's better.

Edit: I just found this one.
U M U M U M / U M2 U' / E2 M' E2 (12)
where U' E2 could be U Uw2 (maybe more comfortable).

Your FB had some weird moves. It should have been: D' B' D2 U' R' F (6)

The rest should be pretty simple.

Fixed that for you.

On first look your LSE seemed long. But then I tried what would I do (as a speedsolve solution), and ended up with a 19 move solution... So, never mind. I hate worse case scenarios!

I got a 16 move solution for his solve (in my first try), so i also thought his 20 will be OK for a speedsolve
