Roux Method Lse - Last six edges - Complete guide - Tutorial
Full Tutorial on the LSE/L6E step of the Roux method. Last Six Edges has 3 mini steps: 4a is solving the edge orientation (EO) , 4b is solving the UL/UR edges, commonly called the LR edges and lastly 4c is solving the rest on the middle slice. For this, we have BU Recognition or you can solve it intuitively too. This is aimed towards beginners and contains intermediate and advanced stuff also. ► Time Stamps Introduction: 0:10 Edge Orientation EO Cases: 1:36 UL/UR Solve LR Cases: 12:36 4C cases: 17:36 AUF Prediction: 24:48 ► Roux Resources LSE Edge Orientation EO: tinyurl.com/eokian Algs for Blocks: tinyurl.com/f2balgs CMLL: tinyurl.com/cmllkian Waffo: wafflelikescubes.webs.com Roux Playlist: ****** Good video on First Block: ****** Intermediate LSE Guide: ****** BU Recognition: ****** GuRoux 6 Flip: ****** ➞Make sure to follow me on Facebook and Instagram and Subscribe on Youtube :) ♞Instagram: ****** ♞Facebook: ****** ♞Twitter: ****** ♞Skype: criticalcubing INTRO Creator/Designer -- Official™ | OffTM4 Link : ****** Music Used: Hinkik - Outbreaker ****** Instrumental produced by Chuki ****** Thank You All!

Hello guys its me CriticalCubing and today I am making an in-depth video on the LSE step of Roux method
LSE is the last step of Roux method, its the 4th step in which you solve the last six remaining edges, hence LSE
4 edges are on the top, and 2 on bottom, hence 6 edges. LSE can be broken down into 3 mini steps
First step, is 4a and you solve Edge Orientation
Here you make all the sticker on top and bottom, either white or yellow
In this case, I have green and red so I switch them up and make all stickers white/yellow
Next step is solving UL/UR edges which is solving the right side of the cube, and the left side
In this step, you solve the edge that comes in here and the edge that comes in here
For solving this step, you keep both the edge in bottom
and then you just put them on the top like this
and then you solve this side and this side
The last step is called 4c in which only the middle slice is left to be solved
and you solve the middle slice by doing one alg like this
Those are the 3 steps of LSE
4a is solving edge orientation EO. 4b is solving UL/UR edges and 4c is solving the rest
Now we are going to get indepth into these steps
First step of LSE is called edge orientation and in this step you get all the edges to be either white or yellow
and in this step, we are introduced to the concept of bad edges and good edges. Good edges are edges which already have white/yellow on top like this one
and bad edges are those edges that do not have white/yellow on top. Red is bad edge, green is bad edge, blue is bad and this is good edge
And the most important case of EO is called Arrow case. In arrow case you have 3 bad edges on top
and one bad edge will be in the bottom
Now if you have yellow or white facing towards you in the bottom piece, that means its a bad edge
otherwise if you have any other sticker like green/red that means, its a good edge
This is the arrow case, 3 on top and one on bottom and for solving this when the edge is in the front
you do M' and then you do U or U' and you do M' once more
and this is the next arrow case and this is from the back and one important thing to remember when recognizing bad edges and good edges
is that bad edges will always come in pairs, so there will never be odd number like 1/3/5 and they will always be even 2/4/6
For example, I see 3 bad edges on top and this is not a bad edge. Because bad edges always come in pairs
the last bad edge is at the back as 3+1 is even no and bad edges always come in pairs
and for solving the arrow case with edge at the back, you do M U or U' and then M'
Now we are going to go over each of the EO cases and first I'll show you the beginner cases and then more intermediate ones
First we are going to start with 2 flips and this is the first case and in this case you have 1 in here
and one in here, and this can be either vertical like this or horizontal like this
and for solving this 2 flip case, you do M' U' M
for getting the arrow and you can solve the arrow by doing M' U' M' or M move
Now the same 2 flip case can be in the bottom and for solving the case when its in the bottom, you do this
M' U' M' which gives us the arrow case and then you can solve the arrow
This is the next 2 flip case and you have both of the edges adjacent to each other
and when you have these two in this position, at the back and the right, you do this
M' U' M' which brings us the arrow case and then you just solve the arrow case
this is the same 2 flip case as before but now you have the edges in right and front
and you can always do U' and solve from here, but if you want to be even more efficient, you can solve it from here too
but doing M U M which brings us arrow case and then you solve the arrow case
this is the same 2 flip case from U2 angle and for solving this you do M U' M'
which gives you arrow from back and then you solve arrow case
and this is the same case from U' angle and for solving this you do M' U M
which gives you arrow case from front, and you solve arrow
do remember one thing, arrow cases from front start with M' move and then you can do U' or U move
and then you can either do M or M'. Only the first M' move matters, after that you can do U, U', M, M' and the EO will still be solved
same goes for the arrow cases from the back. Only the starting M move matters
then you can do U, U', M', M and the EO will still be solved
this is the last 2 flip case and you have 2 edges like this
one on the top and one on the bottom, and when you have the case like diagonally opposite from each other, you do this
M U' M which gives you arrow and then you solve the arrow case
and you can get the case like this and this is just the mirror case. Instead of using M moves, you use M' moves
For solving this case, you do M' U' M' which gives arrow case and then you solve arrow
Now sometimes you may get cases like this where you have edge on the side, instead of being on the top
and in these type of cases, instead of doing U and solving it, you can solve it from here too saving 1 move
the thing that you have to do is insert the edge, where the good edge is
In this case, I have the bad edge at the back, so I insert the edge in here with M' U M
and that will give me the arrow case from the back so I can just solve arrow cased
and when you get the case like this with the bad edge in front, you insert the edge at the back with M U M'
and that will give you the arrow case from front and you can solve the arrow case
Now comes the 4 flip case and in this case, you have 2 bad edges on the top, and 2 on the bottom
and for solving this case, you keep the bad edges on the top in horizontal line and these will be vertical
and for solving this you do M' U2 M'
That will give you the arrow case and you can solve the arrow case
This is the next 4 flip case and in this case you have all the 4 edges on top like this
and for solving this case you do M' U2 M' and then you solve the arrow case
This is the last 4 flip case and here you have 2 bad edges on the top and they are adjacent
and 2 will be at the bottom and for solving this, you keep the bad edges anywhere you want
Keep the bad edges anywhere and do M2 and then solve arrow case
for example, I can keep this in here and do M2 and I get the arrow case
and then I can just solve arrow case for solving this EO case
