1. Introduction: Hi, my name is Byron. I've been solving
competitively for well over a decade and have been a Rubik's Cube instructor
for years with having successfully taught
over 400 students. This course will be
targeted at those which already have at least an
intermediate knowledge of the three-by-three Rubik's
cube and wish to learn how to lower their times by
reducing cube rotations. If this course is a good
suit for you or not, I highly encourage
you to take a look at the mini courses I offer
here on this platform. I'm sure you will find a
course that suits your needs. This course will be very
focused on the topics at hand with clearly explained
practical examples. We've got this whole
pair right here, so we can knock that out. Then we got this right here is afterall case which
is handled like this. Our u prime, R prime. This is just a case that seems like everyone has a
problem with faster. It looks like this. I look forward to hearing
from you at the end. And with that being
said, let's get started.
2. How to Look for Pieces: The first thing I would
cover when it comes to reducing cube
rotations is probably the biggest culprit
of many solvers is rotating the entire cube
to look for F20 pieces. If you don't initially find one, a lot of people
will usually rotate the cube until they
find something. This is fine given that you've exhausted every
other situation. But usually just doing a u or u prime in this instance
would save a key rotation. And you'll usually find the piece that
you're looking for. For instance, in this example, we have this green
and orange piece and we don't immediately know
where its edges located. A lot of people will rotate and realize that it's
actually in the top layer. When being in this
position from the get-go, all you had to do was
you and you would have noticed or even a u-prime and you would've
seen it as well. And you would've known that
that was the correct piece. This same thing when it
comes to not rotating is especially important when
it comes to old El and PLL. In either case, if you know all, all PLL or even to look, you should never be
rotating the cube in order to solve
any of those cases. For instance, here
this is an OH, ALL. Usually I see some people that if they see it
from this angle, they'll do a Y2 in order to
perform the algorithm for it. But if you happen to get it
in this angle or this angle, just do a U instead,
execute the algorithm. And then whenever you run
into some kind of Appeal, just execute that without
a key rotation unless it's required by the
algorithm itself.
3. What to do After Solving a Pair: This next issue is something
that I'm guilty of as well. So I'm sure I'm not the
only person out there. But once you solve an F2
L pair, for instance, this one right here, lot
of people will solve it. And because they're being
timed and they're in a rush, they'll immediately
rotate the cube to help scan and
look for pieces. And I know this
kind of touches on the same thing I was
talking about earlier, but this is especially important for those that try and do it. I would say habitually
or if not instinctively. So the second you solve a Perrier like jump and
you don't even take a second to look and see if you had to rotate the cube
in the first place. That will cut some time down. If you're able to solve a
pair and stop and look. Here's an example on how you
can exactly improve on that. Honestly, you want
to stop timing yourself for just a little
bit when it comes to working on this and
actually solve a little bit slower and make
yourself stop. So that way you can look
and make sure you have to turn a cube before
you actually do it. So for example, I have
this piece and this piece. If I insert that, stop right here,
don't move the cube. Just look around and see
what you can work with. We got this whole
pair right here, so we can knock that out. Then we got this right here. Now this requires a rotation unless you are talking about
more advanced algorithms. And then we're going to
look at this piece here. We ended up saving a lot of rotations out of habit and by slowing down and
taking a second, now, incorporating
that slower motion into your everyday solves
will come in time. You just have to become
more disciplined with it in practice and you can slowly migrate it into your
regular solving.
4. How to Handle the Hardest Case: Now I've brought this up a
number of times in my courses. And this is just a
case that it seems like everyone has a
problem with this. Usually I see people
solve by taking this out, like this, rotating the cube, pairing up and inserting. But believe it or not, there is a much better
way to go about it. For one, you can solve
it this way instead, and this will just
cut a rotation out. You can do a sledgehammer
which is a r prime, f our f prime. You're presented
with this F20 case, which is handled like this. Our u-prime R prime U
R u prime R prime u2. And then you insert that pair
with an r u prime, R prime. So doing the algorithm
a little bit faster, looks like this. In other way to handle this case is just strictly
algorithm based. And you would start by
doing a regroup here, and you would do a R2, U2, f R2. Use your ring finger
for a f prime. U2 prime, u r prime. I'm not too bad not doing this one a little bit
faster. It looks like this.
5. Rotationless Cross Solution: One case that trips
a lot of people up, including myself, is this one. Of course, assuming that you
solve the cross on bottom, I have a white cross that's
almost finished here. And we have one edge
that's flipped, but in the right
spot on the side. This is a case that is very
troublesome for a lot of people and there's a
very simple solution that I use in
almost every solve. You should be able
to easily cut out some cube rotations because
usually the way that I see people handled this
case is they will do an R2 rotate and then
they will bring it down like this or something
to that effect. But there's an easier solution that looks something like this. No key rotations required in
order to perform that move. All you have to do
is have the piece you need flipped on the
right side like this. And you're going to do re grip. You're gonna do a r prime, lowercase u, r prime,
lowercase u prime. And that will flip
that edge and keep the rest of your cross intact. This is a very versatile move because you can do it in
almost any cue position. Even if the pieces over here, if the pieces all the way back. If the pieces all
the way up top. Even if the piece is
all the way back here. You can simply mirror
the algorithm on the other side for when
you get that case, try incorporating this
trick into your solves. And I think you'll be
pleasantly surprised.
6. Update Your Algs: This is gonna be a
workload on some people, but you want to go through the algorithms that
you already know. Find the ones that
have rotations are the ones that you
really don't like that take you a long time and find new updated algorithms
that work better for you. For instance, this case, this old case that I have here, I used to do a rotation whenever I did this algorithm
and it was not fun, it wasn't easy, and it was definitely took some
time out of my solves. Now I don't have to worry about that rotation in the
middle of the algorithm. And I have a rotation list
option for this case, I'm able to keep my hands for
the most part and home grip and end in home grip and I
have no rotations to speak of. Definitely a good update. Go through all the
algorithms that you know and make sure
that you check the ones that you don't
like or that include rotations that could possibly be eliminated with
more updated outs.
7. Edge Position Dictates Rotation: I know some of you may be
asking how can you look at the case and know if you have to rotate or not immediately. Well, there's a very
easy trick to know, assuming that you're not using
advanced SQL algorithms. This is a really cool trick. So I got this handled where
the cross is already done. And we're just going to
kind of go through it. So for instance, let's
look at this case here. Looking at this case, let's bring them both
to the top layer. If you look at this edge piece, the edges green and a
side color is green, it doesn't have
to match exactly. I could have it over
here like this. If green is on the side with that color that it matches
is on one of the sides. There is no rotation
that needs to be had. For example, this is green. Green is on one of
my side colors, so I don't have to rotate. So I should be able to solve this case without a rotation. That's one. Let's look at another case.
Let's go with this one. And I believe this is
its pair back here. We'll get that out. Let's take a look. The side
color this time is red. Does read match. One of the side colors,
green on this side, blue on this side,
it does not match. So that's telling me I'm
going to have to rotate. You can rotate
anywhere you want. But seeing that
the slot is here, I want the slot to be in the
back as much as possible. Instead of rotating here and putting the slot in the front, I would rather rotate here, so that way it's in the back. So then I can solve this
case. Just like this. Without rotation. With rotation because it had to. Now that that's
solved in the back, I'm open to more options
here and I don't have slots, a whole bunch of slots filled up where I can't really
see the whole cube. So always try putting solved, solved slots in the back or
solve pairs in the back. So that way you have some
more open up options. Let's check, Let's take
a look at another one. So there's this
one and this one, psi colors blue, but
blue is in the back, so I'm going to have to rotate. So let's do it this way. If I rotate this way, I'll have the next
available slot right here. Let's pair these two up. Now we have this one. There is a special case for this one because if
you did take it out, this would not
match aside color. It would match the
front or the back, which means it
requires rotation. But for this purpose I'm
going to do it this way. So you know, it does
require a rotation. So just remember the
orientation of that edge. If it lines up
with a side color, matches aside color no
rotation is needed. But if it matches the
front or the back, you're going to have to rotate. Do this slowly at first
and over time it's going to become second nature
and you're going to notice it in an instant.
8. Wide "d" Moves: There are some people out
there that when they run into a case that
requires rotation, they heard from someone that you're not supposed to rotate. And so instead they tried doing
a wide D move or D prime. This is a horrible way to negate doing a cube rotation
because it requires you to adjust your grip to do
that movement and then readjust again so that way you can get back
into your Solve. Honestly in a key rotation in many cases is better than that. Or you can figure out different
ways to insert that case. For instance, we have this red and green case,
right in green here. We can pair them up like this. And usually they will regroup, move it, and that way they can insert it without
a cube rotation. The best way to go about
this particular case is to use your pinky to support
the middle layer and perform it this way by doing
a f prime, f L prime. It's completely rewritten. This doesn't require a cube
rotation and you're able to maintain home grip just
about the entire time. So we'll try incorporating
that instead. And if you're doing
any wide D moves, cut them out of every
single algorithm you have. I have not come across a single algorithm
where it's beneficial, but I could be wrong. There might be some where it
really works well for you. And if that's the
case and you test it side-by-side with a
different option. If it's better, it's better
and you should keep it. But for the most part, they have no real place when
it comes to solving. Under time.
9. Back Slots: There are many of you that
most likely already know this, but I'm sure that
there are some people out there that need to hear this when you're
doing your F2 L, I have the cross
already solved here. And this is the SQL case that I'm talking
about right now. Just as an example is this orange and blue case and the orange and
blue edges there. If you catch it from this angle and it's a simple
three move insert. There are some
people that will do an E2 in order to insert
that three move case. However, you want to be
able to do this case from the back if it's a
simple three move insert and that doesn't
require a rotation, which in the previous
video, like I showed you, if the edge matches aside color, regardless if it goes in the
back slots or the front, no key rotation is required. In this case, it would
be the same thing. Simply like that. This case, for example, would need a key
rotation because red matches one of the colors that are in
the front or the back. We would rotate. And you always want to try and insert your slots in the back. Just like this. We have this case here. And this one does not require a key rotation because
the edge matches that. In this case, what I would
do is do a U2 L2 to pair it, inserts, go down and overshoot
to put that pair back. Notice how, when I'm going
through these solves, I'm making sure that I
solve in the back or I don't rotate unless
I absolutely have to. Here's another case here. I would rotate in the
back or you could rotate in the front since
this is the last slot. But keep in mind, any of these that I'm
solving do not require a Y2 which is moving
it two times. If rotation is needed
for any of these cases, it would only be one
rotation per case. You should never have
to do a y2 because that would mean you would
have been able to solve the case from the beginning.
10. Some Rotations Are Acceptable: Now, even though
we're working on eliminating cube rotations
as much as possible, sometimes doing a
rotation list solution is highly inefficient
and not recommended. I just want you to keep
in mind that doing rotations in a lot of cases are totally fine and you don't
want to eliminate them completely unless they are
easy and efficient to do so. For example, this case here, if you separate it like this, you are left with this case. A rotation would be completely fine in order to
solve that case. However, when it comes
to all L and PLL, like I mentioned earlier, do not do a cube rotation
for those or y 2s. There is no need for it unless it's in the
middle of the algorithm. So keep that in mind. Rotations are fine. And make sure that the rotation
list algorithms or cases that you're handling are more efficient than doing
a cube rotation.
11. Closing & What Next?: All right, You guys, that's
the end of my course. I hope you've found this
entertaining and informative. I will close with one more
tip and I highly recommend. What will help you get better is by watching example solves. I have a course up on skillshare already
showing some examples, solves that you might
be able to pick up on some tricks and some
tips from there as well that will help
incorporate a lot of the aspects that I was
teaching in this course. Go ahead and check
out that video. And keep in mind that everything that I have here on this table, all these puzzles in the back, including the one
that I'm using, are available down in
the course description. So you guys can pick some of
the stuff up for yourself. And with that being
said, it's been a pleasure teaching you
guys this course. I hope you enjoyed it. Don't forget to
review the course. Let me know what I did
good, what I did bad. That way I can help improve
