- Matching stickers makes you track too much information at once. I show a method where you track less info, making look ahead much easier.

0:00 How
1:11 Recognizing cases faster
3:48 Save rotation time
4:20 Corner in opposite slot
5:48 Predicting first pair
Recognizing orientation is not ALWAYS better than matching stickers or any other way. A lot of my recognition comes from "intuition" or "I just know", but the orientation technique is the best way I can explain where that intuition actually comes from.
For predicting first pair during inspection, this recognition technique is the #1 reason I can do it in under 15 seconds.
My cross to F2L video with examples (using this technique):

Thanks!
Hey J Perm I am sub 40 and I use 4LLL and take around 5 sec for cross, 25-30 seconds for F2L, and the rest for OLL and PLL(It is my first month of cubing.) I have watched about every video I can find that says how you can improve F2L but still I can never. I am sorry that I have asked this question about 2 times before and you always answer so thank you but I don’t know what to do now. I really like cubing but I might end up quitting because I can never improve.
What you need to do is to completely stop timing yourself, and just practice F2L, by just doing cross, and finding more efficient algs. LazerMonkey's every F2L case explained intuitively is a great place to go to. Other than that, example solves the only way to go.
Apart from J Perm's Best Algorithms for ALL advanced F2L Cases pdf
Krish Vijay it takes time to improve. If you've only been cubing for a month thats nothing. Keep practicing and learn full oll, pll. Good f2l comes with time.
J perm,can u explain wht is oriented,i dont understand ,u was saying the word over and over, and iwas like ,dhek is tht
This is amazing, thank you. I'm going to have to watch it about 20 more times. 😂
I understand nothing
@@haivvn10 I am a beginner man....please be nice to me...
@@haivvn10 Mind your words and if you want to reply, be proper or else no one is waiting for your reply here. Get lost.
That just increases his watch minutes 😂
Me too
This is the exact technique that I have been using for months. When I was experimenting with cfop it just came naturally for me because zz relies heavily on edge orientation.
same here, except roux for some reason! I saw eo naturally after switching back from roux a long time ago.
Lol. Me too, I thought this was something everyone already used.
What's funny is that I actually use the top color to recognize a good/bad edge faster. I initially used your method of recognition, but I found myself glancing left and right too often which was somewhat tiring. So now I just look at the top color of the edge & the front center color facing me. They must be the same or opposite, else I rotate! But thanks for your videos anyway...they're super helpful ^_^
This makes more sense to me since you can always see the top without having to glance at the sides
same
im going to try your method right now
Wow, amazing job continuing to create beautiful, short videos. I used to be a fanatic for the Rubik's cube, but then I lost interest. And now 8 months later, I'm thinking of finally putting some serious work into my F2L. Especially look ahead, which you so generously are giving advise on in nearly every video.
thanks, and glad you're interested! have you considered blindfolded/one hand?
Really helpful! Thanks!
CrazyBadCuber, Hi
True, but I never used it.
i'm so late to this video, but thank you so much for making content like this for everyone!! i know you're not as active here anymore, but i just wanted to say your channel has been such an amazing help to me, and i'm sure many other people, and i really can't thank you enough for all you've done for the cubing community.
all the effort and hardwork you put into your videos is just incredible, and i'm sure you'll do well in whatever you decide to do wherever you go! you'll always be someone who inspired me a lot, and encouraged me with your videos even though you may not know it. i want to wish you the best of luck with everything, and i hope you're doing well!
you are amazing, and i hope you always remember that! thank you for your comforting videos during a difficult time in my life.
When you get that sexy 10 second solve with flawless F2L look-ahead and a J-Perm.
For me it’s t perm
for me its Y perm. For some reason I go on a streak of T perms, a G perm, and now a Y perm
And then it's an awkward shape or dot case OLL.
i got a 9.05 single with an x cross, 2 free pairs, oll skip and ended up with j perm sheeshhh
for me if my cross is efficient and fast it for some reason affects my solve a bunch, if I have a mid cross solution I get around 20 seconds, a good cross solution around 15 seconds, and a bad cross solution around 25, even if the cross doesn't take that much time
This is immensely helpful, thank you! And it made me realize that this also applies to an edge that is in a slot with the corner on the top (i.e. if doing an R or L move to bring the edge up makes it a bad edge, then a rotation is needed). Brilliant stuff
thanks for the vid!!! my lack of look ahead has really been holding me back, and this vid is really helpful!
Thanks, this is going to help so much with my F2L. Also, I loved the way you filmed the solves in the end, it made the video seem very professional.
God this is brilliant, it really helps and nowhere else I would find this
I hope you’re making a living from youtube as your videos are so useful! Every time I’m ready to learn a new technique I come to your channel!
I felt something was missing in my F2L look ahead. This is just what I needed, thanks !
No one talks about this and imo it's really important for the 9-12 second range. Gj on making this!
I always thought that your previous video on this topic was really good, but was still a bit confusing in some parts. This is much better :D
This is gonna help, my F2L needs to much work, my look ahead too, sometimes I catch myself doing tons of turns on one case and just think to myself after wards like “There was definitely a waayyyy quirked way to do that”
Dude now I feel like I learned f2l all wrong lol
thanks for the vid J
You're the best. today I thought: I have to improve my F2l and you made this vid
Fantastic analysis. It helped me a lot. Thanks
WOAJ! Just when I thought that my algs were what i needed to improve!
Corner twist cubing your pfp gives me ocd 🤬
It was 3.am in Vietnam when you uploaded this video :D
THANKS jperm, this video appear at the perfect timing. currently sub 16
This is the most useful video I’ve ever watched
Who else is coming from the solve critique of October 2020?
Cuber Cuber on the wall who makes the best tutorials of them all? It’s you Jperm, it’s you 😂😅
Amazing video this will definitely help me with my F2L. Thanks you always make amazing videos.
it’s actually refreshing trying to learn color neutral and EO line at the same. it’s like the same experience all over again
This is some mind blowing info. Thank you very much!!
A great video, thanks for remaking it!
Can you talk about in the future about corned and edge biased? I found an excellent discussion in the speedsolving forum, the title is: "Most optimal way to find and handle Fridrich F2L pairs (Intuitive)"
I think using corners is very natural, but using edges first also works once you get the hang of this orientation thing, because you never have to re-recognise the edge later on.
This is very cool. Will practice this more once I get faster and better at efficient f2l inserts
J PERM I DONT EVEN HAVE TIME TO WATCH THIS BECAUSE I HAVE TO GO SOMEWHERE BUT I SAW THAT YOU UPLOADED SO I JUST AUTOMATICALLY LIKED AND LEFT THIS COMMENT I FUCKING LOVE YOU
LOL THANK YOU
Heres something I found that usually helps to avoid rotations: when you have a 3-move insert but your pair will go into the wrong slot (i.e. your 3 move insert is for the blue-orange pair but the slot in front of you is the blue-red slot), where istead of doing a rotation you can sinply do a wide D or wide D’ to move the slot, and not the pair. However, this may hinder you lookahead depending on how far in to f2l you already are.
GCubes but that will require a regrip to do d move then another to execute. only one regrip with rotation
If you have a bad edge, you can pair them up and then insert using f R' f'. I saw it in Feliks Zemdegs 3.33 solve. Still really helpful! Thanks!
yeah any F move can turn a bad edge into a good edge. Doing a cube rotation with RUL moves is usually considered faster than doing F moves. But you can definitely use F moves if you want
I am a little late to the Party, but i am amazed how useful this is. I am having a hard time with f2l, especially look ahead and finding pieces, so this in my first try already seems to help a Lot!
same here
Wow !! ZBLL on last solve before ending
I’ve been waiting for this tutorial for a long time now thx bro keep up the amazing f2l videos!
Sir,to recognise the EO FASTER,YOU CAN LOOK AT THE FRONT CENTER AND TOP COLOUR OF THE EDGE PIECE ON THE TOP .IF IT IS MATCHING ANYWHERE ON TOP EDGE POSITIONS OR JUST THE OPPOSITE COLOUR YOU DON'T HAVE TO ROTATE AS IT IS ORIENTATION AND IT IS EVEN FASTER THAN LOOKING AT THE SIDE AS I THINK SO.
5:05 you could do U' and a lefty sledgehammer that pairs them up and then R' U2 R to insert it without having a cube rotation ;)
Hi j perm i watched many video of felikes and in the video he said that this edge is oriented and this is not oriented and i did not understand that but in this video i got it thanks j perm
That was very helpful thank you! I am going to practice that!
This is sooo god it’s what I needed to start being color neutral
I'm going to watch your cross to F2L video multiple times.
Great video! I've always had trouble with F2l lookahead
WOW! This is so cool! This is so eye opening for me!
Thats nice and all but i do F2l by using Algorithms, so my entire solve is basically algorithms. how do I do EO with algorithms?
J PERM: Faster look ahead BLAH BLAH BLAH...
HIS LOOK AHEAD AT THE END CLIP: SLOWNESS III
LOL XD
I love these vids plz do them more
Nice!You helped me from average 25 to high 9 because of you!Liked and subscribed!Do a walkthrough solve video
Vichev Jr Bro you think 25 is bad. I average 47 and I use cfop 2 look OLL and PLL. I have practised cfop for over a month and a half and I never get faster. Any tips?
Wasp Boy14 I average 23s with 4LLL
learn to look ahead and do medum to slow f2l and practice more 4x4
Vichev Jr Ok thanks I'll try to practise look ahead and move medium, make sure Im always making efficient turns.
it's super helpful !!!!! thanks a lot keep uploading these type of videos and once again thanks
2:40 You don’t need to rotate right away. You can pair them up with R’ U2 R & then insert with a hedgeslammer on the left.
Bro he also talked about RUL moves
thanks j perm i think i m improving my f2l now
J Perm - The Einstein of Cubing
Thanks
I knew you had a video explaining this it took a while to find😅
Helped a lot tho👍
Good info. A video of how wich sides yoy need to turn as not to undo a solved edge pair
Hey perm glad to learn this method
Great video! Really helpful. Can i ask what should I learn after full OLL?
nothing is necessary, the best would be practicing f2l and drilling LL algs. but COLL is definitely the best alg set after OLL
how about full one look PLL? is it worth learning before coll
oh that should be learned before full OLL!
ok thanks!
Lol, Collin burns uses pure cfop (no Coll, no vls, nothing) and he's still sub 8
This is amazing intuition! Thank you! Can't wait to master this
Thank u so much for this vid JPerm
An easier ish but a little less helpful way of doing this is: if the side color on the edge is opposite of the color of the face you are facing, you will have to rotate to insert or use one of the two rotationless inserts. This is useful for me because for f2l I just focus on pairing the pieces up and then inserting, which may or may not be a bad habit.
with your way, technically we will have rotationless f2l(use wide f moves to insert in back)
Nice! though I think it might be a bit easier to look at the top sticker and see if it matches the front or back centres, so we can know its orientation no matter where it is in the U layer :D
You’re not supposed to start or stop the timer while touching the cube because there’s a chance that you can actually turn the cube before you start the timer, which is why that’s the rule in the WCA.
Very, very interesting video, as most of the stuff you create. I think it could be useful for me and I'm ashamed I never thought of it myself, as I know the basics of ZZ and Petrus. Just two comments. As others have already commented I'd put it as top color of the edge is either front or back --> oriented, instead of side color is side color, for example, if the edge is in UB I cannot see the side color but I can always see the top color. Of course, if the edge is in one of the front slots then it's front color what I need to check against front / back centers. Anyway, if I need to extract the edge from back right I will have to check on side color, which is the one I will be seeing, to know whether it's comming on top oriented or misoriented. And, also, regarding misoriented edge -> cube rotation, there might be cases where a sledge hammer to orient it could be an option as well if it is either inserted in a front slot or in UF. Thanks for your great content!
Glad you liked it! I personally prefer side color only because the side color can touch the side center as it moves, making recognition easier in many cases; less thinking. It's invisible when the edge is at BU, but the pieces are always moving so I don't think that's a problem.
And you're right, avoiding rotations is definitely better when possible!
You're absolutely right about both things I guess!
That’s a very long comment
At 3:36 isn't that the same case as when you put the edge on the front? The red edge side still matches the red on the right of the cube. Did you mean to flip the edge?
What timer are you using in your computer? I would like to know.
This is great. I will put this into practice
Thanks for remaking this video!
I've been workung on more wide moves to avoid rotation, however sometimes it feels like it would be faster to do a rotation or a d turn to put a slot where I need it?
Do you feel a d turn is good if it lines up and inserts a pair faster than a wide turn?
Too many d turns or rotatatins take up time and cause me to have to search harder for f2l pairs, but one when efficient should be worth it, right?
Are you actually colour neutral? I spent a few months becoming colour neutral (solves with my new cross colours are now only 3 or so seconds slower than my usual cross colour) but I just can't be bothered anymore. Should I just revert back to my OG colour?
To recognize if the edge if a good or bad edge is that if you aee the edge (front color) is the oppositeor the same color then it is a bad edge if it is not then it is a good one
Thats simple and helpful
which is perfect
thx! :)
btw when can we expect the next cube critic vid?
not for a while, I have some stuff to sort out about how to organize that stuff for this channel
J Perm u could come up with a schedule maybe?....
Do you have plans showing how you setup your cube?
PS. The first video was very helpful. ;)
Omg this soo good :v i am practicing look ahead but too slow 6 months and dont have many up :/ after see i feel like my brain blow up, i just look at the edge to see does it match with the otherside, this fast thank bro
Decreasing my time as much as possible, trying for Nationals thx
if the side color matches with the center color benaeth it, you can do a sledghammer and then do a keyhole
I have one tip if you have green or blue in front or back that means if you have any green or blue egde facing up it means it good egde no need of rotation
Cool! I needed help with look ahead!
This is a great technique! I understand how it's being used for predicting first pair, but I'm having trouble adapting it to look ahead. It seems that the amount of time it takes for me to figure out whether an edge is good or bad takes just as long as figuring out what the appropriate case is using matching stickers, especially with color neutrality. Do you have any tips on how to resolve this?
the reason this is good is because you can identify good/bad edges before seeing your final f2l case. as soon as you spot an edge you can notice its orientation and just remember that for later
if you're recognizing it after solving the previous pair, then that's too late
Thank-you so much.
this is help me lot
Thanks! This is very useful since im improving my look ahead.
what sub are you
Ayen Ng Sub 13
my name is not ayen...is my mothers name and im using my mom phone...also my name is rys and im a boy from sabah
Ok
😀
Nice vid! Also are you ever planning on doing 6x6 or 7x7?
i started 6x6, 7x7 shouldn't be for a while. I still like 5x5 more but 6x6 kind of goes on in the background. check bit.ly/JPERMPBS if you ever want to know what I'm working on!
Great video! I'm wondering if something similar exist for good and bad corners, and how to recognize it. So you already know if you have to rotate before seeing the edge.
no, because RUL can change the orientation of corners but not for edges. also, corners don't affect whether or not you need to rotate :)
Thanks!
Honestly if you start doing this, you might as well learn. ZZ has entirely pure benefits minus Eo+line being 1 move slower than cross max. Since youre already used to recognizing which edges are good and bad and can learn EO very easily. All it takes is practice for EO+Line. F2L will never have rotations and has less cases. And you can block build pairs and edges in. So F2l is more open, which could be more difficult, but also makes for really efficient f2l(ive done f2l in 17 moves and im not good at solving, my average is like 18, so somebody definitely could do it better, in like ~13/14 moves), then you are guaranteed to get yellow cross which has only 7 cases. Then normal PLL
I disagree, because it's general consensus that zz is slower than cfop for 2 hands. you definitely don't average 18 for f2l unless you're excluding eoline. cfop cases are generally easier to execute due to fewer regrips, OLL is pretty much the same speed either way, so you need a huge number of LL tricks for ZZ to match CFOP.
Thanks for the helpfull videos. I got to sub 30 in 5 months just because of your videos.
WOW!! That's the word. Thanks for that man. I wonder if you came up with that?
I came up with it myself, but I'm sure many others have as well.
Wow this is a really useful technique that was explain well
Thanks a lot for this; very helpful!
i've been struggling to remember all the algorithms for F2L, do you have any tips for remembering them?
Just drill the hell out of the algs, it may be boring but your muscle memory will do the work for you
understand them
Put a chart on algorithm Everytime you get the case watch it and move, if you keep on doing it your muscle memory will pick it up and don't need to memorize.
First do a handscramble and visualize and find the best way to do the case
Repeat it again and again to get it into muscle memory
Wow this brought my avg from 30 to 22 thx
For people struggling- try learning zz and doing a few solves, this will be much easier :)
nice tutorial! really nice for me to break the barrier of sub15 anyways whats the cube u have
glad you like it! the cube name is always in the description.
Hello, Dylan! I found a mistake in your pdf file. Advanced f2l, section 2a, white sticker faces side/front, right column, third case. The first formula should start with "y", and the second shouldn't have any rotation at the beginning.
🤝
I want help. I'm used to make f2l with the white on bottom and it takes me more time to do f2l with other colors. What I should try to do?
Thank you j perm
This is good stuff!
What is the software that you use like a timer?
Great video! Yet I still have a question. In the beginning, you said that a 3 move insert did not require a rotation. What if the edge was not oriented in the 3 move insert, wouldn't you still have to rotate? Same with the second case, where the top colors are the same, you could end up where the edge is oriented, so how exactly does looking at just the edge determine the case?
if the edge is bad, you can't do a 3 move insert without rotating unless you use F moves
Ok. After posting this, I realized after a bit that this is the method I actually used, I just didn't realize it. Thanks anyways. LOL
oh a perfect match! 4:37💖💖💖💖💖
Thank you J perm
have you seen the sub-20/15 videos?
It helps a lot.
Thanks jperm.
Oh tips pls
JPERM, I think I 💜 u lol
