Very quickly becoming the best YT Cuber for tutorials. There's so many of the videos you've done that I had meant to do for years, but watching them you surely executed them much better. Keep it up man :)
+cyotheking thanks! there's a ton you've done and pioneered that shaped what I try to make today. maybe I would have started with something else but you already did an amazing job of it, like how to execute an algorithm like a pro (great series btw). so extra thanks to all you've done for the community!
Wow wow wow wow wow wow. You are my hero. Before this video: How to improve f2l: Watch 100s of example solves and hope for a case you dont know. After this video: How to improve f2l: Oh just watch JPerm's video YOU ARE AMAZING
Here's my counting: I'll take it all rotations of the top layer are treated as the same. So let's instead divide the casework into two cases: one where both Cubies are out of the top layer, and the other where at least one Cubie is in the top layer. Case 1: Neither Cubie in top layer. There are 4 locations and 3 orientations for the corner cubie. There are 4 locations and 2 orientations for the edge cubie. One of these is a solved state, but we'll subtract that off later. This gives us 4 x 3 x 4 x 2 = 96 cases. Case 2: Some Cubie in top layer. Consider the absolute total number of cases. There are 8 corner locations and 8 edge locations. With 3 and 2 orientations respectively, this gives us a total of 384 permutations. We found that 96 of them have both cubes out of the top layer, which means there are 384 - 96 = 288 permutations where one cube is in the top layer. All we need to do is divide 288 by 4 to account for the four rotations of the top layer, which gives us 72 separate permutations. When we combine both of these cases, we get 96 + 72 = 168. Subtracting 1 for the solved permutation gives us 167.
I can't express how grateful I am for this pdf file. I myself have been trying to make one of these for personal use, and it takes a lot of time. Thank you j perm, for this huge contribution to the cubing community :)
I've been cubing for 10 years and only have a few sub 20 solves. I come and go with the community and I'm just getting my interest back. This may be the single most helpful video and document resource I've come across since Badmephisto's original OLL and PLL sheets
Hey J Perm, I would like to say you make really high quality really informative tutorials, well beyond the standards of other cubing RUclipsrs. For example, whenever one of my friends need help I direct them to one of your videos, because they're so informative. I really like how you get to the point, and have solid tutorials. Keep up the good work!
Thank for making this video for F2L, I have practice for over a year on my intuitive F2L solving and I haven't made any significant improvements. This video has shown me a unique way to understand the F2L process better with these assortment of algorithms.
Last year I couldn't even believe it's possible for me to solve a cube in 14 seconds, but now it's my average time! Your videos really helped me to spent less time on f2l, thank you!
@@JPerm Found a mistake. Section 1A 3rd on the right. The highlighted one that’s says y U2 (R F’ R’ F) (L’ U’ L) Should say y U2 (R’ F R F’ ) (L’ U’ L)
I was having huge difficulties getting to sub 10 on 3x3, with this sheet I only needed a few weeks of getting used to the algos and I was much faster immediately! Thanks so much for helping me reach my goal! Please keep on going with your content
I've been searching for a list like this for over a year, thank you. Last slot cases only take me so far; finding solutions experimentally is fun and beneficial but at my stage it can be difficult to know which ones will scale up to speed well. This is gold.
1:09, love how you explain the math behind all of the incorrect numbers of F2L cases. I enjoy learning things much more when I understand why instead of it being like an algorithm where I just have to believe it works and most likely never understand the math behind it. Great job J Perm! :)
In order to be able to remember the apgorithms, first take a short brush over the sheet , just look at it, not trying to memorize, then when you get to a case, try to solve it the way on the sheet without looking at it. Dont try to remember the algorithm, try to visualize how to pair it up without using the long intuitive method. Helped me remember in a couple days! There are only a couple which you really need to memorize, but that just makes the process easier.
Hey, after much of thinking, I found out 167 F2L cases as you mentioned and want to find your opinion. There are altogether 42 cases for F2L (1 which is solved for the correct slot). So, taking 42 cases for one slot and multiplying for 4 slots, we have all total (42*4)=168 cases in which 1 is solved case. Hence, 167 cases of F2L excluding 1 solved case. And also thank you for all your works, it helped a lot.
Thanks to you, J Perm, after only having a cube for about a month and a half, I have a 16 second PB, sub-30 average, and I know full CFOP as well as basic pseudoslotting. Thanks so much :)
I invented a cool f2l trick. Idk if it is actually good, but i love it. If you have a pair that would be in a good place to insert but you would end up inserting into the wrong slot, instead of pushing it over and then cube rotating you can do a wide D move. I use this trick a lot and I really like it. (Note: this isn't strictly for inserting, it can help with pairing too.)
every time i practice i think im getting better at f2l then i watch one of your f2l alg videos and am just baffled how much more efficiently i could be doing this step, thanks so much for the doc!
Thanks for all the tips and tricks i am now averaging 41 seconds and i used to average 1 min. And 30 seconds so THANKS SO MUCH!!! With help from other videos too not just this one
You are my favourite/favorite youtuber and iget really excited whenever you upload. Keep uploading as i look forward to more of your videos(especially how to be sub 10 and f2l algs)
THIS IS MY THREE WISE MEN DAY GIFT!!! THANK YOUUUUU!!!!!!! I will let you know when I'm finally sub-20 Btw, for the 167 cases, if both the edge and corner are in incorrect slots, we have 3 places for corner and 3 for edge, and for each location there are 2 orientations for edge and 3 for corner, so that's (3*3)*2*3=54. Now if one of them is in the correct slot (if both are in correct slot then we counted it in the 41 basic cases) then we have 3 places for the corresponding piece, and again, 2 orientations for edge and 3 for corner. This happens twice since we can have corner or edge in correct slot. This adds 2*[(3)*2*3]=36 cases. Thus there are 54 + 36 = 90 additional cases to the 77 mentioned.
Hey j perm I was sub 30 ....when I started to watch your videos and by the help of your videos here I am sub 20....thanks for the effort you put in your videos cuz these are very beneficial for cubers like me....love you...and your work bro...
I watched the other advanced F2L case video of Jperm and learned it all .when I reached the end of this video . It's like do i have to learn everything again
Good tutorial! I still am not very good at beginners F2L, but I decided to get into advanced early so that I can learn algorithms and get used to them sooner. Thank you so much for the amazing vids! 3:37 the tutorial starts.
This pdf has been really helpful in improving my f2l so far. after i master these algs I'll have to work on my look ahead. thank you very much JPerm!!!
Omg what an amazing video, and literally last night I just started listing through different f2l cases one by one. xD This is going to be incredibly helpful, thank you.
J Perm: I've recently downloaded your algorithm sheet and found that some of the y rotations are incorrectly notated, its confusing becomes some maybe be y or y'. pls fix this
hello j perm. thank you so much for this video, i really liked the tutorial. i practiced some of the first algorithms and i feel more comfortable solving f2l. now im moving to the other 50+ algorithms but i remembered your intuitive approach can help me more understand the logic rather than memorize everything. if i could do both i will be really happy and im excited to show my friends with your tips. thanks from beginner.
4:56 If the back slot is empty, you can also do this: U D' R U' R' D Another algorithm for this case (but messes up the back slot) is, with the edge in the back: R U' R' U2 R U' R' U' R U R'
In the second last case of 1 A you can do R' D' R U'R'D Rand then insert ( the white sticker should be above the empty slot ) the same thing you can do to the last case mirroring the algs
Thanks for sharing. In your pdf document, the very first case on the left has an algo of U2 (R U R') U (R U' R'), a slightly shorter way would be U2 L U' (R U R') L', though you will need two hands.
No. You can easily get below a 25 second average with intuitive f2l. Honestly 41 is only necessary for sub 20 and learning all 167 is overkill unless you are a sub 10 second average
the last case is when both edge and corner are mislotted . 1st case: both edge and corner are together in the wrong slot. no. of permutations : (3)*2*3=18 2nd case:edge and corner in different wrong slots. no of permutations:((3*2)+(3*2))*2*3=72 72+18=90 total f2l cases:77+90=167
This video is awesome!!! Probably the best F2L video out there!!! My F2L is practically flawless now thanks to you JPerm!!! Great Job and Keep It Up!!!
My way to solve F2L is to get the pieces together and just spam R U R’ U’ or L U L’ U’ until it’s either complete or incomplete. If it’s incomplete, I will separate the pieces and insert, if not I’ll just insert it.
After a bit of rime i realized that theres only 94 cases in the PDF. So theres far less then all cases. Could you please add all other cases to the pdf?
+J Perm Nice work on the PDF. Since you asked for suggestions, I have one for the same case as in this comment. A bit long but quick, easy to see an OLL skip coming, and possibilities to do WV/VLS/Edge control after pairing up: (R' D' R) U' (R' D R) U R U R' It's one of my favorite ways of doing this pair :).
Wow, wow, wow! I am wordless to express how brilliant your F2L pdf is! When you think the mechanical intuitive approach is good, this one shows how it is much much better, and you can observe how much progressive it is. It seems like a stepping stone for OLL and PLL, that you can understand how things operate. Whereas OLL and PLL are still too complicated to observe that I can only gurgitate bits by bits, hoping one day they compute like AI in my brain to visualize how things flip around to fit the several aims in one sub sequence. By the way, I saw your "cross" videos as well, could you also kindly if possible make a pdf like this as well; it seems easy in the face of it, but when to be done in millisecond in one single whole action, that's another level of things. Cheers!😃🥰😍
The 2nd last case u showed, u can do that in a better way even if thats the only pair left. 1. Hold the pair in such a way that its on the bottom right(the same holding position j perm showed) 2. Do righty sexy move. 3. Do a Y 4.Do a lefty sexy move.
I've got one algorithm for the case in section 1C. where both pieces are in the slot and the corner is solved, but the edge is flipped. I noticed that all the algorithms that solve the case and don't affect any other pair(s) are 11-12 moves, and the one that's 8 moves (6:44) does affect the slot next to it. The algorithm that I use is 9 moves, and it doesn't affect any other pair while still solving the pair in the slot: (R2' U2 F R2 F') U2 (R' U R').
i dont know of any, but i recommend picking a few that are important, starting with section 1 + all the cases i covered in this video. after many many solves, you'll know when you're comfortable executing them and you can learn a few more.
J perm, in both pieces on top, white sticker faces side / front, stickers on u face is the same, 2nd down from the top right doesn't need the y at the front. Edit: and also for 1 piece in the correct slot, edge in the slot, top right you can just do a U2, sledge it out, U2 and insert
Gosh! Thank you so much. I knew a few of the algorithms in your video but I have learnt new and better algorithms from you. I will never close this tab. Now I can get faster!
2:16 I know I'm super late to the party, but I've been trying for a long time to get this question done, but I finally got it, I hope, here are my calculations Jperm went through why there are 41 cases On last slot, divide the 2 categories: corner on top and in slot So, if the corners in the slot, there are 2 places for the edge to be in, if the corner is on top, there are 5, there are 2 ways the corner can be twisted and 3 ways the edge can be flipped, so (5+2)*3*2-1= 41 Then he mentioned, one piece in the incorrect slot, so, 3 possible places for edge to be in a wrong slot, and 3 places for the corner to be in the wrong slot, so (3+3)*3*2=36 36+41= 77 As before, an edge and a corner can be in the wrong slot, in this category, we can't divide into corner on top or edge on top, but all the cases here are unique, there are 3 possible places for the edge to be in and 3 possible places for the corner to be in, so, (3+3)*3*2= 36 So, 77+36=113 Another category is one piece in the right slot, one piece in the wrong slot, we can divide this into, corner in the right spot edge in the wrong slot, and edge in the right spot and corner in the wrong slot, for edge in the right slot, and corner in the wrong slot, there are 3 different wrong slots for the corner to be in, for edge in the wrong slot, again, there's 3 places, so (3+3)*3*2=36 So 113+36=149 The last thing, this relates back to if both pieces are in the wrong slot, however, the calculation on top does not include if both the corner and edge are joint together and in the wrong slot (I don't know how to join this with the calculation on top, sorry) so, there are 3 different incorrect slots the pair can be in, 3 ways for the corner to be twisted and 2 ways the edge can the flipped, so 3*2*3= 18 149+18=167 There's your answer
Both corner and the the slot flipped or twisted or wrong slot, 4 slots the edge can be in 4slots the corner can be in (4+4) three ways the the corner can be twisted and two ways the edge can be flipped (4+4)×3×2=48,77+48
167-77=90 90 as corner can be in 8 places and edge can be in 7 places 3 ways for corner and 2 ways for an edge so (8+7)×3×2=90 Correct me if i am wrong 😊😊🙏🙏

Here's my counting:
I'll take it all rotations of the top layer are treated as the same. So let's instead divide the casework into two cases: one where both Cubies are out of the top layer, and the other where at least one Cubie is in the top layer.
Case 1: Neither Cubie in top layer. There are 4 locations and 3 orientations for the corner cubie. There are 4 locations and 2 orientations for the edge cubie. One of these is a solved state, but we'll subtract that off later. This gives us 4 x 3 x 4 x 2 = 96 cases.
Case 2: Some Cubie in top layer. Consider the absolute total number of cases. There are 8 corner locations and 8 edge locations. With 3 and 2 orientations respectively, this gives us a total of 384 permutations. We found that 96 of them have both cubes out of the top layer, which means there are 384 - 96 = 288 permutations where one cube is in the top layer. All we need to do is divide 288 by 4 to account for the four rotations of the top layer, which gives us 72 separate permutations.
When we combine both of these cases, we get 96 + 72 = 168. Subtracting 1 for the solved permutation gives us 167.

In the second last case of 1 A you can do R' D' R U'R'D Rand then insert ( the white sticker should be above the empty slot ) the same thing you can do to the last case mirroring the algs
I think I`ve found a mistake in the PDF
Section 2B
Corner in the back slot:
(R U' R') U (L U L')
Solution:
(R U R') U (L U L')
Ayo imagine someone grinded it out entirely and shouted and unsubbed cuz it didn't work
Thanks for sharing.
In your pdf document, the very first case on the left has an algo of U2 (R U R') U (R U' R'), a slightly shorter way would be U2 L U' (R U R') L', though you will need two hands.
Can you please make a PDF for all 167 cases? Thanks.
I'm just starting speedcubing and wants to ask if I have to learn every algorithm?
No. You can easily get below a 25 second average with intuitive f2l. Honestly 41 is only necessary for sub 20 and learning all 167 is overkill unless you are a sub 10 second average
the last case is when both edge and corner are mislotted .
1st case: both edge and corner are together in the wrong slot.
no. of permutations : (3)*2*3=18
2nd case:edge and corner in different wrong slots.
no of permutations:((3*2)+(3*2))*2*3=72
72+18=90
total f2l cases:77+90=167
OMG this is too great video friend waiting for this
This video is awesome!!! Probably the best F2L video out there!!! My F2L is practically flawless now thanks to you JPerm!!! Great Job and Keep It Up!!!
MyF2L algs are from 2018 but these are from 3018
My way to solve F2L is to get the pieces together and just spam R U R’ U’ or L U L’ U’ until it’s either complete or incomplete. If it’s incomplete, I will separate the pieces and insert, if not I’ll just insert it.
After a bit of rime i realized that theres only 94 cases in the PDF. So theres far less then all cases. Could you please add all other cases to the pdf?
For Section 1C case #2 (top right) I use:
R2 B R' B' R' U d R' U' R
Basically R2 B R' B' R', U2 + rotation, then insert.
Also mirrored for 1C #4.
Why doesnt the PDF exist anymore?
J perm is literally helping to start my speed cubing thank you dayln wong
3:50 Just do U R' F R F' U R U R'
It's basically U Slegehammer the insert
+ROEVOSS good one. thanks!
+J Perm
Nice work on the PDF. Since you asked for suggestions, I have one for the same case as in this comment. A bit long but quick, easy to see an OLL skip coming, and possibilities to do WV/VLS/Edge control after pairing up:
(R' D' R) U' (R' D R) U R U R'
It's one of my favorite ways of doing this pair :).
The alg he has is better for the ZBLS he showed, your alg solves a different one where the usual alg is: (F' U F) U2 (R U R').
Just do Sexy U' R U' R' insert
Wow, wow, wow! I am wordless to express how brilliant your F2L pdf is! When you think the mechanical intuitive approach is good, this one shows how it is much much better, and you can observe how much progressive it is. It seems like a stepping stone for OLL and PLL, that you can understand how things operate. Whereas OLL and PLL are still too complicated to observe that I can only gurgitate bits by bits, hoping one day they compute like AI in my brain to visualize how things flip around to fit the several aims in one sub sequence.
By the way, I saw your "cross" videos as well, could you also kindly if possible make a pdf like this as well; it seems easy in the face of it, but when to be done in millisecond in one single whole action, that's another level of things. Cheers!😃🥰😍
jk your videos are gr8
The 2nd last case u showed, u can do that in a better way even if thats the only pair left.
1. Hold the pair in such a way that its on the bottom right(the same holding position j perm showed)
2. Do righty sexy move.
3. Do a Y
4.Do a lefty sexy move.
i cant believe how you haven't reach 1mil yet
come on guys he deserves it
Perfect, between all the Advanced F2L videos of all youtubers, it's hard to begin
0:52 wow u liked ur own video
he wouldn't dislike his video that's logic
@@anthonygraindedreux-beauss5887 I know🤣🤣
I've got one algorithm for the case in section 1C. where both pieces are in the slot and the corner is solved, but the edge is flipped. I noticed that all the algorithms that solve the case and don't affect any other pair(s) are 11-12 moves, and the one that's 8 moves (6:44) does affect the slot next to it. The algorithm that I use is 9 moves, and it doesn't affect any other pair while still solving the pair in the slot: (R2' U2 F R2 F') U2 (R' U R').
My heart broke after reading "167 cases"
zb is more
Section 1C. Bottom left case. The alg i use is: (R2 U2 F) (R2 F' U2) (R' U R')
Starting with thumb on top. Extremely fingertrick friendly.
Some of these I just found out myself without any videos when I was a noob, 😂
I like the way his vids are downloadable, that way I can watch his vids anywhere and anytime
Who else just learned the F2L cases themselves
me lmao
Been waiting for something like this for ages. Thanks so much 👍👍
How would you practice all of these cases for f2l? Is there an f2l trainer that can help?
i dont know of any, but i recommend picking a few that are important, starting with section 1 + all the cases i covered in this video.
after many many solves, you'll know when you're comfortable executing them and you can learn a few more.
tysm I had the same question
on qqtimer, u can go to 3x3 subsets and select f2l. u can then practice f2l using that subset. hope it helped! :)
For edge insertion of beginners method we can another alg which reduces F moves. That is ( RU'R'U'RU'R'URUR'). For the case in the video at 5:14
exuse me j perm, in section one the first algorithm to the right can be solved with r U' r' U2 r U r'
Yup
J perm, in both pieces on top, white sticker faces side / front, stickers on u face is the same, 2nd down from the top right doesn't need the y at the front.
Edit: and also for 1 piece in the correct slot, edge in the slot, top right you can just do a U2, sledge it out, U2 and insert
6:53 I do Sexy Move until is solved and after that I just insert it.
I would not recommend it because it can hinder your look aheaf
Gosh! Thank you so much. I knew a few of the algorithms in your video but I have learnt new and better algorithms from you. I will never close this tab. Now I can get faster!
Listen to his voice on 0.25x speed 🤣🤣
Dude check on 2x, btw 0.25 is f
Gud

I know I'm super late to the party, but I've been trying for a long time to get this question done, but I finally got it, I hope, here are my calculations
Jperm went through why there are 41 cases
On last slot, divide the 2 categories: corner on top and in slot
So, if the corners in the slot, there are 2 places for the edge to be in, if the corner is on top, there are 5, there are 2 ways the corner can be twisted and 3 ways the edge can be flipped, so (5+2)*3*2-1= 41
Then he mentioned, one piece in the incorrect slot, so, 3 possible places for edge to be in a wrong slot, and 3 places for the corner to be in the wrong slot, so (3+3)*3*2=36
36+41= 77
As before, an edge and a corner can be in the wrong slot, in this category, we can't divide into corner on top or edge on top, but all the cases here are unique, there are 3 possible places for the edge to be in and 3 possible places for the corner to be in, so, (3+3)*3*2= 36
So, 77+36=113
Another category is one piece in the right slot, one piece in the wrong slot, we can divide this into, corner in the right spot edge in the wrong slot, and edge in the right spot and corner in the wrong slot, for edge in the right slot, and corner in the wrong slot, there are 3 different wrong slots for the corner to be in, for edge in the wrong slot, again, there's 3 places, so (3+3)*3*2=36
So 113+36=149
The last thing, this relates back to if both pieces are in the wrong slot, however, the calculation on top does not include if both the corner and edge are joint together and in the wrong slot (I don't know how to join this with the calculation on top, sorry) so, there are 3 different incorrect slots the pair can be in, 3 ways for the corner to be twisted and 2 ways the edge can the flipped, so 3*2*3= 18
149+18=167
There's your answer
thanks for the explanation.
Wow lol
Hey the 41 case? Why the edge can only be in 2 places in the slot? I think the edge can be on 5 places right?
@@Doom_Guy_Slayers because for corner in the slot,the 4 edges on top are the same cases
Both corner and the the slot flipped or twisted or wrong slot, 4 slots the edge can be in 4slots the corner can be in (4+4) three ways the the corner can be twisted and two ways the edge can be flipped (4+4)×3×2=48,77+48

Thats why j perm is my favorite RUclips cuber
This is the best J perm video ever!!
4:42 on that case, instead of inserting with URU’R’, I did a sledgehammer with an extra U, I did that because I saw it would finish my next pair.
167-77=90
90 as corner can be in 8 places and edge can be in 7 places 3 ways for corner and 2 ways for an edge so
(8+7)×3×2=90
Correct me if i am wrong 😊😊🙏🙏
This was simple permutation taught in class 11th BTW
