► Swapping Algorithms
Center: U2
Wing: r2
Corner: R U' R' U' R U R' F' R U R' U' R' F R

► Swapping Rules
- Check below for setup moves
- For most cases, do setup + swap + undo setup
- For special cases, do only the algorithm shown
- If B/D comes 2nd in a letter pair during centers, swap to the other one instead.
- If I/S comes 2nd in a letter pair during wings, swap to the other one instead.

► Parity Algorithms
Center: U2
Wing: r' U2 r U2 r' U2 x r U2 r U2 r U2 r2 U2 x' r' U2
Corner: U2 R U R' U' (r2 U2 r2 Uw2 r2 Uw2) U' R U' R' U2

► Parity Rules
- If memorization for any step (centers/wings/corners) has an ODD number of letters, then execute the parity algorithm after that step is completed.
- Parity for one step does not imply parity for any other steps. Each parity is independent of the others.
- Follow this order for execution: Centers - Wings - Corners. If you do not, the parity algorithms may mess up other pieces!

► Center Setup Moves

E: r u r'
F: y' u r' u' r

U: (special) D [swap to V] D'
V: (special) Lw' U' r2 U' l U r2 U' l' U2 Lw U2
W: (special) D' [swap to V] D

tip for centers, when It's odd, add a "C" to the end of your memo. It helps make it stick better and makes it so you won't forget parity.

[tamelnv]

Me: Parity algorithm? WHAT'S THE PARITY ALGORITHM OH NO!?
J Perm: U2
Me: OH YAY

[alejrandom]

2:56 this alg is easier for D layer pieces:
r2 D' r2 D r2 (U2) r2 D' r2 D r2
edit: yes it is a bit slow, I use 3style, but it's easier for people who are just starting 4bld

[janakpalit]

Thanks for this wonderful tutorial... Got my first 4bld success of 15:42 after 12 attempts...👏👏😃

[thomasschmidt]

Every time you make a video about a certain event, I become extremely interested in that event

[queijoduke]

Thank you J Perm! Thanks to this tutorial, I got my first 4BLD success (30:31) today!

[sritejpaini]

Thanks J Perm, got my first success in my very first attempt, really helpful tutorial.

[ninruelos]

Holy cow i didn't know this until now because last week i was searching for 4 bld tutorials but none of them were that high quality. and then I see this. Thanks man you are my savior! :D

[devanshgadda]

I am a simple man, I see J perm has uploaded, I like.

[Gretchaninov]

Yes!!! I did it! This tutorial is perfect. I got 16:33 on the first attempt. Probably overly cautious when remembering and turning but it paid off! This was after a month or so of practising of course (edges only, centers only, 4 edges at a time, etc).

[joyneelrocks]

Awesome vid Dylan. Was very concise n easy to understand. Btw for [Q] in r2 method for the edges / wings, instead u can use an easier n more comfortable setup to [V]: B' R B (U R2 U') r2 (U R'2 U') B' R' B. This alg is much more intuitive n easier to understand abt what's happening during the setup...

[ItBeOnai]

I think for wings it's better to think about them as "the same letter for the color/piece as you would with 3bld". So the white of the white/blue would be A for both, and the further along clockwise rule is to see which piece you need to look at next. That's how I think about it and it made it much easier to memo for me

[nicholasbaker]

Just in case anybody is having trouble learning the top face centre swap, I put the "B" case into commutator notation:
[Rw' F': [U r U', l']]
If you have B or D in memo, then do this commutator but if *a)* B is 2nd letter in letter pair or *b)* D is 1st in letter pair, then do the inverse

Inverse for convenience:
[Rw' F': [l', U r U']]

[ezioauditore]

Dude, congratulations! Yours tutorials videos are amazing.

[sachilabbimane]

I normally watch every one of your of your videos as soon as they are out, but one look at this and I knew it was beyond me.

[Kroltrox]

Oh boi, I can't wait for the 21x21 blindfold solve tutorial

[Whydidtheychangeittohandlesnow]

This is the only full tutorial on YouTube. Finally I can learn.

[el_sancho_]

Wow never thought you’d make a 4x4 blind tutorial I already liked the video and don’t know what’s going on

[howdayhoototot]

Thank you for making this video! Highly appreciated! Love all your content and im always hyped for more! Fav youtuber!
