For the third layer edges, you can still do the same 3x3x3 algos you did for the 2nd layer, coupling the two bottom layers instead of the two middle layers.
Did anyone else notice that his intuitively derived algorithm R b U b' U' R' U b U' b' is actually a commutator? A - R B - b U b' U' A' - R' B' - U b U' b' Algorithm is A B A' B' BTW b is indeed used for that layer however prime means counterclockwise. And since it is a back layer you have to look at it from the back, so what he did was actually clockwise, not counterclockwise, so it should be b, not b'.
I think he was actually referring to the inner back slice when he said "b", but he kept rotating the cube so much that it's orientation was hard to keep track of. He even lost track of it himself by the end. He's definitely using "b" for the inner back slice when he writes his second algorithm, tho.
It's really interesting to see your process for solving these puzzles. In the past couple months I've started getting really into twisty puzzles, partly thanks to this series, and watching you solve the 4x4 layer by layer like this is so much different from the speed methods I've seen elsewhere (from what I can tell almost everyone uses some variation of redux). Depending on how mush trouble the last layer gives you with this method I might start using a layer by layer method for fun on my 4x4.
I forgot I had flux on my laptop and for a solid 8 minutes was wondering why someone would make a rubix cube with a light green, dark green, white, orange, another white, and red color scheme
Lol, you have to lower your settings on Flux x) It shouldn't change that much, it should only lower it enough for you to not completely burn your eyes.
I have also made intuitive solving of 4x4 and I took me quite some time. I found a bit simpler way for the 3rd layer edges I think. You apply the 3x3 algorithm in the first steps, but then save the b layer , finish algorithm, restore b layer. I use it for 5x5 layer as well with minor adaptations. I really like these videos!
Wow you're cranking the videos out this week! Loving it! I've never thought of trying to do the 4x4x4 layer by layer. I've always just used the reduction method. Might have to take a shot at it for fun.
Sophie Grey the cubicle.us is a great place to buy puzzles, but be sure to check out some reviews of puzzles. The cube used in this vid is called the mf4
Nice video, and I admire that you are trying to solve it intuitively, but just bear in mind that it's much easier to solve via the reduction method (reduce the centers, place them properly, reduce the edges, solve as a 3x3x3, and deal with the possible two parities if you get them). Using the beginner's method (without any speed-cubing techniques) you could solve it this way within 3-5 minutes.
The slice moves are the lowercase version of the outside move next to it. So the slice next to L is l (not capital i) and the slice next to R is r. The slice below U is u, etc.
Man these are your best videos...they are very beautiful and i really like your way of thinking...perhaps i love intuitive...keep on going for the 4x4x6 fisher cube💪
Hi Fleb, the way you found out how to do the centers in the second and third layer reminds me of the 'swinging-U' technique which is often used by superantoniovivaldi. See for an example for what i mean: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CGgwWiRWhto.html and start at 09:33. Great video again!
Hey Fleb! I don't mean to sound like a weirdo, bit I love watching your videos when I get off work. I take a Xanax, and just watch you solve, and explain various puzzles. Anywho, I appreciate what you do man.
With basically any n*n*n cube I am able to intuitively find a solution for every layer but the last one. That's usually where I get stomped then. I was able to solve it on the 3*3 and was then able to solve it on the 2*2 the same way but anything above that will probably get problematic.
