What a great tutorial! Easy to follow because you nailed the explanations and comparisons to a regular 2x2x2. It may be too fast in places, but one can just rewatch it. I think when someone understands some basic rules, the puzzle can become fun and easy.
Thank you! Glad you liked it :)
wow i've been into cubing for a few years now, and never heard about physical 4d cubes, thats awesome, i need to add this to the collections and try speed solve on this
When you took off the smaller piece, my mind blew up.
Thank you so much for this tutorial! It was very easy to follow, made sense, and helped me a ton in solving my own 2x2x2x2 I got a few days ago!
I love you Rowan. You truly inspired me into existing in the world. Your video is really one of the videos ever.
Thanks for the tutorial! It helped get me started with my new 2^4 cube. I was surprised how naturally the solve goes once you understand a few basic principles. I ended up combining your method with the beginner 3d method and some intuition to get my first solve!
really wishing i had this puzzle. block building looks fun, and intuitive (kinda) and satisfying as hell
You're amazing, just solved my 2x2x2x2 for the first time and it feels incredible!
Awesome stuff Rowan!!
I had to wear headphones for this video so my melted brain wouldn't pour out of my ears.
I havn't watched this channel in over a year. getting so close to 3k!
Awesome!
pov: you watch this before getting a 2x2x2x2…
RKT parity alg doesnt need to be that long, u could just do R L' using RKT on the left side
no, that doesn't work
@@RowanFortier i just tried it and it didnt work
I love it
Wow thanks if I get 4d 2x2 than I'll watch it after that I'm gonna see advanced one too
Awesome
21:56 I keep getting a situation where my one corner stays as one when I gyro
I just peel the stickers off
10:56 "just reorient to the top side" 🤯
I wonder what does eg method look like for it
Can you twist one grid of squares by 180 degrees?
Do you have an algorithm for RKT parity with a 180° twist ? I kind of solve it by using yours for the 90° twist and additional random twisting but that's not very efficient
Actually a 90 degree twist of a single layer is an impossible case. I show my algorithm for 180 RKT parity at the end of the video about 31:40 I think :)
@@RowanFortier Oh, you're right... I guess it means I suck at following instructions then
@@RowanFortier Well I've been solving my cube quite a bit lately and I do stumble unto parity cases with a 90° twist, I don't know if I'm doing something wrong for that to happen, but if you ever find an algorithm for this case it would be much appreciated dear sir.
@@KardEroc As I said, that is an impossible case. Make sure you are following the canonical moveset very closely
This freaked my bean 🤯
poor bean
4d sune!!
Imagine a blind kid solving this with all the colors possible being shown
Can a cardboard 2x2x2x2 work without magnets? I think it works but with bad turning and a need too be careful too not fall apart
I have made one out of paper with magnets and that works really well
Does this method work for the virtual 2x2x2x2
Yeah
I only want this for the magnets 🙃
How can you do it online? If you don’t have one
Currently there isn't a simulator for the physical 2x2x2x2, however there are obviously the virtual programs for the puzzles. Akkei made a program for the physical 3x3x3x3 though
@@RowanFortier I think they're wondering how to solve a virtual 2x2x2x2. I came here because I couldn't find a tutorial for it either. If you could make one, that would be amazing!
While I'm not a huge fan of RKT, as it feels like I am not just solving a 2^3 but while holding another cube, this really is a good tutorial. I has a weird situation where I solved WY, gyro'd them, then solved PP, and WY wasn't broken up, so I started to think this was normal, and that colour should be preserved in each step.... Oh well
0:38 It’s actually called Ortega
Yeah PBL is the last step of Ortega, not the name of the method
is the gyro l-r ly ry’ r-l rx2 b2 d2 lx2 or is it l-r ly ry’ r-l rx2 b2
first one
