What sort of skills/ brain processing powers enable one to solve the Rubiks cube quickly and are they useful in daily home and work life?
For the record, I could only do 1 face and that took several minutes.
Not really skills, it learning about 4 or 5 algorithms, once you know those and which to use in order you'll do it every time in about the same time, me I can do it in about 2 minutes which I would say is the norm for most who know how to solve it.For the record, I could only do 1 face and that took several minutes.
19 seconds, but it was a fluke, as it just fell right from the middle row.
In my teenage years 30+ years ago I could do it under 2 mins without fail.
Whenever they make a resurgence every few years I find I can still do them as long as I don't think about it. My hands just 'remember' how to do it.

If someone is completing the Rubiks cube in a matter of seconds (same colour on every face), is the cube in a favourable random set up to permit this?
Are there some permutations which would prevent a quick solution or even be unsolvable?
My average is 20 seconds - that's considered rather slow these days as there quite a number of people averaging down around 10 seconds. Current record is 5.55 seconds iirc.Are there some permutations which would prevent a quick solution or even be unsolvable?
Some permutations are mariginally harder depending on which method you use but it makes less than a couple of seconds difference usually.

fooking hell - how the F do you do that Some permutations are mariginally harder depending on which method you use but it makes less than a couple of seconds difference usually.
,obviously not the way I do, top row, middle row, bottom row.Edited by sparkyhx on Monday 3rd November 16:24

I use the ZZF2L method for the first 2 layers. It's pretty quick and also has the bonus of reducing the number of cases you come across for the last layer. I then use OLL (orientate last layer) to put the last layer pieces I the right place but not the right way up and then PLL (Permute last layer) to finish up. ,obviously not the way I do, top row, middle row, bottom row.Edited by sparkyhx on Monday 3rd November 16:24
OLL is 57 algorithms although I know approx half and you don't see most cases anyway, PLL is 21 algorithms and I know all of them.
FWIW It takes me approx 90 seconds to do the cube with the layer by layer method.
I wondered what that thing was that the wife picked up from the charity shop a few months ago; she was looking for toys for the grandson and amongst many other things she came home with this clear sphere with coloured balls in, she thought he may like the colours, he was only 6m old at the time.
The grandson is a year old now and still hasn't managed to solve it!!
