RE: TIL how to almost solve a Rubik's Cube!

in #til8 years ago

My brother has several variations of these cubes.

He can solve the one you pictured in your post in 15 seconds no matter how messed up it is. I have personally seen him do it many time.

He also has one that looks like this:

Yes, he has also solved that one in front of me. Mind = Blown

Sort:  

That is amazing.... 15 seconds? Did he tell you his secret?

its actually relatively easy.... there's a specific set of three or 5 turns that if you do it enough it will eventually solve it the world record (by machine) is like half a second. A person who

There are also set patterns for turning corner pieces, which is a key move to solve it.

That's amazing... are you able to solve one?

yeah, i used to be able to do it really fast when i was a kid (probably not 15 seconds, but a minute or two).

The key is to understand how the corners and edges orient to one another. that is to say, if the top left corner has green facing back, the top right also needs to have green facing back.

One of the things that screws people up ,is they will get a side or two all the same color or mostly the same color, and think its "solved" but they actually still have pieces in the wrong place, or facing the wrong way.

The easiest way to start is to start by solving the corners for a particular color. BEcause it will give you an idea about how relative orientation comes into play.

Its not enough to just get all 4 white corner pieces on the same face

you have to get it so that the A and B pieces have the same color in positions 1 and 2, and opposite colors in positions 3 and 4.

There are 8 diff corners, each with a different combination of 3 colors, and they all have to be in a specific postion relativel to each other.

so in the pic above, if my A piece has green at position 1 and red at position 3, my corners will look like

A (red 3, green 1)
B (green 2, orange4)
C (red 5, blue 7)
D (oragne 6, blue 8)

The other 4 corners will be the ones directly below their counterparts, and theyll be exactly the same except with a yellow face.

Nope, and I tried to keep up with is hands but dude... it is just a blurr haha.

I just texted him though, he said there is a pattern to it. Once you know it it is easy.

WOAH! I also just found this:

Apparently there are even people who can solve it in under 10 seconds. O_O

That is unbelievable...

Tell him to make a quick video showing it and explaining it... would make a good post for you and it would be quite helpful! ;)

Just make sure you link it to me so I don't miss it!

He is in Alaska at the moment (dang pilots) and unable to get online or make a video haha, I should ask him to do it though. He isn't as tech sound as I am. Heck maybe I will make a video with him if he visits sometime soon. He is always away some where.

Perfect! Yea, if you get the chance just have him or you use your phone... we all the ability to be film makers right at our finger tips ;)

Dude, that's insane!

That is nuts. Wow
