Rubik's Cube Security on point
My grandson can solve a totally scrambled cube in about 30 seconds. But 3.14 seconds? Holy crap. That shits amazing.

Speedy.
His personal backstory is interesting.

There are a humongous number of ways a Rubik’s cube can be disorganised. Some start positions will take more rotations than others to get the cube back to a standard start position. So how do they make “record time” attempts fair?

That was really impressive.

Time to reset the bar. Time starts as soon as they remove the cover and the contestant sees the cube. The planning stage is part of the total time to solve.

Then what's your theory?

I think I may have solved one in 3.13 years once.

Impressive, but I think the clock should start when the cover comes off the cube. Studying the cube and figuring out the strategy to solve it is part of the skill. The "free" study period doesn't make sense to me.

Looking at the video in Para’s OP, it appears to me that his “planning stage” time was in addition to his 3.14 second manipulation time.

Rightwire said, "time to reset the bar" prior to that statement. Makes all the difference.

Maybe a dozen years ago, I handed a cube to my son, I already scrambled it for awhile. He solved it in approx. 30 secs, right in front of me. His best time was 20 seconds. He and his friends were into this back then, he still knows how to solved it at will.

I can pull a brand new cube out of its clamshell and make it completely un-solvable (by me) in less than the time it takes to open the damn clamshell box. Do I get a prize for that?

Yeah, that was me in 1978 or 79 when it was a national fad.

I like how you guys have decided their rules are suspect. It’s their game it’s their rules. They get to look it over first. That’s part of the game. You guys don’t get to say their rules are bullshit though, you don’t even know the game. I think pickle ball, while fun, is a silly little game. I don’t get to make them change their rules though. No more Nasty Nellies or Hurry up Harry’s or whatever bs they have come up with. It’s their game their world championship. Lol

I don’t care, that shit was fast no matter what anybody thinks. (never had a Rubiks Cube but I’ve played with them before, surprised they are still around, always thought they kind of sucked as a game and no I never solved one. Ever)

I think it would take him twice as long if he had to do it one handed.

I remember the fad in 1979 or so. I learned to solve it in five minutes or so. I would get 4 sides and then had a memorized set of moves to get the 5th and 6th sides lined up. I haven't touched one in decades, it would probably take me an hour now.




I have a few SIGs.

That's what Rightwire is saying: That the time to solve should include the planning time.

He didn't really solve the cube in 3.13 seconds. He executed the solution he'd planned, after study, in 3.13 seconds.

The cover came off at the 7 second mark in the video. He picked the cube up at the 19 second mark. Somewhere around the 22 second mark he put it down.

So, in reality, it took him ±15 seconds to solve the cube.

Which is about a bazillion times faster than I could

I’d like to see what the kid could do in Steel Challenge.

I think it’s like shooting a stage. You get walk through to make your plan, but then have to execute.

It would be interesting to make them solve the cubes, with a blind start - I’ve shot some blind matches before - but it’s very different.

Good point aglifter. It is their game. If they get a walk through of the stage they get a walk through of the stage.

I’m surprised no one has commented on the fullup N95 mask kid.
