Is the Rubik's Revolution cool?

[qqwref]

I guess the Revolution part of it is that the cube CAN'T be messed up? I don't really see how this is much of a revolution. It's like making a set of "Bowling Revolution" brand bowling pins which are bolted to the floor and thus can't be knocked over. Sort of defeats the point IMO.

Shellie: I think one or two people have done 3, but I'm not certain who.

it is a game not a puzzle. I guess if you are kid it can be fun....for a few hours

 

[Unknown.soul]

For kicks, try playing Lightspeed BLD. I think the WR is 2, unless someone's gotten 3.

Heh, I'll have to try that

It's a Simon game jammed into a non-functional Rubik's cube to cash in on the Rubik's name.

Wow Shelley, that's an interesting game from a math standpoint. I get that the expected value for the number of turns you will last is 1/5 of a turn until your first failure (until you press a wrong button).

I treated it as a sort of geometric distribution where you are interested in the number of successes before the first failure. Let p = probability of pressing the correct button on a given turn, which is 1/6 here.

So for the expected value I did:
sum[i goes from 0 to infinity: i*p^i*(1-p)] = p/(1-p) or 1/5 tries for the Revolution.

Actually, because a color never lights up twice in a row, it's only 1/6 on the first turn and 1/5 on subsequent turns. Also anecdotal evidence suggests the first turn is more often than not a certain color (was it blue? this was discovered about a year ago when we first invented the game and I forget which color it is). I don't own a Rubik's Revolution and I haven't tested it rigorously though, so don't take my word for that.

Ack, should have thought of that. Revised expected value below:

let p = probability of success on the first guess

let p/(1-p) = probability of success on all subsequent guesses after the first guess

sum[i goes from 0 to infinity: i * p * (p/(1-p))^(i-1) * (1-2p)/(1-p)]
p*(1-2p)/(1-p) * sum[i goes from 1 to infinity: i*(p/(1-p))^(i-1)]
p*(1-2p)/(1-p) * 1/[1 - p/(1-p)]^2
p*(1-p)/(1-2p)

Or for the revolution that gives an expected number of tries at 5/24 or approximately 0.21 successes before the first failure.

--edit--
this of course assumes all colors are equally likely at all times, which is not the case on the real revolution it seems. Also check out this thread for more shortcuts the revolution took that make it not match up to the expected theory for the game. http://www.speedsolving.com/forum/showthread.php?t=2343

code cracker is fun, it's the most puzzle-like
but I don't like the revolution, not rubik's enough to be called rubik's

I am a strong believer that the Rubik's Revolution is the worst thing to happen to the world since me.

It shouldn't be called a "Rubik's" Revolution, since it really has nothing to with cubing other than the fact that it's in the shape of a cube and has colored stickers.

It's a Simon game jammed into a non-functional Rubik's cube to cash in on the Rubik's name.

Whilst there is a strong association between the Rubik's brand name and cubing (yes, I said that on purpose - please don't reply with "No sh*t Sherlock!"), I can't imagine that there is anything in the business plans of the companies that have licensed the Rubik's name that states they should remain somehow loyal to cube enthusiasts rather than just maximise revenue.

Hell, I don't even like Rubik's brand cubes!

Is the Rubik's Revolution cool?

it's cool when ur playing it with some people at 3 in the night....

 

[Sebastien]

I got mine as Prize at the Dutch Nationals.

It's quite funny but first of all because it speaks Dutch which sounds funny and which I don't understand

 

[Erik]

Sebastien mine is german xD I don't mind it being german though... if you want we can trade

I have one too. It's only half Dutch though:

Blauw charged! Rood charged! Geel charged!

 

[Erik]

Haha that's SO rubbish xD

 

[shelley]

Does anyone have a video of the Pochmann Method for doing the Rubik's Revolution?

 

[Swordsman Kirby]

Arnaud just handed me a Revolution at Nationals this year. Who could refuse?

Haha, i'm in the same situation. Mine is Belgian .
