Assuming they made this fair and there aren't any identical small blocks, this is just the same as a regular cube.  From a solved cube you can tell which numbers belong to which face and just relabel them with colors if you want.  Which face a particular '1' belongs to is determined by the other numbers on its block.  The three different 5's in the center squares can't be distinguished this way, but since you can't change the orientation of the middle squares in relationship to each other anyway, you'll still be able to tell which 5 is which from the location of the other 3 center squares.

If there are identical corner/edge blocks, then either it's easier than a normal cube because you have more freedom or it's impossible to solve without guessing or somehow marking which block is which.  Going off what's on wikipedia, I believe it will be easier if the number of duplicate pairs of corners and the number of duplicate pairs of edges are both even or both odd, and harder otherwise.

/firefox is trying to get me to spell 'colors' as 'colours' and 'center' as 'centre', how the crap did my language get set to Limey?

Is this a Sudoku cube?  Because I was given one of this as a Christmas present about four years ago.

/doesn't do Sudoku, doesn't do Rubik's, gave the friend a WTF look behind his back

Why can't it be both?

And is better.

Or is inclusive to mathematicians unless you specify that you want it to be the exclusive or.

I think this generates the Lament Configuration.

In other words, unless you've memorized these numberical formations, solving this puzzle will be all but impossible for anyone other than practising mathematicians.

Anyone else dislike this phrasing? Practicing mathematicians are those who are likeliest to have memorized these series of numbers, thus simply saying this will be impossible to solve without having them memorized is enough; mathematicians would not have some means to simply divine the configuration without knowledge of the series themselves...

Pah. Child's play. I'm waiting for a version based on Rubik's Revenge.

There are no different colors, yet.  They need one which has LED lights which change colors based on the way the numbers are aligned if you really want something interesting.

There are also 5x5 and a non-rubix 6x6 and 7x7.    Plus open cubes and other mind blowing stuff.

Meh, wake me when they come out with a non-euclidean Rubik's Cube.

If I know anything about mathematicians, it's that they like to spend their free time solving problems that are only hard because they are intentionally obfuscated.

Mister Peejay: Is this a Sudoku cube?


My first thought.

/I do sudoku, but Rubiks have always stumped me
//may try again now that I know a trick. . .

Mobius cube!

/dunno if that qualifies as non-euclidean, but could get interesting. . .

They swapped numbers for colours so you have to be a mathematician to solve it. What the derp?

/Bet I can solve it in under five minutes.

I had one of those.  I thought it was Rubik's Revenge.

So what is a Rubik's Revenge?  Was that the funny spiky thing that sucked because it would always bind up on itself?

Revenge is the 4x4x4 version of Rubik's Cube. I'm not sure what the spiky thing you're thinking of is, though.

This a-hole of a puzzle:  http://en.wikipedia.org/wiki/Alexander%27s_Star

Its two superpowers were the ability to bind up and the ability to piss me off.

Yes, because "numberical".
