First of all when I talk about a big cube I'm reffering to a
cube bigger than a 5x5x5. I've heard that a 6x6x6 is the largest cube that
could be made with the current design used for building cubes, but that it is
also possible to overcome. The only way that I know of to use a big cube is
on a computer, whether it be through a java applet or some other programming
language. Below you'll find all the basic facts I've found about big cubes
from my experience.
The most important thing about these big cubes, which is in fact the very first thing you look at when solving them, is if it is odd or
even. The 4x4x4 and 5x5x5 help illustrate this. The 4x4x4, as with any other even numbered cube, has no set center piece. Instead of one center piece an
even cube has a group of four center pieces, like a square cut into fourths. An odd cube has one set center piece in the very middle, which means the
centers can't be moved around in relation to each other, like on an even cube. Odd cubes are also easier to solve as they eliminate certain positions
only possible on even cubes.
Go back to the top How difficult is it to solve a big cube?
To put it in simple terms to solve a big cube is EASY. Surprisingly these larger cubes, despite their look are not
very hard. I have been doing Rubik's Puzzles for about three years now and I
think I can safely say once you get past the "stepping stone" 4x4x4 and 5x5x5
cubes big cubes don't take much more thought to learn to solve. From the
first time I tried a 6x6x6 I must have solved maybe 5 or 6 6x6x6 and 7x7x7
cubes and then one 11x11x11 and I had refined my solution to work with
any cube. Now I say that big cubes are easy but maybe I should clear
something up. Big cubes are easy when compared to the 4x4x4 and 5x5x5. It
took me, I believe, four months to be able to figure out a solution to the
5x5x5 that worked every time. Then after that I figured out the 4x4x4, which
might have taken a week or two. After I had gotten over this "stepping stone"
as you can say then big cubes came very easily, as the 4x4x4 and 5x5x5
prepare you for almost everything that comes up. There are a few things that
come up that you wouldn't expect but if you've gotten past the 4x4x4 and
5x5x5 then they won't stop you for very long.
*If you alter your Rubik's
Cube time in the formula you can find more exact times for the larger cubes.
If you're just trying a big cube for the first time then pick your worst
rubik's cube time (ex. Your time when everything seems to go wrong). The
reason for this is because the first time you try a big cube, everything goes
wrong, you mess up a lot, you have to stop to find pieces a lot. If you're
used to using big cubes then use one of your fastest rubik's cube times to
get a closer estimate of how fast you will solve a big cube. This also lets
you find a pretty good estimate of the fastest possible time you could solve
a big cube. For example using my fastest rubik's cube time, 17 seconds, I
know that the fastest I could do the 11x11x11 cube is 41 minutes 54.11
seconds. This can help to show how much room for improvement you
have.
