It literally makes my brain hurt which is amazing since the brain has no pain receptors.

Only way I solved it as a kid was taking the stickers off.

I decided to learn how to solve these a few years back. It's quite possible to solve all but one side with deduction and figurin', but to get that final side it's a zillion times quicker and easier to solve if you memorize a handful of algorithms.

The Google version is impossible, though.  They didn't really give you the best tools to manipulate the cube.

I can't solve them, but one of my sons can. It takes a lot of planning ahead.

How can you not solve only one side? If the rest of the sides are all solved (i.e., one color), than shouldn't the last side also be one color?

I simplified poorly.  One of the most common solving methods is to think of the cube as 3 layers.  You can get one layer right easy peasy, then the second layer with a bit of reasoning.  The 3rd layer can be solved quickly and easily if you memorize a handful of algorithms.

This method is pretty much the same as what I learned.

  • Get a plus sign on one side with the colors in the right order
  • Get the corners of that same side correct, and at the same time do the blocks in the middle layer just above them

That's all there is to it for the first two layers.  Then for the last layer:
  • Get the edges aligned (6 move algorithm, and a 2nd slightly different variation)
  • Get the corners in the right places, though not necessarily oriented correctly (8 move algorithm)
  • Get the corners oriented correctly (8 move algorithm)
  • Get the edges in the right place (~7-8 move algorithm, but this one's logical and super easy to memorize the motion)
.
That's all there is to it!  Faster speedsolving methods generally have you memorize more algorithms so you can do more of that last layer stuff in a single step.  But with just the above, which really aren't that hard to memorize, I can solve a cube in about a minute or two, which feels wizardy enough on its own.

My brother-in-law looked that method up (I think) and can solve any cube in minutes.  I've never been that good and haven't looked up strategies like this.  Figure that it's cheating if you have to look.

I studied the solution in college and used to be able to do it pretty quickly, but I've forgotten how over the years. I can still get two layers pretty easily, but I don't remember the final patterns any more. I really should work on it again...

In middle school I was able to do it in under a minute, but I've long since forgotten the patterns.

Count me in as one of those people who haven't got a clue how to solve those things.

Are we not allowed to say the "R" word here? The opening link no longer helps with what "it" is any longer.

I noticed that too. We can't use the "R" word?

This.  I haven't touched one since high school, but I think muscle memory would get me through it.  Not sure though...
