I am wondering if anyone else has got this far; if you have got to a stage somewhat close to that of myself, please post a reply; I am dying to know.

I can solve three layers of a 4x4 without using algorithms.

Here's a basic description of how I do that.

-I solve the first layer one piece at a time. To do this, I'll find a piece and figure out where it goes. Then, I will move that empty spot away from the first layer, move the piece into that spot, and return that spot to the first layer. When I solve a piece this way, it doesn't affect anything else in the first layer.

-I solve the next two layers at the same time; first the edges, then the centers. I solve the edges piece by piece. When I can, I will solve the edges by moving pieces out of the way, solving an edge, then moving the pieces back. This works for a while, then I have to use a different approach. I'll move as many pieces as I can out of the way and solve an edge. However, doing this unsolves a piece from the first layer. This isn't a problem because I can solve that piece just like I did for the first layer. I can do this without affecting the edges of the second and third layers.

I solve the centers piece by piece also. Like with the first layer, I move pieces out of the way, solve a piece, then put the pieces back. I never move the edges in the second and third layers when I do this.

I know that explanation was vague, but it is hard for me to describe in words.

Hope this helps.
