Recently I came in possession of a Rubik's Cube like device called the "Quad Cube", which is four 2by2by2 Rubik's cubes that share sides diagonally.

If any of you have experience with one of these, could you please tell me how to solve it?

I just looked it up and it looks quite difficult. It would be an interesting challenge but I don't know how you would solve it. Sorry, can't help you much.

I would assume you could just use basic 2x2x2 algorithms, but accounting for the conjoining cube as one corner. The middle two may take a bit more trial and error.
This really seems more of a challenge in the task of trying not to break it.

Agreed. I've seen these before and decided I didn't want them because I doubt it actually adds any complexity, only apparent complexity.

At first it looked like it may cause confusing collisions on the two inner cubes, but on further thought, it seems that it would be just like solving for 4 2x2x2 cubes.
