-Three of the puzzle pieces must contain 4 "cubes"
-Three of the puzzle pieces must contain 5 "cubes"
-All puzzle pieces must not have 2x2 blocks contained in them
-All puzzle pieces must be 2-dimensional (that is with a maximum height of 1 cube in a single direction)
These restricions led to the creation of the Uni-Cube Black. The Black puzzle has 2 solutions, both only slight variations of each other (and an additional 2-dimensional solution as well).
After completing the Black Uni-Cube, I decided to make a white counterpart that had all of the same restrictions, except that all of the pieces must NOT be 2-dimensional. The White Uni-Cube was much simpler to design and build, and has a few more solutions than the Black Uni-Cube.
I am very proud of the two Uni-Cubes, and they have gone through extensive re-designing (especially the black one), so any feedback would be greatly appreciated. .
The goal is to fit the pieces into the 6x6x6 cavity inside the 8x8x8 box.
The orientation of the smooth tiles were designed to aid in finding a solution. Good luck!
