Ulticube

Just thinking about the solution a little...

Spoiler

Each piece must be on all 6 faces and appears exactly 3 times in the cube, so using some basic math the possibilities must be:
- two corners, one middle center (one color)
- one corner, one edge, one center (six colors)
- three edges (two colors)

One possible solution:

041  638  275
527  104  863
386  752  410

EDIT: Haha, this looks suspiciously like Stefan's solution

I think what other people meant when they said they had used these before were something like this:

Edit: Actually, this seems even closer to the same:

So it seems like the only thing unique about Ulticube is the set of rules for the seven puzzles that you need to solve.

In Denmark (and UK I guess from the URL) we have what is called Centicubes. (referring to Mikes post not Ulticube)

Used in school in all classes up to 10th grade basicly.

(Centicubes because they are one centimeter on each side)
