Puzzlemasters – if you’ve already figured out how to solve Rubik’s cube in under 9 seconds flat, you’re probably in need of a new challenge. Well here something that should keep you busy for at least 30 seconds. These insane Rubik’s cube derivations combine the power of multiple cubes to provide a really dastardly puzzle challenge.

Shown above is the mother of all puzzles, a conjoined sextuplet of cubes to keep you on your toes. But if you’re more of a puzzle amateur like me, I think the triple should provide ample challenge.

After you finish that, you can graduate on to the quadruplet version.

And then the quintuplet. It’s all a bit like Mr. and Mrs. Rubik took too many fertility drugs.

If you’re ready to have your mind bent, you can find all four versions of these conjoined Rubik’s cubes over at DealExtreme.
