Hi Twisty Puzzles fans,

Jumble Rock is a jumbling twisty puzzle with an unusual geometry. Can you tell what it is?

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.
Read more at the Shapeways Forum.
Check out the photos below.

Enjoy!

Oskar

If you mean the geometry with "it" I don't think you gave us much of a riddle this time. There were better ones.

You gave it away in the title. It's that of some rock.

Hey Oskar (and forum),

Responses seem to have ceased without Oskar's question being answered. From what is said in the video it seems that the geometry of the puzzle is a mystery. However, for the purposes of the TP museum it would be very helpful to know the name or at least some information about the construction of the solid that this puzzle is based on. Can anyone shed some light onto this?

If the answer is indeed unknown or just a "rock", well that's fine too. :wink:

Chandler

Looks like somebody has cut two dodecahedra in different places, and joined two different halves together to make a hybrid.

Amazing Oskar! I have no idea what the shape is called, but I would love to know more about the process you use to find such unusual jumbling shapes.

The process was similar to finding Fairly Twisted. Take some triangles, squares, pentagons, ..., join those at some edges and create a shape whose vertices have all the same distance to the origin. For example, Fairly Twisted has a skeleton of one pentagon, one square and two triangles. The vertices of the skeleton are the faces of the resulting jumbling shape.

That's some great info, thanks.

Incorrect! :-)

Technically I'm correct, because that is in fact what it looks like (at least to me!), but I take your point. ;-)
