Hi Twisty Puzzles fans,

Pentastick is based on an idea by David Pitcher, posted at the Twisty Puzzles Forum, and enhanced by Eitan Cher, Anthony Villaveiran and Carl Hoff. Conventional twisty puzzles have all turning axes going through a single origin. Not for this puzzle, which has two origins. Each half of the puzzle alone plays like a simplified version of the Pentagonal Prism. However, as the two halves exchange pieces, the puzzle as a whole is much harder.

Developing the mechanism was quite a challenge. I used a shells mechanism for each origin. However, as the two origins are so far apart, there was little space for the mechanism. The pieces look quite different from "conventional" twisty-puzzle pieces. Still the puzzle is quite stable. I bolted the ten centers from the inside out, which required some dexterity.

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

Enjoy!

Oskar

Really cool. My favourite puzzle from you. So can you add more than two origins to this puzzle?

That core looks amazing! Or is it plural now? Cores?

Anyway, great puzzle! The youtube video showed great turning.

Fantastic! It's amazing how fast you were able to take this from an idea to physical reality. I'm very curious as to how challenging the puzzle is to solve. I guess I'll have to buy one!

I followed the multiple origins thread from the start and I thought "What substances are these guys taking?" And here is the result. Another mechanical masterpiece Oskar! Every time you bring out another puzzle I tell myself that I must get one, but it is always hard justifying spending so much on a single puzzle, especially to the boss (that's my wife :wink: )

The core (or should I say "cores") look very interesting, great job! :D

Can this puzzle be made with the corner turns on the ends like the pictures in the original thread?
Great job! There's no difference between imagination and reality when oskar's involved! :P :D

Great looking puzzle Oskar... well done!!

Core does NOT equal Origin. This puzzle has 2 origins and a single core. Hang around a bit as I'm about to post my new puzzle idea. It has a single origin (i.e. all the turning axes going through a single point) yet it has 2 cores.

Just another classifying challenge.
Looks like a puzzle made by restricting an infinitely long puzzle.
Strange but cool!
