Did anyone build this puzzle: Twisty Hollow

I built this using Livecube by grouping piece A and D into group 1 (2 linear moves), B and C into group 2 (1 rotation move, 2 linear moves). After that, position group 1 and 2 about 45 degree of each other and twist them in place in 1 rotation move. When I built it from wood, this twisting move is impossible since the puzzle is not flexible like Livecube. I tried to round the edges as much as I can. The website says 5 moves to take out the 1st piece, did anyone confirm this solution? Are there any rotation in those 5 moves?

Hi Thai

this puzzle is possible in wood without rounded edges, it is a legal turn; I made one for my collection and it works perfectly

all the best
Bernhard

I have a Livecube model right here and I don't think any flexibility of the pieces or rounded edges are needed. Is your twist the same as a rotation? I put the pieces together in the same order, and it seems to me the final mating of A/D, B/C is done using a rotation.

To disassemble, I do:
B - 2 unit linear move
C - 1 unit linear move
B&C - 1 unit linear move
B&C - rotation and move to separate

Hi Thai and George

the second one will be confusing an needs some rounded edges for the different turns

but it is a great idea

have fun
Bernhard

Hi Bernhard and George,
Thank you, I was able to see the solution now. I think when I did the Livecube, it was a bit loose, so I was able to rotate the A/D and B/C with only 1 move.

You guys on this forum are great help for newbies like myself. Yes, I did try the Twist the Night Away with Livecube. I think this one has the most rotation moves of all his cubes (I counted 7 rotation moves).

Thank you Tom, please keep them coming. Tell us what kind of coffee you drink to come up with designs like this.

For added fun ...

Try building your Twisty Hollow with a 2x1x1 piece inside. Now to take it apart you have to tilt it to shift this loose piece into the correct position.

Nice to see everyone is enjoying these two designs so much! Twist the Night Away was more of a happy accident than a "design", but Livecubes certainly helped the creative process.
