Great puzzle, but certainly more than 1*. I would have been lost without the Phistomephel Ring. Are 1* solvers expected to know about the Ring?

Very elegant but 2 stars for me, as you should know some advance techniques to solve, in my opinion.

Wonderful puzzle! The first "break in", or at least what I thought was the break in, came supper easy. Then...oh my...Just stared at the screen for what seems like an eternity. Then out of nowhere, I find the REAL break in. Geez. Almost like one of those 3D pictures from the '90s. Very satisfying solve!

Thanks for sharing. I definitely agree with other comments that this is 2*

Nice puzzle, 12:53 for me.
I'm conflicted about the 1 star rating though, because it's only easy if you know about the 'phistomel's ring', which isn't 1 star knowledge imho.

So good. Although 2 to 3 stars for that break in surely.

An awesome puzzle! Getting the breaking was super satisfying and definitely tested my notes skills. Thank you!

Just. Wow. The back and forth between the cues is quite remarkable. I did need the ring though, not sure if completely 1*

This is absolutely a brilliant puzzle! The symmetry works so well with the whisper loops on the edges. I loved the way they restrict the thermos. Another great puzzle from you!
