Great puzzle. Found the beginning easier than the top cage. Thx for this.

Very clever solve! I seem to be backwards to other solvers however - I actually found the initial break in difficult to unambiguate but from then on it was flowing nicely with lots of logic.

Great puzzle! I really liked the logic involving the killer cage.

Very nice puzzle. I had to make a pi snake detour when I came to the ...85356... due to a faulty brain, but it was all good after that. Enjoyable and fun.

A very nice pi puzzle. The pi snake was pretty smooth sailing for me, but as nunc said, the killer cage had me scratching my head for a little while!

Really great puzzle and logic throughout the solve. The pi snake within the fog really made for a fun time!

Thank you very much! I loved it. All went quite well, until I got to the killer cage, which gave me a bit of a headache for a moment. But in the end it all gave up. Very nice idea and setting.

That was really enjoyable, well done! During the first lockdown in March 2020, I memorised Pi to 1,000 digits (for want of something better to do), and have for a while toyed with the idea of including Pi in a sudoku puzzle. Now I don't have to!

Very well constructed, and fun to follow! Finding the Pi Snake was brilliant and satisfying. Thanks!
