Pi e Prime Phi Py
(Published on 23. January 2023, 15:10 by alhobj)
My first puzzle. I think it might have a really hard break-in but I am not sure. I will be really happy for some feedback. No math knowledge is required.
Place 1-9 in each column and row.
The cage contains the 24 first digits of pi (314159265358979323846264). Each digit is orthogonal to the next digit.
There are eight lines, two of them have a single cell overlap, and there is no other overlap. On each of the lines place the first four, six or nine digits of the following:
- e (271828182)
- Golden ratio (161803398)
- Prime numbers (235711131)
- Square root of 2 (141421356)
A line can pass and use the same square twice but never its own starting cell.

Removed some tags that were incorrect

A strange puzzle in a positive way :). Some remarks to the choice of labels:
This is not a Sudoku since there are no 1-n areas besides the rows and columns. But nowadays this label is kind of legitimate if you rather want to reach the Sudoku community than the more-other-puzzle-solvers like me.
It's not META in the sense of dealing with other puzzles or referring to puzzle questions on a general level. So in my opinion this label is not correct either.
And for me the way I think here about the connected cells is not omino-like.

Thank you for the comment! This was my first puzzle, so I had no idea which tags were appropriate. I do not think I can change it from being a sudoku at this point …

I'm struggling to figure out how there can only be one overlap...! Are there supposed to be two single cell overlaps between two *pairs* of lines?

Sorry for not wording it better (and for not answering sooner). R6C7 is a cell that is clearly part of two lines. The other one has to be R3C6 or R4C6. The final sentence says that a sequence can go through a cell like R3C6 twice. As an example the order could be R4C8, R3C8, R3C7, R3C6, R4C6, R4C7, R3C6, R3C5 and R2C5. Hope that helps!

break-in was a bit tricky for me but I'm not exactly the best solver out there. quite fun puzzle and I'd love to see more!

Thank you! I am not the best solver either. I have made one other puzzle but your comment inspired me to start making another puzzle :)

Nice puzzle and quite approachable. The break in is not difficult, there is only one possible way to make the lines work.
