Lucky (Symmetrical Palindromic Arrows)
(Published on 26. July 2022, 23:55 by AnalyticalNinja )
Normal sudoku rules apply.
Digits along an arrow sum to the digit in the attached circle, two digit circles read from left to right or top to bottom.
All arrows (including the attached circles) are palindromes and read the same from either direction.
Cells separated by a white dot contain digits with a difference of 3.

The way this all unfolded from the tiniest kernel of asymmetry was just magic. A wonderful puzzle!
- Thanks so much Ennead! I'm really glad you appreciated this construction so much, it was no easy task to find.

The pre-math required is worth it for this beauty of puzzle. :)
- Thank you so much! I'm so glad you found the pre-math required to be sufficiently rewarded by the rest of the puzzle! ^_^

Completely absurd that a puzzle this symmetrical has a unique solution. Really great stuff
- Thanks so much! I was really happy that I found a way to have a fully rotationally symmetrical grid, so I'm glad you appreciated it too! :)

someone pass this on to ctc, im too much of an amoeba to solve it but i want to see a solve
- Well you can always send a recommendation email to CTC yourself! ;) Also this one definitely is a bit tricky if you're unfamiliar with the math involved with palindromic arrows, I don't blame you at all for not knowing where to start!
