This sudoku features coordinate arrows, a new variant that was created in a conversation between me and Piatato. Piatato also made a puzzle using this new constraint and it features quite amazing logic. I strongly recommend solving it if you haven’t already. It can be found here: Coordinate Arrows by Piatato
Normal Sudoku Rules Apply.
Coordinate Arrows: Digits along an arrow sum to digit in the circle. The digits along the arrow give the location of the arrow’s circle, and no two arrows can indicate the same exact circle. The first cell along the arrow gives the row that the circle is in and the arrow tip gives the column that the circle is in. For example, an arrow -1-4-> would put a 5 in row 1, column 4.
Inequalities point to the smaller digit of the domino the inequality covers.

Solution code: Row 9, followed by Column 9.

Very fun and impressive puzzle. Utterly incredible logic all the way through. Rather tricky at times, especially in the mid-solve for me, but very smooth.

Wow. Jaw-dropping geometry and interactions, while still remaining kind of smooth, thanks for setting this ! And also thanks for co-creating the CA ruleset, every single puzzle with it that I have solved is a masterpiece, and in my favorites !

This was beautiful. Once I was able to finally break in it flew by.

For this was the first coodinate arrow puzzle I solved, it took some time to get familiar with the logic behind. Though it was difficult, I always had an idea for the next step. Thanks!

Extremely satisfying solve path, I'm stunned by the beauty of this puzzle. Figuring out the placement of 9s was the toughest part for me, but it was clever nontheless.

I can see why this one is held into such high regards (and just you as a setter for that matter :-) The geometry is insane in this puzzle, but not just that, there’s layering in there that reminded me of inception haha
And I sure am glad I solved it very shortly after the original CA, cause even with all that logic still fresh in my mind and the best possible start, it was still really hard and I’m afraid I stepped on a few mines before I finally pulled through XD

I’m happy to see you had a fun experience with this! I’m flattered that you think I’m highly regarded as a setter. I don’t often agree but this still made my day. Thank you very much!

Piatato's Coordinate Arrows was already one of my favourite puzzles so I had high expectations attempting this one, and I experienced again all the joy of solving it.
It was a bit tougher, especially the post-break-in part for me, but every step was so utterly satisfyingly clever that each bit of progress was absolutely thrilling.
A real shame that it got so few solves, but I'm glad my solve triggered the rating at least !
Thanks Aaronymous, this one truly took part in me having a good day :-)
**I just noticed that I forgot to respond to your comment! First of all, thank you for solving and rating the puzzle. Seeing the rating is pretty gratifying after all this time. Secondly, when I first read your comment, it was during a time when I was feeling quite down, and your comment lifted my mood. I’d say that your comment made my day like you say mine made yours!
As you’ve noticed, I’ve been solving your irregular sudoku trilogy as a thank you, and the two I have solved so far have been really fun and clever. I’m certainly excited to see what you make in the future! :)

Beautifully constructed! This one went relatively smoothly for me, and the logic path was extremely clean.
**I'm glad you had a good time with the puzzle! :)

Incredible puzzle, real gem, but very very tough (at least for me personally).
**Thank you for solving and for your kind feedback!

Magnificent puzzle! I love the geometry in this one. No idea how you even came up with such incredible logic. :D
**Thanks! Your puzzle is better, so don't ask me how I came up with this! :P
