Strawberry Fields
(Published on 18. April 2023, 02:31 by cristophermoore)
Each pink cell either indexes the 5 in its row or in its column. That is, it either equals the row of the 5 in its column, or the column of the 5 in its row. For instance, if r3c6 is a 7, then either r7c6 or r3c7 is a 5.
Fives are antiknights: no two 5s can be a knight's move apart.
Cells containing a gray circle must be odd. A white dot indicates a consecutive pair of digits.
Feedback is very welcome. Thanks to JeffWajes/Thousand Sheep, Dia, and SimplePurpleFrog for testing!
Solution code: row 7 followed by column 7

I agree with Tamuha that there is so much nuance in this puzzle's rules in this grid. I felt like a mathematician developing lemmas and then applying them iteratively to make more and more heavy constraints until suddenly everything fell into place. Gorgeous!

This puzzle has beautiful logic, some quite complex interactions.
It was a lot of fun to solve.

Nice puzzling puzzle. The ruleset is more challenging than it appears a first or even second glance. Thanks for the tasty strawberries!

Really nice ruleset. It took me a while until I figuted out every nouance of the rules and what it means in your setting.
I had a great time with the puzzle. Thank you very much!

Amazing ruleset. I really liked!

To pekerkp, he meant r3c6

example clarified

I don't understand the example. r4c6 is not a pink cell, so why does it index anything?
[Cris] that's a reasonable question :-) I changed the example to r3c6.

Hey I'm having a lot of trouble solving this puzzle. I keep running into a spot where there is nowhere for the 5's to go. I'm probably making a mistake in logic bc I am a beginner but I was wondering if you could confirm to me there isn't an error in the puzzle setting
[Cris] I promise it's solvable... feel free to email me at moore@santafe.edu if you want to show me where you got stuck

A very clever ruleset, and lots of fun logic throughout. Great puzzle!
