Prime Binairo
(Published on 10. November 2021, 02:16 by mathpesto)
I've really enjoyed solving binairo and binairo-ish puzzles lately, so I finally got around to constructing something inspired by it. Comments and ratings are much appreciated. Hope you enjoy!
Rules:
Normal sudoku rules apply.
Binairo-ish rules apply:
No more than two prime digits may be adjacent in a row or column.
No more than two non-prime digits may be adjacent in a row or column.
Killer-ish rules apply:
Digits may not repeat within a cage.
Digits within a cage are either all prime or all non-prime.
Cages comprised of prime digits have a non-prime sum.
Cages comprised of non-prime digits have a prime sum.
(Note: 1 is non-prime)
Puzzle:
Solution code: Enter row 2 then column 8 (18 digits, no spaces)

@S4F, I haven't been able to find a second possible solution. Can you share more, perhaps as a hidden comment? Thanks! -MathPesto

That was a lot of fun. Cool ruleset. Thanks for the puzzle!
For me it was special cause I could discover some parallels in the logic to a puzzle (https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000795) I set a while ago, although the ruleset differs significantly.
