Primability

(Published on 12. August 2022, 12:10 by Jabamaca)

Description:

This puzzle was inspired by Empty Grid by Jodawo, the Prime Number portion of it. I have made a conjecture about a digit's primability and its property placement-wise in 2-digit number positioning in a Box in Sudoku. Details on the conjecture are under spoilers below.

Rules:

  • Normal Sudoku rules apply.
  • Digits may NOT repeat on the main diagonals.
  • 2-Digit numbers are read left-to-right or downwards.
  • For each box in Yellow, each digit must contribute to at least one 2-Digit Prime Number contained within the box.
  • For the box in Blue, each digit must contribute to at least one 2-Digit NON-Prime Number contained within the box.
