Primality Party
(Published on 12. March 2021, 15:44 by abed hawila)
This variant is inspired by @glum_hippo parity party variant.
Rules:
Numbers along the edge are 'Primality Party' clues. They indicate the sum of all digits up to and including either the first prime or the first non-prime digit. One-digit clues could just equal the first seen digit (i.e., the sum of zero primes and a non-prime and vice versa).
Example:
This is the link for the 6x6 if you want to try before the main puzzle: f-puzzle link for the 6x6
f-puzzle link for the main puzzle
Enjoy!
Solution code: Row 4 Row 6 (18 digits, no spaces or commas)

Wow that really was a hard (yet beautiful) one for me; it took me like forever to spot which clues should be the best places to start but once I got so, it's a whole journey full of delightful arithmetic works x)

I was finally able to solve that puzzle.
It deserves more solves, very nice variant.

Interesting variant! Bit tricky in the beginning, I had to backtrack after making a mistake in row 9, but that revealed that the opposite case led to the solution. Working it out after that was a lot of fun.

I don't think I'll ever develop an intuition for these patterns, but that doesn't make it any less fun! Very nice construction.
