Very nice puzzle with some nice lightbulb moments, although I had to resort to a notepad for the ending.

Thanks for asking. Sardines and herrings is my niche.
As noted below, the list of primes is very helpful.

Thank you for this nice puzzle, Will Power! It has a really original idea. And I have to admit: I was happy to see you provided us a list of those prime numbers, so we did not have to factorize all odd numbers up to 1000. :)
@sujoyku You are welcome. Yes, I like the original idea, but I think if I had changed it into a prime number hunt that many people would have just skipped this puzzle. That would have defeated the purpose. Thanks for playing. Peace to you. -Will power

Great research and a masterful execution. Too deep to be 1-star in difficulty, even after grid wide parity coloring.
Ahh, when you do your deep-sea fishing, are you out for tuna, sea bass, salmon, swordfish, or shark? 8-) -Will Power
