What are the odds? (Parity killer/little killer)
(Published on 18. August 2023, 10:15 by sujoyku)
- Normal sudoku rules apply.
- Parity little killer: On a marked diagonal, the little killer clue indicates the value of the sum of all even or all odd digits on that diagonal. If the even digits are counted, no odd digit contributes to the sum and vice versa. Whether the even or the odd digits sum up to the indicated value has to be determined by the solver. (If there is no conflict with other rules, digits may repeat on a diagonal.)
- Parity killer cages: Digits in a cage do not repeat. The killer clue indicates the sum of all even digits or of all odd digits which are contained in that cage. If the even digits are counted, no odd digit contributes to the sum and vice versa. Whether the even or the odd digits sum up to the indicated value has to be determined by the solver.
Here you can solve the puzzle online:
Solution code: Column 2 from top to bottom (9 digits in total)

Broke it two times and needed 140 minutes overall. I enjoyed my Odyssey nonetheless because it contained some pretty cool logic
Reason for breaking it was that I missed that 4+0=4 too (could only think of 2+2=4)!
And I did not treat this puzzle like a parity puzzle at first. Once I did, the late middle to end parts became much smoother.

Thank you for your comment, tsc! I think the ambiguity of the clues can easily lead to overlooking options. I also had to be very cautious when I was test-solving myself.
I am glad that you stuck with the puzzle and eventually had an enjoyable solve.
Kind regards, sujoyku
