Greetings. Here's another easy one that I hope is a nice snack. As always, feedback is welcomed and encouraged, so leave a comment below with your thoughts. Thanks for playing!
- Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
- Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
- Odd/Even: Digits in gray circles are odd. Digits in gray squares are even.
- Little Killers: Numbers outside the grid give the sum of all cells along the diagonal pointed to by the arrow.
- Nonconsecutive: Orthogonally adjacent cells cannot hold consecutive digits.
- Positive Diagonal/Negative Diagonal: Digits along the positive diagonal (R9C1 to R1C9) must be unique. Digits along the negative diagonal (R1C1 to R9C9) must be unique.

This was absolutely brilliant. Steady flow from start to finish.

Man, I was distracted, but still I found this one brutal. I love negative constraints, but I just kept missing the key places to take advantage of them.
90 minutes, only averaging 1 digit every 10 minutes for the first hour. Sad trombone.

Can confirm you can get pretty far without nonconsecutive XD

The nonconsecutive rule is not in the sudokupad link! Just beware if you're solving going straight to the sudokupad link.

Took me a while to realize I missed the anti consecutive constraint in the rules.

Thanks for the response! Lovely 15-min snack, really enjoyed it!

Updated the rules to include digits not repeating along positive and negative diagonals.

Can digits repeat along the marked diagonals? I'm not seeing it mentioned in the rules.

(lgastako): thanks, I've updated the rules here and on sudokupad.
