The Rules:
- [Sudoku] Normal sudoku rules apply.
- [Three-Color Battenburg] Color the grid three colors such that all 1's, 4's, and 7's are one color, 2's, 5's, 8's another color, and 3's 6's and 9's are a third color. **All** instances where a pair of colors forms a checkerboard pattern are shown as checkerboard markings.
- [Little Killer] The sums of the digits along each marked diagonal must be deduced. They are all equal, except for one which is off-by-one.
The Puzzle:
Solution code: The digits from left to right in the row containing the more common little killer sum as a two-digit number read left-to-right. (9 digits)

Lovely puzzle. Even the solution code needs a bit of scanning on the colour palette!! Thanks, @ RockyRoer :).

much more straightforward and nowhere near as difficult as i first thought from the ratings / puzzle description, but still very rewarding and fun (and i still got the chance to tackle a difficult puzzle by trying to parse the solution code description, which took me only slightly less time than actually solving the puzzle lol)

Very nice. Don't think this rates beyond 3* though

Thought I hit avwall 2/3rds of the way but then the killers kicked in for me. Brilliant. Thanks!

Good puzzle! Even the solution code takes me some time (because of my bad english). I wonder if it is necessary though.

No numbers, just a few weird symbols as givens. This is what you should expect from RR. And a somewhat new ruleset, too. I love this stuff! Thank you very much for creating and sharing another wonderful puzzle.

I'm always a bit intimidated by your puzzles, but whenever I manage to solve one (and I succeeded with this :-), it is very satisfying. Thank you very much for sharing it.
