I have really been enjoying working through some of juggler's puzzle series that uses silent-little-killers, the most recent being Curiosity.

I wanted to explore another internal little-killer clue-type, and after getting some great feedback from juggler (thanks!) have landed on this.

I am hoping to put together some puzzles that include things like doublers, halvers, copycats and the like, so I have tried to make the ruleset applicable in those types of puzzles without having to do a significant rewrite each time.

I hope you enjoy!

RULES:

• Normal sudoku rules apply.

• Little Killer Quads: The sum of digits along an indicated diagonal (arrow) must appear in at least one of the remaining 3 cells surrounding the circle from which the arrow originates. The total value of this sum must be contained within a single cell. If a circle has more than one arrow, each diagonal could be a unique sum or the same sum.
