Hariyama feat. Justalilguy (Killer, Region Sums)

Hariyama

Recently Justalilguy and myself have been brainstorming an idea for a new puzzle that we want to collab on. We’ve mostly figured out a ruleset, but before we dove into setting it, I wanted to set a standard variant sudoku so that we could get a feel for each others setting style. This is the puzzle we made and we decided I would post it since my setting style ended up overwhelming the grid. Hope you enjoy!

Rules:

Normal Sudoku rules apply.

Region Sums: Box borders divide lines into segments with equal sums. Different lines may have different sums.

Killer: Digits in a cage do not repeat and sum to the indicated total. Cages marked with an “A” sum to the same total.
