The Glue That Oils the Wheels (killer, region sum)
(Published on 21. August 2026, 17:03 by Chilly)
Following on from a series of region sum lines puzzles I've been working on, here's an older one that I made a while back. It's named after my ex boss, who was incredibly resistant to change. It's pretty straightforward - please enjoy.
The Rules:
- Normal Sudoku rules apply.
- Region sum lines: box borders divide the blue lines into segments, and the digits on each segment must have the same sum. Different lines may have different sums.
- Killer cages: digits in a cage must sum to the total given it its top left corner. Digits may not repeat in a cage.
