Spooky Division

(Published on 30. October 2024, 18:40 by sujoyku)

This puzzle has been set for Scojo’s Halloween prompt. To my knowledge, it features a new constraint which can be described as a rough region sum line, i.e. segments do not need to have equal sums, but may differ by at most 1. The total sum of each line must be the Halloween number 31. Many thanks go to gdc and the testers on the CTC discord! As always, your comments are highly appreciated. I wish you a happy Halloween and joyful solving!

- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.

- Spooky Division Lines: On each line in the grid, the digits must sum to exactly 31. Moreover, lines which are separated by box borders are split into segments whose sums may differ by at most 1.

- Inequality: The inequality sign is a "greater than" and points to the lower digit.
