Every Pea, Every Screw (with sujoyku)
(Published on 30. May 2025, 15:44 by SamuPiano)
sujoyku and I have teamed up once again! This time we have combined our beloved split pea lines with a twist on Gerhard1963's region sum screws.
The title is a reference to the Placebo song "Every Me, Every You." We hope you enjoy it!
Rules:
Sudoku:
Normal sudoku rules apply, i.e. each row, column, and 3x3 region has to contain the digits from 1 to 9 once each.
Region Sum Screws (variant):
Box borders divide the blue lines into segments. Segments with a black screw between them have a n:1 ratio, i.e. one of the segments sums to n times the other, where n is an integer (to be determined by the solver). No two black screws may have identical ratios.
Split Pea Lines:
Digits on a line between two circles sum to a two-digit number written using the digits in the circles. For example, 3_346_1 could be a valid split pea line, as 3+4+6=13, which is 1 concatenated with 3.

What a joy! I despaired at first, but with some perseverance (and a calculator), everything unfolded so fairly and smoothly. Thank you both so much!

Really nice use of the constraint and global disjoint condition here. Every deduction felt so intentional and tightly set.
