Swing Shift

(Published on 19. May 2025, 22:23 by NotSoMagnifique)

Ever since Gear Shift was such a success, I'd been wondering if the two big concepts would work in reverse. I'm happy to say that they do!

Rules:

- Normal sudoku rules apply.

- Global modularity - every 2 by 2 box of cells must contain at least one digit from each of the following sets: (1,4,7), (2,5,8) and (3,6,9).

- Entropy - any set of three consecutive digits on a peach entropy line must have a low digit (1, 2, 3), middle digit (4, 5, 6) and high digit (7,8,9). Accessibility note - there are no non-entropy lines in this puzzle.

- XV pairs - digits separated by a V sum to 5, digits separated by X sum to 10. No negative constraint.

- Ratio Kropki Dots - digits separated by a black Kropki dot have a value ratio of 2:1. No negative constraint.

This became a lot easier when I realized it is global modularity instead of global entropy. :)

This was very pretty, thank you! I do love how these two sets interact when you put them together, and you made it very beautiful in both of these puzzles!
