One-Line Miracle (Region Sum Lines, Entropy)
(Published on 30. October 2023, 09:13 by Mad-Tyas)
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Region Sum Lines: The blue line must have an equal sum N within each 3x3 box it passes through. If the line re-enters a box, each segment sums to N separately.
Entropy: Each 2x2 box in the grid has to contain a low digit (1, 2, 3), a middle digit (4, 5, 6) and a high digit (7, 8, 9).
Have fun solving!
Solution code: Row 9 (9 digits)

I thoroughly enjoy your entropy puzzles, and would LOVE a puzzle pack of these that have walkthrough solutions included for the very hard ones! Thanks, MT!

Very cute idea. I quite like the entropy ruleset. It scratches the same itch as disjoint groups, but is smoother and much much more enjoyable.

A fairly straightforward break-in and very smooth thereafter. Thanks a lot for sharing.
