Too Close For Comfort

(Published on 3. March 2024, 16:11 by Niverio)

Another ambiguity puzzle, this time with Renbans and Region Sum Lines. Enjoy!

Rules:
Sudoku: Place the digits 1-9 into each row, column and outlined 3x3 box without repeats.
Ambiguity: Each given line in the grid is either a Renban line or a Region Sum line. No line possesses both properties at the same time. Which line is which type must be deduced by the solver.

Renban Lines: A Renban line contains a set of consecutive, non-repeating digits in any order.
Region Sum Lines: Box borders divide each line into segments with the same sum.

Pretty intricate solve, but lots of cool and satisfying deductions overall! As others pointed out, I also like the way you integrated the idea of 'a line cannot be both types' into the solve :)

I really liked this! Had a smooth solve, especially after learning that lines must be either Renban or Region Sum, but not both. :)

Cool little puzzle! Definitely really really hard, but it was always easy to figure out where to look next (imo) so it wasn't too terribly frustrating.

Nice flow and great use of the relationships between the line types
