Equally Modular
(Published on 28. April 2023, 17:42 by yttrio)
This puzzle is a spiritual successor to my Equally Quiet and Dutch Sum series, utilizing lines that are both region sum lines as well as another line constraint.
Rules:
Normal Sudoku rules apply.
All lines are both region sum and modular lines.
-- Region sum lines: Digits along a line must sum to the same total in each region the line enters.
-- Modular lines: Each set of three consecutive digits on a line must be one each from [147], [258], and [369].
The given greater-than sign points towards the lower of two neighboring digits.
Solution code: Row 8 followed by column 9 (18 digits no spaces)

I have no idea how to break in to this. Have one digit after an hour.. I give up
-- Thanks for giving it a go! If you ever want to come back to it, you can DM me on Discord (my username is also 'yttrio' there) with your current progress, and I can give you a nudge in the right direction.

I loved it from start to finish. Got "stuck", but following the variant constraints set me free. Great puzzle!

Bravo! Excellent puzzle! I ended up with a very colorful grid, with a very satisfying flurry of placing digits at the end. Thanks!

Absolutely fabulous setting. The combination of logics and then that final disambiguation. Lovely
