Go with the tide (Equal Split Lines)
(Published on 8. March 2025, 10:53 by sujoyku)
What are Equal Split Lines about? They can be thought of as relatives of Region Sum Lines where the breaking points do not have to match region borders. An important difference is that digits inside a segment may not repeat (even if they could by normal Sudoku). I like to thank gdc, LMDemasi, Calvinball, ChinStrap, earthpuzzles and NEWS for testing. As always, your feedback is much appreciated. I wish you joyful solving!
- Normal Sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Equal Split Lines: Dots divide blue lines into sements with equal sums. Digits may not repeat inside a segment. For example, a valid Equal Split Line could read 34-7-124.
Here you can solve the puzzle online:
Solution code: Row 5 from left to right (9 digits in total)

Such a breadstick and compact puzzle! I was in awe of the end game logic.

Thank you for your comment, Voidslime! I am glad you enjoyed it. In particular, I love to hear you liked the ending. I had reworked a prior version of the puzzle to make that phase more interesting.

Wie bereits erwähnt wurde: die ESL erlauben mehr Möglichkeiten als die RSM. Das zeigt dieses herrliche Puzzle in beeindruckender Weise. Vielen Dank dafür!

Sehr gern geschehen, Franjo, vielen Dank für deinen Kommentar! Es freut mich, dass Dir das Rätsel Spaß gemacht hat. Die ESL haben nicht nur mehr Möglichkeiten, sondern auch einen kleinen Killer Sudoku-Touch aufgrund des Nicht-Wiederholen innerhalb der Segmente. Aus meiner Sicht kombinieren sie so auf magische Weise RSL- und Killer-Logik. :)
Herzliche Grüße, sujoyku

Great new rule! It felt like long arrows without single or repeated digits. Quite fun! Very fresh, Thanks!

You are much welcome, RedBarchetta, thank you for commenting! I am glad you enjoyed the Equal Split Lines. And your observation definitely has a point: Some of my inspiration for setting this came from arrow logic. From a setter's perspective, the ESL are a treasure because you can set up the geometry without restrictions by region borders.
Kind regards, sujoyku

Thanks so much for following up on Equal Split Lines! Very nice use of geometry and a fresh idea for the breakin.

Thank you for your comment, gdc! I am glad you liked the geometry and the break-in concept. I hope I get to set many more puzzles with this fun constraint.
