Introduction to Sum lines
(Published on 12. October 2024, 10:41 by Twan2797)
I have made this puzzle as an introduction for the line as an approachable sudoku without too much calculating. Please let me know in the comments what you think about this line and this puzzle.
Rules:
Normal Sudoku rules apply.
Renban: Digits on the pink line form a set of non-repeating consecutive digits in any order.
Sum lines: Digits on the red line are a sum or subtraction of the previous two digits. Digits may repeat on a line if allowed by other rules (e.g. 1,3,4,1 is valid, but also 7,3,4,1).

Solution code: Column 6, top to bottom (9 digits)

Wow. Fascinating rule set. Stunned I’m the first solve, but it did take me some time and some scratch paper to work out all the possibilities. Sadly, in retrospect, I could have been much more efficient if I had handled the branches better! Thanks!
