Introduction to Sum lines

(Published on 12. October 2024, 10:41 by Twan2797)

I feel like it is time to try out a new line, whereas this line is to my knowledge not completely new, I do feel it has not been represented excessively and it allows for plentiful new deductions.

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).

die Regeln sind etwas unklar
sind z.B. R2C3 und R2C5 die previous Felder für R3C4 und welche sind es für R4C5

ebenso unklar ist das für R5C7

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!
