Colorful symmetry

(Published on 29. August 2025, 18:01 by Adrian71)

This puzzle was heavily inspired by the brilliant symmetrical puzzles by Mad-Tyas

• Normal Sudoku rules apply
• German whisper: adjacent digits on a green line differ by at least 5
• Dutch whisper: adjacent digits on an orange line differ by at least 4
• Renban: digits on a pink line form a set of consecutive, non-repeating digits in any order
• Region sum: a blue line is divided into segments by box borders; the sum of the digits is the same for all segments of the line
• Digits separated by a V sum to 5. Not all V are given
• No digit is equal to the sum of its row number and its column number

Quite wonderful how this works out at the end with such restriction! I especially liked that opening there, then one spot took me embarrassingly long to spot but it's still worthwhile at the end x)

Finally found the time to solve this puzzle! I enjoyed it a lot. So I'm glad for the inspiration I could provide with my puzzles.
I have to admit I was a bit skeptical about how much the special rule can do as it affects only less than half of the grid. But you used the rule in a very beautiful way!

Thank you Mad-Tyas for solving the puzzle! I am glad I could return some of the enjoyment that I found in your puzzles. I had never before seen fully symmetrical grids, and I enjoy the concept so much, both solving and setting! I btw shared your initial skepticism, but the possibilities appeared to be surprisingly ample :)
