simplified version (no cosmetic lines)
Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
Region Sum: digits along each segment of the same blue sum to the same total (line segments are divided by region borders);
Renban: digits along a pink line form an unordered consecutive set of numbers;
German Whispers: along a green line, each digit must differ by at least 5 from the next.
Solution code: Row 1, left to right.

The good thing about the puzzle is that if you assumed the symmetry to have some progress in the puzzle (because there's no way to resolve it until the very end of the puzzle, and it's impossible to keep it all in your head, so you just have to) and you ended up assuming the wrong one, then you don't have to re-type the whole damn grid when the asymmetric renban finally starts doing something, you can just enter row 1 right to left into the solution code. Very thoughtful of the setter!

Very enjoyable with some interesting interactions and smart constraints built-in.
