Normal sudoku rules apply.

Standard rules for renban, nabner, German whispers, and region sum lines apply. [The color palette used here was designed by Sandra to be more colorblind friendly. Please let me know if it helps! Color descriptions are at the link.]

There are no negative constraints of any kind.

Renban Lines: The purple line in the grid is a Renban line. Digits on a renban form a set of non-repeating, consecutive digits in any order.

Nabner Lines: Digits do not repeat along gold nabner lines. Additionally, no pair of digits anywhere on a nabner line can be consecutive.

German Whispers: Along green lines, adjacent digits must differ by at least 5.

Region Sum Lines: Blue lines in the grid are Region Sum Lines. The sum of digits on the line is the same within each box.
