Normal Sudoku rules apply. Green lines are BOTH German Whispers and Region Sum lines: Adjacent digits along lines must differ by at least 5, and digits along each line must have the same sum in each region entered by the line.

Very nice! The break-in is 2-star, but once you get the hang of the combined whispers/region sum lines then it flows smoothly from there.
