- Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells. One region border is given.
- Arrows indicate X-German Whispers, where the first seen digit in the respective column or diagonal is the length of a straight German Whispers Line (of length 2 or more, with adjacent digits differing by at least 5), starting from that digit.
- Every cell on an X-German Whispers line belongs to its own unique region.
- Arrows also indicate X-Regions, where the first seen digit in the respective column or diagonal is the total number of regions seen in that direction.

Thank you! Finding the regions was challenging, but after that it still was a tricky irregular Sudoku.
