Logic Masters Deutschland e.V.

Update: I'm leaving this public so people can see it for the record, and just to note the error I made.
I had thought the problem was signaling in the puzzle, but with some help from the_cogito I found this was functionally broken. The intent was that you could force 5 out of r2c8 due to loss of low digits in row 2 or column 8 due to conflicts with the disjoint set through column two and row 8. After working through it with the cogito I realized that the logic that I thought constrained column 8 was incorrect. You can still technically solve this, but with that logic being incorrect I think it devolves to bifurcation. :-/

Normal Sudoku rules apply.

• 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.
• Adjacent digits along each german whisper line must have a difference of at least 5.
• Digits must not repeat at corresponding box positions (disjoint union)
• Min/max cells must be greater than or less than their orthogonally adjacent neighbors as indicated by the symbols bordering the cell.
