This sudoku has been created for the qualification for the german sudoku championship 2025. It has not been used, because it was seen as too difficult.
Rules: Standard Sudoku rules apply. For each line, digits on the line have an equal sum within each box it passes through. This sum can be different for different lines.
Solution code: First row, followed by row 6 (left to right).
