Sudoku on:
SudokuPad
Rules:
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Fire and Water cells: There are nine Fire cells in the grid, exactly one in each row, column and marked 3x3 box and filled with a complete set of the digits 1-9. There also are nine Water cells following the same rules as the Fire Cells. It's possible for a cell to belong to both sets simultaneously. The value of Fire and Water cells is the digit in the cell multiplied with the minimum number of orthogonal steps between the Fire cell and the Water cell within the respective marked 3x3 box. If a cell is Fire and Water cell at the same time it's value is 0 cause the minimum number of orthogonal steps is 0.
Note: As the same rules apply to the set of Fire cells and the set of Water cells, it's not possible or required to decide which of the sets is Fire and which is water.
Nabner: Each value on a golden line must differ by 2 or more from each other value on the same line.
Have fun solving!
Solution code: All values in row 4 (left-to-right).

Looking forward to this already - the longest Nabner I know of before this one was https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000F3D which was an excellent 5* puzzle. And deserves a re-visit from anyone who solves this one.
