Solve with Sudokupad
After you have solved it, click here here to see the picture without numbers.

I have made the solution code the last column. This is because once you’ve climbed the stairs to the top, the rest of the Sudoku is trivial. You don’t have to finish it. I did this because I want the puzzle to end on a high. You’ll see what I mean when you get there. :)

• Normal Sudoku rules apply.
• Adjacent digits along a green German whisper line must have a difference of at least 5.
• Digits along a dark orange Dutch line must have a difference of at least 4.
• Digits along a light orange parity line must alternate between odd and even.
• Digits along a magenta renban form a set of consecutive non-repeating digits in any order.
• A black dot between cells indicates cell values with a 2:1 ratio.
• A white dot between cells indicates cells with consecutive values.
• Not all dots are shown.
• An X between two cells means they add up to 10.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
