Note:
The parity line is red. It alternates between odd and even.
The circles are pinkish-brown. They are odd numbers.

• Normal Sudoku rules apply.
• Digits along a red parity line must alternate between odd and even.
• Cells with a pinkish-brown circle must be odd.
• 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 diagonals pointed to by arrows outside the grid must sum to the number listed.
• 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.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.

Solution code: Enter digits in 2nd row.
