• 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.
