UMBRAMETER: The Speed of Dark
- Kropki dots
- Whisper lines
- Little killers
- Minimum and maximum cells
The brief
Normal Sudoku rules apply. KROPKI PAIRS- Numbers with a black dot between them (meter needle) are in a ratio of 2:1. Numbers with a white dot between them are consecutive. Not all possible dots are shown. DUTCH WHISPERS(+)- Numbers on red lines (meter body) are at least 4 apart from their neighbors on the line. ALL NUMBERS on red lines are UNIQUE TO THAT LINE. No lines have any numbers in common with the other two lines. MIN/MAX- Cells with > (Greater than) pointing outward are greater than all adjacent cells. Cells with < (Less than) pointing inward are less than all adjacent cells. LITTLE KILLER- Numbers outside the grid are the sum of the indicated diagonal.
