2. Anti-Knight Rule
Cells a knight’s move apart (as in chess) may not contain the same digit.
3. Black Kropki Dots
A black dot between two cells indicates the digits are in a 1:2 ratio. Not all possible black dots are given.
4. White Kropki Dots
A white dot between two cells indicates the digits are consecutive. Not all possible white dots are given.

8. Minimum Cells
Grey cells with inward-pointing arrows represent minimums: the digit in the cell must be less than all orthogonally adjacent digits.
