Normal sudoku rules apply.
Black dots indicate that digits in the connected cells have a ratio to 1:2. White dots indicate that digits in the connected cells are consecutive. Not all dots are given (no negative constraint).
Each grey dot may function as either a black dot or a white dot. However, half the grey dots are false, indicating that digits in the connected cells are neither in a 1:2 ratio nor consecutive. In each row and column that FULLY contains two grey dots, one is true and one is false.
