The brief
Normal sudoku rules apply.
Cells separated by a knight's move or a king's move cannot contain the same digit.
Any two orthogonally adjacent cells cannot sum to 5 or 10.
Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 1:2 ratio. Not all dots are given.
Grey lines are palindromes and must read the same in both directions.
