This puzzle should be comparable to the first one in terms of difficulty. In this one however, the solution path should be more streamlined.

Standard sudoku rules apply.
Standard killer sudoku rules apply, except no cage totals are given. Also one cage is bigger than 9 cells.
This cage is 'balanced' i.e. it contains each digit at least once and no digit more than twice.
Kropki rules do not apply to cells.
Standard Kropki rules apply to cage totals.
This means that cages connected with a white dot have consecutive cage totals.

Grey dots take the place of either a black or a white dot (to be determined by the solver).
Dots on the corner of four cages describe the relationship between each pair of diagonally adjacent cages.
These dots can not assume different colors for these two respective pairs of cages.
All possible dots are given.
