Heads up that this puzzle is a bit more difficult than the ones we have recently been posting.
Normal sudoku rules: Every row, column, and box must contain a complete set of the digits 1-9.
Mod-4 Lines: Any three adjacent cells along the line must contain digits with three different remainders when divided by 4.
Kropki pairs: Cells separated by a black dot have a 1:2 ratio. Cells separated by a white dot must be consecutive. Not all dots are necessarily given.
