Toroidal kropki Sudoku
Place the digits 1 to 9 in every row, column and colored area. Same colored areas wrap around the grid from top to bottom or from left to right.A white dot means: the difference between the digits in the two neighboring cells is 1. A black dot means: one of the neighboring digits has the double value of the other.
If there is no dot between two cells, none of these constraints is true.
Solution code: Column 9, followed by row 7
