This is an example of a completed Kropki Sudoku. Kropki Sudoku puzzles take place on a standard 9x9
Sudoku grid, but there is a mixture of black and white dots between the cells to tell you about the
relationship between the values in those cells,
- Black dots: One of these cells is double the value of the other cell.
- White dots: One of these cells is one bigger than the other cell, i.e. they are consecutive values
It's also important to note that if there isn't a dot between two cells, that means that they are neither
consecutive or double the other, i.e. all dots are given.
