How to Solve a Kropki Sudoku Puzzle

Kropki Sudoku puzzles follow the basic rules of Sudoku: each number 1 through 9 must appear once (and only once) in each column, row and 3x3 subgrid. In addition, a white dot will appear between all adjacent consecutive numbers on the grid, and a black dot will appear between all adjacent number pairs where one is exactly half the value of the other. Each puzzle has one unique solution and guessing is never required.
