Rule clarity: Standard Sudoku rules apply. A white dot means the two digits are consecutive. A black dot means one digit is exactly double the other. If no dot is shown between two orthogonally adjacent cells, then neither relation applies.
1 and 2: When 1 and 2 touch, the clue is treated as a black dot.
