Clueless Kropki Sudoku 1

(Published yesterday, 12:03 by AlfSmith)

• Normal Sudoku rules apply.

• Kropki: Two orthogonally connected cells joined by a white dot contain consecutive numbers. Two orthogonally connected cells joined by a black dot contain numbers where one is double the other. All possible dots are given.

• A gold cell contains its position within its row, column or box. Position is read from left to right, top to bottom.
For example the gold cell R9C4 contains either 4 (position in row), 9 (position in column) or 7 (position in box).

• All possible gold cells are given.
For example the white cell R3C2 does NOT contain 2 (position in row), 3 (position in column) or 8 (position in box).
