The rules:

Normal sudoku rules apply. Place the digits 1-9 exactly once in every row, column, and 3x3 box.

Kropki: Digits separated by a white dot are consecutive. Digits separated by a black dot have a 1:2 ratio, meaning one is exactly double the other. Not all dots are necessarily given.

Three of my puzzles which are yet to be rated:
Pacman in the big city
Really, don't open the box
Why did you open that?
If you enjoy this one, please try them too.

Solution code: Row 5

Nice puzzle but I found it tough at times - maybe should be nearer 3 stars?
