Normal sudoku rules apply: Place the digits 1-9 once each in every row, column and 3x3 box.
Region sums: blue lines are divided into sections by the box borders. Each section of a line has the same sum. Different lines may have different region sums.
Kropki: Where two cells are connected by a black dot, one is double the other. Where two cells are connected by a white dot, they are consecutive.

I judge difficulty on time taken to solve, roughly speaking. This took me 8 minutes which is quicker than some GAS puzzles, therefore it is 1 stars for me

The difficulty rating on this site is so of. This is not a 1 star. Its not like you can give this to anyone and they will be able to solve this. That for me is 1 star puzzle.
But never the less this is great puzzle thank you for sharing

Reply: Thanks to you and others for the feedback - much appreciated! Glad that so many seem to like this series so far :)
I must admit I agree somewhat regarding the ratings on here - I usually find the expected difficulty rating I upload is one star higher than the final score that comes out. I intended this series to rank at 2-3 stars per puzzle, but perhaps I just always over-estimate the difficulty of my puzzles...
