Region Sum Hitlines
Rules:
Normal sudoku rules apply.
Digits on a line can't repeat. We say a digit on a line is a 'hit' if it matches its position on that line, starting at the end with the square (which is 'position 1'). Eg: a line reading 423 would have two 'hits'; 2 (in position 2) and 3 (in position 3).
Additionally, box borders divide a line into segments. The sum of hits on each segment is the same (but this sum may be different for different lines). Every line has at least one hit.

A perfect 3* puzzle! Took me an hour of careful thinking, but at no point did I feel hopeless

I try to stay clear of my nemeses - the 3 star difficuly category and region sum lines but gave it a try after stumbling through your 4x4 pack.
Glad you made me face my fears as it was really good.

Found it tricky towards the end. Tip: if you think you've fully used all the clues, check, check again!

Crazy how this weak constraint can make it have an unique solution. Love the break in. 3* to me. Great setting thx.
