Normal sudoku rules apply.
Digits in cages do not repeat, and sum to the small clue, if given.
Box borders divide blue lines into segments with the same sum.
Black dots separate digits where one is double the other.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 9

Tricky break in (at least 2.5*). The rest of the puzzle is basic sudoku (a lot of numbers are easy to find due to the interactions between cages and lines). Average difficulty rating of 2* for me.

It's about time someone jailed region sum lines. Now lock up dutch whispers and throw away the key. Very fun solve!

Absolute doozy of a break in but a stellar puzzle from start to finish.

I love puzzles that flow from the first digit to the last digit with such beauty and skill. Thank you Blobz.

The break-in took me 90 minutes of copious pencil-marking and brute-forcing every combination I could think of until something finally gave way (guessing I missed something), but after that it was very smooth. Thanks for sharing.
