Hello, everyone. With much appreciated contributions from Lizzy01, here is a small construction for you to enjoy.

CTC:

Please evaluate the puzzle and leave feedback. This helps me construct better puzzles.

Standard Sudoku rules apply. Fill the grid so each row, column, and 3×3 box contains the digits 1–9 exactly once.

Region Sums: Region borders split the blue line into segments with equal digit sums.

Killer Cages: Digits in a cage sum to a given total and do not repeat.

Arrows: The digit in a circle equals the sum of the digits along its arrow. For clarity: two arrows from R6C6 overlap on three cells in box 9.

Quadruples: Digits shown in a circle must appear in the four surrounding cells.

Solution code: Row 9 from left to right. 9 digits in total

Good stuff. Liked that the "major" break-in had to be accompanied with minor steps. Though sometimes i tend to go with the feeling "this hast to be right" rather than find the clean logical steps. Thx for setting!

Lovely! Took me a while to get the break in, very elegant though! Realky enjoyed it.

Very nice break-in. Flow after that was very smooth. Nicely done
