Pointed Sum Loop
(Published on 30. December 2023, 00:19 by yttrio)
This is the fourth puzzle in a loop series that uses arrow clues. Links to the previous puzzles in the series are given below.
Pointed Whisper Loop
Pointed Dutch Loop
Pointed Modular Loop
Rules:
Normal Sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3x3 box.
Digits along an arrow must sum to the digit in that arrow's bulb.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- All arrow bulbs must be on the loop.
-- The digit in an arrow bulb gives the total number of loop cells in the 3x3 Sudoku box containing the bulb.
-- The loop acts as a region sum line. The sum of digits along the loop is the same in each 3x3 box the loop enters. If the loop enters a box multiple times, the sum is counted separately for each segment.
Solution code: Row 5

Very smooth and satisfying! But a lot easier than 4 stars in my opinion.
