Rules
Normal sudoku rules apply.

Seventropy Lines: Every set of 3 adjacent digits on a dashed peach line must contain a digit from each of the seven-sum subsets of {1,6}, {2,5}, and {3,4}. A 7, 8, or 9 may not appear on a seventropy line. Digits on a line may repeat if allowed by other rules.

Circles: A digit in a marked circle is the sum of all orthogonal neighbours within its box. Small arrows are given as reminders of which cells count toward the sum.

Solution code: Row 1 from left to right. (9 digits)

Really beautiful and smooth coloring puzzle. There was one tricky spot that was a joy to overcome.

Really great puzzle! Many nice logical deductions to make, none of them extremly difficult.
Still, my solving time was close to the time I usually need for 3* puzzles.

Thank you for this wonderful puzzle, MSDOS! I found it harder than 2 stars, but also probably overcomplicated some steps. But be that as it may, I had a blast solving this one.

MSDOS: Really glad you enjoyed it, thanks for the comment :)
