Remix of a previous idea. I think the ruleset works quite nicely in a 3-star version, so here it is!
Rules:
Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.
The Valiant Viper: Draw a 1-cell wide, orthogonally-connected snake that does not branch, does not loop, and does not touch itself, not even diagonally.
Circles—Snake Knight Sums: Every circle is part of the snake and sees at least two other snake cells by knight’s move. A digit in a circle gives the sum of all snake cells within a knight’s move of that circle.
Squares—Non-Snake King Sums: Every square is not part of the snake and sees at least two other non-snake cells by king’s move. A digit in a square gives the sum of all non-snake cells within a king’s move of that square.
Example: Below is an example of the rules interacting.

Lösungscode: Column 7

Excellent puzzle. Enjoyed it from heart. Nice solvable path which uses combination of both the sudoku rules and custom rule set. I did mess up in first attempt. But after help from author corrected the course and able to do it.

Lovely puzzle Nordy, I did enjoy hunting the snake. Thank you. If you wish for a similar-ish sweeper cell + path combo, you could check out 000AMU from Wessel Strijkstra and I.
