I tinkered around with Counting Circles as a line constraint. This is the result :)
Rules:Normal Sudoku rules apply.
If a digit is on a yellow line, that many instances of that digit must be on that line.
The purple line is a Renban line that contains all 9 digits exactly once.
Solve online:Solution code: Row 5 (9 digits)
