This puzzle is reusing the constraint that I introduced in Triangular Growth. I've come to calling it “triangular lines” because by definition, the length of such a line is a triangular number. But if anyone has a better suggestion, or this constraint has in fact been used and given a name before, let me know!

Rules

Normal Sudoku rules apply.

Every line has a beginning and an end. The direction is to be determined by the solver.

Starting from the beginning, split a line into segments. The first cell is the first segment, the next two cells are the second segment, the next three cells are the third segment, and so on.

All segments on a line have the same sum. This sum may be different for different lines.
