Normal sudoku rules apply. The digits along each blue/purple line multiply to 200. Draw a 1-cell wide, non-branching, orthogonally-connected road that does not touch itself orthogonally (but may diagonally). The two ends of the road are given as circles. The road contains only odd digits, and the digits along the road sum to 200. Except for the circles, the road CANNOT visit any cell that contains a given clue ie the road cannot visit the given digits in R2C9 and R9C1, nor any cell that contains a line segment.
