Normal sudoku rules apply.

Cells separated by a (chess) knight's move cannot contain the same digit.

Digits along an arrow must sum to the value in the connected circle. Digits may repeat on arrows if allowed by other rules.

A path consisting of the digits 1 to 9, in order, crosses from left to right across the grid with each digit in its corresponding column (1 in column 1, 2 in column 2, etc.) The cells along the path are connected orthogonally or diagonally.

A similar path crosses the grid from top to bottom, starting with a 1 in row 1, then a 2 in row 2, ending with a 9 in row 9. Again, cells along the path are connected orthogonally or diagonally.

The paths (neither of which appear on an arrow or circle) are to be determined by the solver.

Clarification: The two paths do not share any cells.
