Solve the Sudoku and make the digits on each arrow path sum to the digit in its circle.
Step by step

Controls

A useful example
A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction.
