Solve on F-Puzzles

Rules: Normal Sudoku rules apply. Digits may not repeat within cages (regardless of cell colour). In the final grid, one or two orthogonally-adjacent cells in each cage will be green. Read left-to-right or top-to-bottom, they give the sum of the white-cell digits in the cage. Some green cells are for the solver to find. So, a four-cell cage could be green 1, 2 with white 3, 9 (12 = 3 + 9); green 6 with white 1, 2, 3 (6 = 1 + 2 + 3); etc.
