LOST

Normal sudoku rules apply.

Adjacent digits along green lines differ by at least 5.

Cells separated by a dot contain digits that differ by the amount shown.

One each of the twelve standard pentominoes (no repeats by rotation or reflection) must be placed into the grid. Each pentomino touches exactly two "difference" dots and no pentomino enters a cell with a green line.

The arrangement of pentominoes must be deduced.

Once placed, each pentomino behaves like a 5-cell killer cage: digits do not repeat and must sum to the value listed in one of the pentomino's cells.
