Normal sudoku rules apply.

Digits separated by an X sum to 10. Digits separated by a V sum to 5. Not all X's and V's are shown.

Grey lines contain repeated digits. Green lines contain digits that differ by at least 5.

The indicated 60-cell white region contains one each of the twelve standard pentominoes (no repeats by rotation or reflection).

Each pentomino is "stitched" to two other pentominoes by a green or grey line.

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 its cells.
