Rules: Partition the grid into pentominoes so that every cell belongs to exactly one pentomino. A clue must belong to a pentomino of the clued shape (for the standard labeling of pentomino shapes see, e.g., the Wikipedia article on pentominoes); a pentomino may contain more than one clue or none at all. Pentominoes of the same shape must not touch by side.




This type was invented by Grant Fikes and introduced on Grandmaster Puzzles.
