Theme: Unique Groups
Author/Opus: This is the 241st puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Variation of Pentopia rules: Place some of the given polyominoes in the grid so that no polyominoes touch, not even diagonally. Polyominoes cannot repeat in the grid; rotations and reflections of a polyomino are considered the same shape. The arrow clues indicate all the directions (up, down, left, and right) where the nearest polyominoes are located when looking from that square, ignoring the clue cell itself. Polyominoes can sit on the clue cells.
