Theme: Clue Symmetry and Logic (or Empty Middle)
Author/Opus: This is the 61st puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Standard Pentopia rules: Place some of the given pentominoes in the grid so that no pentominoes are in adjacent cells that share an edge or corner. Pentominoes cannot repeat in the grid; rotations and reflections of a pentomino are considered the same shape. The arrow clues indicate all the directions (up, down, left, and right) where the nearest pentominoes are located when looking from that square. (Arrow clues cannot contain pentomino shapes.) Also, see this example:
Answer String: Enter the length in cells of each of the shaded pentomino segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma. The example has the solution “21,23”.
Time Standards (highlight to view): Grandmaster = 4:15, Master = 5:30, Expert = 11:00
