Author/Opus: This is the 242nd puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Standard Pentopia rules: Place some of the given pentominoes in the grid so that no pentominoes touch, not even diagonally. 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:
Difficulty: 3.5 stars
Time Standards (highlight to view): Grandmaster = 5:30, Master = 8:30, Expert = 17:00
Solution: PDF and solving video.

I think the puzzle is ambiguous if clues can be shaded, but the rules don’t state that clues cannot be shaded.
Given how many Pentopia puzzles are on the website now, is it time to promote the genre to the sidebar? 😛
This is a good suggestion and I’ll work on gathering more about the puzzle history so we can make a proper Rules and Info page.
I second that. I struggled to solve it and resorted to glancing at the video to see that none of the arrows were shaded. Nice puzzle though 🙂
