Theme: Double Vision

Author/Opus: This is the 7th puzzle from guest contributor Carl Worth. The theme was inspired by Grant’s “Single Vision” Pentopia.

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 = 4:45, Master = 7:00, Expert = 14:00

• Grizix says:

Wow, really, so much time ?
I’ve made it in 5:45 without speeding up, neither intuiting, I’m really surprised that the time for grandmaster is so much !

Am I nearly a grandmaster in pentopia ? Doubt that …

Thanks everyone for the kind thoughts. I hope you all enjoyed solving these as much as I enjoyed composing them. As for more Pentopia, we’ll see what new ideas might strike me in the future.

Para, thanks for inventing Pentopia—it’s a really great puzzle genre, which seems rich enough for quite a bit of exploration still. And thanks for sharing your puzzles. I’ve still only worked through less than half of the Pentopias on your website. They are good and tough!

I like that the presentation here adds arrow heads. Without those, it can be easy to confuse the single-arrow and the two-arrow-across-from-each-other clues.

• Para says:

I know, the arrow presentation is nicer. But as I make all my images in paint, using lines is a lot quicker. I took the lines from the original Myopia presentation. It would be clearer if the lines just touched the edge of the cells, but I didn’t really like that presentation.
