Pentomino by Zoltán Horváth


Theme: Logical (Originally on 2014 Hungarian Puzzle Championship)

Author/Opus: This is the 6th puzzle from guest contributor Zoltán Horváth.

Rules: Place all 12 pentominoes into the grid, rotations and reflections allowed. Pentominoes cannot touch each other, not even diagonally. Pentominoes cannot use any of the black squares. Outside numbers indicate how many cells in that row/column are part of pentominoes.

Answer String: Enter letters for all pentomino segments from left to right in the marked rows, with one letter for each cell it appears in (e.g. LLLLIV,XXXUU). Separate each row’s entry with a comma and use CAPITAL LETTERS.

Time Standards (highlight to view): Grandmaster = 7:30, Master = 12:30, Expert = 25:00

Solution: PDF; a solution video is available here.

    Can this be called a Radar Statue Park?

    • drsudoku says:

      This puzzle has no connectivity constraint so it is not a proper Statue Park. I’d call it a pentomino battleships if you need to name it something else.

      • Neelix says:

        Perhaps not an explicitly stated one, but change the black squares to white circles and the “no diagonal touching” rule enforces that same connectivity. That said, your battleships association also seems to be appropriate. 🙂

        • Grant Fikes says:

          There are certain placements of a single pentomino that are forbidden in Statue Park because they divide the grid by themselves. Try placing an X against a corner.

        • Neelix says:

          @Grant Good point. 🙂

          – Neelix

          All good points. I probably should have highlighted the no diagonal touching rule which is a more serious departure for this puzzle style compared to Statue Park than just the connectivity bit.
