Theme: Clue Symmetry and Logic

Author/Opus: This is the 35th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Standard Fillomino rules. Also, all polyominoes should have rotational symmetry as in this example:

Answer String: For each cell in the marked rows/columns, enter the area of the polyomino it belongs to. Enter just the last digit for any two-digit number. Start with the 1st row, followed by a comma, followed by the 3rd column.

Time Standards (highlight to view): Grandmaster = 2:15, Master = 3:15, Expert = 6:30

Awesome variant 🙂

Is it original to GMP? Or are there more puzzles of this type out there?

• Jack Bross says:

This was a very nice variant. The interactions between the 4’s and 5’s are fun. I’d be tempted to call it Galaxy Fillomino after the superficial similarity with Spiral Galaxies, even though the actual feel of the puzzle is actually rather different.

I’ve seen them in a book sold in Beijing, Serkan is one of the authors: http://puzzle-toketa.blogspot.jp

03:59. Ouch, that one was a difficult variant.

Great construction. Felt like intuited at a few places, but I suppose that’s just me not being used to this variant, which is a new one for me too.
