Theme: Clue Symmetry and Logic

Author/Opus: This is the 20th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Standard Fillomino rules. Also, all “1” polyominoes should be treated like queens in chess; no two queens (“1s”) can see each other in any row, column, or diagonal as shown in this image.

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 4th column, followed by a comma, followed by the 8th column.

Time Standards (highlight to view): Grandmaster = 3:00, Master = 5:00, Expert = 10:00
