Author/Opus: This is the 432nd puzzle from our managing editor Serkan Yürekli.

Rules: Standard Fillomino rules: Divide the grid along the dotted lines into regions called polyominoes so that no two polyominoes with the same area share an edge. Inside some cells are numbers; each number must represent the area of the polyomino it belongs to. A polyomino may contain zero, one, or more of the given numbers.

Variation rules: No two polyominoes with the same area, or with areas that differ by one, can share an edge. Also, the number at the top left of each cage gives the sum of all numbers that appear inside of it. Numbers may be repeated in cages.

Difficulty: 5 stars

Time Standards (highlight to view): Grandmaster = 15:00, Master = 40:00, Expert = 1:20:00

Solution: PDF; this bonus puzzle was also featured in this Cracking the Cryptic video.
