Theme: Clue Symmetry and Logic
Author/Opus: This is the 47th puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Standard Araf Rules (see below). Also, no two regions with the same size can share an edge. (Note: this is the same rule as in Fillomino puzzles where no equal size polyominoes can touch.)
Araf: Divide the grid into some regions formed of edge-adjacent squares. Each cell is part of one region, and each region should contain exactly two given numbers. Each region must have an area that is strictly between those numbers (This means, for two number clues A and B with A < B, the area C fulfills A < C < B). Answer String: Enter the number of cells in each connected group (between bold lines) in the marked rows.
Time Standards (highlight to view): Grandmaster = 4:00, Master = 7:00, Expert = 14:00
