Fillomino - PuzzleMonster

Fillomino is a number logic puzzle. Fill every cell so the grid splits into blocks: a block is a group of touching cells with the same number, and it must contain exactly that many cells. Two blocks of the same size can never touch. Some numbers are given as clues, and you shape every other block yourself. Every puzzle has one solution and can be solved by logic alone, so there is never any guessing.

Features:
• Pick a number once, then tap cells to fill them. Tap a filled cell again to clear it
• Blocks are tinted by number. A finished block gets a solid outline, and a block that grows too big turns red
• Undo takes back your last change with one tap
• Three grid sizes: 5x5 Easy, 7x7 Medium, 9x9 Hard
• Endless generated puzzles (polyominoes), free to play
• Unfinished puzzles are saved, shown on the menu with their progress, and resumed with one tap
• Stats, best times and streak tracking
• Light and dark themes and large text support
• Optional haptics
• Plays fully offline
• No third-party ads, only occasional suggestions for other PuzzleMonster games

A clean, satisfying puzzle for deduction fans. If you like Sudoku, Nurikabe or Slitherlink, Fillomino will feel right at home.
