A calm logic puzzle where each group of numbers must occupy exactly as many cells as its value. Follow a puzzle journey, try the daily challenge or practice at your own pace.
About Fillomino
Fillomino turns a grid of clues into a compact deduction challenge. Fill the empty cells to form connected regions of equal numbers. A 1 occupies one cell; a 3 needs three cells, all marked 3. Equal groups that meet along an edge merge, so every move changes the space available for other regions. This Zarocer edition follows classic Fillomino rules. Diagonal contact does not connect cells, and the starting clues remain fixed. A region may contain several clues or no clues at all. Instead of simply copying a nearby number, consider each region’s size and boundaries. The journey begins with small boards and gradually increases the challenge. Daily mode gives everyone the same board for each UTC day, selected from a finite collection of original puzzles with rotations and reflections. Practice lets you choose a difficulty. There is no time limit, and you can pause, erase an entry or ask for help. Play with a mouse, touch screen or keyboard. Progress and active puzzles are stored locally when browser storage is available. Results are local; global ranking is not yet available. Restored games and games using assistance are identified separately. No account is required, and the build contains no ads or trackers.

How to play
Select an empty cell, then tap a number on the panel or type it. Fill every cell with a positive whole number without changing the starting clues. Build regions of equal numbers connected along edges; diagonal contact does not count. Each region must contain exactly as many cells as its number. Separate regions of the same number cannot share an edge. A region may contain several clues or none. Use arrow keys to move, Delete or Backspace to erase, Ctrl+Z to undo and Escape to pause. Hints, undo and checking mark the game as assisted.
