Fillomino (PuzzleMadness)
Divide the grid into groups where each number is the size of its group.
Every day: A new dated Fillomino puzzle every day, the same for every player, one for each size (Small, Medium, Large and Mixed); completed puzzles score on monthly and all-time leaderboards and past days stay in the archive. New puzzle: Once a day (the site does not state the time).

PuzzleMadness posts a new Fillomino puzzle every day, the same grid for every player, at several sizes. Fill every square with a number so squares are joined into groups whose size equals their number, and no two groups of the same size touch side by side. Finished puzzles score points on the site's monthly and all-time leaderboards.
About Fillomino (PuzzleMadness)
Fillomino asks you to split the grid into groups of squares joined side by side, where every square in a group holds the group's size. A group of three holds three 3s. Two groups of the same size may not touch along an edge, or they would be one group. The start gives some numbers, and on PuzzleMadness every group has at least one given number, so you never invent a new group.
The daily page opens today's puzzle on its own, and its title carries the date (on 3 October 2026 it read "Daily Medium Fillomino Puzzle for Saturday 3rd October 2026"). There is a separate dated puzzle for each size: Small, Medium, Large and Mixed. Past days stay in the archive, so a missed puzzle can be played later, and there is a print version and an image download of the grid. PuzzleMadness does not publish solutions: the site tells you when you have finished a grid correctly or made a mistake. Each completed puzzle adds to your total on the Fillomino monthly and all-time leaderboards, where only your best score on any one puzzle counts.
Grow the given numbers that can only expand one way first. Completed groups change colour on PuzzleMadness, which makes it easy to see what is done. Watch for 1s, which close at once, and for two equal numbers near each other that must either join or be kept apart.
PuzzleMadness is a British puzzle site with dozens of daily puzzle types in the browser, from many sudoku variants to logic grids such as Nurikabe, Hashi and Slitherlink. It is free to play and carries ads. A free account keeps track of the puzzles you have finished and puts your name on the leaderboards, and the badges next to usernames mark how many puzzles a player has completed.
How to play Fillomino (PuzzleMadness)
- Open the day's Fillomino page and choose Small, Medium, Large or Mixed.

- Fill squares so each group has as many squares as its number.

Tips
- A group that is complete must be surrounded by squares holding other numbers.
- Two equal clues close together might be the same group; count whether they fit.
- Empty squares enclosed by finished groups must belong to a nearby clue that can reach them.
Questions
Do you ever need to make a group with no given number?
Not on PuzzleMadness; its rules page says each group always has at least one given number.
When does the PuzzleMadness Fillomino change?
Once a day: each puzzle is dated, and the daily page opens the current day's grid. The site does not say at what time the new one appears.
Is PuzzleMadness Fillomino free?
Yes. You can play without an account; the site shows ads. A free account records which puzzles you have finished and enters your scores on the leaderboards.
Where can I find the answers?
PuzzleMadness does not publish solutions. It tells you when your grid is complete and correct, and when you have made a mistake.
Can I play earlier Fillomino puzzles?
Yes, older puzzles are in the archive, and puzzles completed on any day count toward that month's leaderboard.
