About this game

Fillomino is played on a rectangular grid with no standard size; the internal grid lines are often dotted.
Some cells of the grid start containing numbers, referred to as "givens". The goal is to divide the grid into polyominoes (by filling in their boundaries) such that each given number n in the grid is part of an n-omino and that no two polyominoes of matching size (number of cells) are orthogonally adjacent (share a side).

Love this puzzle app. There's lots of puzzles & the interface is great. There is a banner ad at the bottom & optional ad for extra hints. No intrusive ads every minute or so like some games. The only problem is that not all 1's, & sometimes even larger groupings are placed on the board. These invisble groups make it impossible to solve the puzzles (especially the larger ones) without frequent hints. Because there's no clue to indicate these invisible groups are even there.

Finally solved the last one today, after many years. Last page, bottom row, second from left. I won't watch ads, so never tried for any hints. Great game.

On the 4th page, on the 4th row the puzzles 2, 3 and 4 are provably unsolvable - there's a block of 5 squares with number 6 in it on the starting position.
