Fillomino – Number Blocks

Place a number, and matching numbers join into a block.
That number is exactly the size of the block.
Undo any move, and pick up any unfinished puzzle right where you left off.

Fillomino is a classic pencil puzzle: fill every cell of the grid with a number. No arithmetic and no guessing, just careful observation and clean deduction. Start with a gentle 5×5 or take on a demanding 11×11, whether you have five minutes on the train or a quiet evening at home.
