Welcome to

A small daily Fillomino puzzle.
the rules
Fill every cell with a number.
Every blank square gets exactly one positive integer.
Same numbers, side by side, form a region.
A region's size must equal its number — a region of 3s has exactly three cells; a region of 2s has exactly two.

They must be separated by a cell of a different value — otherwise they'd just be one bigger region.

step 1 of 3
Start small
The smallest board there is. Two blanks — and the numbers already on it tell you what goes in them.
Tap a blank cell to pick a number.
The 1 is already a finished region — a region of 1 is a single cell.
step 2 of 3
Draw with your finger
Tapping every cell would be slow. Two drags do the work instead.
Drag out from the 4 to grow it — that region needs four cells.
step 3 of 3
Now the walls
A real little puzzle. Walls are how you pin down what you've already worked out.
This cell can't connect to the 2s on either side. Draw walls to visualise this.
every gesture
- drag
Fill — from a numbered cell, to paint neighbouring blanks with it.
- drag
Erase — starting on a blank cell, to clear everything you cross.
- tap
Pick a number — opens the picker on that cell.
- drag
Draw a wall — along the seam between two cells, corner to corner.
- toggle
Auto lines — draws the obvious walls for you and flags mistakes. Switch it off for a pure pencil-and-paper solve.

Hint — finds a cell you can already fill in. The easy ones it just fills; for a trickier step it walks you through the reasoning.
