Filling
Game Rules: Write a number in every blank square of the grid. When the grid is full, every orthogonally connected group of identical numbers should have an area equal to that number: so 1s always appear alone, 2s in pairs, and so on. To place a number, click in a blank square to select it, then type the number you want. You can also drag to select multiple squares.
