A FILLOMINO puzzle consists of a square grid in which some of the squares contain a single digit number. To complete the puzzle,
a Solver must place numbers in the blank squares so that the puzzle is divided into zones with the area of each zone equal to the number contained within its
squares. The zones may take on any shape, but zones having the same area may not touch each other.
When you have determined what number should be contained within a square, you can move the cursor to that square using the arrow keys,
or you can mouse click directly into the square. Any number typed on the keyboard will then be placed into that square.
If you make a mistake, you can overtype it with a different number, or you can remove it entirely using the Space Bar.
