Flood Fill is a unique puzzle game where each piece of the puzzle must be filled using one of 4 colours without letting 2 adjacent pieces be filled with the same colour. There are 20 progressively more difficult levels, and an extra award for completing each level using the fewest possible colours.
Select a colour from the palette, and click on shapes with the mouse to fill them with that colour. Click a shape twice to remove its colour. 1,2,3,4 or A,S,D,F = shortcuts to select blue, green, orange and red paint.
