In the new Fill In 3D game, you can test your reaction speed and attentiveness. Before you on the screen you will see the playing field on which the gray text will be visible. A line of a certain color and a brush will be visible below it. You will have to quickly draw a brush along the line and thus absorb it. Now you will need to drive the brush over the inscription and thus paint it. As soon as you paint the whole word, they will give you points and you will go to the next more difficult level.
