Jezzball

The balls run on the floor, and no one can cope with them, but there is a way - to limit their space for movement. Use arrow, controlling the mouse icon, with its help you fill in the sturdy concrete solution, cutting areas and gradually reducing the area where the balls are worn. Press gaps change the direction of the arrows from vertical to horizontal and vice versa. Grout at least 70 percent of the field and go to the next level.
