RULES AND FEATURES
A ball with an empty center (ring) is the center of gravity for all other colored balls that are attracted to it, trying to distribute themselves evenly around it. You can change the position of the center of gravity in the total mass of balls by selecting any one and clicking on it. Your main task is to move gravity so that groups or rows of four or more single-colored elements are created in the pile of balls, which will disappear, reducing the size of the pile.
