The balls filled the tall flasks in the Ball Sort in a chaotic manner. Each one holds four balls, but the colors are mixed up. Your task is to sort and arrange the balls into flasks according to shades. There should be four balls of the same color next to the flask. While sorting, you can fill empty containers, and if you want to transfer a ball from one filled flask to another, you can do this if the ball you take is placed on top of a ball of the same color in another container. It is not possible to place a ball on the same one of a different color in Ball Sort. The game has hundreds of levels.
