LinesLines (aka ColorLines) is a Computer puzzle game, first introduced as a video game by the Russian company Gamos in 1992.
The game field is a square 9x9, where balls in different colors appears frequently. The goal is to clean maximum numbers of lines of arranged balls of same color (five or more). Player can move every ball, if there is a path (linked set of vertical and horizontal empty cells) between the current position of the ball and the desired destination. When a line of five or more balls in same color is arranged (horizontal, vertical or diagonal) it disappears.
