Color Lines is a game play on 9×9 board with balls of seven different colors. The object is to connect 5 or more balls of the same color to a horizontal, vertical or diagonal line. The player can move one ball per turn, and the player may only move a ball to a particular place if there is a path (linked set of vertical and horizontal empty cells) between the current position of the ball and the desired destination. If the player does form such lines of at least five balls of the same color, the balls in those lines disappear, and he gains one turn, i.e. he can move another ball. If not, three new balls are added, and the game continues until the board is full. For more challenges and fun, hard mode was introduced, in this mode there will be frozen balls appear after several turns, these balls are unmovable. If you remove a line with frozen balls, the points also can be doubled.
