Lines is a Collapse-based arcade-style strategy game where you have to keep your board as free of incoming balls as possible for the duration of the game. A player moves the balls to form lines of 4 or more balls of the same color vertically, horizontally or diagonally. Such lines of 4 or more balls are immediately deleted and points are scored. The longer the deleted lines the more points you will get. To move a ball click on it to select, then click on destination square. After each turn three new balls randomly added to the board. The game is over when the board is filled up.
