Lines3D is a superb puzzle game. It is the classic lines game with some variance and an attractive interface. The game is easy to learn but not so easy to master. The board has 9*9 cells. You need to move the balls and align five balls of same type. Each time you complete a row, your score increases. But the hitch is that with each move, three more balls are added to the board. You have to prevent the board from filling up.
