To aim, swipe your finger / mouse across the screen and choose the right angle to launch the balls. You need to destroy all the blocks on the playing field by hitting them with balls. The balls will bounce off walls and bricks, so aim carefully to destroy as many blocks as possible with each ball launch. Keep the balls in the game: if the balls fall to the bottom of the screen, all the blocks of bricks will move up, if at least one brick reaches the top, then you will lose.
