Click and hold the mouse button toward the bottom of the screen, then fling the mouse forward and release the button to throw the ball. Flinging the mouse to the right or left will cause the ball to roll accordingly. Your score will increase by the number of points indicated on the target your ball goes into. Bonus balls: score a red ball and receive double points indicated by the target. A blue ball quadruples the target points! Bonus targets: score a ball in a yellow glowing target and get a free ball! Bonus round: score 600 or more total points before running out of balls and get three extra balls!
