Click within the applet, choose number of players. When it is your turn, watch the blue arrow as it rotates: this shows the direction of the ball. When you have chosen the ball's basic direction, click AND HOLD the left mouse button.
You now have chance to put spin on the ball - just move the mouse left or right while holding the button down and you will see the "spin gauge" change at the bottom of the alley. This gauge shows how much spin the ball will have. When you are happy with the amount of spin, release the mouse button, and the ball will start down the alley.
You can switch the lane bumpers on by pressing the 'B' key (press the 'B' key again to switch them off).
