Use the mouse to aim the ball. Once you've selected a spot on the lane to throw
the ball from, gently move the mouse back and forth to aim the arrow in the
direction that you want the ball to go. Click and hold the mouse to start a
second arrow rotating around the ball. Releasing the mouse will bowl the ball
down the alley. If you release the mouse button when the two arrows meet, the
ball will have no spin. If you release the button earlier or later, the ball
will spin in that direction.
