By clicking on the ball (indicating the throwing position) that is floating faintly just in front of the foul line, the CAT will throw the ball at that position, and if it hits a pin, only the pin that the ball hits will fall. So unless something extraordinary happens (almost none?), you won't get a strike. Please try to get a spare. Depending on where you click, the direction of the ball and the curve after it is thrown will be different. It is not a random number. If you click near the foul line other than the ball before clicking on the ball, the position of the ball will change.
