By clicking on the ball (indicating the throwing position) that is faintly floating near the foul line, CAT will throw the ball at that position, and if it hits a pin, only the pin that was hit will fall. Therefore, unless something extraordinary happens (which is almost impossible?), you won't get a strike. Please try to get a spare. The direction of the ball and the curve after it is thrown will differ depending on where you click. It's not random. If you click anywhere near the foul line other than the ball before clicking on the ball, the ball's position will change.
