Use the power of gravity to get the yellow ball into the black hole. To do this, you have to decide the angle and the power of each shot you make. You only get one shot per level, so take your time and make your shot count! The line in the bottom left corner of the screen determines the power of the shot. Click and drag it to the right to put more power into the shot. Then click on the ball and drag it left or right to determine the angle of the shot. Once you have it lined up perfectly, click Fire to let the ball go and see if it makes it to the hole!
