The Moon IS always the same shape; it's always round. That it doesn't always LOOK like a sphere is a trick of lighting.

As the Moon goes around the Earth, sometimes we see it only partially illuminated by the Sun, because we generally see only the part that is lit up. (If you look closely, you can see the rest of it dimly illuminated by reflected Earthlight.)
