It's not confirmed whether or not every galaxy's got a black hole at it's core. And the spin direction depends on your point of view.

my thoughts and i might be wrong... but i think galaxies are caused by supernovas that eventually explode and then implode, sucking everything into their 'black hole' so it would kinda be like a bathtub drain but they would go in different directions depending on their placement in the universe.

No Our current theories about the Universe have it that galaxies should not prefer to rotate one way or the other, and we should therefore observe as many clockwise rotating spiral galaxies as anti-clockwise. This is related to a fundamental assumption we make in cosmology; that there are no special places or special directions in the Universe. Thanks to the spiral arms, it is straightforward to observe the rotation direction of spiral galaxies (clockwise or anti-clockwise) just by looking at them Generally galaxies rotate, and the details of their rotation (angle, speed, direction) depends on the way that they formed and on the properties of the space around them - such as the presence of magnetic fields, or the tidal pull from other structures. learn more visit http://www.galaxyzoo.org/Default.aspx
