Serve spin types

Hi sir,

What kind of spin can be generated thorough serve. I know 

1.back spin

2.left side spin

3. Right side spin.

4.underspin 

5.top spin.

We can do more of them?

Hi Kedar,

Backspin and underspin are the same.  However if you imagine the ball as a clock face the topspin you can imagine the ball rolling straight forward over 12 o'clock.  The backspin the ball roll straight backwards over 6 o'clock.  The two sidespin are spinning over 3 and 9 o'clock.  However there are an infinite number of other points around the clock that the ball can spin.  So really there are an unlimited number of types of spin that you can generate.
