How do you play Racquetball

[Kel_Varnsen_Latex_Division]

Ball hits raquet, must then hit wall,
can then bounce once, or not at all.

Serve while standing between the prallel lines at mid court. The ball can hit whatever you want it to, as long as it hits the front wall before it hits the floor.
On a serve the ball has to be on trajectory to hit in the back half of the court floor.

On a non-serve does a player just have to have the ball hit any wall or does the ball have to hit the front wall?

On the serve can you hit the ball so it just barely bounces just before the back corner? How could someone return this shot?

Is there a line the front wall that means something?
