Serve underhand, diagonally, from behind the baseline into the opposite service court.

In traditional side-out scoring, only the serving team scores a point.

The serve must bounce, then the return must bounce, before either side volleys.

Do not volley while you or anything you wear touches the kitchen.

Call balls clearly and give opponents the benefit of doubt on close lines.

League format rules supplement official playing rules; they do not silently replace them.
