- No spinning. Spinning is defined as >360 degree rotation.
- Games are nominally 10 points.
- Must win by 2 points (e.g. 13 to 11 goals)
- Both sides must touch the ball (not counting incidental glancing at high ball speed) before a goal "counts".
- Ball serves should be "soft" - a light roll with a tiny drop. Not a big drop and "bang!" sound.
- Ball serves should go down the midline, a slight bias (accidental or intentional) in either direction is fine. But should not escape the center players without bouncing off the opposite sidewall first.
