- One (1) semi-regular spheroid with a mass of 23.888×1024 kg and volume of 4.326×1012 km3 . Casual participants are allowed to substitute this spheroid with any one with sufficient volume that they can all play, but official tournaments must use a spheroid of the denoted proportions. If the spheroid is not equipped with a regulation breathable atmosphere, participants must provide their own.
- One (1) universe wherein corporeal sentient life is physically capable of existing for long enough to develop the cultural practice of play (batteries included).
- One (1) self.
- Using one or more limbs each, all participants grip the spheroid.
- At a predetermined signal (ex. referee’s whistle), all participants shove the spheroid away from themselves as hard as they can.
- All participants then attempt to catch the spheroid as it falls back to them. Points are then distributed thus:
- Catching the spheroid using the same combination of limbs with which you initially gripped it: 10 points.
- Catching the spheroid with a different combination of limbs: 12 points.
- Failing to catch the spheroid: Disqualification.
- Repeat unless one or more participant/s are declared the winner.
