To pass the offensive human-player stopped the action. Then he retrieved the, . . . umm, . . . "passing device" - something like a tiny steam shovel bucket on the end of one arm of a spring-loaded, . . . umm, . . . catapult-player. Yeah, that's the ticket, . . . it was a teeny catapult-player.
That's it, . . . in the middle of the players circle.
Anyway the offensive human-player held the catapult-playeqr adjacent to the quarterback pressed something, and the ball - actually a tiny slightly-rounded rectangular-solid cotton ball - flew. (Maybe the catapult-player was supposed to be on the field from the beginning of the play, since he had "legs". But he was inherently unstable and would not stay upright beyond a few seconds.)
Anyway the "ball" was retrieved and placed on/in the nearest offensive player. The "ball" might've gone in any direction and even well off the playing field. Nonetheless, the nearest offensive player was determined by eye, . . . or by intense negotiation between the human players.
Play resumed by turning the field back on. Even if the "ball" had been placed in a player ahead of the pack and near the goal line, there was an excellent chance he would reverse field or "run" in a circular pattern. Or end up running to the sideline and out-of-bounds. So it really didn't matter which player "caught" the ball. Oh, . . . and there was a good chance that the player would fumble anyway, as the vibrating field would eventually dislodge the ball from the opening between the players legs where the ball normally resided, . . . just like in a real person.
Great fun!
