Playing footbals requires lots of rules. You must run fast. You can hit the balls, play together with your team, but you can't cheat in any way possible. You can't hit players of other team in order to win and take the ball. But you can take the ball from them by playing. You must pass the ball to other players of your team and operate with them but you mustn't operate or pass the balls to the players of opposite team. Как то так честно правил не знаю, все из головы )
