If not let me tell you all about the BEST game in the world.
The idea is to Score a "try" wich is the same as a Touch-Down in American Football. You can only pass the ball behind you. and you can do ANYTHING to get the ball in your posetion! Its basicly a FREE FOR ALL. If the ball touches the ground play continues. If a floul is called, the teams go in to a "SCRUM" a scrum is where the teams lock sholders and the ball is placed in the middle, the idea of a scrum is to push you team over the ball so the person behind the scrum can pick it up and pass it so play can resume. if the ball goes out of bounds, there is a throw in (simmilar to soccer) each half is 45 mins. There are Yellow and Red cards, If you get a yellow card you are sent to the sin-bin for 5 mins, and your team can to replace you with another player. If you get a Red card you are ejected from the game, 2 Yellow cards = a red card.
What you cant do in Rugby
1. Bite people
2. Punch
3. Kick
all of these will earn you a Yellow or red card.
