Some main rules and regulations of rugby are that the ball cannot travel forward off a player's hands, tackling must be done only from below the neck and tackles must be made with both the hands and the shoulders. Additionally, once a player is tackled he must release the ball.
Since a ball cannot travel forward off a player's hands, there are no forward passes or dribbling allowed in rugby. To advance the ball, it can be kicked or carried forward. If the ball is passed, it must be done laterally or backwards. If this rule is broken, then the opposing team gets a scrum.
There are two teams in rugby and each team has fifteen players. In a scrum, eight of the fifteen players, also known as the forward pack, engage with three in the front, four in the middle and one in the back. Both packs push forward in the same formation and the team that didn't commit the foul puts the ball into the middle of the scrum. The goal is for the ball to come out at the back of the scrum in order to regain possession of it.
With regard to tackling, pile driving is also prohibited. The goal of rugby is to score; a score is five points. To score, the goal line must be crossed and the ball must touch the ground..
Rugby games are 80 minutes long and have two 40 minute halves.
