What are the rules of rugby?

Rugby is played on a field that measures about 100 meters long and 70 meters wide, with two in-goal areas. Each match lasts 80 minutes, divided into two 40-minute halves, and involves two teams of 15 players each, including forwards and backs. Points can be scored through tries (5 points), conversions (2 points), and penalty or drop goals (3 points)^[1][2][5].

The game has specific rules, such as not passing the ball forward and requiring players to remain behind the ball. Tackles must be made below shoulder height, and various stoppages and restarts occur for infractions, such as knock-ons or offsides^[2][4][5].
