Professional rugby is a competitive sport played by teams of fifteen players each, known as rugby union, or seven players each, known as rugby sevens. The game involves carrying, passing, and kicking an oval ball to score points by touching it down in the opponent's in-goal area or kicking it through goalposts. Professional leagues and tournaments, such as the Rugby World Cup and Six Nations Championship, attract large audiences and showcase top talent from around the world. Players often compete at club and international levels, representing their countries and contributing to the sport's global popularity.
