In 1895, when 12 clubs decided to split from the Northern Rugby Football Union, few could have envisaged that 100 years later, the game of rugby league would become the second most popular spectator sport in Britain and spread as far and wide as Australia, New Zealand and even Papua New Guinea. Two teams take part in a game of rugby league with 13 players on each team at "kick off". Each team also have 4 substitutes/replacements available to bring on at any appropriate moment in the game. Each teams "13" is made up of 7 "backs" and 6 "forwards" . The backs are generally regarded as the attacking players and usually have more pace than the bigger more powerful forwards who are usually the "yard" makers. The object of the game is for one team to score more points than the other team. There are 80 minutes in which to do this. A team can score points through scoring a "try" or kicking a "goal".
