Rugby is played at a fast pace, with few stoppages and continuous possession changes. All players on the field, regardless of position, must be able to run, pass, kick and catch the ball. Likewise, all players must also be able to tackle and defend, making each position both offensive and defensive in nature. There is no blocking of the opponents like in football, and there are only five substitutions per game allowed for each team. A rugby match consists of two 40-minute halves.
Rugby is played on a field, called a pitch, that is longer and wider than a football field, more like a soccer field. A typical pitch is 110 yards long 75 yards wide. Additionally, there are 10-22 meter end zones, called the in-goal area, behind the goalposts. The goalposts are H-shaped cross bars located on the goal line and are the same size as American football goalposts.
The rugby ball is made of leather or other similar synthetic material that is easy to grip and does not have laces. Rugby balls are made in varying sizes (3, 4 or 5) for both youth and adult players. Like footballs, rugby balls are oval in shape, however are rounder and less pointed than footballs to minimize the erratic bounces we see in football.
