"Confused about what's going on at the 2014 World Cup? We can help.
Soccer -- more commonly known as football (but we'll stick with 'soccer' here to avoid confusion) -- is the most popular team sport on the planet. Originating in England in the 1800s before spreading rapidly around the globe, soccer is played with two teams of eleven players each, the objective generally being to score more goals than the other team in 90 minutes, split into two 45-minute 'halves'.
There is one ball, and goals are scored by getting into the ... goal. Regulation-sized goals are 24 feet (7.32 m) wide by 8 feet (2.44 m) high, and in order for a goal to register the ball must completely cross the line of the goal without any rules being broken by the scoring team.
The most notable aspect of the sport, of course, is that all but one player on each team, the goalkeeper, is barred from using their hands to touch the ball while the ball is in play. Every portion of the body bar the arms is legal to use."
