Flag Football is a popular game that takes its content from Football and is played all over the world in a variety of styles. The game itself functions almost exactly like a typical round of Football. There are two teams with a matched set of players and the goal, for either team, is to get the ball across the field into the goal area, or touchdown.

Instead of tackling, the brute force means of knocking an opponent down thereby disabling them for the play, a player must pull on and remove another players flags. A belt is worn with flags attached firmly enough to adhere during maneuvering, but loosely enough to be removed with a good tug. Football would otherwise be restricted to heavy, male players, but Flag Football opens the doors to players of all ages, genders, and body types.

It may be surprising to know that Flag Football is recognized internationally and is played in serious tournaments. There is a World Cup of Flag Football that draws teams from several foreign countries all over the world to a televised event sponsored by the International Flag Football Federation. To level the playing field, there is a subsequent International Woman's Flag Football Association, just like the Women's National Basketball Association in America.

Flag Football, like regular Football, can be played in the context of serious tournaments, community gatherings, international, national, state, city, and district tournaments. Many colleges and universities across the country feature Flag Football teams that compete against other colleges and universities. Even the National Football League in America, the commonplace name in all things professional football, holds a Youth World Championship for young teenagers in which teams compete globally in No-Contact Football. No-Contact Football is the general category in which Flag Football falls. No-Contact Football also includes other variations, like Touch Football.

English-speaking countries, by far, are not the only ones to popularize and conduct Flag Football games and tournaments. Korea, for one, has its very own Korean Flag Football Federation in which a league of teams competes countrywide. Players in these teams range in age from middle-schoolers to mature adults. Canada, Sweden, Norway, Mexico, Finland, and countless other countries follow suit with their own implementations of this.

The game of Flag Football is also very flexible. For this reason, and the advantage of no contact, Flag Football is a favorite intramural and physical education sport and can be seen in playgrounds, gyms, courts, and fields, all around the United States and the World. Games can be "9-man", "7-man", "8-man", etc, with a varying number of players on each team represented by the number preceding "-man". It's as simple as splitting a group of people up into evenly matched pairs and playing a game of Football. The ease of adaptability in Flag Football has also spawned experimentation, with some groups playing "20-man" Flag Football and crossovers, like Flag Rugby.
