and is most often implemented in one-on-one games. In this version, the play does not end once the ball crosses the goal line; instead, the player with the ball must change direction and advance it all the way back to the other end zone for two points. The game ends when a pre-determined number of touchdowns or points has been scored, or an arbitrary time is reached (for instance, dusk or the start of school). Penalties are rare and are usually only enforced in the most egregious cases, such as serious injuries or blatant pass interference. Most games use the honor system in lieu of a referee and/or an officiating crew. Leagues Organized sandlot football has been around since as early as 1908; in that year, a circuit was launched in Rochester, New York after the city banned high school football in its schools. The circuit produced a team known as the Rochester Jeffersons, who later joined the National Football League as a charter member in 1920, as well as several other teams that lasted into the 1930s. Street football is usually played as a pick-up game and has very little organization. In video games Street football has been used as the basis for two very different video games. EA Sports's NFL Street is a rules-light version of football played by NFL stars, similar to the Blitz series created by Midway Games. Atari's Backyard Football series, on the other hand, is a more kid-friendly game with players including child versions of NFL stars. References Variations of American football
