Flag football is a popular variation of American football that eliminates the physical contact between players. Instead of tackling opponents, defenders must remove flags attached to the ball carrier's waist while the offense attempts to score touchdowns. Synonyms for flag football include touch football, flag football sevens, and non-contact football. Touch football refers to a similar game where players simply touch their opponents instead of tackling them. Flag football sevens is played with seven players on each team, while non-contact football emphasizes safety by eliminating physical contact altogether. All of these variations offer a fun and exciting way to enjoy America's favorite sport without the risk of injury.
