Flag football is a version of American or Canadian football. The rules are not very different to those of the regular game. Instead of tackling players to the ground, the other team must pull a flag or flag belt off of the player carrying the ball.[1] Flag football is a game played with no padding. Full contact is not allowed. The first game of flag football was played in the 1930s.[2] It was later played on military bases in the 1940s as a game for the military.[2]
Flag football games are 36 minutes long.[1] They are divided into two 18-minute halves. The only time the clock is stopped is in the last two minutes.
