How a flag football game works

1. Flag football is American football without contact. Two teams of five try to carry or pass the ball over the other team's goal line.
2. A ball carrier is stopped by pulling a flag from their belt, not by a tackle. That ends the play.
3. A team starts on its own 5-yard line with four plays, or downs, to get past the middle line, then four more to score. If it fails, the other team takes over.
4. A touchdown is worth six points, with one extra play after it for one or two more. The higher score wins.

How long

Two halves of 20 minutes, with a clock that runs almost all the time.
