These are the best football kickoff rules:
1. The kickoff shall be from the kicking teams 30-yard line at the start of each half and after a field goal and try. A kickoff is one type of free-kick.
2. A one-inch tee may be used (no tee permitted for the field goal, safety kick, or try attempt) on a kickoff. The ball is put in play by a placekick.
3. A kickoff may not score a field goal.
4. A kickoff is illegal unless it travels 10 yards OR is touched by the receiving team. Once the ball is touched by the receiving team or has gone 10 yards, it is a free ball. Receivers may recover and advance. The kicking team may recover but NOT advance UNLESS the receiver had possession and lost the ball.
5. When a kickoff goes out of bounds between the goal lines without being touched by the receiving team, the ball belongs to the receivers 30 yards from the spot of the kick or at the out-of-bounds spot unless the ball went out-of-bounds the first time an onside kick was attempted. In this case, the kicking team is penalized five yards and the ball must be kicked again.
6. When a kickoff goes out of bounds between the goal lines and is touched last by receiving team, it is the receiver's ball at an out-of-bounds spot.
