The rules of badminton include: 
1. The shuttlecock must be hit by the racquet over the net.
2. It must pass over the net, within the boundaries of the court.
3. Players can only hit the shuttlecock once before it passes over the net.
4. Scoring is done on a rally point system, with games usually played up to 21 points.
5. The side that reaches 21 points first, with a minimum lead of two, is declared the winner.
6. Service switches after every point and every game.
7. Picking up and carrying the shuttlecock is not allowed.
8. If the shuttlecock touches the ceiling or any other object, the side who hit the shuttlecock loses the point.
