1. **Scoring**: Padel Tennis follows a scoring system similar to tennis, with points awarded as 15, 30, 40, and game. However, the game is typically played best out of three sets.

2. **Service**: The serve must be underhand and made from behind the baseline. It must bounce within the service box diagonally opposite the server. The serve must not touch the net and should land in the opponent’s service box.

3. **Serve Order**: The serving team must alternate players for each point and serve diagonally across the court to the opponent’s service box.

4. **Volleys**: Players are allowed to volley (hit the ball before it bounces) both on the serve and during rallies. However, volleys must be made outside the non-volley zone, which extends 3 meters from the net.

5. **Non-Volley Zone**: Also known as the “kitchen” or “no man’s land,” this area prohibits players from volleying the ball while standing inside it. Players can only enter the non-volley zone to hit a ball after it has bounced or if they step in and immediately step out.

6. **Ball in Play**: The ball remains in play as long as it bounces once before being returned. It can bounce off the walls or the fencing surrounding the court and still be in play.

7. **Scoring Points**: Points are won when the opposing team fails to return the ball legally, either by hitting it out of bounds, into the net, or failing to hit it before it bounces twice.

8. **Faults**: Common faults include serving or volleying from within the non-volley zone, failing to let the ball bounce before returning it, touching the net or the opponent’s side of the court with the racket, and obstructing the opponent’s view or movement.

9. **Change of Ends**: Players change ends of the court after every set to account for any differences in court conditions, such as wind or sun.

10. **Let**: In case of a let (a situation where the point is replayed), the serve is retaken without penalty if the ball touches the net and lands in the correct service box.

These are the basic rules of Padel Tennis, providing a framework for fair and competitive play on the court.
