Pickleball is played either as doubles (two players per team) or singles; doubles is most common
The same size playing area and rules are used for both singles and doubles
The Serve
The server’s arm must be moving in an upward arc when the ball is struck.
Paddle contact with the ball must not be made above the waist level.
The head of the paddle must not be above the highest part of the wrist at contact.
A ‘drop serve’ is also permitted in which case none of the elements above apply.
At the time the ball is struck, the server’s feet may not touch the court or outside the imaginary extension of the sideline or centerline and at least one foot must be behind the baseline on the playing surface or the ground behind the baseline.
The serve is made diagonally cross-court and must land within the confines of the opposite diagonal court.
Only one serve attempt is allowed per server.
Serving Sequence
Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).
The first serve of each side-out is made from the right/even court.
If a point is scored, the server switches sides and the server initiates the next serve from the left/odd court.
As subsequent points are scored, the server continues switching back and forth until a fault is committed, and the first server loses the serve.
When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).
The second server continues serving until his team commits a fault and loses the serve to the opposing team.
Once the service goes to the opposition (at side out), the first serve is from the right/even court and both players on that team have the opportunity to serve and score points until their team commits two faults.
In singles the server serves from the right/even court when his or her score is even and from the left/odd when the score is odd.
*At the beginning of each new game only one partner on the serving team has the opportunity to serve before faulting, after which the service passes to the receiving team.
Scoring
Points are scored only by the serving team.
Games are normally played to 11 points, win by 2.
Tournament games may be to 15 or 21, win by 2.
When the serving team’s score is even (0, 2, 4, 6, 8, 10) the player who was the first server in the game for that team will be in the right/even court when serving or receiving; when odd (1, 3, 5, 7, 9) that player will be in the left/odd court when serving or receiving.
Two-Bounce Rule
When the ball is served, the receiving team must let it bounce before returning, and then the serving team must let it bounce before returning, thus two bounces.
After the ball has bounced once in each team’s court, both teams may either volley the ball (hit the ball before it bounces) or play it off a bounce (ground stroke).
The two-bounce rule eliminates the serve and volley advantage and extends rallies.
Line Calls
A ball contacting any part of any line, except the non-volley zone line on a serve, is considered “in.”
A serve contacting the non-volley zone line is short and a fault.
Non-Volley Zone
The non-volley zone is the court area within 7 feet on both sides of the net.
Volleying is prohibited within the non-volley zone. This rule prevents players from executing smashes from a position within the zone.
It is a fault if, when volleying a ball, the player steps on the non-volley zone, including the line and/or when the player’s momentum causes them or anything they are wearing or carrying to touch the non-volley zone including the associated lines.
It is a fault if, after volleying, a player is carried by momentum into or touches the non-volley zone, even if the volleyed ball is declared dead before this happens.
A player may legally be in the non-volley zone any time other than when volleying a ball.
The non-volley zone is commonly referred to as “the kitchen.”
Faults
A fault is any action that stops play because of a rule violation.
A fault by the receiving team results in a point for the serving team.
A fault by the serving team results in the server’s loss of serve or side out.
Determining Serving Team
Any fair method can be used to determine which player or team has first choice of side, service, or receive. (Example: coin flip)

The object of badminton is to hit the shuttlecock over the net and have it land in the designated court areas. If your opponent manages to return the shuttlecock then a rally occurs. If you win this rally i.e. force your opponent to hit the shuttlecock out or into the net then you win a point. You are required to win 21 points to win a set with most matches being best of 3 sets. Points can be won on either serve.
A game can take place with either two (singles) or four (doubles) players.
An official match has to be played indoors on the proper court dimensions. The dimensions are 6.1m by 13.4m, The net is situated through the middle of the court and is set at 1.55m.
To score a point the shuttlecock must hit within the parameters of the opponents court.
If the shuttlecock hits the net or lands out then a point is awarded to your opponent.
Players must serve diagonally across the net to their opponent. As points are won then serving stations move from one side to the other. There are no second serves so if your first serve goes out then your opponent wins the point.
A serve must be hit underarm and below the servers waist. No overarm serves are allowed.
Each game will start with a toss to determine which player will serve first and which side of the court the opponent would like to start from.
Once the shuttlecock is ‘live’ then a player may move around the court as they wish. They are permitted to hit the shuttlecock from out of the playing area.
If a player touches the net with any part of their body or racket then it is deemed a fault and their opponent receives the point.
A fault is also called if a player deliberately distracts their opponent, the shuttlecock is caught in the racket then flung, the shuttlecock is hit twice or if the player continues to infract with the laws of badminton.
Each game is umpired by a referee on a high chair who overlooks the game. There are also line judges who monitor if the shuttlecock lands in or not. The referee has overriding calls on infringements and faults.
Let may be called by the referee if an unforeseen or accidental circumstance arose. These may include the shuttlecock getting stuck in the bet, server serving out of turn, one player was not ready or a decision which is too close to call.
The game has only two rest periods coming the form of a 90 second rest after the first game and a 5 minute rest period after the second game.
If the laws are continuously broken by a player then the referee holds the power to dock that player of points with persisting fouls receiving a forfeit of the set or even the match.
There are two forms of badminton, singles and doubles (it’s also possible to play mixed doubles). Each player is allowed to use a stringed racket (similar to a tennis racket but with the head being smaller) and a shuttlecock. The shuttlecock is made up of half round ball at the bottom and a feather like material surrounding the top. You can only really hit the bottom of the shuttlecock and as gravity comes into play will always revert the ball side facing down. You may only hit the shuttlecock once before it either hits the ground or goes over the net.
The court measures 6.1m wide and 13.4m long. Across the middle of the rectangular court is a net which runs at 1.55m. Running along each side of the court are two tram lines. The inside lines are used as the parameter for singles match whilst the outside line is used for a doubles match.
A point is scored when you successfully hit the shuttlecock over the net and land it in your opponent’s court before they hit it. A point can also be gained when your opponent hits the shuttlecock into either the net or outside the parameters.
To win a game you must reach 21 points before your opponent. If you do so then you will have won that set. If the scores are tied at 20-20 then it comes down to whichever player manages to get two clear points ahead. If the points are still tied at 29-29 then the next point will decide the winner of the set. Winning the overall game will require you to win 2 out of the 3 sets played.
