=== Starting a game ===
According to ITTF rule 2.13.1, the first service is decided by lot,<ref name=ITTF2.13.1>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.13.1}}</ref> normally a [[coin toss]].<ref name="match officials">{{cite web |title=ITTF Handbook for Match Officials 13th edition |date=August 2007 |publisher=ITTF |url=http://www.ittf.com/ITTF_Misc/Comittees/Handbook%20for_Match_Officials_13th_edition.pdf |access-date=1 September 2010 |url-status=dead |archive-url=https://web.archive.org/web/20120405171806/http://www.ittf.com/ITTF_Misc/Comittees/Handbook%20for_Match_Officials_13th_edition.pdf |archive-date=5 April 2012}}</ref> It is also common for one player (or the umpire/scorer) to hide the ball in one or the other hand, usually hidden under the table, allowing the other player to guess which hand the ball is in. The correct or incorrect guess gives the "winner" the option to choose to serve, receive, or to choose which side of the table to use. (A common but non-sanctioned method is for the players to play the ball back and forth three times and then play out the point. This is commonly referred to as "serve to play", "rally to serve", "play for serve", or "volley for serve". Another common method is referred to as "Ping for serve" or "Pinging for serve" where players will begin playing by hitting or bouncing the ball and playing a rally spelling out the word ping P-I-N-G with each hit then playing out the point for service).

=== Service and return ===

In game play, the player serving the ball commences a play.<ref name=ITTF2.5>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.5}}</ref> The server first stands with the ball held on the open palm of the hand not carrying the paddle, called the freehand, and tosses the ball directly upward without spin, at least {{convert|16|cm|1|abbr=on}} high.<ref name=ITTF2.6>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.6}}</ref> The server strikes the ball with the racket on the ball's descent so that it first touches the server's court, and then touches directly the receiver's court without touching the net assembly. In casual games, many players do not toss the ball upward; however, this is technically illegal and can give the serving player an unfair advantage.<ref name=RacketInsight>{{cite web|url=https://racketinsight.com/table-tennis/serving-rules-in-table-tennis/|title=The 5 Serving Rules in Table Tennis You Need to Know|first1=Álvaro|last1=Munno|first2=David|last2=Bruce|date=15 January 2022 |access-date=6 October 2023}}</ref>

The ball must remain behind the endline and above the playing surface of the table at all times during the service. The server's body or clothing cannot be used to obstruct sight of the ball; the opponent and the umpire must have a clear view of the ball at all times. If the umpire is doubtful of the legality of a service they may first interrupt play and give a warning to the server. If the serve is a clear failure or is doubted again by the umpire after the warning, the receiver scores a point.

If the service is "good", then the receiver must make a "good" return by hitting the ball back before it bounces a second time on receiver's side of the table so that the ball passes the net and touches the opponent's court, either directly or after touching the net assembly.<ref name=ITTF2.7>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.7}}</ref> Thereafter, the server and receiver must alternately make a return until the rally is over. Returning the serve is one of the most difficult parts of the game, as the server's first move is often the least predictable and thus most advantageous shot due to the numerous spin and speed choices at the server's disposal.

=== Let ===
A let is a rally of which the result is not scored, and is called in the following circumstances:<ref name=ITTF2.5.3>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.5.3 and 2.9}}</ref>

* The ball touches the net in service (service), provided the service is otherwise correct or the ball is obstructed by the player on the receiving side. Obstruction means a player touches the ball when it is above or traveling towards the playing surface, not having touched the player's court since last being struck by the player.
* When the player on the receiving side is not ready and the service is delivered.
* Player's failure to make a service or a return or to comply with the Laws is due to a disturbance outside the control of the player.
* Play is interrupted by the umpire or assistant umpire.

A let is also called foul service, if the ball hits the server's side of the table, if the ball does not pass further than the edge, and if the ball hits the table edge and hits the net.

=== Scoring ===
[[File:Table tennis umpire.jpg|thumb|Table tennis umpire]]
A point is scored by the player for any of several results of the rally:<ref name=ITTF2.5.4>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.5.4 and 2.10}}</ref>

* The opponent fails to make a correct service or return.
* After making a service or a return, the ball touches anything other than the net assembly before being struck by the opponent.
* The ball passes over the player's court or beyond their end line without touching their court, after being struck by the opponent.
* The opponent obstructs the ball.
* The opponent strikes the ball twice successively. The hand that is holding the racket counts as part of the racket and that making a good return off one's hand or fingers is allowed. It is not a fault if the ball accidentally hits one's hand or fingers and then subsequently hits the racket.
* The opponent strikes the ball with a side of the racket blade whose surface is not covered with rubber.
* The opponent moves the playing surface or touches the net assembly.
* The opponent's free hand touches the playing surface.
* As a receiver under the expedite system, completing 13 returns in a rally.<ref name=ITTF2.15>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.15}}</ref>
* The opponent that has been warned by the umpire commits a second offense in the same individual match or team match. If the third offence happens, 2 points will be given to the player.<ref name=ITTF3.5.2>{{Harvnb|International Table Tennis Federation|2011| loc=index 3.5.2}}</ref> If the individual match or the team match has not ended, any unused penalty points can be transferred to the next game of that match.<ref name="match officials"/>

A game shall be won by the player first scoring 11 points unless both players score 10 points, when the game shall be won by the first player subsequently gaining a lead of 2 points. A match shall consist of the best of any odd number of games.<ref name=ITTF2.11>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.11 and 2.12}}</ref> In competition play, matches are typically best of five or seven games.

=== Alternation of services and ends ===
Service alternates between opponents every two points (regardless of winner of the rally) until the end of the game, unless both players score ten points or the expedite system is operated, when the sequences of serving and receiving stay the same but each player serves for only one point in turn (Deuce).<ref name=ITTF2.13>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.13 and 2.14}}</ref> The player serving first in a game receives first in the next game of the match.

After each game, players switch sides of the table. In the last possible game of a match, for example the seventh game in a best of seven match, players change ends when the first player scores five points, regardless of whose turn it is to serve. If the sequence of serving and receiving is out of turn or the ends are not changed, points scored in the wrong situation are still calculated and the game shall be resumed with the order at the score that has been reached.

=== Doubles game ===

In addition to games between individual players, pairs may also play table tennis. Singles and doubles are both played in international competition, including the Olympic Games since 1988 and the [[Commonwealth Games]] since 2002.<ref>{{cite web |url=http://www.ittf.com/ittf_stats/stats_by_event.htm |title=ITTF statistics by event |publisher=ITTF |access-date=1 September 2010 |url-status=dead |archive-url=https://web.archive.org/web/20100831230024/http://www.ittf.com/ittf_stats/stats_by_event.htm |archive-date=31 August 2010}}</ref>

In doubles, all the rules of single play are applied except for the following.

'''Service'''
: A line painted along the long axis of the table to create doubles courts bisects the table. This line's only purpose is to facilitate the doubles service rule, which is that service must originate from the right hand "box" in such a way that the first bounce of the serve bounces once in said right hand box and then must bounce at least once in the opponent side's right hand box (far left box for server), or the receiving pair score a point.<ref name=ITTF2.6/>

'''Order of play, serving and receiving'''
# Players must hit the ball in turn. For example, if A is paired with B and X is paired with Y, then A is the server and X is the receiver. and the order of play shall be A→X→B→Y. The rally proceeds this way until one side fails to make a legal return and the other side scores.<ref name=ITTF2.8>{{Harvnb|International Table Tennis Federation|2011| loc=index 2.8}}</ref>
# At each change of service, the previous receiver shall become the server and the partner of the previous server shall become the receiver. For example, if the previous order of play is A→X→B→Y, the order becomes X→B→Y→A after the change of service.<ref name=ITTF2.13/>
# In the second or the latter games of a match, the game begins in reverse order of play. For example, if the order of play is A→X→B→Y at beginning of the first game, the order begins with X→A→Y→B or Y→B→X→A in the second game depending on either X or Y being chosen as the first server of the game. That means the first receiver of the game is the player who served to the first server of the game in the preceding game. In each game of a doubles match, the pair having the right to serve first shall choose which of them will do so. The receiving pair, however, can only choose in the first game of the match.
# When a pair reaches 5 points in the final game, the pairs must switch ends of the table and change the receiver to reverse the order of play. For example, when the last order of play before a pair score 5 points in the final game is A→X→B→Y, the order after change shall be A→Y→B→X if A still has the second serve. Otherwise, X is the next server and the order becomes X→A→Y→B.

=== Expedite system ===
If a game is unfinished after 10 minutes of play and fewer than 18 points have been scored, the expedite system is initiated.<ref name="ITTF2.15"/> The umpire interrupts the game, and the game resumes with players serving for one point in turn. If the expedite system is introduced while the ball is not in play, the previous receiver shall serve first. Under the expedite system, the server must win the point before the opponent makes 13 consecutive returns or the point goes to the opponent. The system can also be initiated at any time at the request of both players or pairs. Once introduced, the expedite system remains in force until the end of the match. As it is intended as a rule to shorten the duration of a match, it is mainly deployed in defensive players' matches, which tend to have longer points.
