Squash is a racket and ball sport played by two players in a four-walled court with a small, hollow rubber ball. The players alternate in striking the ball with their rackets onto the playable surfaces of the four walls of the court.

Squash appears similar to another sport in The World Games programme, i.e. Racquetball. Main differences between the two sports concern the ball, racket and court dimensions. An important distinction between the rules of Squash and Racquetball is the use of a ceiling as a playing surface, which is allowed in Racquetball but not allowed in Squash.

Squash can be played in singles, doubles and teams.

The objective of the game is to hit the ball in such a way that the opponent is not able to play a valid return, and therefore to score a point.

- Double Elimination Draw (i.e. knockout rounds) format will be used.

- Winning athletes qualify for the next rounds until they reach the finals.

- Athletes who lose in the first round will compete in a plate draw for the 17th place.

- Losing semi-finalists compete for Bronze.

- Finalists compete for Gold and Silver.

- Matches from Round 1 to Quarter Finals will be Best of 3 Games.

- Matches from Semifinals to Finals will be Best of 5 Games.

Players start the first rally by electing to serve from either the left or right service box. After the serve, the players take turns hitting the ball against the front wall, above the tin and below the outline. If the server wins the point, the two players switch sides for the following point. If the server loses the point, the opponent then serves, and can serve from either box.

The ball may strike the side or back walls at any time, as long as it hits below the outline. It must not hit the floor after hitting the racket and before hitting the front wall. A ball landing on either the outline or the line along the top of the tin is considered to be out.

After the ball hits the front wall, it is allowed to bounce once on the floor - and any number of times against the side or back walls - before a player must return it.

Players may move anywhere around the court. Accidental or deliberate obstruction of the other player's movements is forbidden and could result in a let or a stroke. Players typically return to the centre of the court after making a shot.

A common tactic is to hit the ball straight up the side walls to the back corners; this is the basic squash shot, referred to as a "rail," straight drive, wall, or "length". After hitting this shot, the player will then move to the centre of the court near the "T" to be well-placed to retrieve the opponent's return.

Attacking with soft or "short" shots to the front corners (referred to as "drop shots") causes the opponent to cover more of the court and may result in an outright winner. Boasts or angle shots are deliberately struck off one of the side walls before the ball reaches the front. They are used for deception and again to cause the opponent to cover more of the court. Rear wall shots float to the front either straight or diagonally, drawing the opponent to the front. Advantageous tactical shots are available in response to a weak return by the opponent if stretched, the majority of the court being free to the striker.

For a legal serve, one of the server's feet must be in the service box, not touching any part of the service box lines, as the player strikes the ball. After being struck by the racket, the ball must strike the front wall above the service line and below the outline and land in the opposite back quarter court. The receiving player can choose to volley a serve after it has hit the front wall. If the server wins the point, the two players switch sides for the following point. If the server loses the point, the opponent then serves, and can serve from either box.

Coaching is considered to be communication, advice or instruction of any kind and by any means to a player, and during matches is only permitted in the intervals between games.

Interference and obstruction are an inevitable aspect of squash, since two players are confined within a shared space. Generally, the rules entitle players to a direct straight line access to the ball, room for a reasonable swing and an unobstructed shot to any part of the front wall.

When interference occurs, a player may appeal for a "let" and the referee then interprets the extent of the interference. The referee may allow a let and the players then replay the point, or award a "stroke" to the appealing player (meaning that he is declared the winner of that point). This depends on the degree of interference, whether the interfering player made an adequate effort to avoid interfering, and whether the player interfered with was likely to have hit a winning shot had the interference not occurred.

An exception occurs when the interfering player is directly in the path of the other player's swing, effectively preventing the swing, in which case a stroke is always awarded.

When it is deemed that there has been little or no interference, the rules provide that no let is to be allowed in the interests of continuity of play and the discouraging of spurious appeals for lets. Because of the subjectivity in interpreting the nature and magnitude of interference, awarding (or withholding) of lets and strokes is often controversial.

Each game is played to 11 points. If the score reaches 10-all, the game continues until one player leads by two points.

The matches will be played best of three games up to quarter finals and best of five games from the semifinals to the finals. The first player to win three games wins the match.

Code of Conduct problems on court will be dealt with by the referee who can issue a warning, or deduct a stroke, award a game against a player or in the most extreme circumstances award a match against a player.

A player may also be disqualified, and the player awarded a walkover if they are not on court ready to play within 15 minutes of the published start time of the match or within 15 minutes of the finish of the preceding match, if later.
