Basketball is a popular sport that can be played at multiple skill levels, from the NBA to the Olympic Games to pickup games at the local gym. The game was invented by Dr. James Naismith in Springfield, Massachusetts, in 1891, and his original rules are publicly displayed at Allen Fieldhouse on the campus of the University of Kansas. Naismith's original rules did not specify how many players should be on the court, but today, the maximum number of players per team on the court is five. Over the years, the rules of basketball have evolved and been updated, including the introduction of dribbling in 1901, the three-second rule in 1936, and the shot clock in 1954. The rules of basketball cover various aspects of the game, including personnel, penalties, and gameplay, and are outlined in rule books such as the NFHS Rules Book, which specifies regulations for court dimensions, equipment specifications, and gameplay guidelines.

What You'll Learn
Substitutions
In the NBA, a substitute must report to the scorer and position themselves in the vicinity of the 8' Substitution Box in front of the scorer's table. They must inform the scorer of who they are replacing, and the scorer will sound the horn to indicate a substitution. A substitute becomes a player when they legally enter the court, and a player becomes bench personnel after their substitute enters the game or after being disqualified.
A player who has been replaced or directed to leave the game cannot re-enter before the next opportunity to substitute after the clock has been started properly. A player who is bleeding, has an open wound, or blood on their uniform or person, must leave the game until the bleeding is stopped, the wound covered, and the uniform and body cleaned. A time-out may be requested to keep a player in the game, which must be granted before the replacement interval begins.

Fouls
Types of Fouls
Personal Fouls: These are infractions that violate the rules of the game and often involve illegal physical contact. Most personal fouls occur when a player impedes an opponent's gameplay through actions like pushing, blocking, or striking. Personal fouls can be called on both players and coaches.
Offensive Fouls: These are personal fouls committed by the team with possession of the ball. Charging and illegal screens are common examples. Charging occurs when an offensive player makes contact with a defensive player who has established a legal guarding position. An illegal screen happens when a non-ball-handling offensive player moves while setting a screen, hindering the defender's movement.
Technical Fouls: These are penalties for violating administrative rules, such as fighting, verbal abuse, or unsportsmanlike conduct. Technical fouls can be called on players, coaches, or anyone on the bench, and they may result in free throws and changes of possession.
Flagrant Fouls: Referees deem these fouls unnecessary or excessive, and they often involve contact that could cause injuries. An FF1 involves unnecessary but not excessive contact, resulting in two free throws and possession for the fouled player. An FF2, deemed more severe, involves both unnecessary and excessive contact and leads to an automatic ejection from the game.
Double Fouls: In some cases, two players from opposing teams may commit fouls simultaneously, resulting in double fouls. These add to individual player foul counts but not the team's count. Double fouls do not result in free throws or turnovers and are resolved through methods like a jump ball or possession arrow, depending on the league.
The accumulation of fouls during a game can lead to player ejections. In the NBA, a player is disqualified after their sixth foul, while lower levels typically allow five fouls. Intentional fouls, or those committed strategically, are permitted in basketball, but excessive fouling can weaken a team through ejections and free points for the opposition.

Dribbling
The basketball rule book has evolved since the game's invention in 1891 and now includes a comprehensive set of rules that govern gameplay, personnel, and penalties. While I cannot confirm the thickness of the rule book, I can provide a detailed overview of the rules pertaining to dribbling.
Players must adhere to specific techniques when dribbling. For instance, when starting a dribble, the ball must leave the player's hand before the pivot foot is raised off the floor. Additionally, a player who has stopped dribbling may not resume dribbling and must instead pass or shoot the ball. This restriction is crucial, as violating it results in a "double dribble" call and the opposing team gaining possession.
The rules also dictate specific limitations on dribbling. For example, a player who runs with the ball without dribbling it commits a violation known as "traveling." Similarly, a player who has voluntarily ended their dribble may not dribble a second time. However, there are exceptions to this rule, such as when a player loses control of the ball due to a field goal attempt or a pass that touches the backboard or basket ring.

Shot clock
The shot clock is a timing device that displays a countdown of the time within which a team must attempt a field goal. The shot clock was first introduced by the NBA in 1954 to increase the speed of play and reduce stalling tactics. Teams were required to attempt a shot within 24 seconds of gaining possession, and the clock would reset when the ball touched the basket's rim or backboard, or if the opponents gained possession.
The introduction of the shot clock was prompted by a game between the Pistons and the Lakers, where the Pistons held the ball for long periods without shooting, limiting the impact of the Lakers' star player, George Mikan. This led to criticism from the media, with the St. Paul Dispatch writing that the Pistons "gave pro basketball a great black eye". NBA President Maurice Podoloff also expressed concern about low-scoring games, stating, "In our game, with the number of stars we have, we of necessity run up big scores."
Following the introduction of the shot clock in the NBA, other basketball organizations around the world adopted similar rules. FIBA, which governs international basketball, adopted a 30-second shot clock in 1956, while women's basketball adopted a 30-second clock in 1971. The NCAA also adopted different shot clock durations for men's and women's basketball, with 45 seconds for men and 30 seconds for women in 1985. Over time, the shot clock duration has been adjusted by various organizations, with the NBA reducing the shot clock to 35 seconds in 1993 and further to 30 seconds in 2015. FIBA also reduced their shot clock to 24 seconds in 2000.
The shot clock rules have also evolved to include specific scenarios and exceptions. For example, if the shot clock buzzer sounds while the ball is in the air after an inadvertent whistle by an official, play is suspended, and a jump ball is used to resume play. Additionally, the shot clock is stopped if a defensive player is the last to touch the ball before it goes out of bounds or enters the basket, and the offensive team is awarded the ball with the remaining time on the shot clock.

Court and equipment
The rules of basketball govern the play, officiating, equipment, and procedures of the game. While many of the basic rules are uniform worldwide, some variations exist. Most leagues or governing bodies in North America formulate their own rules, the most important being the National Basketball Association (NBA) and NCAA. The Technical Commission of the International Basketball Federation (FIBA) determines the rules for international play, and most leagues outside North America follow the complete FIBA ruleset.
The basketball court shall be marked with sidelines, end lines, and other lines. There should be at least 3 feet, and preferably 10 feet, of unobstructed space outside the boundaries. The sidelines and end lines should be a minimum of 2 inches in width. If there is less than 3 feet of space outside any sideline or end line on an unofficial court, a narrow broken line should be marked parallel to and 3 feet inside that boundary. This restraining line becomes the boundary line during a throw-in and remains so until the ball crosses the line. A restraining circle should be drawn at the center of the court with a radius of 6 feet measured to the outside edge.
A division line of 2 inches width shall divide the court into two equal parts. If the court is less than 74 feet long, it should be divided by two lines, each parallel to and 40 feet from the farther end line. Shadow-bordered lines are permissible, with the continuous outline being clearly visible to officials. A three-point line, 2 inches wide in the form of a semicircle, shall be drawn at each end of the court.
The coaching box shall be outlined outside the side of the court where the scorer's and timer's table and team benches are located. The area shall be bounded by a line drawn 28 feet from the end line towards the division line. A line, perpendicular to the 28-foot line and a minimum of 2 feet in length, shall be extended toward the team bench, making the coaching box boundary evident. These lines shall be located off the court and be 2 inches wide.
The time-out area shall be inside an imaginary rectangle formed by the boundaries of the sideline (including the bench), end line, and imaginary lines extended from the free-throw lane line and coaching-box line. The playing of music/sound effects is only permitted during pre-game, time-outs, intermission, and post-game. The use of artificial noisemakers and announcements during the game is prohibited. Electronic devices are permitted during the game, but non-playing personnel must remain outside the playing area during a 30-second time-out.
For NBA games, the backboards must contain four strips of red LED lights, synchronized with the game clock, outlining the inside of the backboard to indicate the expiration of time. There should also be a strip of amber LED light to indicate the expiration of the shot clock. Each basket shall consist of an NBA-approved metal safety ring with a white cord net. The ring should be painted orange, with its upper edge 10 feet above and parallel to the floor, and securely attached to the backboard. The nearest point of the inside edge of the ring should be 6 inches from the plane of the backboard. The cord of the net should be constructed to check the ball momentarily as it passes through the basket.
