Basketball is a sport with a rich history that dates back to the late 19th century. Created by Dr. James Naismith in 1891, the original 13 rules of basketball were published in January 1892 and formed the foundation of the game we know and love today. While some rules have evolved, such as the use of hoops and nets instead of baskets, the core principles remain intact, with fouls, ball handling, and scoring mechanics still reflecting Naismith's original vision. These rules have been adapted and refined over time, with different leagues and governing bodies introducing variations, but the enduring popularity of basketball is a testament to the solid framework established by those initial 13 rules.

What You'll Learn
Game length and overtime
The length of a basketball game and its overtime periods can vary depending on the league and level of play. In the National Basketball Association (NBA), a game is played in four quarters, each lasting 12 minutes, with a 15-minute halftime break. This means the normal duration of an NBA game is 48 minutes, excluding any overtime.
At the collegiate level, the game is often divided into two halves of 15 minutes each, with a 5-minute rest period in between. This results in a standard game time of 20 minutes, excluding overtime.
If the score is tied at the end of the regulation period in the NBA, the game goes into overtime. Overtime periods in the NBA are typically 5 minutes long, and this duration is consistent across various levels of play, including collegiate basketball.
During overtime, the game clock is stopped during the last two minutes after a successful field goal attempt. Additionally, certain rules, such as the "mercy rule," may come into effect to expedite the game's conclusion if the point differential reaches a certain threshold.
In the case of a persistent tie, the game may continue into multiple overtime periods until a winner is determined. This scenario has occurred in NBA history, with some games requiring up to six overtime periods to decide a winner.
It's worth noting that in 3x3 basketball, a formalized half-court three-on-three game, overtime is handled differently. Ties after a 10-minute game are resolved by continuing play with only a shot clock and no game clock. The first team to score two additional points wins, and the 21-point rule does not apply during this extra period.

Fouls and disqualifications
Today, a foul is an infraction of the rules, often resulting from illegal personal contact or unsportsmanlike behaviour. There are several classes of fouls, including personal fouls, which are the most common, and flagrant fouls, which involve violent or unnecessary contact. Personal fouls can be further categorised as offensive fouls (by the team with ball possession) or loose-ball fouls (when neither team has clear possession).
The consequences of committing a foul can vary. The fouled player's team may gain possession of the ball, and the player may be awarded one or more free throws. The player committing the foul may be penalised, sometimes resulting in disqualification or suspension from subsequent games. The number of fouls permitted before disqualification varies depending on the league and game length. For instance, in a 40-minute game, a player who commits five personal fouls is disqualified, whereas in a 48-minute game, six fouls are permitted before disqualification.
Some specific fouls and their consequences are outlined in the official rules of leagues such as the NBA. For example, a defensive player hanging on their opponent's basket ring or net is assessed a non-unsportsmanlike technical foul. Additionally, the NBA introduced the "coach's challenge," allowing teams to challenge personal foul calls on their players during specific game periods.
In FIBA-authorised 3x3 half-court competitions, players cannot foul out as personal foul counts are kept on a team basis. However, unsportsmanlike and disqualifying fouls are assessed to individuals, and committing two unsportsmanlike fouls or one disqualifying foul results in removal from the game.
Fouls and their consequences are an essential aspect of basketball, helping to maintain fair play and sportsmanship while also adding strategic depth to the game.

Ball possession
Basketball, invented by Dr. James Naismith in 1891, has undergone several changes since its inception. The original game played under the first set of rules was quite different from the one played today. For instance, there was no dribbling, dunking, three-pointers, or shot clock, and goal tending was legal. The ball could be thrown in any direction with one or both hands.
The referee is the judge of the ball and decides when it is in play, in bounds, and to which side it belongs. They also keep the time and determine when a goal has been made. The game is divided into halves or quarters, with a set number of minutes for each, and the side that makes the most goals in that time is the winner.
The first time restriction on ball possession was introduced in 1933, requiring teams to advance the ball past the center line within 10 seconds of gaining possession. FIBA reduced this time to eight seconds in 2000, followed by the NBA in 2001. The NCAA retains the 10-second rule for men's basketball and adopted it for women starting in the 2013-2014 season.
Additionally, when a team is inbounding the basketball, they have 5 seconds to do so, regardless of their position on the court. If they fail to release the ball within this time, it results in a turnover, and possession goes to the opposing team.
Another important rule regarding ball possession is the three-second rule, introduced in 1936, which prohibits offensive players from lingering near their opponents' basket for more than three seconds. This rule was initially implemented to reduce roughness between players but now serves to prevent tall offensive players from gaining an advantage by waiting close to the basket.
The shot clock was introduced by the NBA in 1954 to increase the pace of the game. Teams must attempt a shot within 24 seconds of gaining possession, and the clock resets when the ball makes contact with the basket's rim or backboard or when the opposing team gains possession. FIBA, women's basketball, and the NCAA adopted longer shot clock durations of 30 seconds, 45 seconds for men, and 30 seconds for women, respectively.

The role of the referee
During the game, referees are responsible for keeping time and determining when a goal has been made, as well as keeping a running tally of goals scored. They must also be aware of the level of contact and roughness of play across the entire court, as basketball is a sport that allows for a certain level of incidental contact. Referees are also tasked with managing the players and spectators, and have the authority to remove a disruptive fan from the arena.
In the NBA, there are typically three referees, one of whom is designated as the crew chief. The crew chief has the authority to set aside or question decisions made by the other referees. In addition to the referees, there are two trained timers, one operating the game clock and the other the shot clock, and a courtside administrator who facilitates communication between officials and personnel at the scorer's table. At higher levels of basketball, officials also wear a Precision Timing System (PTS) device on their belt to start and stop the game clock.
Overall, the referee plays a critical role in ensuring the smooth and fair running of a basketball game, and their duties extend beyond simply enforcing the rules to include a range of responsibilities before, during, and potentially after the game.

Scoring a goal
Basketball is a sport with a rich history that dates back to the game's invention by Dr. James Naismith over a century ago. While the rules have evolved, the original 13 rules laid the foundation for the game we know and love today. One of the most crucial aspects of basketball is scoring, so let's delve into the rules surrounding scoring a goal.
The essence of basketball lies in scoring goals, and according to the original rules, a goal is achieved when the ball is successfully "thrown or batted from the grounds into the basket and stays there." This rule underscores the importance of accurate shooting and ball control. It's worth noting that the original game did not involve dribbling or dunking, so players relied solely on their passing and shooting skills to score.
Ensuring fair play, the rules also specify that defenders cannot touch or disturb the goal when the ball is in it. If the ball rests on the edges of the basket and an opponent moves the basket, it is still considered a goal. This rule prevents defenders from interfering with a legitimate shot that has a high probability of scoring.
To promote sportsmanship and safety, unsportsmanlike behaviors such as shouldering, holding, pushing, tripping, or striking an opponent are strictly prohibited. These actions are considered fouls, and the consequences are outlined in the rules. If a player commits a foul, it can result in a free throw for the fouled player's team or even disqualification for the player, depending on the severity and the number of fouls committed.
The rules also address the scenario of the ball going out of bounds. In such cases, the ball must be promptly thrown back into the field of play by the person who first touched it. If a team delays this process, the umpire is authorized to call a foul on that team. This rule ensures a smooth and uninterrupted flow to the game.
Finally, the original rules established the duration of a basketball game. It consisted of two fifteen-minute halves, with a five-minute rest period in between. The team with the most goals at the end of the allotted time is declared the winner. In the event of a draw, the game could be extended by mutual agreement until another goal is scored, ensuring a decisive outcome.
Over time, the rules of basketball have evolved to enhance the sport's excitement and fairness. Governing bodies like the National Basketball Association (NBA), NCAA, and the International Basketball Federation (FIBA) continue to refine the rules to meet the needs of the modern game. While some rules have been added or modified, the original 13 rules, including the guidelines for scoring a goal, remain at the heart of basketball's enduring appeal.

Frequently asked questions
The original 13 rules of basketball were written and published by Dr. James Naismith in 1891 while he was working for the YMCA. The rules were first published in January 1892 in a school newspaper called The Triangle.
Some of the original 13 rules of basketball include:
- The ball may be thrown in any direction with one or both hands.
- Players cannot run with the ball and must throw it from the spot they catch it.
- No shouldering, holding, pushing, tripping, or striking of an opponent is allowed.
- The referee shall be the judge of the ball and shall decide when the ball is in play, in bounds, and to which side it belongs.
- The time shall be two 15-minute halves, with 5 minutes of rest in between.
While many of the original 13 rules still form the heart of the game, there have been some changes and additions over the years. For example, the game now uses hoops and nets instead of baskets, and there are rules for dribbling, dunking, three-pointers, and shot clocks. The rules regarding fouls and disqualifications have also evolved, with players now receiving ejections or suspensions for major fouls.
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. Within North America, various leagues and governing bodies formulate their own rules, with the National Basketball Association (NBA) and NCAA being the most influential.
Some specific rule changes include the introduction of a shot clock by the NBA in 1954 to increase the speed of play, the adoption of a three-second rule for offensive players in 1936 to prevent rough play near the basket, and adjustments to the time limit for possession of the ball, which was reduced from 10 seconds to 8 seconds by FIBA in 2000.
