Basketball is a team sport played between two teams of five players each, who try to score by shooting a ball through a hoop. The rules of basketball vary depending on the level of play and location, with professional rules differing from college rules, and international rules differing from USA professional rules. However, the basic rules are generally uniform worldwide. Some of the most important rules include dribbling restrictions, foul rules, shot clock restrictions, and rules regarding offensive and defensive play.

Basic rules and interpretations
Basketball is a team sport played between two teams of five players each, who try to score by shooting a ball through a hoop elevated 10 feet above the ground. The game is played on a rectangular floor called the court, with a hoop at each end. The three main sections of the court are the two halves and the mid-court line. If the offensive team puts the ball into play behind the mid-court line, it has ten seconds to get the ball over the line. If it doesn't, the defence gets the ball. Once the offensive team gets the ball over the mid-court line, it can no longer have possession of the ball in the area behind the line.
The team with the ball is called the offence. The team without the ball is called the defence. They try to steal the ball, contest shots, steal and deflect passes, and garner rebounds. The offence must bounce, or dribble, the ball with one hand while moving both feet. If, at any time, both hands touch the ball or the player stops dribbling, the player must only move one foot. The foot that is stationary is called the pivot foot. The player can only take one turn at dribbling. In other words, once a player has stopped dribbling, they cannot start another dribble. A player who starts dribbling again is called for a double-dribbling violation and loses the ball to the other team. A player can only start another dribble after another player from either team touches or gains control of the ball. This is usually after a shot or pass.
The rules of basketball can vary slightly depending on the level of play (for example, professional rules differ from college rules) or where the game is played (international rules are different from USA professional rules). These rule differences, however, are usually just variations on the basic game of basketball, and the majority of the rules can be applied to most games. The winner of a basketball game is the team with the most points. You get points by throwing the basketball through the opponent's hoop or basket. In regular play, a basket made from within the three-point line is worth 2 points and a basket shot from outside the three-point line is worth 3 points. When shooting a free throw, each free throw is worth 1 point. Teams have a limited amount of time to shoot the ball during a given possession. In the NBA and WNBA, teams are allowed 24 seconds of possession before they must shoot, while NCAA teams are allowed 30 seconds.
Fouls are an important part of basketball rules. Fouling a shooter always results in two or three free throws being awarded to the shooter, depending on where they were when they shot. If they were beyond the three-point line, they get three shots. Other types of fouls do not result in free throws being awarded until a certain number have accumulated during a half. Once that number is reached, the player who was fouled is awarded a '1-and-1' opportunity. If they make their first free throw, they get to attempt a second. If they miss the first shot, the ball is live on the rebound. A technical foul can be given when a team calls for more time-outs than they have, delaying the game, have too many players on the court, verbally disrespect or curse, or hang on the rim. With a technical foul, the opposing team is rewarded with a free throw, and possession of the ball as well. If a player or coach gets two technical fouls in one game, it will result in an automatic ejection.

Fouls and violations
Firstly, it's important to understand the difference between a foul and a violation. Every foul is a violation, but not every violation is a foul. Fouls are generally related to player conduct and contact, whereas violations often refer to infringements of time restrictions or game procedures.
Fouls
Fouls are typically called when there is illegal contact between players. This includes impeding an opponent's movement or causing them to lose the ball. The five original fouls, established in 1892, were shouldering, holding, tripping, pushing, and striking. Today, fouls can also include unnatural physical acts without contact, such as throwing an elbow. Offensive fouls occur when the offensive team has possession of the ball, the most common being charging and illegal screens. Charging happens when an offensive player makes contact with a defensive player who is stationary. An illegal screen is when an offensive player moves while setting a screen to block a defender's movement.
Violations
Violations are related to specific actions that break the rules. For example, a shot clock violation occurs when the offense fails to attempt a shot within the allotted time. In the NBA and WNBA, this is 24 seconds, while in college, it is 30 seconds. Another violation is double dribbling, which happens when a player dribbles, stops, and then starts dribbling again without another player touching the ball in between. Players must also be mindful of the three-second rule, which applies to both offensive and defensive players. An offensive player cannot remain in the area between the end line and the free-throw line for more than three seconds while their team has ball control. On the other hand, a defensive player must not stand in the key for more than three seconds without actively guarding an opponent.

Scoring and winning
Basketball is played by two teams of five players each, who compete to score the most points by shooting a ball through a hoop at either end of the court. The team with the most points at the end of the game wins.
Points are accumulated by making field goals (two or three points) or free throws (one point). A field goal refers to any basket scored during gameplay. Field goals can take the form of jump shots, layups, slam dunks, and tip-ins. A basket made from within the three-point line is worth two points, and a basket shot from outside the three-point line is worth three points. When shooting a free throw, each throw is worth one point. Free throws are awarded when an opposition team fouls, or when a team goes "into the bonus", meaning they have exceeded their foul limit for that quarter. In the NBA, teams are allowed five fouls per quarter. After this, the opposing team gets a "double bonus", where they get to take two foul shots.
There are some restrictions on scoring. Teams have a limited amount of time to shoot the ball during a given possession. In the NBA and WNBA, teams are allowed 24 seconds of possession before they must shoot, while NCAA teams are allowed 30 seconds. If the shot clock elapses, the opposing team gets the ball. Players may only advance the ball by passing or dribbling (bouncing the ball on the floor). If a player stops dribbling, they may not resume; they must pass the ball or shoot it. If they start dribbling again, the referee will call a "double dribble", and the opposing team gets the ball.

Time restrictions
Basketball has various time restrictions that players must adhere to. Firstly, teams have a limited amount of time to shoot the ball during a given possession. In the NBA and WNBA, teams have 24 seconds of possession, whereas NCAA teams have 30 seconds. If the shot clock elapses, the opposing team takes possession of the ball.
Additionally, players passing the ball inbounds have five seconds to do so, or the ball is awarded to the other team. Another five-second rule states that a player cannot have the ball for more than five seconds when being closely guarded.
The three-second rule prohibits offensive players from remaining near their opponents' basket for longer than three seconds.
Games are divided into periods, with each team entitled to a certain number of timeouts. In the NBA, each team is allowed seven charged timeouts during regulation play, with a maximum of four timeouts in the fourth period. In overtime periods, each team is allowed two timeouts.
The duration of each period and the number of timeouts allowed can vary depending on the league and level of play. For example, a game may consist of four quarters of nine minutes each, with one minute between quarters and three minutes between halves. Alternatively, it could be two halves of 20 minutes each, with a running clock and a one-minute break in between.
The timing rules can also change depending on the situation. For instance, the clock will stop for injuries and officials' timeouts but not for fouls, held balls, or violations (unless there are less than two minutes remaining in the second half or less than one minute remaining in overtime).
Finally, there is the "mercy rule", which comes into effect if the point differential reaches 50 points at any time during the game or 30 points with less than five minutes remaining.

Player positions and substitutions
Basketball is a team sport with five players on the court for each team at any one time. Each player is assigned to a different position, defined by the strategic role they play. The three main position categories are guard, forward, and center. The standard team features two guards, two forwards, and a center.
The guards are typically called the "back court" and the forwards and centers the "front court". Over time, as more specialized roles developed, each of the guards and forwards came to be differentiated. Today, each of the five positions is known by a unique name and number: point guard (PG) or 1, shooting guard (SG) or 2, small forward (SF) or 3, power forward (PF) or 4, and center (C) or 5.
The point guard is basketball's "quarterback", setting the team's pace on offense and defense. They are the tactical masterminds of the basketball court, with a high basketball IQ, the ability to see the floor, and creative passing skills. They also need quick hands and strong ball-handling skills. On offense, point guards are responsible for bringing the ball up the court and facilitating the plays. Some point guards are known for their defensive skills and their ability to impact the offense of opposing teams' forwards and centers, despite their smaller size.
The shooting guard, also known as the two or the off guard, is, along with the small forward, often referred to as a wing because of its use in common positioning tactics. Most shooting guards are prolific from the three-point range and long mid-range. Their ability to correctly space the floor and find open space for themselves is a key aspect of this position.
The small forward, also known as the three, is considered to be the most versatile of the main five basketball positions. Versatility is key for small forwards due to the nature of their role, which resembles that of a shooting guard more often than that of a power forward. This is why the small forward and shooting guard positions are often used interchangeably and referred to as wings. This position is like the "Swiss army knife" because they can do just about everything, from scoring, to rebounding, handling the ball, passing, and the ability to defend, if they are a skilled small forward.
The power forward, also known as the four, is usually the second tallest in the team, and the closest to the center in terms of physical attributes and playing style, but with more speed. They are often the most versatile player on the court, being able to shoot from a range of distances, and can take longer shots than centers. It is a physical position that requires a large amount of strength to guard bigger players close to the basket, and power forwards are often known for their ability to win the ball as well as blocking shots.
The center, also known as the five, plays near the basket in the low post area on offense. They are often one of the taller players, but they need to be agile and have strong post moves. Key skills for centers are size, strength, rebounding, and finishing at the rim. On offense, they are available to score short-range shots or layups. On defense, their size can help them to take up space in the paint, allowing them to block shots and grab rebounds.
In addition to these five positions, there are two more unofficial positions. The sixth man is a versatile player that can fill several positions as needed. They start the game on the bench and are usually the first player to substitute in, bringing energy and a spark to the lineup. The other unofficial position is the combo guard, a player with the skills and abilities of both a point guard and a shooting guard.
Substitutions are important in basketball as they allow teams to keep players fresh and adapt to different situations in the game. Basketball is fast-paced, and players can get tired quickly, so substitutes come in to give starters a rest and bring new energy to the game. Coaches use substitutions to manage fatigue, ensuring players don't get too tired and can avoid injuries.
In the NBA, teams can have up to 15 players, but only 13 can be active for a game. This means two players are inactive and cannot play in that game. Coaches decide who will be active based on strategy, injuries, and player performance. In FIBA International Play, teams can have up to 12 players for tournaments, and all 12 players can be active and play in the games.
