Three Rules

Article 3

3-1 Number of Athletes: Both sides of the game can register 4~5 people, and the players on the court are three.

3-2 Duration of the match:

3-2-1 The preliminary rounds and the repechage are not divided into upper and lower halves, and the duration of the whole match is 10 minutes (the organizer may revise the time to 12 or 15 minutes according to the number of teams). When the match reaches the 5-minute and 9-minute mark, the recorder announces the time once each. If there are only 10 minutes to play, neither team may take a time-out (the referee has the right to pause the game for 1 minute in case of injury). If the match is scheduled for 12 or 15 minutes, one or two time-outs of 30 seconds each are allowed.

3-2-2 The final is divided into two halves of 8 minutes each, with a 3-minute break between the first and second halves.

3-2-3 The clock is not stopped during the game except in the case of penalties, time-outs, player injuries and the end of the game.

Article 4

4-1 START OF MATCH: The teams will decide on the right to serve by a coin toss, and then start the match by tossing an out-of-bounds ball in the serving area.

In the final phase, the team that has been awarded the serve in the first half of the match is no longer awarded the serve in the second half, and the opposing team starts the match by throwing an out-of-bounds ball on the tee.

4-2 Tee-off area: The semicircle in which the center circle is not in the field is called the tee-off area, and the ground (including the line) in the tee-off area is considered out-of-bounds.

4-3 Serve: Throwing the ball out of bounds in the serving area counts as a serve.

Article V

5-1 Offensive Conversion:

5-1-1 After each shot is hit, the opposing team serves the ball.

5-1-2 All exchanges of serves (e.g., after infractions, out-of-bounds, and after a shot is hit) are dead balls, and play continues with an out-of-bounds throw in the serving area.

All situations where the serve is not exchanged (e.g., fouls where free throws are not enforced), the ball is served from the nearest three-point line. In this case, the ball must be submitted by the referee before serving.

5-1-3 After a defending player breaks the ball or grabs a rebound, he must carry (pass) the ball beyond the three-point line (the player with the ball must have both feet outside the three-point line) before organizing an offense, or an offensive violation will be ruled.

5-1-4 During a scrimmage, the ball is jumped at the free-throw circle, and the ball must be carried (passed) out to the three-point line (the player with the ball must have both feet outside the three-point line) before an offense can be organized, or an offensive violation will be ruled. If the ball is accidentally thrown in the jump ball, the ball will be re-jumped.

Whenever there is a violation involving the 5-1-3 and 5-1-4, the referee's hand signal is: cross both forearms in front of the face to indicate the violation and exchange the serve. (This gesture is the same as the exchange of serve gesture. My drawing skills are not up to it, so I won't draw it; the original article has an illustration of this gesture. hkmj note).

Article VI

6-1 20-second rule: The 24-second rule is changed to 20 seconds

6-2 Fouls Rule:

6-2-1 Three fouls are allowed for each player in the game, with a fourth foul being sent off.

6-2-2 Any player awarded a disqualifying foul disqualifies the team from the game.

6-2-3 After each team has accrued five fouls, the opposing team shall execute two free throws for that team's sixth subsequent encroachment foul. In the first 5 fouls, any foul on the player who is doing the shooting action: if the shot is won, record the score, the number of opposing personal and team fouls, no additional free throws, the defending team will serve the ball to continue the game; if the shot is not won, then awarded to the attacking side of the infringed player 1 free throws, such as free throws won the score of 1, and the attacking side to continue to throw in-bounds, such as the free throws won't be won, and the attacking side to continue to throw the ball out of bounds.

6-2-4 In games where a mini-basket is used, a player is not allowed to have a dunking maneuver, nor is a player allowed to hang any part of his body from the rim or basket, or he may be penalized by being sent off the court and not being replaced on the court again, and the team loses possession of the ball.

Rule 7

7-1 Substitutions: Substitutions may only be made when the game clock has been stopped, and the substituted player may not be substituted again (except when there are fewer than three players on the court).

Article VIII

8-1 Equalization of Scores and Tiebreaker Periods:

The winner is the one who has scored more points at the end of the game time. In the preliminary and repechage stages, at the end of the game time, if the scores are equal, one-to-one sequential free throws will be executed, and as long as there is a one-point lead for a team, the winner will be the winner and the game will be over.

In the final stage, at the end of the game, if the scores are equal, a 3-minute tie-breaker period will be added, and the right to serve will still be decided by a coin toss. If the scores are still equal in the tie-breaking period, one-on-one sequential free throws will be executed, and as long as there is a one-point lead for a team, it will be the winner, and the game will be over.

Article 9

9-1 CAPTAIN: The captain is the only spokesperson on the court during the game.

(I) General Rules of the Game

1. Court Specifications

The NCAA court dimensions are 94 feet (28.65 meters) in length and 50 feet (15.24 meters) in width, and the court area is the same as that of the NBA.

The court is measured from the inside edge of the boundary line, which is 2 inches (5.08 centimeters) wide. There should be at least 3 feet (gi.44 cm) of unobstructed space outside the court, preferably 10 feet (3.05 m). It is legal to replace the 2-inch boundary with a color different from the court floor.

Draw two dotted lines 2 inches (5.08 cm) wide outside the end line, parallel to the end line, with a minimum dimension of 6 feet (1.83 m) from the end line, and no non-participants are allowed in this area.

The radius of the center circle is 6 feet (1.83 m), measured from the outer edge of the self. A dividing line runs across it and meets the two side lines.

The free throw zone is the area consisting of a width of 12 feet (3.66 meters) and a length of 19 feet (5.79 meters) plus a semicircular area with a radius of 6 feet (1.83 meters) (both measured to the outer edge of the line). The far side of the free throw line is 15 feet (4.57 meters) from the surface of the rim.

The ends of the court are marked with 3-point shooting lines, which are drawn by drawing two lines (63 inches = 1.60 meters) parallel to the sideline from the end line, each 63 inches (1.60 meters) from the inside edge of the sideline, and intersecting with an arc of a circle centered on the center of the basket and with a radius of 19 feet, 9 inches (6.02 meters).

The NCAA's 3-point shooting line is the same as the WNBA's 3-point shooting line. shooting line is the same as the WNBA's.

Two additional lines 2 inches (5.08 cm) wide and 3 feet (91.44 cm) long (28 in = 8.53 m from the inside edge of the end line) are drawn on the outside of the sideline to serve as markers for the coaches' area.

The specifications are shown in Figures 1 and 2.

2. Duration of the match

The match will be played over two halves of 20 minutes each, with a 15-minute break in between. Each tiebreaker period is 5 minutes.

Play begins each half-time when the ball first becomes live. Each half-time game ends when time expires, except in the following cases:

. A shot is in flight or a player taps the ball into his side's basket in flight;

. A scrimmage or an infraction occurs near the end of the clock and the game clock is not stopped before the end of the clock;

. A foul occurs near the end of time and the game clock is not stopped by the timekeeper before the end of time; or A foul occurs after the end of time but the ball that was shot or tapped to the home basket is in flight.

If the teams are tied at the end of the second half, play shall continue without changing the basket. There shall be a one-minute break during the tiebreaker until a winner is determined.

Each tiebreaker period shall be five minutes in length and shall be an extension of the second half.

3. Teams

Each team consists of 5 players, 1 of whom is the captain. The match must have 5 players to start. If other team members are no longer eligible to play, the game may continue with fewer than 5 players on the field. If a team has only one player left, the game is lost for that team.

4. Definitions

(1) Basket

A team's home basket is the basket into which a player of that team attempts to put the ball.

The NCAA and NBA rules define the home side of the basket in exactly the opposite way that the FIBA rules provide. With this in mind, FIBA included the definition of a basket in the first article of the 1998-2002 rules to facilitate the worldwide implementation of the FIBA rules.

In NCAA men's games, the visiting team shall have the right to select and practice with a ball basket, which shall be exchanged during the second half of the game.

In NCAA women's games, teams shall practice warm-ups and play the first half of the game in baskets that are farther away from the team's bench area and shall exchange baskets for the second half of the game.

If a referee makes a mistake in allowing a team to go in the wrong direction, all points scored, fouls incurred and time expended when the mistake is discovered shall stand and play shall continue in the correct direction.

(2) Interference with Shot

Interference with shot occurs when:

A player touches the ball or any part of the basket while the ball is on or in the basket;

A player touches the ball when any part of the ball is within an imaginary cylinder with the bottom of the rim as the base of the rim; or reaches underneath the rim, goes through the basket, and touches the ball before it enters the cylinder.

(3) Blocking and Charging

Blocking, an illegal physical contact that impedes an opposing player's progress.

Collision, an illegal physical contact that propels or moves into the torso of an opposing player.

(4) Extra Penalty Shot

The extra penalty shot is the 2nd free throw. When a player commits an ordinary foul, starting with that team's 7th foul (including encroachment fouls, unethical and contact technical fouls that occur during each half-time period), an extra free throw is awarded to the opposing team (except for fouls committed by the player in control of the ball) as long as the 1st free throw is successful.

For men's games, beginning with the 10th foul of each half, two free throws are awarded to the opposing team for each common foul (except for a foul by a player in control of the ball).

Note: An ordinary foul is a general encroachment foul, which is neither a serious foul, an intentional foul, a foul on a player who is shooting the ball, nor part of a double foul or a mob foul.

(5) Incidental Contact

The occurrence of contact is not necessarily a foul. When 10 players move quickly on a limited field, some contact is sure to occur.

Once contact occurs in an opposing team's effort to steal the ball, or when both players are in favorable offensive or defensive positions, it is incidental, even though the contact may be violent.

Contact shall be considered incidental when it does not interfere with the movement of an opposing player in the normal course of defense or offense.

Coverage out of view of an opposing player, where the opposing player may make unintentional contact with the covering player, and where the contact may be severe if the opposing player is running fast, shall be considered incidental as long as the opposing player does stop (or attempts to stop) and go around the coverage at the time of the contact.

(6) Time-outs to be registered

In a regular game, each team is entitled to request five time-outs to be registered.

A single timeout to register shall not exceed 75 seconds. after 60 seconds, a signal shall be given to remind the team to prepare for the game, and after 75 seconds, a signal shall be given to restart the game.

(ii) Infractions and their penalties

1. 3-Second Rule

When a team is in control of the ball in the frontcourt, a player of that team shall not be permitted to remain in the portion of the penalty area between the far side of the free-throw line and the end line for a period of three seconds. A player in the restricted area is permitted to dribble or turn in a shot with less than three seconds remaining. If a player substitutes a pass for a shot, the player shall be declared in violation.

2. 10-Second Rule

(Men) A player may not (his team may not) control the ball in his backcourt for up to 10 consecutive seconds.

For example, if A1 has been dribbling the ball in his backcourt for 8 seconds, when he passes the ball to A2 in the frontcourt, and while the ball is in the air, 10 seconds have elapsed, and the referee declares an infringement, awarding the ball to Team B to throw an out-of-bounds ball close to the spot where A1 passed the ball.

3. 35-Second Rule and 30-Second Rule

In a men's game, a team controlling the ball must shoot within 35 seconds.

In the women's game, a team must shoot within 30 seconds after taking control of the ball.

The ball must leave the shooter's hand before the allotted time and the ball must touch the rim or go into the basket.

4. BALL BACK IN THE BACKCOURT

A team controls the ball in the frontcourt, a player of that team makes the ball go into the backcourt, and a player of that team may not touch the ball first in the backcourt. A pass in the frontcourt that is played into the backcourt by a defender may be regained by both teams.

5. Elbow Swinging

A player may not swing his arm or elbow excessively, even if there is no contact with an opposing player.

For example, B1 swings his arm and elbow violently as A1 shoots the ball toward Team A's basket and does not make contact with any of Team A's players. The referee shall immediately blow the whistle, but the ball does not become dead until the shot is clearly hit or miss. If the shot is successful, the score is counted and the violation is ignored. If the shot is unsuccessful, the ball is awarded to Team A for an out-of-bounds throw-in near the B1 violation.

6. Heavily Defended

A player in control of the ball (not dribbling) who is heavily defended (within 6 ft. = l, 83 m) for more than five seconds is in violation of the rules.

For men's games, front court only.

For women's games, anywhere on the field.

7. Ball Interference

. A player shall not touch the ball or the basket when the ball is on or in either basket. The ball is considered to be in the basket when any part of it is below the level of the rim.

. A player may not touch the ball when it touches the cylinder with the rim as its base.

. When the ball passes through the basket from below, players must not touch the ball even if it is outside the cylinder.

. In shooting, a player must not touch the ball when it is in downward flight and the whole of it is above the level of the rim and threatens to enter the basket.

. A player shall not touch a ball that is tapped by a player toward his basket when the ball is in downward flight and the entirety of the ball is above the level of the rim and threatens to enter the basket.

Violation of the above is an infraction and shall be dealt with in accordance with the relevant penalties set out in the rules.

(3) Fouls and their penalties

. Changing the designated starting lineup;

. Exceeding the allotted five (5) players in a game;

. Exceeding the rated time-outs;

. A substitute entering the field without reporting to the recorder or without being greeted by the referee.

. Accepting a foul that should be registered against a fellow player;

. Pretending to be fouled;

. Inciting a bad crowd reaction;

. Deliberately or severely contacting an opposing player when the ball is dead.

The penalty for this type of non-contact technical foul involving unethical behavior by a player is to award the opposing team two free throws and possession of the ball. This technical foul counts toward the player's 5 fouls and the team's additional free throws. A second unethical technical foul shall be considered a serious technical foul and ejection from the game.

The team bench personnel (coaches, substitutes, team service personnel) and team attendants shall be awarded one technical foul for the following:

. Talking to the referee without courtesy;

. Attempting to influence the referee's call;

. Using profane behavior or vulgar, insulting language;

. Playing musical instruments while the game is in progress.

The penalty for this type of technical foul involving unethical behavior by team bench personnel and accompanying team personnel is to award the opposing team two free throws and possession of the ball. This technical foul counts as 5 fouls for the replacement player (even if that player is not playing at the moment) and additional free throws for the team.

All of the above unethical technical fouls shall also be registered with the coach or assistant coach. Two (2) unethical technical fouls awarded to team bench personnel shall be considered serious technical fouls and ejected from the game. A coach or assistant coach shall be ejected from the game after 2 technical fouls have been awarded to the coaching staff or assistant coaches or after 3 team bench technical fouls have been awarded to the coaching staff or assistant coaches.

The penalty for a serious technical foul is the awarding of 2 free throws and possession to the opposing team. The offender shall be automatically removed from the game.

Team bench personnel must remain in the coaching area except for activities permitted by rule.

Any serious technical foul or serious encroachment foul (meaning fighting, a serious encroachment foul when the ball becomes live, a serious technical foul during a dead ball) called on a coach, team member, team attendant, or person accompanying the team shall result in 2 free throws being awarded to the opposing team, and the offender shall go to the team's lounge until the end of the game.

2. Infringement Fouls

The NCAA rules and penalties for infringing fouls are as follows:

A player shall not pull, push, tackle, or trip an opposing team member; impede the progress of an opposing team member by stretching the arms, shoulders, hips, knees, or by bending the body into an abnormal position; or use any roughness technique.

A player shall not make contact with an opponent with his hands unless the contact is solely with the hand of the opponent holding the ball and is incidental to an attempt to steal the ball. It is unlawful to place a hand on an opponent so as to impede the opponent's freedom of movement. It is unlawful to extend an arm other than vertically so as to impede an opponent's freedom of movement when contact occurs. A player may not use his forearms and hands to stop an opposing player who is coming for the ball while dribbling or shooting. In the event of a critical hit by an opponent, a player may place his hand or arm in front of his face or body to protect himself and absorb the impact.

Contact caused by a defensive player from behind the player with the ball is a form of pushing. Contact caused by the momentum of the shooting player is a form of ramming.

A dribbler shall not charge an opposing player in the path of the dribble or attempt to dribble through between two opposing players or between an opposing player and the boundary line unless there is a reasonable opportunity in the space for the player to pass without contact. If a dribbler's head and shoulders have passed an opposing player without contact, further contact is the primary responsibility of the opposing player. If a dribbler has established a straight path, the dribbler cannot be pushed out of that path, but if an opposing player has established a legal defensive position in that path, the dribbler must change direction or stop dribbling to avoid contact.

A player covering outside the field of view of a stationary opposing team member must leave a normal one-step distance; when covering within the field of view of a stationary opposing team member, the covering team member may approach the opposing team as close as he or she wishes without making contact; an opposing team member, when moving, must not occupy a position too close to the opposing team to enable the opposing team member to stop or change direction in order to avoid contact; and, after taking up a legal covering position, must not move to maintain the legal defensive position. After taking up a legal covering position, cover may not be maintained by movement unless the covering player is moving in the same direction and path as the opposing player.

The penalty for an encroachment foul is as follows:

Register a foul against the offending player, and if the foul is the player's fifth (including any encroachment, unethical, and contact technical fouls), or,

If it is an aggravated foul, the offending player shall be disqualified from the game.

The free throws awarded to the offended player shall be as follows:

l Free throws:

. For a foul on a player attempting a shot, which is successful;

. For each non-serious foul that is part of a cluster foul and is not committed by a player of the controlling team, regardless of whether the fouled team is in the midst of an extra free throw.

2 Free Throws:

. A foul on a player attempting to shoot a free throw, which is unsuccessful;

. For an intentional infringing foul or a serious infringing foul and awarded to the offended team for throwing an out-of-bounds ball close to the spot where the intentional infringing foul or serious infringing foul occurred;

. (a) For any single serious technical foul and the award of an out-of-bounds throw to the offended team at either end of the line of scrimmage;

. (Women) A blocking foul against a player who jumps up to shoot, if the shot is missed;

. (Men) For each common foul (other than a foul by a player in control of the ball), starting with the team's 10th foul (which is the result of a combination of intrusive fouls, unethical and contact technical fouls in each half-time period);

. Each serious foul for a mob foul and the award of an out-of-bounds kick to the team that was violated;

. For mob fouls (except when an offended player attempts to make a 3-point shot and is unsuccessful), if either foul is intentional or serious shall be awarded to the offended team for the out-of-bounds throw.

3 Free Throws:

. A foul is committed on a player attempting to make a 3-point shot and the shot is missed. If the foul is intentional or serious, also award the violated team the out-of-bounds throw-in close to where the foul occurred.

ADDITIONAL FREE THROWS:

For each ordinary foul (except for controlling team players), starting with the team's 7th foul (each half-time infringing foul, unethical, or contact technical foul), as long as the 1st free throw is successful.

No free throws:

. For every ordinary foul that occurred before the additional free throw rule was in effect;

. A foul committed by a player of the controlling team;

. For fouls committed by both teams, even if one or both are serious or intentional
